Levelling box problem

Post by tdickson » Wed Apr 04, 2012 9:50 am

Was using the 880 Selectamatic the other day to mow a couple of paddocks and noticed that each time I lowered/raised the 3PL that the handle on the levelling box unwound approx 1/4 turn. Is this a common problem and how can it be fixed?

MF had a spring clip which went over the handle but even they could "spring off" if that makes sense.

Best solution is to get a long piece of rubber. I used an old inner tube and cut a slice out of it so that you ended up with a huge circle of rubber about 2" wide, the more that you cut it on the angle the larger the circle.

Then undo the lift rod where it joins the linkage arm and slip this piece of rubber up the lift rod. Then you can put the rubber over the winding handle as well. It will take a few attempts to get the length right.

The rubber will stop the handle from turning and when you do want to adjust it you can pull it over the handle. It's not as handy for Q-cabs though.

You should see an offset hole each side of a raised lug on the rear of the levelling box, this is where the spring fits, as said, it's no more than a curved elongated lynch pin spring, plenty to be found on scrappers, fitted to all Selectamatic models up until the Qcabbed ones.
