Welcome to the Summer 2011 Har-Tru Court Maintenance Catalog and Newsletter. Hopefully

youreceivedandbenefittedfromtheReconditioningCatalog and Newsletter sent out this spring. This edition focuses, as the title indicates, on court maintenance and the appropriate routines and tools for keeping your courts performing their very best each and every day. As always, we are interested in your feedback. Send us an email to let us know if what we included was helpful and made your job easier.

Har-Tru Court FundamentalsThe maintenance of a Har-Tru court begins with

some simple routines. These routines, though mostly quite stable and consistent, are a bit like driving a car, whereas the road alters its appearance and direction causing the driver to slow down, speed up or subtly adjust the wheel, similarly those who managecourtsmakefineadjustmentstosuittheconditions they face. To complete our purposes herewewillbreakmaintenancedownintofivecategories and spend some time discussing each one and suggesting tools and routines to assist. These categories are:

• Compaction – How to establish, maintain and alleviate it

• Grooming - Keeping courts smooth and level• Watering – Maintaining optimal hydration• Playing lines – Keeping them level with the play-

ing surface• Growth - Prevention & elimination

Before getting into these topics it’s important to make a quick review of how a Har-Tru court is constructed, as this lays an important framework of understanding around the impact a change in the

maintenance routines can produce on playability.Har-Tru courts are constructed with a stone base that varies in depth but serves primarily to provide a stable foundation for the Har-Tru surface and to take on and store water. As such a proper base is stable, compactable and remains porous at all times. On top of this base a one inch layer of Har-Tru is installed. With the addition of an appropriate amount of water and manual compaction the Har-Tru surface becomes veryfirmandinessencethecourtreacheswhatmight be described as an optimal condition for play (Note: While Har-Tru Sports continues to strive to develop parameters and ranges that could measure optimal,nosuchdefinitiontoourknowledgepresently exists, and as we survey all constituents – owners, managers, teaching professionals, tennis players, maintenance personnel and tennis court builders – what is optimal varies nearly as much as the number of courts in existence). Changes to the amount of water stored in the surface and base layers and/or changes in the level of compaction are predominantly what alter playability. Consequently thefirstthreeofthefivetopicsforthisnewsletterand catalog focus on just this.

COMPACTION - How to Establish, Maintain and Alleviate It

PreferencesvarywidelyonhowhardorfirmaHar-Tru court should be. Part of the reason for this is that there is a very clear delineation for

when a court is too soft (i.e. the ball won’t bounce) but not so when a court is too hard. Consequently you end up trying to determine the difference between firmandtoohard.Manydopreferaharder,fastersurface as it allows for a more aggressive style of play. In our experience complaints about a court being too hard arise more from a court becoming slippery than due to speed of play or hardness of surface. In the end a facility manager can only ask members for feedback on court conditions and establish routines that keep the majority of the playing population content.

The question then becomes how to modify or vary surface compaction. Have you ever heard of the Proctor compaction test? It is a lab test used to determine the optimal moisture level which will allow

a soil to become most dense. A Har-Tru court, like all soils has an optimum moisture level at which it can be compacted to its greatest level. Vary the moisture content and the degree of compaction will vary. Vary the amount of weight being used to add compaction and the amount will vary. In essence you are driving air out of the court and replacing it with water and this allows you to decrease the void spaces making the court tighter. Add too much water and the court becomes unstable, much like an outdoor court after a winter of freezing and a spring of rain. Add too much weight and a court locks up very hard and tight. Keep constant moisture present, as do modern, sub-surface irrigation systems, and courtsgetprogressivelyfirmerovertime with the top layer in particular getting very tight and hard.

Adding Compaction:When trying to make a court harder and faster we recommend rolling the court once or twice a day until the desired conditions are achieved. The heavier the roller, the fasteracourtwillfirmup,howeverwedonotrecommendexceeding a rolling weight of 1200 LBS for daily maintenance purposes. Never use vibratory compactors for Har-Tru maintenance. The rolling will always be most effective when there is ample water present in the surface and base layers, thereforetrytorollafterarainorfirstthinginthemorningafter the irrigation system has run over night. Courts with sub-surface irrigation can be rolled anytime.

Alleviating Compaction:The Har-Tru surface needs to breathe, that is it needs to be able to exchange air and water. When it gets too hard it can no longer do this effectively. Additionally courts will take on a bald appearance and what loose top dressing is left gets worn and slippery. The best option here is to utilize aggressive tools on the court daily to soften the top layer up and keep it from hardening back over. We have developed tools that are sharpandheavy,specificallytothisend,mostofwhichcanbeused as part of your daily maintenance regimen. These tools – namely the Har-Tru Gator Rakes, the Steel Bristle Drag Brush, and the Court Devil - break through the hardened top layer and regenerate the loose sliding material that keeps traction safe and consistent. These tools can be used as often as time will allow and are particularly important for daily use on HydroCourts and indoor courts. It probably goes without saying that you should never roll courts that are already too firmasthatwillonlyexacerbatetheproblem.

Maintaining Compaction:Once you have found a level of compaction you consider optimal this can most often be maintained on above ground irrigated courts with only occasional rolling, particularly after adayofsteadyrain.HydroCourtsmaybenefitfromarollonce a month to keep the lines down but otherwise the focus on these courts should be on using aggressive tools at regular intervals to keep the desired conditions in place. Be ready to modify routines as conditions warrant paying close attention to the change of seasons, which are the times when conditions change most rapidly. It’s not unusual to have to roll every day in the spring only to need to switch to aggressive grooming tools in summer and add rolling back in for late fall.

ROLCPP04 - 48” CourtPac Pro RollerROLCPP05 - 60” CourtPac Pro Roller

Nearly30yearsago,BobLeeintroducedhisfirstmainte-nance roller, the Proline, to the tennis community. It is with that legacy of tennis court innovation that we are so proud to introduce the newest version of that maintenance roller, the CourtPac Pro.

While the CourtPac Pro may look a bit similar to its predecessor, the 4’ and 5’ Proline Roller, that is where the similarities end. The Pro is powered by an ultra-reliable, 5.5HP Honda engine and driven by a fan-cooled HydroGear hydraulic transmission. This is the same transmission used in our recently redesigned CourtPac solid drum construction roller, as well as tens of thousands of industrial lawn mowers throughout North America. The redesign also incorpo-rates improved comfort features for the driver. CourtPac Pro userswillbenefitfromafullyadjustable,cushioned,high-backseat and newly designed foot deck. The new seat offers comfort and improved sightlines, and when coupled with the new, skid-resistant foot deck design, makes the unit, by far, the safest and most easily maneuverable unit available on the market today.

The roller guard was redesigned in 2008 and allows the user to see the roller as you are moving to determine if the court is too wet to roll by seeing the amount of material that is sticking to the roller. The Pro’s unique rolling system uses a series of 14” wide cylindrical roll sections, allowing each section to turn independently as the driver makes turns on the Har-Tru court. This system eliminates the tearing or “biting” that some solid section rollers created when making similar turns.

Much like the Proline roller of yesterday, the CourtPac Pro has two fully adjustable grooming brushes for leveling and smoothing your Har-Tru court, and a polyurethane scraper to keep the roll sections clean of granular build-up.

The CourtPac Pro was developed with safety, ergonomics, and easy operation in mind. It’s a relatively simple machine with fewer parts to as-semble and little, if any, adjustment needed by the owner. The Pro was designed to incorporate the needs of the Har-Tru clay court owner, while answering the wants and desires of past Proline roller owners.

All CourtPac and CourtPac Pro rollers carry an industry best, 2-year warranty.

GROOMING - Keeping Courts Smooth and Level

During match play the Har-Tru surface can get moved around and scuffed up. The purpose of sweeping or grooming the court is to smooth

thetopdressingandfillinanydivotsandscuffs.Thiseliminates bad bounces and makes traction more consistent for the next set of players. Grooming after heavy play is particularly important for courts watered from above, as these types of courts tend to have more loose top dressing material on the surface.

With this information one might think it best to sweep a court after every play session. This is not entirely true. Sweeping a court dries it out, as every time you turn over surface material water evaporates. If a court is swept multiple times without being watered, by the end of the day it is usually dry, dusty and slippery with an abundance of loose material that creates bad bounces. Consequently you should only sweep a court if it will be watered afterwards. If you own a HydroCourt, where moisture is replaced as it evaporates, you can brush as frequently as desired.

We offer grooming tools that vary widely in aggressiveness. Some are designed to dig into the court surface and generate sliding material (these are what we would call aggressive) while others disturb only enough of the loose surface material to smooth the court out (See Chart 1). Aussie Clean Sweeps have been shown to cause less drying than conventional drag brushes so we strongly recommend using them for summer maintenance. For HydroCourt, the more sweeping the better, particularly with aggressive tools such as the Har-Tru Gator Rake or Steel Bristle Drag Brush.

For deep scuffs or grooves that appear from toe draggers or uneven drainage, hand raking with the serrated edge of a Lute Scarifierwillbethebestwaytosmooth out the surface. Additional Har-Tru surface can be added as needed in this situation.

Water – Maintaining Optimum Hydration There is no doubt that a properly hydrated court is a more consistent court, both to play on and maintain. This is the reason so many are switching to HydroCourt. With a HydroCourt, once optimal water levels are found the court takes what it needs and there are no wet/dry cycles that courts with timed irrigation systems experience. There is also no need to shut courts down midday for watering. If you water with a sprinkler system it’s critical to provide the court with enough water to stay in good shape until the next watering cycle. Remember that the Har-Tru surface and base layers act as a reservoir for water. If you continually dry out this reservoir and don’t replace the water being lost to evaporation, the court gets progressively dryer until it becomes impossible to catch up without the help of some rain. To avoid progressively drying out the court we recommend watering several times over night for an interval just long enough to soak the courts. Leave time on the clock to allow this water to soak in and then repeat the process, preferably 3-4 times (see a sample watering schedule in Chart 2). During the day find at least one time slot where the courts can be shut down and thoroughly soaked. Otherwise tennis players coming at the end of the day will have very dry and dusty playing conditions with many bad bounces. Since water is the most essential ingredient for keeping your court in good shape, a sprinkler system that provides inadequate water and/or uneven distribution may be the single biggest maintenance headache a Har-Tru court owner can have. There are several critical ingredients to understand when designing and maintaining your watering system, namely the water pressure and volume you have and the size of your incoming water line. With this information you can begin to devise a strategy to improve water distribution and maximize the amount of water you can get on the court in a short period of time. The data will allow you to select the most appropriate sprinkler heads, valves and controllers for your situation. There are many old, outdated, irrigation systems out there and it may make sense to have your system evaluated by a professional. Our Consulting Services department can always inspect what you have and assist you in drawing up a plan to improve it.

Our Consulting Services department can always inspect what you have and assist you in drawing up a plan to improve it.

Lastly, don’t forget that Magnesium and Calcium Chloride are great products to supplement your above ground irrigation system (MAG & CaCl should not be used on HydroCourts). Both products chemically attract water, pulling it out of the air and keeping it from evaporating from your court. Many use Magnesium & Calcium on a weekly basis to get through hot, dry bouts of weather. An application of 100 LBS per court applied with a broadcast spreader or thrown out with a shovel is all it takes. The effects of Calcium and Magnesium are temporary and only last 2-3 days so it’s best to apply it just prior to a time of heavy court use (where you may not be able to shut down to apply much water) and water it until it dissolves.

Often overlooked when it comes to maintaining optimum hydration is drainage, or how well water is getting off the court. Do your courts stay wet for a long time after a rain storm? Consider this. Har-Tru courts are porous and constructed with a moderate slope to allow for drainage both through the court (into the base layers) and off the court. Over the course of a playing season both ofthesecanbecomeimpairedandcreatedifficultyforthosemaintainingcourts.

Drainage Through the Court

If courts get too hard and impermeable water will not penetrate the surface layer and work its way into the base. Two things might indicate your courts are too hard in select areas or just in general: 1 - Puddles form in low spots (often the high play areas like the baselines or areas washed out over time by sprinklers)and take and excessive amount of time to disappear; and 2 – your courts consistently look bald after heavy rain. In reference to number one, a low area becomes a spot where Har-Tru finessettleandharden.Sincewatercannotgetthroughhere the only way it goes away is when it evaporates. This can be resolved by scarifying and patching. Shut the court down for a couple of hours, thoroughly scratch up the areawithaLuteScarifierorHar-TruGatorRake,fillinandlevel with new Har-Tru, lightly hand water, and hand roll. Keep the court closed until the patch has hardened. If you don’t have time for this another option is to purchase aSuperSopper.Thisisaclaycourtsqueegeespecificallydesigned to mop up these pesky puddles.

As far as number two goes, a court that consistently loses its top dressing during a heavy rain might be an indication that the surface layer has crusted over and water does not penetrate. Using a Gator Rake, Steel Bristle Drag Brush

and Court Devil will help re-open the pores in the court and allow water to be absorbed rather than sheeting off and taking Har-Tru with it.

Drainage Off the Court

Over time the slope of a Har-Tru court diminishes as Har-Tru washes from the high side of the court to the low side. While it takes many years to happen, as it does, off the court drainage slows down and eventually stops. This is often exacerbated by facilities planting decorative shrubs and trees and/or placing mulch around the courts in such a way that the water is trapped on the court at the low end. If your courts take a long time to dry after a rain it makes sense to observe drainage by watching where the water goes during a rain storm. If the court drains very slowly, particularly compared to other courts in your area, watch the low end of your courts and see if the water is getting dammed up. If you have plantings that are higher than the curb around your court, or the low end curb is buried and no longer visible, these are pretty good indications of a problem that needs to be addressed. Options include scraping off material on the low end of the court, re-grading your courts, clearing blockage that lies outside the court and installing channel drains. Sometimes consulting with an expert here is the best way to consider remedies.


SUPER SOPPERDRY04 - 7 gal. Mackerel DRY05 - 14 gal. Dolphin

The Super Sopper takes care of total water removal by lifting water off the court using an ingenious col-lection system that holds up to 14 gallons at a time. How does the Super Sopper work? Water is lifted from a court using a sponge-covered barrel and is strained into the center of the porous barrel where it can be held and later emptied.The Super Sopper is perfect for courts that tend to puddle in low areas and need total water removal to get courts in play fast. It can be used on both hard courts and Har-Tru courts. Replacement sponges available.

Irrigation

New this year we are offering equipment from three leaders in irrigation. Why? Facilities have individual needs and preferences and we want to provide a choice. All the heads we offer have stainless steel risers and are highly suited for tennis court sprinkler systems. Here are a few notes that might help you make a selection:

1. Ascertain the pressure and volume of your water source and the size of your incoming line. Then utilize the chart below to see what heads are an option.

2. The higher the model numbers the more water the head will put on the court and the further the throw radius.

3. The Rainbird Falcon Series has a different head for full circle (FC) and part circle (PC) rotation so you want to select the head that meets your needs.

4. HS means it is a high speed head. High speed heads turns more quickly than standard heads allowing them to distribute more water per watering cycle. Due to the faster rotating speed the distance they throw the water will be reduced.

Still not sure what you need? Har‐Tru consultants are available to answer your questions by phone at 1‐877‐4HARTRU. We also have consultants who will come to your facility and analyze your system and help you design a new one. Let us do the work!

PLAYING LINES - Keeping them level with the playing surface

Maintaining the playing lines should be a part of your daily or weekly routine. There are several factors that affect how well the lines

aresecuredandhowflattheyremainagainstthecourtsurface. One of these factors is the daily maintenance regimen itself. Every time a court is swept some of the Har-Tru surface that is carried in front of the brush gets pushed under the lines. Over the course of a playing season this will raise the lines enough to create bad bounces and sometimes even present a trip hazard. Lines that are high catch the Aussie Clean Sweep causing it to drop piles of Har-Tru and debris and they are easy to catch with the Har-Tru Gator Rake or Steel Bristle Drag Brush and pull right out of the court.

Another factor affecting playing lines is heavy rain. As water runs down the slope of the court it runs into and over the lines and can wash out some of the Har-Tru on both sides, exposing the edge of the tape. Once

again you have a spot that creates a bad bounce and could easily cause a player to trip.

So how do we maintain the playing lines? Inspect lines daily or weekly for high spots, curled edges, nails coming up and loose sections. You can do this while grooming the court and make a note to address it later. Occasional rolling on all types of courts will help keep lineswellsecuredandflat.Additionally,makesureyouvary the direction in which you sweep the court. If you sweep side to side in the morning sweep from end to end in the afternoon. Maybe even sweep diagonally on occasion.

For lines that are high, pull the nails out up to two feet on either side of the high section and use a trowel to scrape Har-Tru out from underneath the line. Then

re-secure it to the court surface and hand roll. If necessary you can pull the entire baseline and scrape it down with the serratededgeofaLuteScarifierpriortore-securing.Thismay take one hour but it will make an incredible difference for tennis players.

For areas that are high due to washouts, add Har-Tru on eithersideofthelineandspreaditevenlybyrunningtheflat

edgeoftheLuteScarifierbladerightacrossthecenterofthebaseline (push the blade don’t pull it or you will catch nails). A 48” blade works better for this task than the 30” blade. Once the material is evenly spread, hand water and hand roll. Repeat this process until the problem is satisfactorily corrected. In extremely bad cases pulling the baseline up and patching may be necessary.

GROWTH - Prevention and Elimination

The key word here is prevention! Your court should begin the year without any weeds, moss or algae. Implement routines to keep it that way

and life will be much easier. Growth nearly always takes holdinthelowplayareasfirst.Thismeansthatthetwofeet around the net line and the two feet adjacent to the fence are the most susceptible. The answer is simple, make sure you sweep all the way up to the brick curb on the perimeter of your court every day and scarify these areas once a week. We recently brought a great new product to market as part of the Har-Tru Gator Rake line called the Cart Side Rake that makes this much easier to do. This rake attaches to the side of the golf cart and extends on a spring tensioned arm allowing you to scratch up the edges of your court without ever leaving the cart. It’s a must have as far as we are concerned. Otherwise utilize the 24” Gator Rake, which isanextremelyaggressivehandrake,oraLuteScarifierto scrape out any growth as it appears. Remember to remove anything that you scrape up so it doesn’t seed

the area you just cleaned.

Once growth has taken hold in your court you may need to spray it with something to eliminate it. Moss, weeds and algae all respond to different treatments. Weeds can be killed safely using RoundUp. In our experience moss responds best to a product called Moss Buster which is made from natural plant extracts and is safe and effective. We do not sell anything approved to kill algae on a Har-Tru court but if you water from below with a HydroCourt there is a product called Cutrine Plus that can be put in the boxes to combat it.

If you don’t have a Lawn Wheelie and growth tends to be a problem at your facility you need to get one. It is a tool that makes the application of any type of spray quick and easy as it sprays while it is pushed. It’s perfect for targeting fence and net lines.
