the previously assembled truss and connect to
the torque tube using two 1 x 4½ headed pins

the end of the hitch and bolt in place as shown

Secure with 1½ slotted hex nut and ¼ x 4 cotter
pin. Use the 1½ machine washers as needed
for proper fit. Connect the turnbuckle (11)
between the side plate assembly and the H-
bracket (1). Use a 1 x 4” clevis pin (12) with
machine washer and 3/16 x 2 cotter pin at the
