Electric SF video

Thats cool. How long you think it will run on a charge?

Cool that trans sounds sick!! is it dry?? nice job will the sheet metal fit or will you have to modify??

After I get new marine deep cycles it should run all day long on a single charge.

As for the trans, it was dry before I filled it up. It was quieter without oil I think... I didn't drive it out of the shop without oil if that's what you're asking.

Oh, and the original sheet metal will fit with no modifications required. Unfortunately the hood won't line up with the stock mounting holes, wonder why that is, gonna have to mess with it some.

THAT IS KEWELL!!! I'm reminded of a recent post where someone wanted to put a screamin 2 stroke on a certian Massey to make a lot of noise but not go anywhere. This is soooo much better!

no torque lol and this thing is called Power Wheels lol

Yeah want to see pics when its done looks good. What size motor is in it??

Where did you source the motor from?


I'd like to build an electric tractor for my boys.
I tried using a golf cart motor but the front motor bearing and mount is part of the rear diff housing.

Well, I stole the motor (250 Watt, about 1/3 hp) and throttle from a broken down electric scooter a friend gave me. Then I bought a controller, a key switch, and a circuit breaker from monsterscooterparts.com, and had them 3 days after payment, which they take Paypal. Now they also sell complete motor kits (motor, controller, and throttle) and the next one I build I will go with a larger motor set up. I did use chain drive on it (#25 scooter chain) and am very pleased with it. It took a while to locate a #25 sprocket with a keyway and it wasn't cheap, Bought the 20 tooth one for 3/4inch shaft for about 42 bucks shipped. It took 2 weeks for the sprocket to arrive from robotmarketplace.com. It wasn't a difficult build, just drilling holes in the original chassis... Also, for the throttle I used 3/4 inch copper tubing which is 7/8 inch OD for mounting the scooter throttle on. As for batteries I finally bought a pair of them today, which really made third gear, road terrain only. The batteries I bought were EverStart series 29 deep cycles from wall mart, price of them incuding core charge was $199.28, but well worth the money. I have a friend that goes boating every weekend with a pair of those batteries hooked to a pair of trolling motors in series. He claims he gets about 12-15 hours out of one charge, so should be good deal. My Uncle gave me a 24 volt 10 Amp Hour charger last year so that will be my charging method. My total investment up to this point to convert it to electric is about $300, but I utilized preused electrical parts that dad has accumulated over the years as an electrician, so that really cut my costs. Here are some links to the exact pages to buy the motor kits and sprockets.

instead hell buy a jap truck

Looks good so far. Better than it just sittin' in the tractor house collecting dust! Now you need to try it with a mower deck lol!

Alright guys, I have a new driving video with the new batteries on board. Check it out.

Sorry it's mostly batteries but it requires 2 hands to drive leaving no hands for the camera LOL.

And Evan, I have to swap the tranny out cause I need a good one now more than before. With the new batteries 3rd is too high of gearing for even the most gradual of grades and 1st is just too slow for anything more than a short hill climb lol.

Thats great looks good I would think about useing heavier guage wires on the battery though for the amprage draw.

I did go bigger than what's on the scooter, which is 14 gauge mostly, and I used 12 gauge wire in all I did. I have checked the wire temperature periodically and no wires are getting hot under long pulls uphill, so I figure it is good to go. Only part getting warm is the motor since I'm using its full RPMs most the time since I have no second, which after a tranny swap next month the problem will be fixed.

I was just watchin' your new vid a little bit ago. Looks good with the hood on, and I saw your other Springfield hood and grill sittin there. Also, looks like you got the Gravely out too.

The thing with driver weighs 500 pounds and now wont pull steep short hills without stalling, may have to upgrade the setup.

time to shed some weight. Start an exercise program, or see if you can make do with 1 battery.

24 volts, I need both batteries. Thinking of upgrading to the 900 watt motor kit ($150) but probably well worth it, requires a little modification to what I have already done on motor mounting, but I can set it up with my spare 4 speed unless I hold out for my future 3 speeds... Depends on my motivation level. But I will at least secure the kit before they are sold out.

get a 24 volt battery.
