manual for recommended oil type and viscosity.
Lubricate all grease fittings. Refer to the grease schedule in this manual.
Check that all nuts and bolts are in place and properly tightened. Refer to the 'Maintenance' section of this

Connection to Tractor
Pin the hitch jack to the stub on the mower hitch frame and raise the hitch clevis to line up with the tractor
drawbar. A screw driver may be inserted into the hole in the side of the swivel hitch to keep the hitch clevis
level while connecting to the tractor drawbar.
Connect the hydraulic hose to the remote outlets on the tractor. The V1280 requires two double acting
hydraulic circuits, one for operation of the center frame lift system and one for operation of the wing lift system.
The cylinder should be cycled several times to remove air from the system.
