Re: ET reliability (was: RE: (ET) [Fwd: Re: PICS of E20 with mowerinVirgina])



Really. I thought if you took an E20 from forward to reverse you would put serious strain on the contactors. I sometimes go into fwd while the tractor is moving backwards a little bit and it's a surge even with all resistors in place.

Larry,

I have an E20 and like to use it with cruisecontrol in forward.
My preferred way of stopping from cruisecontrol mode is to put it in reverse - it will coast to a stop. I am not quite
sure but I think all that happens when I would throw it in
reverse going full speed (instead of CC speed 4) is that it
also would coast to a stop.
If you want to apply power the other way to decellerate faster
without using the breaks I have to let of the accellerator pedal
first and reapply. I do this once in a while in case of an emergency, but try do avoid it as the current draw on the
batteries is so high and usually it spinns the wheels and
looses traction if I do that.
The thing I don't like about using the break for stopping is
that it doesn't allow me to coast from CC and depressing the
accellerator to turn CC off is "strange" and the (brief)
accelleration is the exact opposite of what I'd like to do.
Anyhow, point being is that you can throw an E20 into reverse
at full speed and don't hurt anything (I think), just don't
reapply the throttle. I think its pretty fool proof.

I believe the E-12S has the most forgiving electronics and is the most reliable. It isn't the fastest, or the most efficient, but it's the only tractor that you can put in reverse when going full forward that won't burn something up.

However this does bring up a point: Elec-Traks are not point and shoot tractors. They are not like the average Craftsman tractor which can basically be run with no maintenance till they fall apart in 7-8 years. In owning an Elec-Trak one sort of has to be able to do simple troubleshooting and some wire tracing/component replacement when needed. If nothing else, it's 30+ years old. And we're running them in production (well I am; mine needs to mow and blow reliably)

That said, the E12's and E10/8's are about as simple as one can find. In fact I'd have to say the E12 is about the most point and shoot Elec-Trak with the best bang for the buck. But even with an Altrax

and a Landis
one is still going to have to fiddle with the tractor to keep it running.

Is it worth it: Yes. Is it simple: Eh, depends. It's a bit harder without Bill, however I think the community here has filled

that gap.
Such is the way of things with any type of oddball, be it a Delorean, a Lotus, an electric car, or an electric tractor.

Hi Chris,

I thought I'd offer some perspective from one who is still very new to ETs and the whole concept of tractors in general. (If anyone had suggested to me a few years ago that I'd be driving a lawn tractor, I would have died
laughing.)

Like many, my New Idea tractor is not a hobby. It's a tool. I need it to work when I need it. I can't afford surprises, don't have the time. If I wasn't so pro-electric power, I might have considered a gas tractor. But then I read in Consumer Reports that garden tractors and riding mowers are among the most unreliable consumer products out there. Like most consumer products, they're not meant to be fixed by Joe Average. Since I don't own a
truck, that means service calls.  On weekends, the only time I have
available.  Very expensive, very inconvenient.

To me, an ET makes perfect sense even if you completely disregard the
environmental benefits.  It's built simply.  With a few basic tools, a
schematic, some sandpaper for the odd corroded contact, a hammer to whack
that sticking relay, some bubble gum here, baling wire there, a little
common sense or maybe a post here, it's rolling again. And when you take the time to fix it right, the chances are good that it will stay fixed.

Not that I've had to do so much as clean a contact yet. So far, the thing
just works.

I know most people think "real" tractors are gas powered. The reality I see
with my New Idea makes more sense.
