Features and Controls Features and Controls A. S/N: 2014582798 & Below B. S/N: 2014582799 & Above B N o R tf ep o r ro du ct io n A Control Functions The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section.
Features and Controls (S/N: 2015276815 & Above): The ignition switch starts and stops the engine, it has three positions: OFF Stops the engine and shuts off the electrical system. HEAT/ RUN Turning the key to this position prior to starting the engine heats the glow plugs. After the engine starts the ignition returns to this position and allows the engine to run and powers the electrical system. START Cranks the engine for starting.
Operation Operation WARNING General Operating Safety Before first time operation: • Be sure to read all information in the Safety and Operation sections before attempting to operate this tractor and mower. • Become familiar with all of the controls and how to stop the unit. • Drive in an open area without mowing to become accustomed to the unit. Do not use this machine on slopes greater than 15 degrees. Select slow ground speed before driving onto a slope.
Operation Priming the Fuel System B Priming the fuel system removes any air bubbles from the fuel system. WARNING Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the ignition switch off when changing fuel filter or water separator element. Clean up fuel spills immediately. The fuel system would only need to be primed under the following conditions: • Before starting the engine for the first time.
Operation If you do not understand how a specific control functions, or have not yet thoroughly read the FEATURES & CONTROLS section, do so now. Do NOT attempt to operate the tractor without first becoming familiar with the location and function of ALL controls. Starting the Engine 1. While sitting in the operators seat, engage the parking brake, make sure the PTO switch is disengaged, and the ground speed control levers are locked in the neutral position. 2.
Operation Zero-Turn Driving Practice Smooth Travel The lever controls of the Zero Turn rider are responsive. Learning how to gain smooth, efficient control of the rider’s forward, reverse, and turning movements will take some practice. The lever controls of the Zero Turn rider are responsive. Locate a smooth, flat area of your lawn — one with plenty of room to maneuver. (Clear the area of objects, people and animals before you begin.
Operation Practice Turning Around a Corner Practice Turning In Place While traveling forward allow one handle to gradually return back toward neutral. Repeat several times. To turn in place, “Zero Turn,” gradually move one ground speed control lever forward from neutral and the other lever back from neutral simultaneously. Repeat several times. NOTE: To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.
Operation Mowing 1. Engage the parking brake. Make sure the PTO switch is disengaged, the motion control levers are locked in the NEUTRAL position, and the operator is on the seat. 2. Start the engine (see STARTING THE ENGINE). 3. Set the mower cutting height. 4. Set the throttle to FULL. 5. Engage the PTO by pulling up on the PTO switch. 6. Begin mowing. 7. When finished, shut off the PTO. 8. Stop the engine (see STOPPING THE TRACTOR AND ENGINE).
Operation When and How Often to Mow The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines: 1. Mow when the grass is between three and five inches high. 2. Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass. 3. Mow at time of day when the grass is cool and dry.
Operation Proper Mulching Attaching a Trailer Mulching consists of a mower deck which cuts and recuts clippings into tiny particles and then blows them down INTO the lawn. These tiny particles decompose rapidly into by-products your lawn can use. UNDER PROPER CONDITIONS, your mulching mower will virtually eliminate noticeable clippings on the lawn surface. The maximum weight of a towed trailer should be less than 200 lbs (91kg).
Operation Raise & Lower the Roll Bar To lower the roll bar: C 1. Pull the hair pin clips (A, Figure 11) out of the retainer pins (B). 2. Push or pull the top of the roll bar (C) forward against the rubber stops (D) and remove the retainer pins (B). 3. Lower the roll bar and reinstall the retainer pins and hair pin clips to secure the roll bar in the down position (see insert, Figure 11). D C To raise the roll bar: B D Figure 11. Raise & Lower the Roll Bar A. Hair Pin Clip B. Retainer Pin C.
Operation Storage Remember, the fuel tank will still contain some fuel, so never store the unit indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the unit in any structure used for human or animal habitation. Here is a checklist of things to do when storing your unit temporarily or in between uses: • Keep the unit in an area away from where children may come into contact with it.
