I have a 2025r with a factory installed backhoe, my 3 point came in a box. I installed the 3 point, leveled it using the adjustable side link. I connected the rotary cutter and went to adjust the rake, 2" higher in the back than the front and immediately ran into a problem, my toplink is all the way tight and the cutter is sitting level front to back. it looks to me like the way to raise the rear is by tightening the toplink. How do I raise the rear?
