Description
The winch is intended for towing of cut-down timber from the forest and timber ramping. It is
constructed of welded housing, drive mechanism, clutch, drum with wire rope, brake and
diverting pulley. With the help of wire rope, the timber is towed to the ploughing attachment
and attached on the grooves on the winch housing with forestry chains. Then, the timber
can be transported to the place, where other transport means have access.

Three-point hitch of I and II category.
Maximum number of revolutions and direction of tractor PTO shaft rotation is 540 min

PTO SHAFT ADJUSTMENT
Length of PTO shaft needs to be adjusted for different tractors (figure 6). For winch 35M, it is
appropriate to use a PTO shaft, torque max. 355 Nm, type W 200E, for 40eco torque max. 500
Nm, type W 300E Walterscheid.
Ascertain the accurate length in the following manner:
1. Shut down the tractor.
2. Connect the machine to the tractor.
3. Extract the PTO shaft apart and connect the individual shaft halves to the tractor and
machine and compare them crosswise and mark them (figure 8.1).
4. Shorten external and internal plastic protection pipes (figure 8.2).
5. Shorten external and internal slide profiles with the same distance as plastic protection
pipes (figure 8.3).
6. Crop the pipe end, remove fillings and grease the slide positions well (figure 8.4).
