I've owned almost all sizes of the BXs, several of the Bs and one Grand
L3240 HST.
BXs are more maneuverable, easier to transport from site to site, 2 speed transmission, easy to break fan in the woods and closer to the ground.
Bs are good medium sized tractors that have higher ground clearance than BXs, 3 speed transmissions, no fan to break in the woods, easy enough to transport and usually more HP than traction.
Ls are heavy, even higher off the ground (better ground clearance but scary on hillsides because butt is higher off the ground), 3 speed transmission, no fan to worry about in the woods, heavier for transporting and better traction than any BX or B.
Lots of good info has been provided and now go to dealer and sit and drive different models.
I currently have a
B2620 HST FEL BH and wish I still had my favorite Kubota the
BX25.
I owned my first and last geared tractor, a
B2320, great tractor but hated the gear drive especially after owning HSTs.
My most used tractor was a
B7800 HST FEL because I had it when I was doing most of my work around my property and the second most used was the
BX25, again my favorite Kubota tractor. I use Kubota Fs for mowing and no longer use tractors for mowing. When I did use tractors for mowing I preferred using a Landpride 6' rear finish mower behind the Bs and Land a
BX1500 MMM (because it's a mountain goat on my hillside property).
Weight equals traction and weight eats up HP so a 32HP L will seem to not be as powerful as a 32HP B. The L will put the HP on the ground better than the B but that extra weight uses a lot of that HP. I went from a
B7800 (31/32 HP) to a
L3240 (32HP)to a
B3200 (32HP). 1700lbs to 3700lbs to 1800lbs with about the same HP so L seemed under powered but great on flat lands and big, really big. Transporting and driving.
Wish I had my
BX25 back and probably will in a year or two but I don't farm or do woods or maintain a mile or two of gravel roads. I do home hillside rocky treed gullied acres landscaping and maintain flat rental property with 6 septic tanks.
