If the money is not a factor........then get the B - it is bigger (good and bad point)
stronger.........
heavier.......
more HP - (well , it is a slightly bigger engine - book says say engine HP)
B has 3 ranges vs 2 for the BX
B will pick up more weight front and back........
Looking at the price on the B .....something is not right ............
the BX is right in line with the typical price of one with a little discount......
but the B is several K too high ???? look at my picture and tell me what I forgot.....
you ought to be able to get this for under 25K .......they are harder to find....
If all you are going to do is cut grass - the BX is more than enough - the B is a fine - fine machine , but FOR your purpose, not sure the price is "right"
would make more sense to buy the BX and then spend the other 7K on options for the BX ....
The BX is a very popular model (more sell than any other Kubota - for good reason) - it does so much !!! AND I bet your other 10% of the time not cutting grass will be closer to 25% doing something else with a new found work horse.
