I spoke to a gentlemen whom did make a true hybrid ET. He was able to procure a 36-50v DC generator that was surplus telephone company equipment. Said that they were used to charge the batteries in cell phone towers? He said it put out enough amps to run the tractor all day long. I have looked and have not found a generator like this. I am going to shoot him and e-mail and see if he can enlighten me some more... > From: elec-trak-request cosmos phy tufts edu > Subject: Elec-trak Digest, Vol 9, Issue 7 > To: elec-trak cosmos phy tufts edu > Date: Fri, 14 Jan 2011 11:47:01 -0500 > > Send Elec-trak mailing list submissions to > elec-trak cosmos phy tufts edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://cosmos.phy.tufts.edu/mailman/listinfo.cgi/elec-trak > or, via email, send a message with subject or body 'help' to > elec-trak-request cosmos phy tufts edu > > You can reach the person managing the list at > elec-trak-owner cosmos phy tufts edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Elec-trak digest..." > > > Today's Topics: > > 1.

I don?t have much room to store a walk behind, I barely have room for the ET. Which is why I was thinking, instead of spending $500-600 on a walkbehind, if I could get a generator powerful enough to run the snow thrower (maybe hooked directly), and leave the batteries to move the tractor, for the same price it would be nice. > > Just wanted to see if anyone had tried it. > > From: William Martin [mailto:martinsprinklerdesign yahoo com] > Sent: Friday, January 14, 2011 11:43 AM > To: Banks, Michael J.; elec-trak cosmos phy tufts edu > Subject: Re: (ET) Hybrid Electrak? > > 1.5 to 2 hours is probably about all you'll get out of your batteries running the snow thrower as hard as you're running it. Everything sounds normal to me, given the conditions. I don't think these machines were designed for that heavy of snow work. I have a gas powered walk behind snow blower as a backup if I ever get a really nasty snow. That wouldn't be a bad idea for you. Probably more cost effective also. > > That's my 2 cents! > > Billy > > -------------- next part -------------- > An HTML attachment was scrubbed... > URL: <http://cosmos.phy.tufts.edu/mhonarc/elec-trak/attachments/20110114/3c7d8a64/attachment.html> > > ------------------------------ > > _______________________________________________ > Elec-trak mailing list > Elec-trak cosmos phy tufts edu > https://cosmos.phy.tufts.edu/mailman/listinfo.cgi/elec-trak > > > End of Elec-trak Digest, Vol 9, Issue 7 > *************************************** |
