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 pri-marily 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 SystemEvery 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 fitted 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.

Power clutchPower clutch, the clutch between the engine and the cutter wheel is a strong and unique hydraulic clutch with integrated brake. The clutch engages smoothly and efficiently, with 4 x cylinders and when the clutch is disengaged, the brake activates automatically.

Tree stump cutting timesIn 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 engineB20 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 equipmentDrawbar 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.

Special colour instead of the original FSI red. Extra delivery time shall be expected.

B22Engine

Stump cutter with 2WD and petrol engineFSI 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.

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