B2650 with less than 50 hours. Sometimes not all the time, when I have my bucket curled up on the air and I shut of the tractor, I can freely move the bucket by hand. Sometimes its locked like it should be. Any ideas why?
In my limited experience it is absolutely not normal.I think you guys misunderstood me. I probably didn't explain it properly. First, I do not leave my loader up in the air all night. I said it sometimes floats like that when its up in the air. Does anyone drive their tractor all over the place with the bucket on the ground? Up in the air could be 5 inches off the ground. When im storing my tractor its always on the ground with the hydraulics released. I always thought the pistons locked and the bucket didn't float like that. You guys are hooked on this "Dangerous" thing that I'm not doing. LOL. When my friends massey is relaxed state his bucket doesn't move at all. Just wanted to know if this is normal with Kubota?
Posting information like that on a forum that can be frequented by anyone is foolish. We have enough folks that can not discern problem solving without coaching them in the wrong direction. Lay under a full bucket ......got to be kidding!! Never. That's why the bulcket should be lowered when not in use, for safety.As others have said HUGE safety issue !!!
if you don't think it is, fill the bucket to max, raise to max, lay underneath it, then have someone 'simulate' a blown hose by cutting it with angle grinder or sawzall or skilsaw.....
Now as for WHY it happens, that's the way it was designed,engineered and manufactured. If you want to STOP it from doing it, simply add TWO shutoff valves in series with both lines AND turn BOTH closed when bucket is up.NOT 100% reliable but should work.
The float function should not affect the bucket tilt function, but your observation is interesting. If that is happening it could be an indication of an issue internal to the control valve itself. Which the floppy bucket also seems to indicate.From what I saw in the video you are putting pressure on the bucket with your foot while the bucket is lowered to the ground, and when you push on the bucket it also raises the loader arms a little. Is that correct? If so, it looks like you may have a sticky loader float valve. I would try spraying WD40 on the valve and work it with the tractor shut off. Work that valve in all positions several times with the tractor not running. Then try it with the tractor running and I think you will see improvement. If that tractor was stored outside before you bought it the weather may have caused a sticky valve and it may start working properly after working the valve for some time. Please post back with your results.
