G008962 Figure 34 Unlatching the Seat Figure 32 Note: Certain models will have a fixed seat and cannot be rotated up. Position C This is the full open position. The suggested use for this position is as follows. • Use in tall, dense grass mowing conditions. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower. Figure 35 1. Seat latch 2.
Note: Make sure the release valves are in the fully horizontal position when operating the machine or severe damage to the hydraulic system can occur. DANGER Without a grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. 1. Disengage the PTO (blade control switch) and turn the ignition key to off.
Loading Machines Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit (Figure 38). The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward.
Operating Tips WARNING Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the fast throttle position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass.
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, move onto a previously cut area with the blades engaged.
