PRODUCT DESCRIPTION
A winch is a machine intended for harvesting felled timber from the forest. The basic components are welded frame,
driveline, drum with wire rope, directional pulleys, friction clutch and a brake.
In FARMI winches, there are two different kinds of brakes: models W30F, W35R and W50R are operated with
ratchet brake and models W35F, W50B, W60B and W86B with automatically switched on band brake.
There are also two different type of control systems in FARMI winches: 1) Manual control where two ropes are used
by operator to control the unit or 2) electro hydraulic control where operator uses remote control instead of ropes.
In this case, functions are operated with hydraulic cylinders.
Using the wire rope, the logs can be towed to the winch and anchored with chains to the winches slotted dozer plate.
After this logs can be transported to a place where other means of transport are accessible. FARMI winches may
not be used for lifting! Factory setting values may not be changed without a permission of Farmi Forest.

MOUNTING
W30F is a general-purpose winch for all kinds of winching operations. Because the winch has hydraulic function it
may be mounted anywhere provided 2-funtion hydraulic system is available.
In the tractor use it is most appropriate to mount the winch in front where it may stay permanently and at the same
time functions as a front weight.
Mounting in the tractor must be steady, with steel slabs bolted or welded at tractor frame or front weight frame,
provided the front frame is strong enough. The hydraulic winch W30F can also be mounted to the front linkage
using a three-point hitch.
The hydraulic hoses (ø ½”) are attached alongside the tractor frame, well protected from eventuel mechanical
damage.
The coupling nipples should be marked indicating the flow direction in order to avoid rotating the winch motor at
wrong direction.

FASTENING THE CABLE TO THE REEL
Before fastening the cable on the winch, please turn off the tractor and disconnect
the hydraulic line.
WARNING!
1. Tape the cable end to prevent loosening of the core wires.
2. Pass the cable through the hole in cable guard, over the upper diverting pulley and then inside the winch.
3. Insert the cable from behind the roll of the overrun brake.
4. Pull the cable onto the reel from the left hand side (the same side as the clutch lever).
5. Pass the cable end through the hole in the reel plate, pull about 15 cm (6”), and insert under the wedge of the cable
lock device. See fig. 3.
6. Tighten the cable lock screw.
7. Winch the cable on the reel by following spooling instructions.
Fig. 3.
Fastening the cable
Do not use longer cable than needed. With correct length you achieve good pulling strength and proper winding
of the cable.
SPOOLING THE CABLE TO THE REEL
Keep the cable loaded with approx. 100 kg when spooling the cable to the reel (see fig. 4). Keep the cable clamped
to the reel side with using a block of wood, so that first layer spools tightly in order (see fig. 5).

W30F
WINCHING
1. The winch is equipped with a clutch, which will be used by the control rope. When the user draws the control
rope, the winch begins to draw in the cable. Winching will stop when the rope is released.
2. The end of the cable drum is equipped with a friction clutch, which slips, if the load is too heavy. This prevents
cable break or damages if the load gets caught.
3. The cable can be pulled out when the latch is released.
4. Once the latch is released, it will stay released until the operator has engaged it again by pulling on the latch rope.

OPERATION
SAFETY PRECAUTIONS
Read the operation instructions before operating this machine! It is the owner’s
responsibility to instruct all equipment operators and support personnel in the
operation of this winch.
WARNING!
1. Choose a horizontal, hard based skidding route for the tractor. Avoid steep slopes, especially when winching from
the side. Check that the winching trail is clear and that the tractor’s parking brake is on. Do not run the tractor at
a high idle when winching. Maximum P.T.O speed is 540 rpm. Ensure that the logs can be drawn freely. Be
especially careful when working on slopes. Avoid winching sideways at angles exceeding 30 degrees. Use diverting
pulley which is fastened to the tree if needed. (See fig. 9.)
2. The safest place for the operator is at the back left side of the winch, allowing good visibility (See fig. 7). Take care
that there is no one in the working area.
3. The tractor must have a ROPS cab and rear end weights.
a. Always position the tractor on a flat ground in line with the direction of the pull (see fig. 7.). Avoid
working in steep terrain. Ensure nothing is blocking the path of trees.
b. Avoid an unnecessarily strong pulls, the tractor may roll over.
c. Adjust the tractors rpm’s according to the conditions.
