McFarms, I would say that you need to drain the hyd. oil from the little cover underneath the feederhouse. There are 3 bolts on the reverser right above the safty stop. take them lose drain the oil from the cover and tighten the three again. There is probably oil bypassing an o-ring and not letting the reverser engage. There is a pip for this problem.
Good luck,
