DRIVELINE INTERFERENCE CHECK
1.Check for clearance between driveline and cutter deck.
2.Slowly lift cutter and observe driveline. If clearance between driveline and cutter deck is less than 1 inch, shorten top link or limit upper travel of lower hitch arms. Refer to tractor operator's manual for instructions.
CUTTING HEIGHT ADJUSTMENT
Before working underneath, disconnect drive- line, raise cutter, lock in transport position, and block cutter securely. Hydraulic system leak down and failure of mechanical or hydraulic system can cause equipment to drop.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
■Avoid low cutting heights. Striking the ground with blades produces one of the most damaging shock loads a cutter can encounter. Allowing blades to contact ground repeatedly will cause damage to cutter and drive.
When selecting a cutting height, you should consider the area of operation. If the ground is rolling and has mounds the blades could contact, set the cutting height accordingly.
1.Level cutter from side to side. Check by measuring from cutter frame to the ground at each deck rail.
2.Adjust, using tractor
NOTE: Keep the front of cutter level with or slightly lower than rear for best mowing.
3.Control cutting height with tractor
4.To raise rear of cutter, move tailwheel down.
5.To raise front of cutter, raise tractor
The cutting height is the distance between the blade and the ground. The blades are approxi- mately 11.5" below the deck. To check cutting height, do the following:
a)Place a straight edge along top edge of deck.
b)Select a cutting height; as an example, for an approximate cutting height of 3", set the center of the deck 14.5" above the ground:
3" Desired cutting height
+11.5" Distance blade cutting edge is below deck
=14.5"
c)Adjust the
CHECK CHAIN ADJUSTMENT
1.Refer to Check Chain Installation (Optional), page 33 for check chain installation.
2.After making cutting height adjustment, adjust both chains (3) in check chain bracket (2) so you have the same number of links on each side. This will keep your cutting level.
2.Check chain bracket
