Loading the Machine Important Do not rotate the by-pass valves more than 1 turn. This prevents the valves from coming out of the body and causing fluid to run out. 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. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward.
Using a Rollover Protection System 1 Rollover protection systems (ROPS) are available for many riding machines. Contact an Authorized Service Dealer for information on obtaining ROPS for your machine. 3 2 Using the Z Stand m–5600 Figure 25 The Z Stand is used for raising the front end of the machine. This allows for cleaning of the deck and removal of the blades. 1. Z Stand (positioned in slot) Warning 2. Crack in side walk or turf 3. Latch resting on pivot tab 3. Raise the latch.
in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting. 4. Return the stand to its rest position (Fig. 24). 4 3 Cutting Speed 2 To improve cut quality, use a slower ground speed in certain conditions. 1 Avoid Cutting Too Low If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
