With slight mounting hardware modifications it will also fit on the AWS units X724, X729, X744, X749.
The X465 is suspect. It is either not recommended or the cowing for the air cooled engine gets in the way.
Personally, I would HIGHLY recommend a 4wd unit for the 45 loader. Two whee drive units are fine to a degree, but if you want to move more than 200-300 lbs at the time, the machine to be stable, and have traction a 4wd unit would be my pick.
Since 2013 I’ve put 350-400 hrs on my X748 with the 45 loader installed. A level bucket of black soil will test your patience in 2wd. Just my opinion and experience.
