When tests and adjustments are made to the transmission, remove both front and rear axle shafts, install the anti-pivot link, and lower the blade to the ground. Let only approved personnel on the machine. Keep other personnel off the machine and in view of the operator.
All tests and adjustments must be made with the oil in the hydraulic control system at normal temperature of operation. Be sure the linkage adjustments are correct before tests are made.

Direction Linkage
1. Put direction selection spool (1) in the NEUTRAL position.2. Make an adjustment to the length of rod (2) so that distance (A) from the center line of pin (4) to the face of cam (5) is 3.18 in. (80.7 mm).3. Install the cable assembly in neutralizer housing (6) so that distance (C) is .47 in. (12.0 mm).
