Removing the Battery 1. Flip the seat all the way forward. 2. Unhook the strap (a) holding the battery in place. See Figure 4-5 (a) (c) Hydrostatic Transmission (500 Series) The hydrostatic transmission on the 500 series is equipped with a filter and dipstick. To check the transmission oil, locate the dipstick on both the LH and RH transmission assemblies. See Figure 4-7. Full Hot H (a) Full Cold 1/8" up dipstick (b) Figure 4-5 3. Remove the hex cap screw and sems nut securing the black negative battery lead (b) to the negative battery post (marked NEG). Move the cable away from the negative battery post. 4. Remove the hex cap screw and sems nut securing the red positive battery lead (c) to the positive battery post (marked POS). 5. Carefully lift the battery out of the tractor. 6. Install the battery by repeating the above steps in the reverse order. 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. Engage the transmission bypass valves by pulling the bypass lever (a) upward and all the way back. See Figure 4-6. (a) Figure 4-6 2. To release the bypass lever (a), push the lever forward. Figure 4-7 Remove the dipstick and check the oil level. When cold, the level should be no higher than 1/8" up on the dipstick. When hot the level should not exceed the "H" mark on the dipstick. Exceeding these levels could cause the oil to overflow when hot. To change the transmission oil: 1. Remove the dipstick. 2. Place a suitable container under the drain plug (a) on the transmission. Remove the drain plug (a) and allow the transmission oil to drain. See Figure 4-8. (a) Figure 4-8 3. Using a pair of needle-nose pliers or a magnet remove the filter. 4. Replace the filter and drain plug (torque to 115-135 in-lbs.) and fill the transmission assembly to 1/8" up on the dipstick. 5. Replace the dipstick. Note: Make sure the dipstick is full tightened. If the dipstick is not fully tightened, transmission oil could leak and cause damage to the transmission due to insufficient oil. Hydrostatic Transmission (700 & 900 Series) The 700 and 900 series are equipped with dual integrated hydrostatic pumps/transaxles that are sealed and are maintenance-free. However, this model is equipped with a transmission oil expansion reservoir. Under normal operating conditions, the oil level in the expansion reservoir does not need to be checked and no additional oil is needed. If checking the reservoir oil level, proceed as follows: WARNING Check the oil level ONLY before starting the tractor when the transmission oil is fully cooled. 1. Pivot the operator's seat forward and clean the reservoir cap and the area around the cap to prevent debris from contaminating the transmission oil. See Figure 4-9. Figure 4-9 2. Turn the reservoir cap counterclockwise to re-move, 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 4-9. 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 Operator's 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. Section 4 - Product Care 21
