Cut Height Changes by Itself

I checked the adjustments out on my deck and it was way off front to back. I leveled that up.

Next I checked the all the way up position in relation to the stop, and mistakenly adjusted that with the lift link rather than the double nut in the back. So, once I discovered the errors of my ways, I readjusted again. I hadn't used it in between.

When I adjusted the second time, since I had to readjust the lift links anyhow, I set the knob on 2", then took a piece of 2" square steel tubing, and adjusted til the blades were even with it. All this was done on a concrete garage floor. So, mine should be pretty good now.

But, who really cares if the dial says 2" and it is actually cutting it 3". Just adjust it til the grass is the length you want it and don't worry about what the knob says. Just remember what you set it on for reference in case you change it, or the ghost of KuBOOta changes it, ha, ha.

As far as the wheels, I set mine to be just clear of the garage floor with the deck at 2", which is where I cut. That is one hole lower than the chart for the self-balancing deck shows, but I figured it would be better a little too low than too high, as far as scalping goes. Maybe when I mow tomorrow I'll try them up one hole and see what happens.

Well, I mowed again yesterday. I started out by setting the wheels where Kubota tells you on their chart for the self-balancing 60" deck. Contrary to my statement above, I actually had my wheels one hole HIGHER than the chart recommendsk, not lower.

With the wheels lower, the adjustment was changing itself constantly, so I stopped and took them up one hole. That puts them just off the concrete floor with the deck in the 2" cutting height I use. The adjustment stayed put much better, but still changed once in a while. My deck may be a little lower than 2" after I adjusted it and maybe that's why the chart setting for 1.5" works better, I don't know.

I think when the wheels hit the ground, it is taking the weight off the stop and it is free to vibrate or bounce into a different setting. At any rate, it is a very annoying problem. Having to remember to keep checking the adjustment takes away from the pleasure of seat time.
