   Not familiar w/ the 247B but I had same problem with my Bobcat, to Isolate the situation , Hooked up my auger and was getting a slow to start rotation in auger rotating clockwise and counter clockwise, sometimes no response, so the source was in the auxiliary Hyd. toggle switch not letting aux. solenoids to get current to actuate aux. spool valve. You might want to check auxiliary solenoids for continuity or it might be in auxiliary spool . the the correct resistance on My bobcat t 190 on the spool solenoids is about 4.9 ohms. if you have manual you might ck to see what yours would be for you unit.

   Make sure the micro switches in the joy stick are not sticking. I have seen the boots torn and it lets dust and debris in the switch hole.

   Check the quick connects have seen then come apart and act as a check valve.

   Actually just before the problem started the hydraulic line to to grapple came off while doing a job. I reconnected it and I think that's when it started acting up. Very helpful! Thank you!
