Hi,<br>
I have a compact tractor (Snapper UGT 2060H) with a 4' front end loader that has started to act up. It has a 2 way control valve & 2 cylinders for the lift & 2 cylinders for the bucket. There is also a valve to control front and rear hydraulics (I tried all front & in the middle for both). The in line filter (just below the control valve) and transmission (hydrostatic auto) filters were also changed recently after the problem started.<br>
<br>
The symptoms are that the loader (up/down & the curl of the bucket) is moving much slower than normal and the bucket is spongy - with some effort, I can move it several inches by hand. And, when lowered on a down angle & the bucket hits the ground, it will move instead of holding position. I first thought it might be the valve body (crud blocking something or a seal damaged?) - I removed it & tried cleaning it. I did not remove the valves after noticing some corrosion near the lever on both valves - I thought if I forced it through the top seals, it could gouge the seals. I just removed one of caps & had a look. The other cap would not come off. What I noticed was everything was very clean inside. I placed it back on & not much of an improvement. The controls move easily, don't get stuck, & the handle returns to the "zero" position. <br>
<br>
Since there was only the sponginess to the bucket not the lift, I switched the hoses from the bucket and lift set of cylinders - not change to the sponginess of the bucket. My main question - it is likely the cylinders for the bucket (one or both leaking internally and will need seal replacements - a rebuild kit) - if that is the case, would that cause the lift and bucket to also operate slowly? Also, the rear lift cylinder (for a 3 point weight rack is not effected - moves fine, & the power steering cylinder doesn't appear to be effected) - so, I can only assume that the pump is fine. I could not find any fluid leaks (external leaks) or loose fittings. While I am mechanically inclined, I am not experienced with hydraulic systems. I could post some photos if that would help.<br>
<br>
In addition, prior to the problem - I had forks on the bucket while cleaning up tree parts. While pushing down a mostly cut tree (a fork on each side of the tree), it fell on an unexpected angle & struck one of the forks fairly violently on the way down - fortunately, it did not strike me & the tractor did not get pushed over. I won't try that again... The issue seemed to start some time after that. If that helps.<br>
<br>
Any help would be greatly appreciated.<br>
<br>
Thank you,<br>
