i have a 2013 s530 bobcat and have used my aux hydraulics before for brush hogging with no issue. I bought a well used bobcat brand rock rake 6a and it works fine at first, but today was first time i actually used it for more than 10 minutes and after about a half hr or so i noticed it start to run very slowly. Then if i mess with the hydraulics it was speed back up then slow down again. Seemed like it happened when i diverted flow to raise the rake unit for dumping. After a while it seemed to run at normal speed under no load but when in contact with ground would begin to slow down and loose power again. Im not sure if this is a hydraulic issue with the diverter block a worn out hyd motor or whats going on. As i said the machine aux hyd has no issues on any other attahcment i have used. Not sure if heated up fluid is causing a issue or what.. just wanted to see if any one has had this issue or has any pointers.

Sounds like a hyd. motor on the attachment. Someone on here likely knows how to check that for sure. I had one of those when the A series first came out. I didn't have that issue, but about everything else. I traded it off and got a FFC Preparator, and have stayed with that brand (I have worn out 3 of those in 20 years) not perfect either but a lot more HD than the Rockhound rock rake.

Its a gearroller type motor. Very easy to dissect (with a manual present), and the control valve body comes apart easily for inspection.
As for heat, where is the throttle valve set?
