OPERATION
6. SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain. Note: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to contact the ground.
DANGER! Never work under the Implement, the framework, or any lifted compo- nent unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.
6.1 SETTING DECK HEIGHT
LEVELING DECK CENTER SECTION
1.Place the tractor and mower on a level surface and lower both wings.
2.Using the center section hydraulic cylinder, position the mower so the skid shoes are 1” less off the ground than the desired final cut height. For example, for a 3” cut raise or lower the mower until the skid shoes are approximately 2” off the ground..
3.Shut down the tractor, place the transmission in park, and set the parking brake before dismounting.
4.Level the mower deck front to rear by adjusting the leveling rods linking the tongue to the rear axle. DO NOT allow feet or other body part underneath the mower when making adjustments. To adjust rod length, loosen jamnut and screw turnbuckles. To lower the front, lengthen the rods and to raise the front, shorten the rods. DO NOT unscrew turnbuckles to the point that either rod threaded ends becomes disconnected which will cause the mower to fall.
IMPORTANT: Alternate adjustments between rods and adjust at equal lengths to maintain equal tension. Improper adjustments may cause rods to snap or bend.
5.Place split collar assemblies on the center axle hydraulic cylinder rod to maintain a set cutting height each time the mower is raised and lowered.
