Transmission Oil & Filters
Transmission oil lubricates transmission, center housing,
and rear axles and also serves as hydraulic fluid.
Transmission oil and filter should be changed after first 50
hours of operation and then every 200 hours thereafter.
FIG. 60: To Check Transmission Oil Level - Park Trac-
tor on level ground. Oil level should be indicated in oil
level window, 1.
Oil level is replenished, as necessary, by removing filler
plug, 2, and adding oil through filler opening.

rect oil level in center housing and rear axles.

plug, 3, and completely drain oil from system.
