Drive Control Lever Stop Adjustment When the drive control levers are both fully extended forward to the full-speed position and the tractor drifts left or right, the drive control lever stop adjustment can be adjusted to sync the wheel speeds. To perform the adjustment, proceed as follows: 1. Identify the side that the tractor is drifting to and adjust the opposite drive control lever. If the tractor drifts right, adjust the left control lever down (decrease speed) and vice versa. 2. Locate the drive control lever stop adjustment bolts (a) on the front of the seat frame. See Figure 4-12. (a) Figure 4-12 3. To decrease the forward speed, turn the drive control lever stop adjustment bolts (a) clockwise. To increase the forward speed, turn the drive control lever stop adjustment bolts (a) counter-clockwise. Turn the bolt in the necessary direction 1⁄4-turn at a time. After turning the drive control lever stop adjustment bolts (a), check the adjustment by driving the tractor. 4. Continue the adjustment until the wheel speeds are in sync and the tractor drives straight with the drive control levers fully extended forward in the full-speed position. Off-Season Storage Riding Mower Storage If your riding mower is not going to be operated for an extended period of time (30 days to approximately six months), the riding mower should be prepared for storage. Store the riding mower in a dry and protected location. If stored outside, cover the riding mower (including the tires) to protect it from the elements. The procedures outlined below should be performed whenever the riding mower is placed in storage. 1. Change the engine oil and filter following the instructions provided in the Engine Operator's Manual. WARNING! Never store the riding mower 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. Service the engine as instructed in the separate Engine Operator's Manual. 22 Section 4- Service 3. Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer and engines stored over 90 days need to be drained of fuel to prevent deterioration and gum from forming in fuel system or on essential carburetor parts. If the gasoline in your engine deteriorates during storage, you may need to have the carburetor, and other fuel system components, serviced or replaced. WARNING: Drain fuel only into unapproved container outdoors, away from an open flame. Allow engine to cool. Extinguish cigarettes, cigars, pipes, and other sources of ignition prior to draining fuel. 3. Remove the spark plugs and pour approximately one ounce of oil into each cylinder. Crank the engine one or two turns to spread the oil evenly on the cylinder walls. Replace the spark plugs. 4. Clean the engine and the entire riding mower thoroughly. NOTE: Use of a pressure washer or garden hose is not recommended to clean your riding mower. They may cause damage to electrical components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability. 5. Sharpen the blades so that the mower will be ready to use when needed. 6. Protect the metal surfaces. Repair scratches with the appropriate touch-up spray paint. Brush a rust preventive oil on any unpainted surfaces including the pulleys and blades. (Be careful not to get any oil on the drive belts.) 7. Clean and 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. 8. Lubricate all lubrication points. 9. Jack the mower up and store it on blocks to take the weight off of the tires. Removing the Riding Mower from Storage 1. Check the engine oil. 2. Fully charge the battery, lower riding mower off blocks, and inflate the tires to the recommended pressure. 3. Remove the spark plugs and wipe them off. Using the starter, crank the engine to pump the excess oil out of the spark plug holes. Replace the spark plugs and the ignition leads. 4. If drained before storing, fill the fuel tank with clean, fresh gasoline. 5. Check the level of the engine oil in the crankcase and the hydraulic reservoir tank. 6. Start the engine and allow to idle for a few minutes to ensure engine is operating properly. 7. Drive the riding mower without a load to make certain all the riding mower systems are functioning properly. Service Charging the Battery Test and, if necessary, recharge the battery after the tractor has been stored for a period of time. • A voltmeter or load tester should read 12.6 volts (DC) or higher across the battery terminals. See Figure 4-13. Voltmeter Reading 12.7 12.4 12.2 12.0 State of Charge 100% 75% 50% 25% Charging Time Full Charge 90 Min. 180 Min. 280 Min. Figure 4-13 • Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps. Servicing Electrical System A fuse is installed to protect the tractor's electrical system from damage caused by excessive amperage. Always use the same capacity fuse for replacement. If the electrical system does not function, check for a blown fuse. If you have a recurring problem with blown fuses, have the tractor's electrical system checked by your Cub Cadet Service Dealer. Relays and Switches There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your Cub Cadet Service Dealer. Deck Removal Remove the mower deck from the tractor as follows: 1. Move the tractor to a level surface, disengage the PTO, stop the engine place the control levers in the neutral/ parking brake engaged position. 2. Move the deck gauge wheels or rollers to their highest setting (lowest deck setting). 3. Remove the 'V' belt from the PTO pulley, located on the bottom of the engine, using one of the following two methods. WARNING! The muffler at the rear of the tractor may be extremely hot, and could cause serious burns. Use extreme caution when near the muffler. Allow the muffler to fully cool before removing the belt from the PTO pulley.
