Equipped with two-piece pedestal, theModels "50" and "60" can be furnishedwith a variety of front-wheel equipment,including the adjustable front axle shownleft. It has a maximum oscillatingrange of 14-1/2 to 20-3/4 inches, andfront wheel tread is adjustable from 56to 80 inches in 4-inch steps.

For growers of wide-spaced rowcrops, special long rear axles are avail-able to provide rear-wheel tread settingsup to 104 inches depending upon tiresizes used. Either 38- or 42-inch di-ameter tires are available. Clearanceunder front axle is from 22 to 24 inches;under rear axle, from 24-1/2 to 27-1/2inches, depending upon equipment.

They're completely adaptable 11

Roll-O-Matic Front WheelsBoth the Models "50" and "60" Trac-

tors are available with famous Roll-0-Matic "knee-action" Front Wheels—anexclusive John Deere feature whichprovides easier, smoother operation inpractically every condition. With Roll-0-Matic, the slightest up or down move-ment of either wheel is transferredthrough gears which automaticallyequalize the load on both wheels.

As a result, front-end bounce is cut inhalf and it takes just a guiding hand onthe wheel to operate the tractor in roughfields. Roll-O-Matic is optional equip-ment for tractors with either the one-piece or special two-piece front pedestal.

Adjustable Front Axle

The illustration at right shows oneof the new models equipped with aspecial long rear axle. With 9-42 or 11-42 tires on this axle, you can secure amaximum rear-wheel tread of 104 inchesas shown here, down to a minimum of56 inches or any setting in between.With 10-38 or 11-38 tires on the "50"and either 11-38 or 12-38 tires on the"60," the long rear axle provides a treadrange of approximately 62 to 97 inches.Here is complete adaptability to theneeds of farmers who raise crops grownin wide-spaced rows. The long rear axlecan be furnished for Models "50" and"60" Tractors equipped with adjustablefront axle or single front wheel.

Single Front Wheel

The single front-wheel models areideal for working in irrigated sectionsand in narrow-row crops. Here again,John Deere offers a wide choice of tireand axle equipment. A variety of reartire sizes is available to meet every need.Either regular or long rear axles areavailable to match row spacings desired.Clearance under axle housing is the sameas for the adjustable front axle models.The single front wheel bolts securely tothe two-piece front pedestal. It is easy toput on or take off and is interchangeablewith the other types of front-end as-semblies.

38-Inch Front TreadThe Models "50" and "60" can be equip-

ped with the 38-inch fixed front tread, shownleft, to meet exacting requirements incertain bedded territories where crops aregrown in 36-, 38-, and 40-inch rows. Thisfront end is particularly desirable where fallbedding is followed by re-bedding in thespring. The front tractor wheels straddle theold beds and make it extremely easy tohandle the tractor as the front tires followthe furrows. This fixed-tread front axle boltssecurely to the two-piece front pedestal andis quickly replaced with regular or Roll-0-Matic dual front wheels.

r Great New Engines bring you

J OHN DEERE engineers have worked wonders in stepping up performance of the new "50" and "60"

Tractors equipped with gasoline-burning engines. Theyhave taken a page from the book of airplane and racing-car engine designers and developed a double-barrelledcarburetor that meters the fuel-air mixture in identicalamounts to each cylinder and provides these new trac-tors with Duplex Carburetion. This revolutionary develop-ment in tractor engines—exclusive with John Deere—provides more snap and quicker response . . . outstand-ing economy . .. and smoother engine operation. Be-cause Duplex Carburetion, in effect, provides a car-buretor for each cylinder, you'll find the Models "50"and "60" Tractors start faster in all temperatures, idlebetter, and offer prolonged spark plug life.

Another brand-new feature of the "50" and "60"Tractors is the hot-and-cold adjustment of the manifoldwhich provides for maximum engine efficiency in bothwinter and summer. During warm weather months, thetwo-position adjustment valve is set in the "Cold" po-sition and the burned gases are expelled directly intothe exhaust stack, keeping the incoming fuel mixture atproper temperature. When the valve is turned to the"Hot" position, the exhaust gases are diverted throughchannels surrounding the fuel and air passageways. Thispre-heats each fuel-air charge on its way to the combus-tion chamber to provide more efficient vaporization,more complete combustion, and better all-around per-formance in cold weather.

In combination with new Duplex Carburetion and hotand-cold manifold, the "50" and "60" Tractors offer exclusive cyclonic-fuel-intake. An eyebrow over each in-take valve directs the incoming fuel-air charge down-ward, creating a cyclonic turbulence which insures morethorough mixing of fuel and air, better combustion, max-imum efficiency and greater economy.

A glance at the illustration at right will show you thesemajor engine advancements, but only through a fielddemonstration will you fully appreciate the new powerand economy advantages they offer you.

livelier, more flexible power

"Live"Power Shaft speeds upHE new John Deere "live" power shaft* is a major engineer-ing advancement. It provides continuous power for operating

PTO machines as long as the tractor engine is running—powerthat is completely independent of the transmission clutch.

This great new John Deere feature reduces clogging of equip-ment to the very minimum because you can declutch the tractorand clear the power-driven machine the instant it takes on anoverload—re-engage your clutch in a jiffy and continue on yourway. There's no time lost in shifting to neutral and re-engagingthe transmission clutch in order to operate the power shaft—no declutching and shifting to forward gear before you'reready to go again.

Seldom if ever will you have to get off the tractor and cleanout the power-driven machine by hand because when you de-clutch the tractor and stop taking in more of the crop, the con-tinuous-running power shaft clears the machine before pluggingcan take place.

In extremely heavy conditions, the exclusive low gear in theModels "50" and "60" Tractors and the "live" power shaftmake an ideal crop-saving combination. You can "creep" alongat 1-1/2 mph with the power shaft operating at full rpm, har-vesting heavy crops with minimum loss.

Exclusive DesignThe "live" power shaft on the new John Deere Models "50"

and "60" Tractors is engineered for trouble-free operation,and quality built to give years of service. A sliding gear andshaft transmit power through the power train to a spring-loaded, over-center, wet-disk type clutch. Engaging the clutchdelivers power to the splined PIO shaft which drives the equip-ment.

The power shaft clutch is an outstanding feature. It enablesyou to bring the power-driven machine up to full speed beforestarting the forward travel of the tractor and it completely pro-tects the PTO shaft and cushions shock on the implement.Even with the engine at wide open throttle, you can engage theclutch instantly without damage. The power shaft clutch hasan independent oil reservoir and lubrication system; it operatesin a constant bath of oil supplied by a separate pump.

When the tractor is used for other work, the sliding gearand shaft may be disengaged. Both shift and clutch levers areconvenient to the operator on the tractor seat and are easy tooperate.

"Live" High-Pressure Powr-Trol

"Live" hydraulic power is a big advantage inoperating a manure loader because it saves upto 40% of the shifting and clutching formerlyrequired. Shown above is the Model "60" Tractorwith the new No. 50 Hydraulic Loader.

JOHN DEERE pioneered the application of hy-draulic power to operating tractor-mounted equip-

ment in 1933. This was followed in 1945 by theintroduction of Powr-Trol—the first dual hydraulicsystem to control both integral and drawn tools. Noother hydraulic system has been so enthusiasticallyaccepted by farmers. Powr-Trol has proved to beunequalled for dependable operation in all field con-ditions ... for adaptability to practically every type oftractor-powered equipment on the farm . . . and forits time-saving, muscle-saving and better-work ad-vantages.

Now, in the new Models "50" and "60" Tractors,John Deere brings you "live" high-pressure Powr-Trol—ever-ready hydraulic power that operates completelyindependent of both the transmission clutch and thepower take-off. This outstanding new advantage savesup to 40 per cent of the time and effort formerly re-quired in clutching and shifting gears when operatinga manure loader . . . in hooking or unhooking toolcarrier attachments . . . or whenever the tractor travelmust be stopped and the equipment operated by hy-draulic power.

A second important advantage of "live" high-pressurePowr-Trol is its increased capacity that enables you tohandle heavier tractor equipment. A new-type, directengine-driven pump operates at high speed, providinggreatly increased hydraulic pressures to actuate boththe rockshafts for controlling integral tools and theremote cylinder for drawn equipment.

A Proved Time and Labor Saver

Powr-Trol provides instant, accurate, effortless con-trol of mounted and drawn equipment—furnishes hy-draulic power to angle and straighten disk gangs .. .raise and lower other tools ... or to set them at any de-sired position—all at a touch of your hand, withoutstopping or even slowing down. It's the proved hy-draulic system that saves you time and muscle and in-sures better work on practically every farm job.

Exclusive SIMPLICITYThe greater simplicity of John Deere

two-cylinder engine design is a provedfact. As the illustration at the rightshows, there are only two cylinders, twopistons, two connecting rods—cor-respondingly fewer valves, bearings,rings, and other moving parts to wearand require eventual replacement. Thesame simplicity is carried right onthrough the entire tractor—with fewergears in the transmission . . . only onejoint in the steering mechanism, etc.

ExclusiveSTRENGTH OF PARTS

Extra weight and strength are otherfundamental advantages of John Deeretwo-cylinder tractor design. Parts arelarger, heavier, stronger—bigger pis-tons . . . heavier crankshaft . . . morerugged gears and shafts . . . strongerframe and housing construction. Thetransmission and final drive gears,shown at the left, are typical of theruggedness that enables a John Deere tostand up under the punishment ofgrueling farm work for a longer time.

(14)

Take a Look InskHere's Why Exclusive John Deere

John Deere t cylinder engine design was born back in 1924with the introduction of the first tractor to bear the John Deerename.

Right from the start, the simple, rugged construction of thattractor proved itself.

Here was unequalled simplicity—fewer parts to wear, to cause trouble, torequire eventual replacement . . . greater accessibility . . . easier, lowe•-cost

maintenance. Here was unmatched strength of parts for more dependable per-formance, more years of service.

No wonder more and more farmers bought John Deere Tractors as the yearswent by. No wonder John Deere steadfastly continued to develop and improveupon the "two-cylinder idea"—the totally-different, more practical tractorengine design that set the standards for dependability, economy, and long life.

These same basic advantages are just as important in a tractor today as theywere more than a quarter of a century ago. They're yours to enjoy, yours toprofit by, along with every modern operating feature, when you choose a newJohn Deere Model "50" or "60" Tractor.

ExclusiveWEIGHT DISTRIBUTION

In this phantom iew at right, noticethat the heavy engine parts are locatedwell toward the rear. Notice, also, thatthe weight of transmission, differential,and final drive is carried on the rearwheels, with just enough weight on thefront to insure easy steering and stability.As a result of this better weight dis-tribution, you get maximum traction—there is less wheel slippage to wastepower and fuel . . . more weight formaximum pull in tough conditions

Driving and operating a new Model "50" or"60" Tractor in the field is a constant source ofreal satisfaction which must be experienced tobe fully appreciated.

Gone is the manual effort and time-consumingannoyance of constantly shifting gears and en-gaging and disengaging the clutch to operatepower-driven or hydraulically controlled equip-ment. The new "live" power shaft and new"live" Powr-Trol operate independently of eachother and of the transmission clutch, providingever-ready power as long as the tractor engineis running.

In the illustration at left, notice that the high,centered seat places the operator up, well outof the dust and dirt—in a commanding position.This seat position and the tapered design of thefuel tank offer an almost perfect view of thework ahead and to either side without straining.

The deep-cushion seat is comfortable andfully adjustable and there's a platform withplenty of room for standing to relieve fatigueduring long hours at the wheel or when travel-ing over rough ground. You can stand up aseasily and naturally as rising from a chair, andthe hand clutch gives you complete control ofthe tractor from this position.

All controls are convenient and easy to oper-ate—throttle . . . hand clutch . . . gear shift .. .Powr-Trol . . . power shaft . . . electric starter. . . and differential foot brakes. Directly infront of the operator is a full-view instrumentpanel containing the gauges and a new, easily-reached combination-type switch which con-trols ignition . . . bright front and rear fieldlights . . . bright or dim front lights, and redrear warning lamp. A panel light illuminates theinstrument panel.

Here is operator convenience and comfortsuch as you've never before experienced.

Quick•Change Wheel Tread

A

The new John Deere Quick-Change Wheel Treadis an outstanding feature. It permits quick, easyadjustability of rear wheels for different row spac-ings. There's no more lifting, hammering, or tug-ging; no removal of either wheel; no reversing ofwheels from side to side to obtain the full treadrange of 56 to 88 inches.

As the illustrations on this page show, all youhave to do is jack up one wheel at a time ... loosenthree clamp screws which hold the wheel in posi-tion . . . tighten two jack screws to free the wheel

on the axle . . . and turn an adjusting nut to move thewheel in or out. It takes but little effort to obtainthe exact settings desired. To relock, merely backoff the jack screws and tighten the clamp screws.

The maximum travel of each wheel on its axle is8-1/2 inches, giving a wheel-tread range of 17inches in each of four rim settings. By simplychanging the position of the rim on the wheel, youcan obtain any wheel-tread setting between 56 and88 inches. Here's another great John Deere time-and labor-saving feature.

Unexcelled ViewJohn Deere General-Purpose Tractors always

have led the field in providing a clear, unob-structed view of the work from a natural, relaxedposition on the seat.

The high, centered seat location and thetapered fuel tank have been retained in the newmodels. To improve visibility still further, theair intake stack has been removed and the intakerelocated under the grille. In addition, the ex-haust muffler has been moved to the right, to pro-vide center-line visibility.

If you need maximum clearance for workingunder low sheds and through low doorways,you can quickly replace the regular exhaust muf-fler with the special rear exhaust muffler, shownin dark green shade in the illustration below.It takes just a few minutes to make the change.The exhaust fumes are carried to the rear anddischarged away from the operator.

This attachment is ideal when operating amanure loader or doing odd jobs around thefeed lot where extra clearance is needed. A metalcap, which replaces the upright exhaust stack andcovers the hood, is furnished with the rear ex-haust muffler.

This field scene shows the unexcelled view you'llenjoy ahead and to either side. Notice the newcenter-line visibility. Notice, also, that the culti-vator has been designed with a minimum of bracebars in line of view.

New Effortless Steering and Ex(give you unexcelled ease of

You'll really appreciate the new, effortless steering

that's been engineered into the John Deere Models "50"

and "60" Tractors. It greatly reduces fatigue—you can

make round after round, spend long hours in the field

at the wheel without strain or the feel of tired, aching

muscles. Even when the tractor is standing still, the front

wheels can be turned with very little effort.

The illustration above shows a cutaway of

the new steering mechanism. The worm and

a full gear form the only joint in the entire

steering mechanism. Both are highly finished

to reduce friction; fully enclosed and auto-

matically lubricated. The full gear is rever-

sible for double life. Increased gear ratio

and the ball-thrust bearing at the base of the

pedestal on both models are additional im-

portant factors in easier steering.

( 2 8 )

Here's How It Works

This cutaway view shows how Roll-O-Maticoperates. The slightest up or down movement ofeither wheel is immediately transferred throughgears, which automatically equalize the load onboth front tires. Here, the right front wheel hasencountered a field obstruction which has raisedit, automatically forcing the other wheel downand allowing the tractor to ride over with ease.This construction is simple and fool-proof.Forged steel gears and knuckles are built witha margin of strength to stand up under greatershocks and strains than will ever be encounteredin normal field operations.

Wheels are reversible to give greater clearanceand prevent "balling up" in extremely muddyconditions.

lusive Roll-O-Matic Front Wheels

You can't help but notice the difference—in theeasier, smoother, surer-footed way the tractor steersover rough ground . . . on sidehills . . . in furrows... on top of beds ... along the contour ... in practi-cally all operating conditions.

There's no fighting the wheel, no creeping, noweaving from side to side. Steering is much easierbecause the load is always equalized between bothfront wheels. Riding is greatly improved because up-and-down movement of the front end is cut exactly inhalf as the tractor travels over rough ground. Withjust a guiding hand on the wheel, the tractor literallyclimbs out of furrows . .. "walks" right over ob-structions . . . operates in rough fields with greaterstability.

At the left, are two John Deere Tractors. Oneis equipped with conventional rigid front wheels;the other with Roll-O-Matic. The left front tiresof both are resting on a rock 5 inches high. Noticethat the entire front end of the conventional tractorhas been forced to rise the full 5 inches and that onetire is taking the full load. Now look at the tractorequipped with Roll-O-Matic. Here, the rise is only2-1/2 inches—exactly half that of the conventionaltractor—and each tire is taking its full share of theload.

By minimizing the up-and-down movement of thefront end and equalizing the load between both frontwheels, Roll-O-Matic provides a smoother, morecomfortable ride, and greatly increases front tirelife.

B OTH THE Models "50" and "60" Tractors are equippedwith a six-speed transmission controlled by a single shift

lever. There's a practical speed for every job from a mere crawlof 1-1/2 mph to a high of 10 mph on the "50," and 11 mph onthe "60" for transporting.

The "creeper" gear of 1-1/2 mph is ideal for drawbar jobsrequiring slow travel speed, and for maintaining maximumpower shaft output when operating power-driven machines atslow speed. It is a decided advantage in transplanting . . . inoperating a combine, corn picker, or ensilage harvester undercertain conditions ... in spraying fruit trees ... in close culti-vation of specialty crops ... and in other conditions requiringthis slower speed for best work.

Accurate Speed Control

This new-type speed-con-trol lever is mounted on theright-hand side of the in-strument panel for easier ac-cessibility. Greater leverageprovides smoother opera-tion and more accurate con-trol of engine speed. Sealedmounting insures trouble-free operation.

YOU'LL FIND the John Deere hand

ience feature. It eliminates the inconven-

ience of mounting the tractor to engage or

disengage the clutch when working on belt

jobs. It gives you complete control of the

tractor while standing on the platform—

there's no need to sit down to operate the

clutch. It makes hitching to drawn imple-

ments a one-man job.

In the new John Deere Models "50" and

"60" Tractors, the clutch lever is 6 inches

longer. It's easier to reach, especially when

standing and easier to operate because it

provides greater leverage.

CONTROLLED SHUTTER

BIG-CAPACITY FUEL TANKThe Models "50" and "60" Tractors are equipped with

big-capacity fuel tanks, assuring an ample fuel supply for along half-day's operation even in the most severe conditions.Equipped with gasoline engine, the Model "50" holds 16gallons and the Model "60," 20-1/2 gallons. Equipped for all-fuel engines, the fuel tank capacities are the same but a one-gallon auxiliary tank containing gasoline for starting pur-poses is added. An accurate, inexpensive fuel gauge can befurnished as extra equipment.

Safeguarded Quality Constructionwall the way through

In every respect, the new John Deere "50"and "60" Tractors are as safeguarded in de-sign and as automatic in operation as modernengineering methods can devise.

The complete enclosure of engine, trans-mission and differential in oil-tight, dust-proof cases . . . the effective sealing of mainbearings, front wheel bearings, axle bearings. . . the oil-wash air cleaner . . . full-flow oilfilter . . . efficient fuel strainer—all safeguardthe new models against the entrance of dustand dirt and prolong tractor life.

The precision working parts of the enginesare automatically lubricated by a full-pressure,force-feed system. Lubrication of the trans-mission and differential is thorough, unfail-ing in its operation, and entirely automatic.

Before any oil can reach pistons, bearings,and other parts of the engine, it is forced throughan efficient, replaceable full-flow oil filter whichremoves abrasives to maintain the oil in goodcondition.

Automatic CrankcaseVentilation

This exclusive crankcase ventilation system pro-vides a constant circulation of air throughout thecrankcase as long as the engine is running, to expelharmful fuel vapors and prevent the formation ofsludge. The cutaway illustration above shows howthis improved automatic ventilation system works.Air that has been cleaned by passing through theair cleaner is drawn through a pipe—tapped in theair inlet elbow—and forced into the crankcase bya new-type rotor pump. The air circulates through-out the crankcase collecting harmful vapors andis then expelled out through a vent ahead ofthe tappet-case cover. The crankcase ventilationsystem is entirely automatic and goes a long waytoward keeping the engine clean and providinglonger, more dependable service.
