1. Clean the reservoir cap and the area around the cap to prevent debris from contaminating the transmission oil. See Figure 4-6. Figure 4-6 2. Turn the reservoir cap counter-clockwise to remove, then check the oil level in the reservoir. Oil should be visible at the bottom of the cup, but the oil level must NOT be above the "FULL COLD" line. See Figure 4-6. DO NOT FILL THE RESERVOIR. 3. If necessary to add oil because of some type of leakage, use a quality 20W50 motor oil and add only enough oil to bring the level to the "FULL COLD" line. Reinstall the cap and fully tighten. NOTE: Prior to the initial operation of the tractor, the oil level in the reservoir may be slightly higher than the maximum due to air in the oil lines. Operation of the tractor will eventually purge the air from the lines and the oil level will settle to the maximum. Tractor Storage If your tractor is not going to be operated for an extended period of time (30 days to approximately six months), the tractor should be prepared for storage. Store the tractor in a dry and protected location. If stored outside, cover the tractor (including the tires) to protect it from the elements. The procedures outlined below should be performed whenever the tractor is placed in storage. 1. Change the engine oil and filter following the instructions provided in the engine manual packed with this manual. WARNING! Never store the tractor with fuel in the tank indoors or in poorly ventilated enclosures, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, etc. 2. If storing the tractor for 30 days or more: a. To prevent gum deposits from forming inside the engine's carburetor and causing possible malfunction of the engine, the fuel system must be either completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration. WARNING! Fuel left in the fuel tank deteriorates and will cause serious starting problems. 20 Section 4- Service b. Use a fuel stabilizer for storage between 30 and 90 days: • Read the product manufacturer's instructions and recommendations. • Add to clean, fresh gasoline the correct amount of stabilizer for the capacity (approximately 3 gallons) of the fuel system. • Fill the fuel tank with treated fuel and run the engine for 2-3 minutes to get stabilized fuel into the carburetor. c. Emptying the fuel system for storage of more than 90 days: • Prior to putting the tractor in storage, monitor fuel consumption with the goal of running the fuel tank empty. • Run the engine until it begins to stall. Use the choke to keep the engine running until all fuel in the carburetor has been exhausted. • Referring to the engine manual, drain the fuel from the carburetor bowl. 3. Clean the engine and the entire tractor thoroughly. 4. Fully charge the battery, then disconnect the negative cable at the battery to prevent possible discharge. Recharge the battery periodically when in storage. NOTE: Remove the battery if exposed to prolonged periods of sub-freezing temperatures. Store in a cool, dry location where temperatures are above freezing. 5. Lubricate all lubrication points. NOTE: Using a pressure washer or garden hose is not recommended for cleaning your tractor. It may cause damage to electrical components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability. Removing The Tractor From Storage 1. Check the engine oil. 2. Fully charge the battery and inflate the tires to the recommended pressure. 3. Fill the fuel tank with clean, fresh gasoline. 4. Start the engine and allow to idle for a few minutes to ensure engine is operating properly. 5. Drive the tractor without a load to make certain all the tractor systems are functioning properly. Adjustments WARNING! Shut the engine off, remove the ignition key and engage the parking brake before making adjustments. Protect your hands by using heavy gloves when handling the blades. Deck Leveling NOTE: Check the tractor's tire pressure before performing any deck leveling adjustments. Refer to Tires for information regarding tire pressure. Leveling the Deck (Side-to-Side) NOTE: Check the tractor's tire pressure before performing any deck leveling adjustments. Refer to Tires for information regarding tire pressure. Always level the deck side-to-side before front to rear. If the cutting deck appears to be mowing unevenly, a side-to-side adjustment can be performed. Adjust if necessary as follows: 1. With the tractor parked on a firm, level surface, place the deck lift handle in a middle mowing position and rotate both outside blades so that they are perpendicular with the tractor. 2. Measure the distance from the outside of the left blade tip to the ground and the distance from the outside of the right blade tip to the ground. Both measurements taken should be equal. If they're not, proceed to the next step. 3. Loosen the lower nut (a) on the adjustable lift link (b) attached to the deck lift arm (c) to lower the deck and tighten the upper nut (d) to secure the deck in place, loosen the upper nut (d) then tighten the lower nut (a) to secure the deck in place. See Figure 4-7. (b) (d) (c) (a) Figure 4-7 4. The deck is properly leveled when both blade tip measurements are equal. Leveling the Deck (Front-To-Rear) NOTE: Check the tractor's tire pressure before performing any deck leveling adjustments. Refer to Tires for information regarding tire pressure. Always level the deck side-to-side before front to rear.
