What About An Electric Power Trac?????

[ptx]

THANKS. I HAVE CHECKED IN EVRY ONCE IN A WHILE, JUST NEVER POSTED.
OUR PT180 ROBIN IS FITFUL AGAIN. LOVE THE TRACTOR, HATE THE ROBIN ENGINE.

THAT IS WHAT MOTIVATED ME TO CONSIDER AN ELECTRIC DRIVE. I HAVE AN ELECTRIC CAR, ELECTRIC CHAINSAW, ELECTRIC ROTO TILLER. THE TRACTOR IS NEXT.

Well, its gonna be a while on this thread. You responded to a 9 year old thread by a poster who hasn't been around for about 3 years. Maybe someone else will chime in, but its been a dormant topic for quite a while. Sounds like you have confidence in electric.

If you are doing this, I would use 4 electric motors on the wheels (or possibly one at each end and a "normal" axle), one motor for the hydraulic pump and install an electric motor on the implement for things powered by the hydraulic PTO.
Hydraulics are only 80% efficient, why take a 20% loss in performance in something you will run a lot pulling a lot of power (ie: wheel drive motors and implement motors).
I might add another motor to run the PTO pump for things that are more limited in runtime (ie: a posthole digger).

ANY SUGGESTIONS FOR A PROBLEMATIC ROBIN 18 HP EH65?

THE ENGINE IS ABOUT 10 YEARS OLD NOW AND WE HAVE WORKED IT HARD.

I JUST CHECKED THE COMPRESSION , 130 ON THE LEFT SIDE 140 ON THE RIGHT. THE ENGINE STARTS IDLES NICE,
BUT NO POWER. REPLACED THE PLUGS, NEW AIR FILTER NEW FUEL FILTER.
WE ONLY USE ALCOHOL FREE GAS AND RUN THE FUEL THRU A RACON FILTER WHEN FILLING.

Someone just swapped in a predator engine from harbor freight on a PT422, I think.

Here's a link to that discussion....

It may work but why bother!! Great philosophy fourteen. How inspiring.

Fourteen is right. - Ridiculous at this point of technology for a general use working vehicle platform. Niche use in a barn is fine because not much work is done. By contrast to just rolling around, use under the constant loading inherent in general tasks of notable duration done outside will be unsupportable without a very expensive lithium battery.

Interesting discussion about electric Power Trac a few years back.

 

[MossRoad]

Yep. Lots of good discussion from lots of members that I miss talking to. Hope they are all doing well. :thumbsup:

The energy density in batteries is about 4% of that in gasoline, and I think that is optimistic. As such when you build an electric vehicle you have to minimize the energy use in every component. Power Tracs do not presently do this by any stretch of the imagination.
