Operating Tips • For the best performance, operate the engine at the maximum speed. The mower requires air to thoroughly cut grass clippings, so do not set the height-of-cut too low or completely surround the mower in uncut grass. Always leave one side of the mower free from uncut grass to allow the air to be drawn into the mower. • Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. When cutting grass longer than 6 in.
Maintenance Note: Determine the left and right sides of the tractor from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval After first 20 hours Each use Maintenance Procedure • Check the blade drive belt adjustment. • • • • • • • Check the oil level. Check the safety system. Clean the mower housing. Check the battery electrolyte level. Check the tire pressure. Check the blades. Check the brakes. Every 25 hours • Grease the chassis.
