Hydraulic Connection
1.Inspect hydraulic hoses to ensure they are in good condition.
2.Clean the fittings before connecting them to the tractor hydraulic ports.
3.Route the hose through the hose holder at the hitch and be sure the hose can slide freely in the holder. Do not allow hose slack to drag on the ground or become caught on tractor protrusions.
4.Attach the hydraulic hose to the tractor.
5.From the operator position, start tractor and raise and lower deck several times to purge trapped air from the hydraulic cylinder.
Interference Check
1.Be sure that tractor
2.Check for
3.Contact between tractor lift links and cutter parts can cause damage, especially when turning.
CV Driveline Turning Limits
NOTICE
■You must not exceed a turning angle of 80 degrees at the head of the Constant Velocity drive- line or damage will occur.
1.To check for potential excessive turn angle, disconnect the driveline from tractor.
2.Start engine and turn as far right or left as possible.
3.Shut engine off and try to connect CV driveline to tractor. If it cannot be connected, the turn angle is too severe.
4.Restart engine and straighten angle slightly, shut off engine and try to connect CV driveline to tractor.
5.Repeat the process until the driveline can be connected. The point at which the driveline can be connected is the maximum turn that should be made.
Cutting Height Adjustment
NOTICE
■Avoid ground contact with blades. Striking ground with blades produces one of the most dam- aging shock loads a cutter can encounter. If this occurs repeatedly, the cutter, driveline, and gear- boxes will be damaged.
On
Cutting height range is from 2" to 15". A hydraulic cylin- der or ratchet jack is available for cutting height adjust- ment.
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. The cutting height (blade edge) is approxi- mately 1" above the bottom of the side skid.
Cutting Height (Normal Mowing) - Center Section
1.Position the cutter on a hard level surface and select an approximate cutting height, Example 6".
2.Raise wings and lock them in the UP position.
3.Use the hydraulic cylinder or ratchet jack to raise or lower the center section to obtain a distance of 5" from bottom edge of skid shoe to the ground.
4.Place jackstands under the four corners of the center section. See illustration on page 20. Lower center section to relieve pressure on attitude rod nuts.
5.Loosen outer jam nut on the attitude rods.
6.Adjust inner nuts in or out until the rear of the cutter is approximately 1/2" higher than the front. See Figure 1A. It’s used as a starting point for adjusting the attitude rod, based on different tongue height and wheel options.
7.Raise cutter, remove jackstands and check deck height. Tighten jam nuts against sleeve.
