Stump cutters

TractorHydraulicEngine

Established by Henning Schmidt in 2002, FSI power-tech ApS

develops and manufactures stump cutters. This has been the

company’s key competency since its foundation, and it has

built up extensive know-how and expertise in the mechanical

challenges involved in cutting tree stumps.

From its factory in Ølholm near Tørring in central Jutland, the

company services all of its customers and dealers in Denmark,

and importers from a large number of countries in Europe. The

company also exports to other countries around the world,

including America, Australia and New Zealand.

FSI stump cutters are aimed at professional users, who

are primarily landscape gardeners, tree felling companies,

developers, hire companies, municipalities, housing

associations and similar companies with activities in the green

sector.

FSI ensures the high quality of all of its products by carrying out

quality assurance and testing on all of its stump cutters before

they are shipped.

We want every customer who uses an FSI stump cutter to be fully satisfied with its performance

FSI power-tech ApS

The FSI range of stump cutters consists of three groups of machines, defined by their power source.

TRIPLEX Teeth System

Every FSI stump cutter is equipped with TRIPLEX cutting teeth. The teeth are round and during operation the wearing surface covers about 120 degrees, so the teeth can be rotated three times before they have to be replaced. The teeth are secured using a single nut.

The teeth are fitted in holders made from durable cast steel. The holders are fixed on the cutter wheel so that adjustments are not necessary when replacing teeth or holders. For increased capacity, the holders are fitted in a staggered system on the disc, so that each tooth cuts its own track.

Tree stump cutting times

In collaboration with some of our customers, we have devised an overview of the time taken to cut up three different diameters of tree stumps. The figures are based on the cutting of a tree stump that is 15 cm high and which extends for 15 cm below the ground.

The times stated in the table can vary depending on the tree species, the age of the stump, the machine operator and the power of the actual tool carrier.

Towable stump cutter with petrol engine

B20 is a compact and balanced stump cutter that can be used to cut up all types of tree stumps.

The pivot joint between the stump cutter and the chassis ensures easy and smooth cutting, even under difficult conditions.

The brakes can be applied individually to each wheel, so the machine can easily access the stump even if there are shavings in

the way. The individual brakes can also be used to negotiate steps with ease.

Extra equipment

Drawbar for ball and socket coupling, for transport up to 10 km/h. Not permitted on public roads.

Hour counter with alarm for every 25 hours for lubrication and for every 100 hours for oil change. Can be retrofitted.

B22Engine

Stump cutter with 2WD and petrol engine

FSI B22 is a new stump cutter that combines the many areas of application of the B20 but which is also self-propelled, so that moving over uneven terrain is much easier, and especially when loading or unloading from a trailer. Hydraulic wheel drive, speed and forward/reverse are controlled from the handlebar. A free-running feature ensures that the machine can be moved without having to start the engine.

A swivel joint between the stump cutter and the chassis ensures an easy and smooth swing movement for the stump cutter, without the wheels having to be moved. This ensures fast and efficient stump cutting, even on inclined or uneven surfaces.

D30 TRACK: Stump cutters on tracks with diesel motor

FSI D30 TRACK is the well-known D30 stump cutter which is equipped with tracks instead of wheels. It is aimed at serious users who often work in very inaccessible terrain. The diesel engine pro-vides high performance capacity and excellent operating efficiency.

All machine operation is executed via the rotatable control panel, so the operator can stand behind the machine during operation and move towards the work site, and the control panel can be turned during stump cutting, providing a good overview of the stump during the stump cutting process. The speed of swing movement can also be controlled from the control panel.

D74 REMOTEEngine

Stump cutter with remote control, 4WD and diesel engine

FSI D74 for the professional use where stump cutting forms a major part of their daily work.

The powerful 74 HP diesel engine with an impressive torque of 300 Nm at 1500 rpm, the large 720 mm cutter wheel and a working width of 2 m means this machine has incredible capacity. Together with the 4-wheel drive and radio remote control, the D74 Remote is your ideal partner for cutting tree stumps.

All movement and stump cutting operations are controlled via the

radio remote control. A battery charger with a spare battery for the radio control system is mounted on the machine. Includes a cable to connect directly to the remote control.

The machine is also equipped with an autopilot swing function for optimum cutting capacity. The autopilot adjusts the swing speed based on the engine load. The autopilot optimises capacity and makes it simpler to operate the machine.
