I bet I could make dual adaptors on the front axle. 4 ag tires and something extra wide on the steers probably could support it without sinking when it's wet out. and with a dana 60, it could get a locker or limited slip or something. selectable locker or adjustable LSD probably the way to go for the application.
if it were 4x4 that would really be baller. Don't think that'd be an easy swap (nor worth it?) but being fully hydraulic it could be done. There was a factory 2 stage snowthrower setup too - and a cab that fit the ROPS.
I'll probably talk to him and throw a lowball, something along the lines of what I ought to have into the forklift it may be worth playing with.
