PRODUCT CARE Using the Transmission Bypass Rods WARNING Do not tow the mower, even with the bypass valves engaged. Serious transmission damage will result from doing so. PARKER TRANSMISSION (IF EQUIPPED) If for any reason the mower will not drive or you wish to move the mower, the two hydrostatic transmissions are equipped with a bypass that will allow you to manually move the mower short distances. 1. Engage the transmission bypass valves by pulling the bypass lever (a) upward and all the way back (Figure 41). To check the transmission oil, locate the dipstick (a) on both the LH and RH transmission assemblies (Figure 43). Full Hot H a Full Cold 1/8" up dipstick a Figure 41 2. To release the bypass lever (a), push the lever forward (Figure 41). HYDRO-GEAR TRANSMISSION (IF EQUIPPED) 1. To engage the transmission bypass rods, pull the rod (a) up into the larger opening of the key slot, then pull back until the collar on the rod passes through the frame (Figure 42). 2. Lower the rod back into the smaller opening of the key slot, making sure the collar is secured on the outside of the frame (b). Repeat on opposite side (Figure 42). Figure 43 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 (Figure 43). 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 (Figure 44). 700 Series 900 Series a a b a b Figure 42 3. After moving mower, reverse Steps 1 and 2 to disengage the bypass rods. Hydrostatic Transmission (500 Series) PARKER TRANSMISSION (IF EQUIPPED) The 500 series with Parker hydrostatic transmission is equipped with a filter and dipstick. Figure 44 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 fully tightened. If the dipstick is not fully tightened, transmission oil could leak and cause damage to the transmission due to insufficient oil. 6. Drain old oil filter prior to disposal. Place used oil in appropriate containers and deliver to an approved recycling collection facility. HYDRO-GEAR TRANSMISSION (IF EQUIPPED) The 500 series with Hydro-Gear hydrostatic transmission is equipped with dual integrated hydrostatic pumps/transaxles that are 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 mower when the transmission oil is fully cooled. 26
