Using Front Hitch Upper And Lower Locking Plates

Upper Locking Plate

Upper locking plate is used in applications that do not require front PTO, but greater front hitch rigidity is needed.

1. Remove and retain four locking plate cap screws (A) and upper locking plate (B).

3. Reverse procedure to install upper locking plate.

Lower Locking Plate

Lower locking plate provides torsional support to keep lift arms timed, but also allows front hitch to roll or float as lower plates flexes. This allows implements to follow contours. Although lower locking plate is factory installed with V pointed up for greater ground clearance, it must be inverted to provide PTO drive line clearance during front PTO operations.

1. Remove locking plate cap screws.

2. Remove lower locking plate (D) and rotate end for end, then flip locking plate over so that lower locking plate holes (C) are aligned with holes in front hitch casting. Locking plate V is now pointed down which provides drive line clearance for front PTO operations.

3. While holding lower locking plate with V pointed down (E) against bottom of front hitch, install previously removed cap screws.

4. Torque locking plate cap screws to specification.
