Valby Tractor Grapple Model SGR 76-ML
With mechanical frame lock.
Mechanical Frame Lock
The SGR76-ML is used on tractors that do not have two sets of remote outlets, or do not have a floating position.
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.
Bypass Tractor Grapples:
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.
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:
The Valby tractor grapple has a heal bar so 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 grapple is designed to endure years of professional use. The materials used are thick, and the jaws are boxed for added strength.
The cylinder on the grapple is of a welded design, and has an inside diameter of over 3". That provides strong holding pressure for the jaws that hold onto the logs. The cylinder can take pressures of up to 2900 PSI. The piston is also over-dimensioned, and has a diameter of almost two inches.
Every joint has a grease fitting, and the unit weighs 740lbs. 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.
One design feature that makes the Valby SGR76 tractor grapples easy to use is that they have a hinge point close to the tractor. This forward hinge point enables the tractor to make sharp turns.
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.

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.

The SGR76-ML comes with the brackets for the hydraulic side shift cylinder. This enables you to retrofit the grapple if you find a need for the side shift feature.
If your tractor has extra hydraulic outlets, one can also use the grapple with a hydraulic top link.
The forward hinge point of the SGR76-ML tractor grapple enables the operator to make sharp turns with the tractor.
