I bought a used John
Deere 445 with a very precise hydrostatic transmission. It is great except when there is a sheet of
ice in front of the hangar and then this 25 horsepower tractor slides all over
the place. Even the Suburban with a tow
hook for the bar slips on the glare ice.

If I had it to do over again I would
have got a used lawn tractor with a tow bar.
1) traction. the physics
of getting a lot of wheel on that one wheel are just not great
2) steering. let's see
I'm pushing the airplane up the apron but I need to make a little turn here
and....Ooops....now we're going down the apron
3) momemtum. I honestly
don't know how the powertow is on this but I can tell you that the tow buddy
electric never achieves sufficient speed to use the airplane's 3000 lbs to get
you up and over the apron.
Compare 18hp tractor, lots of weight
including yours, really precise steering with no interruption in power, and
probably not so pricey.
