Re: (ET) New Electric Tractor

     Pure speculation on my part....................... {You know the spiel. "I'm not an EE, nor do I portray one on TV. " :) } but since the power pack consists of only four units, is it not reasonable to assume that this has a 24V nominal system.If that be the case, are we not looking at a system that is less capable to begin with ?

great this guy is stepping up and offering the conversion kits.
 
One thing I wonder about is the patent logo and this part of his description
"The patent pending speed control interlock (SCI) will automatically select the correct speed for the conditions of the grass.  If the grass is very heavy it will slow down.  When the grass thins out, the tractor will automatically speed up again"
 
Now , doesn't that mean that the thing is powered marginally and whenever the grass gets heavy and the mower motors draw more current the drive motor will slow down a bit. Wonder if that's all there is or if he added some controls that amplifies this effect by e.g. sensing the mower motor current and adjusting the drive motor current to ease the load on the mower motors by slowing down the drive motor.
 
Also I would be interested how good his electric brakes are. With no manual brakes I have my doubts that it
could pull (well actually I mean stop) a trailer on a slope. Sort of like our ETs, barely enough braking power to
stop on level ground let alone a slope or a god forbid a slope with trailer.
 
The worst thing on the ET is when a novice ET driver goes down a slope in cruise control, then hits the break a bit thinking
it would slow down. The big surprise is that the old lady will speed up :)  as the drive motor gets shut off and there is no
plug braking or similar (on the GE models, I think the new Idea had it).

I am sure some of you are on the, EDMOND ELECTRIC COMPANY LTD. Battery powered Electric Lawn Tractors mailing list and if you are you will know that the electric lawn tractor kit is scheduled shipping in May 2007.

But if your not here the news and the URL

http://www.electriclawntractor.com/   EDMOND ELECTRIC COMPANY LTD is now taking orders for their Electric Tractor Kit. Not bad timing considering the UN report on Global Warming

 

I am go to get one of these kits and convert a Cub Cadet which I?ve had waiting in the wings for about a year.  I might just have to start a blog and track the conversion.  Stay tuned.
