A winch is a machine intended for harvesting felled timber from the forest. The basic components are welded frame, drive part, drum with wire rope, clutch, brake, and directional pulley. Using the wire rope, the logs can be towed to the moldboard and attached with forestry chains to the grooves on the winch frame. Then the logs can be transported to a place which is accessible by other means of transport.

REQUIRED EQUIPMENT OF THE TRACTOR

-PTO shaft with chosen gear ratio, max. 540 RPM.

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

PTO SHAFT ADJUSTMENT

Length of PTO shaft needs to be adjusted for different tractors . 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.

4. Shorten external and internal plastic protection pipes .

5. Shorten external and internal slide profiles with the same distance as plastic protection pipes (figure F3).

6. Crop the pipe end, remove fillings and grease the slide positions well.

TRACTOR MOUNTING

When connecting the winch, do not stand in the danger zone!

The forestry winch can be attached to every tractor with a three-point hitch with a category I coupling. Appropriate construction also enables easy connection to the tractor with automatic connection rods. Connect the prescribed PTO shaft and secure cardan protection with a hang chain.

Be careful that the cardan clicks into place on both connection points!

Once the winch is attached to the tractor, strengthen the stabilizers on the lower connection rods and level the winch with a hitch nut into position, so that the winch is tilted backwards for approximately 20 degrees.

WIRE ROPE UNWINDING

Steel rope must be completely unwound before first use and wind it back on the generator drum under load.

For instance, we can do this so that we attach the rope to a standing tree and pull the tractor with slight braking to the tree. This procedure must be done also before trying to tow, if we towed downhill beforehand or if the rope was wound loosely during towing.
