After installing the rake on the tractor get it on a level surface. Let it down, hold your hand out with the thumb pointed down and the other fingers extended, rotate the hand until the tip of you thumb is in about the five thirty position. This is about what the rake should look like when in use. Adjust you top link, shortening it will raise the rake up at the rear, lengthening the top link will force the rear of the top link down. If your top link is to long and is already as short as you can make, you may a the wrong top link. Either way contact the dealer and obtain the correct length for the top link or check the owners manual if yo have it to see if the top link length is listed.
