Farmi Logging Winch for Skid Steer Loaders
The Farmi Tree Harvesting Method
Farmi SSGR50 Skid-Steer Grapple
A skidding grapple is your best choice of machine if you work on flat terrain which is dry, and you have a large tractor with sufficient front-end weights. For front end weight requirements, click here. Skidding grapples work best in clear-cuts. If you are working in hilly, wet, or slippery terrain, or if you want to reduce damage to the stand by selective cutting, there is equipment that will work better than a skidding grapple.
Valby Tractor Grapple Model SGR 76
The Valby grapple converts your farm tractor to a productive forest machine. It can be used for skidding out stems from the woodlot to the landing. The grapple has hydraulic control for shifting the grapple sideways, which enables it to also be used for stacking. The grapple is 3-point hitch mounted, and has a parking stand, so it is easy to hook up to the tractor. The design of the grapple enables it to be used for multiple full-length stems. If used on short wood, such as 8 foot pulp, one can lift up the pile and transport it without touching the ground, keeping the wood clean.

The Valby SGR 76 has a hydraulic side shift,
which enables it to be used for stacking.

The grapple opens to 76 inches and has a side-shift feature. The hydraulic side-shift enables the operator to grab a load from the side without spending time to maneuver the tractor. The side-shift also helps the operator to stack the logs in piles at the landing. The grapple cylinder and the side-shift cylinder are of welded design and built for up to 2900 psi of pressure. The grapple cylinder and the side shift cylinder are double-acting and thus require two sets of hydraulic outlets from the tractor. One set is to open and close the grapple, the other set is to turn the frame. It would be advantageous if the tractor has a floating position on the circuit which runs the side shift. The tractor must be equipped with front end weights.
