Cub Cadet Essential Maintenance for Your Hydro Transmission

TRANSMISSION OIL AND OIL FILTER

Checking the Transmission Oil Level

Check the hydro transmission/hydraulic system oil level before each use. Check the oil level only while the engine is stopped and the tractor is standing on a level surface.

•Locate the transmission dipstick on the rear of the transmission at the back of the tractor. See Figure 58.

•Clean the area around the dipstick to prevent debris from entering the transmission; then with- draw the dipstick from the transmission and wipe clean.

•Fully re-insert the dipstick into the transmission.

•Withdraw the dipstick again, and check the oil level. Always keep the oil level between the full and add marks on the dipstick.

•If the oil level is low, refer to the LUBRICATION TABLE for the proper type and quantity of oil to add to the transmission.

•Clean the area around the breather cap and fill tube on the back of the transmission to prevent debris from entering the transmission . Then turn the cap counterclockwise to unscrew from the oil fill tube. Refer to Figure 58.

•Slowly pour transmission oil into the fill tube while frequently checking the oil level with the dipstick. Add only enough oil to bring the oil level up to the full mark on the dipstick.

•Screw the breather cap into the fill tube, and reinsert the dipstick into the transmission and press firmly into place.

Changing the Transmission Oil and Filter

The oil in the transmission case is also used for the hydraulic system. The transmission/hydraulic oil and the oil filter (located on right side of tractor) should be changed after the first 50 hours of operation, then at 300 hours and every 300 hours thereafter. Refer to the LUBRICATION TABLE for the quantity and type of oil needed.

•Clean the area around the transmission dipstick and breather cap to prevent debris from entering the transmission. Refer to Figure 58.

•Locate the drain plug on the bottom of the transmission. Place a suitable container below the drain plug to collect the old oil. See Figure 59.

•Remove the dipstick and breather cap from the transmission.

•Turn the drain plug counter-clockwise to remove from the transmission, and allow the old oil to completely drain from the transmission. NOTE: The capacity of the transmission is approximately 9 gallons (36 qts.), so it may be necessary to drain the transmission in stages to capture the used oil and/or to ease emptying the drain pan.
