Lay the plow on the ground. The plow should be lengthened out so that the plow end is on the far side and the engagement rod is on the other end.
Detach the angle handle on the plow.
Roll the tractor over the length of the laid out plow. Stop the tractor when the rear axle hitch is right above the engagement rod on the plow.
Lift the rear of the plow and attach it into place on the rear axle hitch.
Lower the lift handle and install the lift rod into the left bar.
Reattach the angle handles. Make sure that you use some grease on the pivot points.
