Backhoe No hydraulic power to bucket or backhoe!

Drain some of the fluid in a glass jar and let it sit for a while. Then compare it to some new fluid.

Install a hydraulic gage and monitor the pressure, if any, but that is a clue also.

I agree. Looks like water contamination. Do you run it for only a few minutes at a time alot? Oil may not be getting hot enough to burn off the condensation. Could be time for a fluid/filter change.

Hi folks,

It has been a while since I have been online. Yes, I changed the fluid and found it was almost like 2 liquids draining out - one like hyd fluid and the other more milky. I am certain moisture got it there somehow. when I pulled the filler cap, I could see moisture droplets condensed on the inside of the tube. After changing the fluid and filling to the proper level the sight glass looks like it should - clear, like oil to just under the top of the full mark. When I changed it, the strainer filter (looks like a big bolt requiring removal of rear left tire to clean) did capture a bunch of what looked like an excessive amount of metal filings. I showed them to a few guys who know tractors and hydraulics... they said it is normal and suspect it is probably the first time it had ever been checked... we guess even though the dealer performed the full service @ 50 hours, they probably didn't clean this strainer since it requires rear wheel removal. As an aside, I followed the manual and pulled the drain plug first, then later pulled the big strainer bolt. When pulling out the bolt I could feel stuff that was stuck to the strainer screen catch on the housing as I extracted the bolt... so some junk was left in the case. In retrospect (and how I will do it the next time) I should have pulled the strainer bolt FIRST and let all the fluid drain out of this hole.... then later pull the drain plug. This way, if any junk scrapes off the bolt, it will get flushed out anyway.

So my dad tricked me in November "just bring the tractor to my house for the afternoon".... well here we are 5 months later and I think I have finally convinced him to let me take it back home . Recall, my original problem was that the hoe functions worked, but just not with a great deal of force. Yesterday dad he was hoeing and this time there was total loss of pressure to the hoe. The FEL worked perfectly so it isn't a pump issue. He said the boom, dipper and hoe would not do anything. He shut the tractor off, waited a few secs and started it up - everything worked again. What could be going on here? is there a pressure relief valve that could be sticking open impacting the hoe but not the FEL?
