Re: (ET) Hybrid Electrak?

Nod. So how long were you blowing snow? In our snow I was pulling 150a with a 20 degree slope.

In the 2 feet of wet snow I would pull 300 amps and up. I'm curious how lead batteries compare to nickel.

This is the first snowstorm where the standard pack or the plow didn't
cut it.     Which is why I was thinking about a nice little Honda
generator strapped to the back.   For these rare occasions I wasn't too
concerned about keeping it all electric, just needed to get my drive way
cleared.   J   I had to have someone with a pickup truck plow me out
anyways.

I have, and it worked just fine, but it was a pretty un-ET way to solve
the range/run-time problem. Loud and smelly. And my old 4-stroke
generator is as bad as any Briggs and Stratton 4-stroke... notorious.
 
I later did two things: 1) got a fresh string of batts, and 2) kept the
old string... I added a "back porch" to my tractor, and ran the second
string in parallel with the on-board batts. I'm west of Boston, and I
moved a huge amount of snow on every charge with that rig.

I'm about to do the same thing to an E-20 with a plow... need more
range/run-time, and better traction again.
 
Best of luck to all you ETers,
 
love those tractors!

I have a 200' driveway that is paved and flat, but here in New England
we just got hit with 19" of snow.     The E12 tractor got about 3 feet
out of the garage before it couldn't go any farther.    I put the snow
thrower on and I made it down the driveway and almost back to garage
before my batteries didn't have enough charge to throw snow.
 
Has anybody tried hooking a gas powered generator up to the tractor to
extend its range for extreme cases like this?
