1. Remove original seat and suspension from the cab.
2. Determine if your seat well has an angled front section or a square front section. For models with the angled front
section, use the JD W43A plate. For models with the square front section, use the JD W43B plate.
3. Bolt W43A or W43B plate to the bottom of the PED JD 43 with two 5/16" x 3/4" carriage bolts and flange nuts.
4. Place the PED W43 into the seat well in the location it will be fastened. It may help to bolt the JD W43 Plate to the
back of the cab using the original bolts to secure it. Check to make sure the W43A or W43B plate, which ever is
installed, is tight to the front section of the seat well. Loosen the bolts and adjust if necessary.
5. With the PED W43 assembly in place in the seat well mark the location of the front holes onto the seat well.
6. Remove the PED W43 assembly from the cab and drill two 11/32" holes through the seat well where you marked.
