The thing is the track drives have a much
greater surface area than the wheeled ones
and thankfully the weight of the Yahama is
much greater as heavy wet snows put up huge
resistance due to the total weight of the
snow per cubic foot.
A track machine is slower which aids in
clearing drifts with greater gripping
power as long as there is no little
or no ice under the snow.
The Yamaha units are designed for the northern snows
of Japan which are of high volume and higher moisture
hence the sawtooth narrow flighting cross augers
which cut into the snow banks aggressively cutting
the snow into very small pieces and conveying it to
the center of the cross auger and forcing it to the
impeller to be cast away from the work area.
The snows in Newfoundland are of nearly the same
The open auger design is more of a problem in snow removal
because the snow is constantly be pushed to the center and
then the impeller is casting the snow away from the snow blower.
The problem is the impellers are not big enough on most of the
american made walk behinds snow casters and do not rotate fast enough.
IF the impellers were half as deep they would perform much better.
The other issue is the chutes plug because they get warm from the
friction of the snow blowing out of the chute and spout and the
Yamahas have a slippery plastic sheet inside the chute and spout.
Yamaha impellers are sized properly and have the amount of
torque and RPM required to get rid of heavy wet snow.
