ATTACHING KIT INSTRUCTIONS (For 665H & 765H)

3-POINT HITCH LINKAGE & HYDRAULIC HOOK-UP

TO TRACTOR HYDRAULIC SYSTEMS

General Description

Mounting and hydraulics kits include two hoses which can be used to connect the backhoe to the tractor hydraulic system. Additional hydraulic components or kits will be required to complete the hook-up to the tractor hydraulic system. Refer to the Hydraulic Hook- up section for further information. Pumps and reser- voir kits are available as options.

The backhoe is mounted on the tractor lower link arms and an adjustable upper link is supplied to replace the tractor upper link. A set of stabilizer arms is included. They bolt from the adjustable upper link to the backhoe mainframe, locking the hoe rigidly in one position.

IMPORTANT: Tractor lower links must be kept free of lifting forces at all times after installation of the attaching kit, by keeping tractor quadrant lever in the lowered position.

IMPORTANT: If the 3-Point Kit is to be used with a PTO & Reservoir Kit, the Reservoir Tank and it’s fit- tings should be installed before proceeding with the 3-Point installation.
