Removing the Battery (SD Models) 1. Flip the seat all the way forward. 2. Unhook the strap (a) holding the battery in place. See Figure 4-5 (a) (c) 6. Lift the battery bracket (c) off from the tab at the left side of the battery compartment and save for later reinstallation. See Figure 4-7 (b) (c) 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. (a) (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. Removing the Battery (SDL Models) 1. Flip the seat all the way forward. 2. Remove the hex screw securing the black negative battery lead (a) to the negative battery post (marked NEG). Move the cable away from the negative battery post. See Figure 4-6. 3. Remove the hex screw securing the red positive battery lead (b) securing the the red positive battery lead to the positive battery post (marked POS). Move the cable away from the positive battery post. See Figure 4-6. Figure 4-7 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 4-8. (a) 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. To change the transmission oil: 1. Remove the cap from the transmission oil expansion reservoir. 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 4-10. (b) (a) Figure 4-6 4. Locate and hold the carriage bolt (a) at the front of the battery bracket (c) to prevent it from falling. See Figure 4-7. 5. Remove the hex lock nut (b) securing the battery bracket (c) in place. Save the carriage bolt and hex lock nut for later reinstallation. See Figure 4-7. Figure 4-8 2. To release the bypass lever (a), push the lever forward. Hydrostatic Transmission The tractor is equipped with dual integrated hydrostatic pumps/transaxles that 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. (a) Figure 4-10 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 through the expansion reservoir slowly until the "FULL COLD" line. Allow the transmission oil to move through the system and top off as necessary. 5. Replace the cap and fully tighten. 22 Section 4- Product Care
