I don't believe Kubota is trying to phase out the 4 cylinder. They are putting the 3cyl in the smaller B series ( B2320, B2620 and the B2920 ) and They are keeping the 4 cyl in the larger B series ( B7800 and B3030 )
B2920 is 3cyl 29hp Weight 1554lbs
B7800 is 4cyl 30hp weight 1741lbs
B3030 is 4cyl 30hp weight 1852lbs
Loader Difference
Smaller B Series LA364 is 952lbs at the pivot pin
Larger B Series LA403 is 1091lbs at the pivot pin
I think there is too many models. I wish Kubota would narrow it down alittle. They want to have a tractor to fit anyones needs.
