I have a BX2660, and spent several hours tilling with it Sunday.
To say it was bumpy is an understatement, its like sailing a small boat in choppy water, but that's because it's:
Little (96" LOA)
short wheelbase (55")
lightweight (1400 lbs fueled)
narrow (42" max, 36" track) machine
which is why I bought it after all, a traditional row crop machine couldn't negotiate my vineyard without taking out the vines on 6' center trellis.
add in a 458 lbs RTR1250 tiller running in heavy clay hanging 24" off the backend (did I mention I left the 220 lbs of front end weights in the truck?) and the front end understeers, front wheels spin without diff lock on overlapping stripes and it just beats you up if you fight it. :confused2:
But the field is tilled and 1/2 seeded, it ripped out some buried fence wires so smoothly I didn't notice till I hoisted it up and the retired property owner was willing to finish the job, so I don't have to charge him for my time, just the tractor's.
