I bought a 3600 a week ago and at the time I bought it the 3 point was slow but functional. I was able to use it brush hogging all last weekend with no issues. Yesterday I had it in the garage for an oil change and other maintenance and I tried flipping the lever for draft control to see what would happen. The quadrant lever and 3 point arms immediately dropped all the way down with zero resistance. In draft control mode the quadrant lever won't even stay up. If you lift the lever and let it go it just drops back down. I then put it back into position control mode and the quadrant lever will now stay up but the lift arms won't raise at all. FYI I have the single quadrant lever with the mode selector about a 3" long lever mounted below the seat. Any idea where to start to get the 3 point working again? Thanks for your help!
