Operation Side Discharge Operation The mower has a hinged discharge chute that disperses clippings to the side and down toward the turf. While the ignition key is in RUN or LIGHTS position and the power take off (PTO) is engaged, the PTO indicator light will be on. When this light is ON, it is a reminder: the implement is being powered and the starter will not crank while the PTO is engaged. Always turn off the PTO before getting off the seat.
Operation Attachment Lift Lever 1 The attachment lift lever (Fig. 25 & 26) is used to raise and lower various attachments. Raising Attachments 1. Start the tractor. 2. Pull the attachment lift lever upward until the latch locks. In this position, the lift will hold the attachment in the up, or raised position. m--3258 Figure 25 POTENTIAL HAZARD · When the engine is off, attachments in the raised position can gradually lower. 1.
Operation Adjusting the Center Roller Adjusting the Front Wheels The center roller guides the mower over uneven turf without scalping the lawn. For most cutting conditions it should be located in the lower hole. When cutting in 1 1/2” height-of-cut, move the center roller to the upper hole position. The two front adjustable wheels must be adjusted in the proper hole location for each time you change deck height-of-cut position. 1. Raise the attachment lift lever; refer to Raising Attachments. 2.
Operation Check for Debris Cut 1/3 of the Grass Blade Each time you use the mower, be sure to check for debris build up on and inside the rear transaxle cover (Fig. 29). Remove any build up. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended, unless grass is sparse or it is late fall when grass grows more slowly. Mowing Direction Alternate mowing direction to keep the grass standing straight.
Operation Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. When Stopping If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this: 1. With the blade(s) “ENGAGED,” move onto a previously cut area. 2.
