Woods Equipment MD80-2 Cutting Height Adjustment for D80 Pull- Type Cutter, Operating Technique

Connect cutter driveline to tractor PTO shaft, making sure the spring-activated locking pin slides freely and is seated firmly in tractor PTO spline groove.

Adjust H-frame bearing height to ensure front driveline is parallel to ground.

Remove parking jack from tongue. Attach to frame rail storage with top forward. Always attach jack to tongue to hold it up when disconnecting it from tractor.

Adjust drive shaft carrier bearing (2), Figure 6, verti- cally in H-frame until driveline is as straight as possible between tractor PTO and cutter gearbox.

Cutting Height Adjustment for D80 Pull- Type Cutter

Place tractor and cutter on a level surface.

Cutting height is raised and lowered with height adjust- ment crank (3) or optional hydraulic cylinder. Front to rear attitude is set with the compression link (1). See Figure 6.

The blade is approximately 9-1/4" below cutter deck.

Select a cutting height, EXAMPLE 3".

Raise front end of deck with a jack to take the compres- sion member (1) out of compression and remove the bolt connecting it to the tongue.

Raise front end of deck until both sides are 12-1/4" above the ground and block underneath to maintain this distance.

Raise rear end of deck until it is from 13-3/4" to 14" above the ground.

Connect compression member (1) to tongue. It may be necessary to raise or lower rear of deck to align hole.

Remove the blocks from under the deck and position each side skid 1/2" above the ground.

This complete procedure must be followed to properly set a new cutting height. Raising rear of deck with crank without changing the compression link position will result in an incorrect front-to-rear attitude setting.

PRE-OPERATION CHECK LIST

(Owner’s Responsibility)

___ Check that cutter is properly and securely attached to tractor.

___ Make sure driveline spring-activated locking pin slides freely and is seated firmly in tractor PTO spline groove.

___ On pull-type cutter, make sure the pin to prevent crank detachment is installed.

___ Set tractor PTO at 540 rpm.

___ Make sure gearbox is full to fill plug with SAE 90W gear lube.

___ Lubricate all grease fitting locations.

___ Check that all hardware is properly installed and secured.

___ Check to ensure blades are sharp and secure and cutting edge is positioned to lead in a counter-clockwise rotation.

___ Check that all shields and guards are properly installed and in good condition.

___ Check cutting height and attitude adjustment.

___ Place tractor PTO and transmission in neutral before attempting to start engine.

___ Inspect area to be cut and remove stones, branches or other hard objects that might be thrown, causing injury or damage.

___ Inspect chain shielding and replace any damaged or missing links.

STARTING AND STOPPING CUTTER

Cutter operating power is supplied from tractor PTO. Refer to your tractor manual for PTO engagement and disengagement instructions. Always operate PTO at 540 rpm. Know how to stop tractor and cutter quickly in case of an emergency.

When engaging PTO, the engine rpm should always be low. Once engaged and ready to start cutting, raise PTO speed to 540 rpm and maintain throughout cutting operation.

OPERATING TECHNIQUE

Proper ground speed will depend upon the height, type and density of material to be cut.

Normally, ground speed will range from 2 to 5 mph. Tall dense material should be cut at a low speed, while thin medium-height material can be cut at a higher ground speed.

Always operate PTO at 540 rpm; this is necessary to maintain proper blade speed and produce a clean cut.
