I have a BH92 on a L3940 HST Cab, and have been digging tree stumps for about 18 months. It seems to do fine. My only complaint has been the main controls seem to be not as robust as the physical portions of the back hoe. I've had o-rings go out twice, and only at 350 hours. Not sure how much less flow you get on the 3240 compared to 3940, but power hasn't been an issue for me.
