Determine the weight of the trailer by looking at its data plate. The trailer weight plus cargo must be less than 250 pounds to be safely towed with the Scag.
Reverse the Scag up to the trailer aligning the hitch with the trailer's coupler.
Insert the coupler around the hitch and insert a hitch pin through the trailer's coupler and mower's hitch. Lock in place with a cotter pin through the bottom of the hitch pin.
