I built a test set for my tractor. I am not real satisfied with them, but I am anxious to see how they work out. Telescoping stabilizers work (fine adjustment) because the holes in the rod are spaced differently than the holes in the tube, and there are enough holes in each for one to line up with the other about every 1/8th inch or so. On the 790, as well as many other JD tractors, the stabilizers, from mounting point to mounting point, are too short to have enough holes. It typically isn't possible to change the mounting points because the stabilizer would then hit the tire. This is what I've been dealing with on my 790. I have the R1 tires, which are narrower than any other option. So, it would be possible to move the mounting point on the lift arm further back, behind the lift rod. But, I wanted to keep the factory setup, and I wanted to build a set that was bolt on, using the existing holes. But, that meant that the body of the stabilizer is very short. I am not satisfied with the adjustment options, but time will tell. I also don't care for the yellow, but it was fast drying- I'm not very patient.
