CHANGING TRANSMISSION/HYDRAULIC SYSTEM OIL

Change the hydrostatic transmission/hydraulic system oil and filters after every 200 hours of operation. The dry capacity of the transmission/ hydraulic system is approximately 26 quarts.

Change the transmission/hydraulic system oil as follows:

Operate the tractor for a short period to warm the oil to the normal operating temperature. Place the tractor on a level surface, engage the parking brake, and stop the tractor engine.

Remove any belly mounted attachments.

Clean the area around the transmission drain plug and the oil fill plug/dipstick to prevent debris from entering the transmission. Refer to Figure 44 and Figure 45.

Place a suitable container(s) beneath the front of the transmission housing.

Remove the oil fill plug/dipstick to help vent the transmission, then remove the drain plug and allow the transmission oil to drain into the container(s). Reinstall the drain plug after draining the oil. See Figure 45.

Dispose of used oil in an environmentally safe manner. If necessary, contact your area EPA office for proper disposal proce- dures and recycling center locations.

Clean around the base of the hydrostatic transmission oil filter and remove the filter by turning it counterclockwise. See Figure 45.

Apply a light coating of clean transmission oil to the gasket of the new filter. Install the filter by turning it clockwise, by hand, until the gasket contacts the filter base on the transmission housing; then tighten the filter an additional 1/2 to 3/4 turn.

Clean around the base of the hydraulic system oil filter and remove the filter by turning it counterclockwise. Refer to Figure 45.

Apply a light coating of clean transmission oil to the gasket of the new filter. Install the filter by turning it clockwise, by hand, until the gasket contacts the filter base on the transmission housing; then tighten the filter an additional 1/2 to 3/4 turn.

Loosely position a funnel in the oil fill hole so that there is enough clearance around the fun- nel to allow the transmission to vent while the oil is poured into the transmission. Fill ONLY to the full mark on the dipstick, never overfill the transmission.

NOTE: Always use Cub Cadet hydraulic oil and filters to ensure correct formulation and filtering capacity. Substitute oils and/or filters could affect performance and may cause damage to the transmission.

Reinsert the oil fill plug/dipstick into the transmission housing and turn clockwise until tight.

Start the engine and allow it to run for a few minutes. Shut the engine off, then check for leaks and recheck the oil level in the transmission housing.

CHANGING HYDROSTATIC TRANSMISSION AND HYDRAULIC SYSTEM OIL FILTERS

NOTE: With the exception of the first oil filter change after the 25 hour break-in period, the hydrostatic transmission and hydraulic system oil filters should be changed along with the hydrostatic transmission/hydraulic system oil after every 200 hours of operation.

Initial Break-In Period Filter Change

During the initial hours of tractor operation, contaminants caused by the normal break-in of internal transmission and hydraulic system components will collect in the oil filters. Because of this, the filters should be changed after the first 25 hours of operation.
