RE: (ET) How much can an E15 pull?



A couple of thoughts:

The idea of a grossly inadequate 1 wheel brake on a tow vehicle is more weight limiting than the horsepower. Imagine trying to control a 2000 lb trailer going down a grade with an E-15. One long black skid mark (assuming the brake holds together) all the way to the river........

Unlike gas motors, electric motors make maximum torque at stall torque. However, if the object is to move a wagon load of equipment, the speed at which you are pulling may be important - you probably want to move at a walking speed. Thus when evaluating pulling ability, don't look at the maximum pull - that was probably done at a low speed and ultimately ended when the tractor ran out of traction or stalled. The question should be "how much can I pull at xx miles per hour?"

Stephen,

I think this is a great idea. Here some thoughts
on this subject (no hard data though):

Here is an amusing post from 1999 about an E20 doing a
full-pull at 1450# in garden-tractor pulling:
http://cosmos.phy.tufts.edu/mhonarc/elec-trak/msg00678.html

You have two consider two things. One, the E15 has a bit of
a smaller motor. Two, pulling a rolling weight is much easier
than a tractor pull sled that slides on the ground.

I quickly checked my "Commercial Applications Guide" for the
ETs. It has two pages devoted to how great the ETs are for
towing but it doesn't give any numbers. On the front page of
this guide it shows an E15 pulling a "train" of four large
industrial carts, two loaded with about 8' high heavy machines
one with pipes and the last with six oil barrels. They call
this an elec-trak "trackless train"

It says "at aitports, the system is ideal for baggage handling or
even spotting and moving aircraft in and out of hangars"

Electrictractor.com lists 8000# for their much smaller tractor
in pulling application. From looking at their motors etc. I am assuming
that an E15 can  pull much more.

Braking is another issue to consider. But if you have
separate brakes in the trailors then I guess you'd be fine.

Just my two cents worth

Markus
