Backhoe backhoe trouble

[gumper48]

took delivery of a ck30 hst w/ bh,fel on friday afternoon.
sat am real early snook off and started digging a hole to bury some stumps. started out great guns bh was doin' it. then she started to get more and more sluggish till she would not even pull the bucketout of hole.
called dealer and was told to reverse line hook ups, no help.
checked fluid level- ok there.
no leaks.
let her sit for about 30 minutes then started it back up, bh was working again -- but not as strong as earlier. kept diging and she finally petered out after fifteen minuts or so, fel would not hardly pick its own weight up.
bad hydroulic (sp) pump ?
tractor had 4 hrs on when it was delivered. 9 on her now.
any thoughts ??
any input appreciated
thanks in advance

Do you have the aux. vavle set up or the "hose kit" setup on the tractor?

Did the hyd fluid get super-hot before it stopped working?

Hopefully you are back in biz now that it has been a week. Pls
post your cause.

thanks for the replies-
the backhoe started to work ok after a cooldown and as soon it got hot again it would start to loose digging power.
dealer picked her up the next day and it would not do what it was doing till she got warmed up. then she lost power.
dealer tokk it to shop and ran a pressure test on hydro pump and it was putting out only 1600 (?) so he replaced the pump and was getting 2500 (psi ?) . anyway she is a digging machine again.
had a chance to give the 48" grapple a work out and am very pleased with it's performance, will pick up some big stuff if you grab it in the middle.
it will pull the 5 ft bushhog along just fine right through this heavy , 1 1/2 years growth.

she has 18 hrs on her now and i noticed that she doesn't idle smoothly but surges about three hundred rpm. at working speed no surge.

thanks again for the replies.

now if i could only get pictures on here.
where do ya'll post your pics to upload?

Upload right from your computer to the site. You just need to shrink them first to be sure they are not in excess of the maximum file size.

I am anxious to see a grapple pic. I grew tired of shuttling slash over 200 feet to the burn pile last weekend and am seriously looking into a grapple arrangement.
