I have a DK35 with about 430 hours on it and I love it!! But I'm wondering if the hydraulic pump might be having some kind of problem. The backhoe will drop down to the ground with the engine running. I have to reach back about every 10 to 15 minutes and bring her back up. I have not noticed any leaking oil and hydraulic fluid was just changed and is up to level. Also I'm not sure if the FEL has the lift it's suppose to have(I think its around 1400 lbs at the pivot pins) and it seems to squeal alot when I try to pick up a good sized stone. Is there an easy way to check the pump pressure? Any thoughts? Thanks for any and all help!

Get a gauge and a male quick disconnect and take a reading from your remote outlet,As far as the backhoe dropping that is an internal leak either the valve or piston and has nothing to do with the pump.

Don't you have an 'up-right' lock on that hoe ?

I for one find it difficult to line up the holes on the lock to slide the pin in.

I can drive around for some time before the hoe weeps down.
