Fill out Original Purchaser Registration Card and return the card to Gravely. 4. Explain Gravely Limited Warranty Policy. 5.
SAFETY DECALS AND LOCATIONS ALWAYS replace missing or damaged Safety Decals. Refer to Figure 2 for Safety Decal locations. 7 3 6 1 5 4 3 2 OF1626 Figure 2 1. DANGER! TO AVOID SERIOUS INJURY OR DEATH Go up and down slopes, not across. DO NOT operate on slopes over 17°. Read Owner/Operator Manual. OL4450 • If machine stops going uphill, stop blade and back down slowly. OL1801 • Avoid sudden turns. Keep children and others away from unit while operating.
Determine which attachments are needed and can be used safely. Keep people away from unit while operating. OL3292 Shut off engine, remove key, read manual before you adjust or repair unit.

ALWAYS keep hands and feet away from all rotating parts during operation. Rotating parts can cut off body parts. DO NOT operate in reverse unless absolutely necessary. ALWAYS look down and behind before and while backing. ALWAYS keep body and hands away from pin holes or nozzles which eject hydraulic fluid under pressure. Stop and inspect equipment if you strike an object or if there is an unusual vibration. Repair, if necessary, before restarting.
DO NOT transport machine while engine is running. ALWAYS turn off power to attachment and shut off fuel when transporting unit. Keep unit free of debris. Clean up oil or fuel spills. ALWAYS block wheels and know all jack stands are strong and secure and will hold weight of unit during maintenance. Release pressure slowly from components with stored energy. This product is equipped with an internal combustion type engine.

TRANSPORTING UNIT ALWAYS shut off engine, set parking brake, and remove key when transporting unit on a truck or trailer. Tie unit down securely. Do not tie down by linkages, guards, cables or other parts that may be damaged. FOR BEST PERFORMANCE 2. Place seat in the service position (See SERVICE POSITION on page 17). Cut grass when it is dry.
Interval Task Action Check Safety Interlock System Each Use WARNING: Safety interlock system failure and improper operation of unit can result in death or serious injury. Test this system each time the unit is operated. If this system does not function as described, do not operate until repairs are made. See Safety Interlock System on page 12. Check Parking Brake Engage parking brake. Push unit. If unit rolls, adjust parking brake (see PARKING BRAKE ADJUSTMENT on page 21).
SERVICE AND ADJUSTMENTS Gravely Dealers will provide any service which may be required to keep your unit operating at peak efficiency. Should engine service be required, it can be obtained from a Gravely Dealer or the engine manufacturer’s authorized service center. HYDRAULIC FLUID WARNING: HYDRAULIC FLUID can result in severe burns. Fluid in hydraulic system can penetrate skin and result in serious injury or death. Be sure to stop the engine before doing any work on hydraulic parts.
• Blade is bent or broken. 5. Lubricate rubber gasket on new oil filter with clean hydraulic oil. 2. Sharpen mower blade by removing an equal amount of material from each end of mower blade. DO NOT change angle of cutting edge or round the corner of the mower blade. 6. Spin new oil filter onto filter housing until it makes contact. Tighten oil filter another 1/2 turn. 7. Add new oil to the oil tank. It will take about 4 quarts. Use Mobil 1 15W50 synthetic oil for best pump and wheel motor life. 3.
IMPORTANT: DO NOT fast charge. Charging at a higher rate will damage or destroy battery. ONLY use an automatic charger designed for use with your battery. Remove Battery 1. Place seat in the service position (See MAINTENANCE SCHEDULE on page 15). ALWAYS follow information provided on battery by battery manufacturer. Contact battery manufacturer for extensive instructions to charge battery. 2. Disconnect negative (–) cable first, then positive (+) cable (Figure 9). 3. Remove holddown and remove battery.
STEERING CONTROL NEUTRAL ADJUSTMENT Eliminating Excessive Creeping of the Unit (Figure 11) If the steering levers do not line up (match) or the unit has excessive creeping when the steering levers are in neutral, adjust as follows. WARNING: This adjustment requires operating the engine. Use extreme care to avoid contact with moving parts and hot surfaces. Be sure rear of unit is well-supported and secure before starting engine. Adjusting the Steering Levers to Line Up (Match) (Figure 11) 1.
2. Install the spacer, handle, and eccentric spacer in the appropriate height position. Do not tighten the nut holding the eccentric spacer. If tire pressure adjustment does not solve tracking problem, adjust the limiter bolts on the stop bracket (Figure 12). Front bolts adjust forward and rear bolts adjust reverse. Lengthen the limiter bolt (move closer to lever) on side which is too fast. 3. Turn the eccentric spacer until the right and left handles are the same height. Tighten nut.
5. Arrange new mower belt(s) on deck (mower drive belt first). Retighten short mower belt idler pivot bolt. Install belts on sheaves. Put belts onto center sheave last. 4. Turn the return nuts clockwise to decrease the distance or counterclockwise to increase the distance until there is 1/16 to 1/8 in. (1.59 to 3.18 mm) between the return nuts and trunnion. 6. Replace belt covers and return foot board to closed position. 5. Tighten return nuts together.
5 IMPORTANT: Adjust the mechanical lift spring on each side of the unit to the same length. 6 1 • Adjust the eye-bolt to increase the length of the mechanical lift spring which will decrease the amount of force required to lift the mower deck. 2 • Adjust the eye-bolt to decrease the length of the mechanical lift spring which will increase the amount of force required to lift the mower deck. 3 Increased Spring Length = Decreased Force 2 7 8 4 1. 2. 3. 4. Hydro Belt Spring Idler Engine Sheave 5.
1 Leveling the Mower Deck 1 These adjustments should be made on a level surface with the tires inflated to the correct air pressure. Level the mower with the slots where 4 chains fasten to the mower mounting brackets (Figure 22). 1. Shut off engine. Engage parking brake. Remove the ignition key. 2. Raise mower deck to its highest position and place 4.75 in. (12.1 cm) tall blocks at each rear corner and 4.625 in. (11.7 cm) tall blocks at each front corner. 4 3. Lower deck onto the blocks. 4.

SHORT TERM When storing unit for extended periods of time, remove all fuel from tank and carburetor (run dry). Refer to Engine Manual. NEVER spray unit with high pressure water or store unit outdoors. Inspect unit for visible signs of wear, breakage or damage.
TROUBLESHOOTING PROBLEM Engine does not crank. PROBABLE CAUSE CORRECTION 1. PTO engaged. 1. Disengage PTO. 2. Parking brake disengaged. 2. Engage parking brake. 3. Loose or corroded battery cables. 3. Clean and tighten battery cables (see Clean Battery on page 19). 4. Discharged battery. 4. Charge battery (see Charging the Battery on page 19). 5.
