Hi, i was plowing with my 2210 and the FEL when i noticed some hydrolic fluid comming out of the transaxle i saw it in the snow. I took to into the garage and on the left side right above the axle was a little cylinder about an inch and a half long, it was all covered in fluid. I noticed that when i let down the loader when the tractor was off it looked like air came out of this thing. What is this and what dose it do. I do not know if this is like an over pressure valve or what it is. Is this a problem or normal becuase its never happend before?
