having myself several kubota products .. i don't think that these two machines can really be compared. especially not on a piece of paper.
we are using both: a
bx2200 and a pt425. and we think that comparing the two is like comparing apples with oranges (as you native northern americans would say). They have both there proper application. But the price to buy, the cost of the replacement parts, the labor rate to repair are very different.
and mechanical parts except for the chasis you can find in any halfway decent mechanical or hydraulic spare parts store.
not so with the
bx2200.
we are not mechanics, we use these machines to make a living and don't want to spent our time repairing and tuning other than the required maintenance.
if you have to take any kubota product into the hills, they are mainly build for horticultural application in flatter terrain your pt will not let you down in difficult, snowy, icy, sandy, rocky etc terrain.
your pt test pilot (ha,ah,ha) i don't work for pt
