Operation In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • Always place gasoline containers on the ground away from your vehicle before filling. Use Unleaded Regular Gasoline suitable for automotive use (85 pump octane minimum).
• Cleans the engine while it runs • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting Operating on wet grass or steep slopes can cause sliding and loss of control. Important: Do not use fuel additives containing methanol or ethanol. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. Add the correct amount of gas stabilizer/conditioner to the gas.
This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Use protective equipment for your eyes, hearing, feet, and head. Figure 9 1. Parking brake – Set/ON 2. Parking brake – Released/OFF Figure 8 1.

page 14. Remember to remove the key from the ignition switch. Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended. Always remove the ignition key and set the parking brake when leaving the machine unattended, even if just for a few minutes. Adjusting the Height-of-Cut The height-of-cut is adjusted from 25 to 125 mm (1 to 5 inch) in 1/4 inch (6 mm) increments by relocating the clevis pin into different hole locations. 1.
Adjusting the Anti-Scalp Rollers 2. Raise the seat and loosen the adjustment bolts (Figure 18). 3. Move the seat to the desired position and tighten the bolts. Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers. 1. Disengage the PTO, move the motion control levers to the neutral locked position and set the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Pushing the Machine by Hand 2 Important: Always push the machine by hand. Never tow the machine because damage may occur. 1 1 To Push the Machine 1. Disengage the blade control switch and move the control levers to the neutral locked position and apply the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Pull the two bypass levers rearward and push them to the outside into the slot to lock them into place. (Figure 20).
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 21). 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 Fast Throttle Setting Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. 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. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
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.
