Yakima,
B21's are running about $24K from Carver - click on the link at the TBN home page for kubota's. Box scrapers are $4-800 pending size and construction. Locallynew B21s are running about $25K with some rebates in effect ($700 for
B21's) you might get a little better price.
Regarding Dick's post on the
L35 these are also very tough units with more capability, and price, about $32K range, but have no HST which in a TLB is very nice to have.
The
B21 weigh in at 4000lbs and the
L35 at 6000Lbs so for trailering there's a difference. Plus OH clearance you will need 93" for the
B21 and more (not sure how much for the
L35) but an 8' door is needed for the
B21.
As far as driveway work, the
B21 will handle that with even at a 20% grade. Will take a little longer than the
L35 or larger due to the size of the rear tools. By the way, the 21 gets around trees and stumps very well when in the woods esp with the hydro, plus when in the BH, to move forward/back lift the stabilzers and FEL, and press the foot pedal to move - no changing seat position from the hoe.
