MH 333 vs MH 33

[Harryaroo]

Can someone explain to me the difference between a MH 33 and a MH 333. The engines are slightly different... no live pto on either. Live hydraulics?

33, 333
Cu inch 203, 208
Electrical 6V, 12V
transmission 5Forward+R, 10 For+2R (Hi/Lo range shifter)
live pto available, available
independant pto NA NA
hydraulics engine mounted pump, engine mounted pump
steering manual, power available

333 had power adjust wheel option for rear tires, lower pto height,
rear end housing differant design for 3 point hitch mounting,
drawbar swing circle shorter to clear 3pth arms

Probably a few other things, but quick list for now
