SGR76 Conpact Tractor Grapple with Hydraulic Side Shift


Bypass Tractor Grapple

The modern bypass tractor grapple is an improvement over clamp grapples. The Valby tractor grapple is unique in that it has a double jaw on one side, and a single jaw on the other. As the grapple closes, the double jaw inter-meshes with the single jaw. The form of the bypass grapple provides for easy "roll in" of the logs. The logs are then held firmly in place because the load is supported from all directions by the bypass jaws. This Tractor Grapple is recommended for tractors 50hp and up.

The Valby SGR76 Grapple converts your farm tractor into a productive forest machine. It can be used three ways:


The skidding grapple is your best choice machine if you work on flat terrain, which is dry, and you have a large tractor with sufficient front end weights. The ruggedness of the grapple enables multiple tree length stems to be skidded out at one time.

Transport of Small Stems

Small stems, stacks of pulp wood, brush, and slabs can be lifted clear off the ground. This keeps the material clean, and transfers the weight of the material to the rear tires, for added traction.


The side-shift function enables easy placement of the material in stacks. The high of the stacks depends on the tractor, but four to five foot stacking heights are typical.

Heel Bar

The photo above shows how the heel bar enables light logs to be lifted off the ground. The heel bar also prevents skidded logs from being hung up on the frame when turning


The Valby SGR76 can be side-shifted 30 degrees to either side, as shown in the photo below. Side shifting allows the operator to grab loads from the side, without spending time maneuvering the tractor. The side shifting also allows for controlled stacking of pulpwood and similar materials.

Frame Hinge

The Valby tractor grapple has a hinge next to the three point hitch frame. The hinge enable tight turning and improves the maneuverability of the tractor.

Mechanical Frame Lock

If your tractor does not have two sets of remote outlets, or a floating position, you can choose the SGR76-ML model, which requires only one set of hydraulic outlets.

This version does not have a side shift cylinder, but has a frame lock that locks the grapple in place when needed. When the frame is in a floating position, it provides a hinge point and enables the tractor to make turns. The frame lock is rope controlled from the tractor cab.

Head Board Plate

The head board plate enables the grapple to bunch logs and piles. It also prevent logs from coming in contact and damaging the tractor.

Durable Design

The grapple is designed to endure years of professional use. The materials used are thick, and the jaws are boxed for added strength.

Both cylinders of the grapple are welded design, and have an inside diameter of over 3". That provides strong holding pressure for the jaws that hold onto the logs. The cylinders can take pressure of up to 2900 PSI. The piston is also over-dimentioned, and has a diameter of almost two inches.

Every joint has a grease fitting, and the unit weighs 790lbs. The head-board plate can be used to bunch the logs into piles suitable for transport by the tractor grapple. The jaws are made to withstand hard use, and the pins have large diameters.


The grapple mounts on the three point hitch of any category II tractor between 50 and 100 HP. The tractor must be equipped with a full set of front end weights. The grapple has a parking stand, which enables easy hook up and removal of the machine.

The grapple needs two pairs of hydraulic outlets off the tractor. One pair opens and closes the grapple. The other pair works the side shift. If the hydraulic side shift is not important to you, or if your tractor does not have a second hydraulic circuit, you can still choose a Valby grapple by selecting a version that has a mechanical lock of the frame instead of the cylinder.

If the grapple is used for skidding, when the ends of the stems drag on the ground, then one will benefit from having a floating position on the valve that operates the side-shift. Your dealer can retrofit older tractors with a valve that has a float position.

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.

If your tractor has extra hydraulic outlets, one can also use the grapple with a hydraulic top link.
