Loader Kubota LA211 FED loader dump/ rollback quit while plowing snow

[SquirrelRidgeFarm]

Hi, all..... I was happily plowing the first snow of the season and 15 minutes in, the dump/rollback function quit. The bucket is sort of midrange between the dump/ rollback extremes. The arms go up and down normally. When I try to dump/rollback, the hydraulic lines jump a little(like normal) so I think there is pressure to the cylinder. If I put the arms all the down and try the dump/rollback, it will work to the point that it will lift the front wheels off the ground. So.... when arms are down, the cylinder works. I checked the hydraulic dipstick and I have fluid.

Any ideas? Any suggestions as to what to try first? Many thanx...... We are currently mid-blizzard and I plowed my 1/4 mile driveway with a walk behind snowblower, but I don't want to do that too many times!

YA, plug your hoses in properly.

Ice in the control valve or defective control valve if the hoses are properly plugged in. Can you float the FEL?

If not a simple QA that popped off, I'd bet on something loose or broken in the control lever to control valve linkage. Bunch of little pins and clips in there.

Make sure your 3PH lift lever is in the neutral position.

What roms are you running at? If u are running at low rpms try ramping it up a bit.
