I found a HFWA axle and wheels (everything needed) that a neighbor took off a 1850. I was curious about how well they worked and operation of them. I am considering putting it on my 1750 but am not sure how much of a pain it will be. 
Also what is this unit worth and does it increase the value of the tractor. Would I be better off piecing the 1850 back together that it originaly on from the factory...does the serial number reveal #'s matching? The 1850 is SEVERELY cannibalized and has been setting out for as long as I can remembe..no engine so on so forth.

Any information would be useful. Dont know much about the units.

Thanks WR
