I would think the torque required with chains would be the same torque
required on dry pavement without chains. Could the manufacturer be pulling
your chain?

We own an older 110v electric corded model. We bought it used and cheap.
The cord doesn't bother us but tire chains are not available for this
model
because... the company says.... the increased torque that would be
required
if chains were installed would burn out the electric motor... hmm...
dunno.

Chains are available for the gas powered models. I know of several
Bonanza
owners who have no problems starting their relatively new PowerTows.

Would you recommend the electric version or the gas version. We're in
eastern Canada and the winters can get chilly... i've seen people at
the airport with these powertow tugs trying to get them started... the
electric one would seem to be start a lot easier.... any thoughts?
