422 will not stay in float

[muncybob311]

So after 1400+ hours float is not working correctly. The slightest bump in terrain pops it out and now I also notice when lifting the bucket (or whatever) the lift continues after I let go of the handle. Plan to call Terry tomorrow and wondering if it's an easy fix like a cleaning of something or is it time for a new part?

Inspect the linkage going from the handle to the valve spools. If it is worn it may not be pushing the spool in to the float position fully and maybe jamming up when going into the raise position. Also look for rust, loose parts, foreign material, etc.

I think it would be great to call Terry.

If the bucket lift continues after you let go of the handle, I'd suspect a bit of debris in the valve. I suspect that @m5040's diagnosis of loose or sticky linkages could be an issue in the not staying in float, and possibly why the lift continues after releasing the lever. How often do you clean and lubricate the linkages and lever ball?

All the best,

Peter
