Had a couple tips for any of you JX75 people out there that you may or maynot already be aware of. The biggest issue I have with my JX was the ride height control. You would hit a bump and the aluminum deck would begin to round out and the lever would bump down to a lower setting. Well I checked with my JD dealer and you can buy the Height adjusters from the JX85 mowers but they wanted $50 a corner! I figured I could come up with something better then that for a lot cheaper! When I started to investigate why it would happening I found a couple things. First on the rear. The drive system is held together with a steel plate that rests on the outside of the rear part of the deck. With the angle of the control lever at two or three setting the steel plate was actually pushing the height adjuster out away from the deck body. I took an angle grinder and removed some of this excess steel plate and now the height controller is at the correct angle and the little pin sits all the way into the aluminum cut-outs. No more problem in the back! It was also happening in the front. That was called from the height adjuster lever being angled towards the deck. The lever was actually hitting the top of the deck keeping the pin from setting deeply into the cutout. I took out my handy dandy angle grinder and ground about 1/8" off the top of the deck until the pin would sit deeply in the cutout. That fixes that too! A little JD green paint and poof! looks good and functions properly! Now if only I could find a bigger bag... Any one?
