FORWARD The Tank Hydrostatic Zero-Turn Commercial Riding Mower provides superb maneuverability, mid-mount cutting capability for professional landscapers, commercial lawn service companies, professional turf managers and golf course superintendents. The machine incorporates many safety features that should be studied by all operators and maintenance personnel before use. The list of safety precautions should receive particular attention.
GENERAL SAFETY OPERATIONS 5. Keep all safety signs legible and properly installed. 6. Do not check for hydraulic leaks with any part of the body. 7. Do not add fuel to a machine when the engine is running and/or the exhaust system is hot. 8. Keep machine clean and free of debris, grass, leaves, oil, grease, etc. 9. Place lap bars in neutral/start position, set park brake, disengage P.T.O., turn engine off, and remove ignition key before you dismount from machine. 10.
terminals can produce sparks and heat...connections to the terminals must be kept tight, and the terminals and battery surfaces kept clean of acids and corrosion. If batteries are re-charged or “jumped” from external sources, make sure that the connections are made properly and in the correct sequence...connect to the positive terminal of the good battery first, then connect that to the positive terminal of the weak battery.

Never leave the mower unattended without: turning off the blade clutch switch; placing the left and right steering levers in the neutral position; moving the throttle to slow; setting the parking brake; shutting off the engine and taking the key from the ignition switch. Never walk or stand on the discharge side of a mower with the engine running.
8. 9. 10. 11. 12. over....use caution in (or avoid) areas where the ROPS could come in contact with any structures, trees, etc. The ROPS and seat belt add additional mass that elevates the machine’s Center of Gravity (C.G.) which negatively affects the machine’s stability and traction....use extra caution when operating on slopes. Inspect the ROPS and seat belt assemblies on a regular basis for damage and improper operation....

of grease, grass, and leaves to reduce the chance of fire and permit proper cooling. Note: If low traction conditions occur, follow these procedures for “zero turns”: To turn clockwise (front of machine moves toward RIGHT) when traveling FORWARD: 1. Come to a stop, 2. Then slowly move both lap bars rearward (no more than 1/2 maximum reverse speed) to initiate REVERSE travel, 3. Then slowly move the LEFT lap bar forward while maintaining the RIGHT lap bar in the rearward travel position. 4.
Steering Levers Foot Pedal Lift Figure. 3 the rear to the front will increase the engine speed from slow to fast. 4. Left and Right Steering Levers: (See Figure 3.) These hinged levers open out to the side in any position to permit the operator to be seated or to leave the mower’s seat. The operator, when seated, can pull the levers up to the operating position, a comfortable forearm’s length away. These levers control all of the movements of the mower.
left or right side of the mower). When the fuel reaches one inch from the top of the tank, stop. DO NOT OVERFILL. Space must be left for expansion. (see page 29 for more specs.) b. Engine Oil: (Filled at the factory before shipment.) Pull out the oil dipstick, wipe it off and reinsert it. Pull it out again and read the oil level. If it is below the operating range, add oil through the fill tube using a funnel to bring it up to the top of the operating range. (see page 29 for more specs.
b. lower the mowing deck into the cutting position. Using a ruler, pencil and paper, measure and note the distance from the paved surface to the bottom edge of the mowing blade at the front and the back of the deck on each side of the mower. (Four dimensions.) 5. Lubricate all fittings listed in the maintenance section. D.
e. This is a one person machine, operator only! Riders are not permitted under any circumstance! f. To start the engine on the machine: 1. Make sure the park brake is set to the “ON” position, both lap bars are in the neutral/ start position, and the Power Take Off (PTO also referred to as blade control switch) is in the “off” (down) position. 2. Move the engine speed control (throttle) forward (half way). 3.
2. To turn clockwise, slowly move the LEFT lap bar forward while simultaneously moving the RIGHT lap bar rearward. Release both lap bars and the machine should stop turning. 3. To turn counter-clockwise, slowly move the RIGHT lap bar forward while simultaneously moving the LEFT lap bar rearward. Release both lap bars and the machine should stop turning (this is a safety check, the normal procedure is for the operator to slowly bring the lap bars to the neutral position). 3. Start the Engine: a.

Medium-lift- These blades require less horsepower than the hi-lift, and they generally work well in wider leaf grasses and some mulch applications.
b. Replace any blade with severe nicks or dents that cannot be removed by filing. c. Check the balance of the blade after sharpening by placing it on a blade balancer. Do not use un-balanced blades. d. If the blade dips on one end, file stock off of the cutting surface on that end. Cover Plate Spindle Note: Blades that cannot be easily balanced—REPLACE. Figure.

They are (1) the blade clutch switch, (2) the steering lever/parking brake switch, (3) the seat switch.They operate so that in order to start the engine, the blade clutch switch must be off, the parking brake must be engaged, and both steering levers must be in the neutral position.
to start the engine. The engine should not start. If it does, the parking brake switch must be repositioned or perhaps replaced. If the engine does not start, engage the parking brake and start the engine. c. Seat Switch: With both steering levers in the neutral position, the parking brake engaged and the blade clutch switch in the “off” position, start the engine. Now release the parking brake, hold down on the back of the operator’s seat against spring pressure.
motors, controlled by the two steering levers. When the mower is parked with the engine shut off, the hydraulic system locks the traction wheels. Note: To move the mower forward or in reverse by pushing, you must release the dynamic braking. Locate the valves on the pump. Turn valves counter-clockwise (using a standard 7/16” wrench) one quarter turn to push the unit.
violent bubbling in the hydraulic oil in the pump. whenever the lap bars are in their Neutral positions. Check the two suction hoses (the hoses connected to the filter) daily before starting the engine. Look for a flattened condition or any leaks and repair or replace as necessary. A flattened or leakng suction hose will permit cavitation to develop which can destroy the pumps in a short time.
G.Cooling System 1. 2. 3. 4. d. Push the mower outdoors and start the engine. Let the engine idle until it has warmed up completely (4 to 5 minutes). The cooling system should be inspected on a regular basis for restrictions to air flow through the heat exchanger core, and for leaks. The heat exchanger core should be cleaned by moderate (50 psi) pressure air or water, but not by brushing. The collant is a 50:50 mixture of de-ionized water and Shell Dex-cool ELA. The total volume is approximately 6.
MAINTENANCE SCHEDULE 7. D. Every 100 Hour Checks A. Daily Checks 1. 1. Before starting engine: a. Check the fuel level.** b. Check the fuel strainer water trap and drain off contaminants if present. c. Check the engine oil level.** d. Check the hydraulic oil level. e. Check the hydraulic hoses for leaks, abrasion, kinks, twists, or a flattened condition. f. Check coolant level in overflow bottle and replenish as necessary. g. Check the tires and tire pressure. Drive Tires: 10-12 psi.
. OIL CHART Apply a few drops of engine oil or use a spray lubricant. Apply the oil to both sides of pivot points. Wipe off any excess. Start engine and operate mower briefly to insure that oil spreads evenly.

C. Deck Corner Ball Wheel Roller Settings 3. 1. Matching the set heights of the ball rollers on the four corners of the mower deck to the desired cut height will prevent edge scalping and minimize any side-to-side variance in cut height. 2. There are three height adjustment holes in the bracket that mount the ball rollers to the deck. a. Use the top set of holes for cut heights of 2 inches or lower. b. c.

This is referred to as blade pitch. The sam height difference should be true for the left blade, measured front and back. 8. To adjust the blade pitch the deck pitch must be adjusted. Loosen the inner jam nuts at the rear of the horizontal threaded rods.
