when the PTO shaft is not connected to the gear
box on the cutting unit.

1. Insert a support rod into each end of the rear tube on
the attachment frame (Fig. 2). Make sure the thru hole
is positioned at the top.
2. Loosely attach the bottom of each support rod to the
attachment frame tube with a 1/2 x 1 inch capscrew,
1/2 inch lock washer and 9/16 x 1–3/8 inch flat washer
(Fig. 2).
3. Position the attachment frame under the lift arms.
4. Move the lift lever to the Float position. Push a lift
arm down until the holes in the lift arm line up with
the holes in the attachment frame brackets and the
support rods can be inserted into the lift arm pads
(Fig. 2).
5. Secure the lift arm to the attachment frame brackets
with (2) thrust washers, a clevis pin and a hair pin
cotter. Position the thrust washers between the lift arm
and the attachment frame brackets (Fig. 2). Insert the
end of the cotter pin into the slot in the attachment
frame bracket tab to retain the cotter pin.
