Using the Transmission Bypass Rods If for any reason the tractor will not drive or you wish to move the tractor, the two hydrostatic transmissions are equipped with a bypass rod that will allow you to manually move the tractor short distances. WARNING! Do not tow the tractor, even with the bypass rod engaged. Serious transmission damage will result from doing so. 1. From just in front of the two rear tires, locate the transmission bypass rods. Refer to Figure 1-4. Keyhole Slot Transmission Bypass Rods Tractor Storage If your tractor is not going to be operated for an extended period of time (thirty 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. Figure 1-4 2. Pull one rod toward the front of the tractor until the flange on the rod is forward of the keyhole slot in the frame assembly. 3. Lower the bypass rod into the keyhole slot and release so the rod flange is against the front of the frame bracket. 4. Repeat the above procedure to engage the other bypass rod on the other side of the tractor. 5. After moving the tractor, disengage both bypass rods. Lift the rod and guide the flange of the rod back through the larger circular opening of the keyhole, then release the rod. NOTE: The tractor will not drive with the bypass rods in the engage position. Battery Storage 1. When storing the tractor for extended periods, disconnect the negative battery cable. It is not necessary to remove the battery. 3. 2. All batteries discharge during storage. Keep the exterior of the battery clean, especially the top. A dirty battery will discharge more rapidly. 4. 3. The battery must be stored with a full charge. A discharged battery can freeze sooner than a charged battery. A fully charged battery will store longer in cold temperatures than hot. Refer to chart below. 4. 26 Recharge battery when ever the specific gravity value is less than 1.225. Section 6- Maintenance & Adjustments b. Using a fuel stabilizer: • 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: • Prior to putting the tractor in storage, monitor fuel consumption with the goal of running the fuel tank empty. • Close the fuel tank shutoff valve. Disconnect the fuel line from the carburetor and put the end into an approved fuel container. • Open the fuel tank shutoff valve and drain the fuel tank and line into the approved container. Reinstall the fuel line on the carburetor. • Start the engine and allow it to run out of fuel. This will prevent gum and varnish deposits from forming. Replace the fuel filter. 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. Clean the engine and the entire tractor thoroughly. NOTE: Use of a pressure washer or garden hose is not recommended to clean your tractor. 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.
