I have a L3010 with R1 ag tires and wheels. I would like to have a set of turf tires and wheels for it. I found someone that has a set off of a B3000. Will the wheels fit? Will the ratio be the same?
No they won't work.
Your L3010 should have 7.2-16 front and 12.4-24 rear R1's for 4WD
The B3000 should have 7-12 front and 12.4-16 rear R1's
And the B3000 should have 24x 8.5-14 front and 13.6-16 rear Turf tires.
