Have had a problem with the BH76 on my new B3300SU. All functions work correctlyand with full power with the exception of the dipperstick, which extends normally and with full power, but does not pull back toward tractor with normal power. Dealer had for 2 weeks, (Tractor has 12 hrs on it) and ID'd it as a bad relief valve. Still does not seem to have as much power to the d-stick as before, but may be my perception. Details are in a thread on tractorbynet> forums> kubota> owning and operating. Thread title is "So the backhoe worked for 12 hours". Wondering if anyone here has experienced similar failure. Thinking at this point that relief valve may need to be adjusted for a little more pressure...Thanks in advance for any input.Mike
