I’m new, to tractors, to kubota’s and everything. So I bought a B7100 4wd gear drive. Then I bought a FL850 tiller. Next I figured out… my pto on the tractor side has a block off plate. So I go back to the place I bought the little tractor from and the guy says o yea we were going to swap the pto from this unit to yours…. Here are the parts. So I’m a handy guy, but the gear ratios or more appropriately the gear sizes are not meshing properly… but I did get the cover with the actual pto shaft and another gear for the bottom shaft. Where would a guy look to sort this mess out? Any help would really be appreciated.
