Also, the shaft is 5/8" diameter and the original dual pulleys are for a 1" shaft. I am trying to figure out how I can mate these things,........

{local metal shop get steel tubing 5/8" I.D that is also 1" O.D.}

or should I do some engineering to make use of the sprocket? i.e.: mod the system to accept a chain drive?

Chain drive on lawn mower would be suicide No way to move it across yard or onto trailer without blades turning.

My pot switch will be connected to the existing throttle cable. My unit only has a clutch/brake pedal and Wife allready knows how to operate the previously I.C.E. equipment.

update.....
My older batteries that I had laying around will not work for me. I charged them all to 12 volt and hooked up three of them to test sytem. System pwered up real well. Voltage drop from 38.5 on full charge to 18.5 within a couple of minutes. Turn off motor and I am back to near 28 volts. That is unacceptable for me.

Time to hit up Interstate for some new batteries.

Great Job... i've taken on a project..first one.. to convert a friend's.. he's tuning his up twice a year..and has had enough.

I'm leaning towards lift truck pump motor at 24 Volts...

So do you think the non-controller method is causing you battery woes?? Sounds like a real dollar winner for this project..

Intersted to know where you would spend 200 dollars on batteries and your thoughts on the 24 volt Lift Truck motor.

Alex:
Could very well be. I do know that my batteries are very weak and I am going to use brand new better quality wiring when my controller gets here, just for now, everything is in the testing stage.

Alex:
24 volt lift truck motor (depending on model) is probably much more substantial than a club car motor. Golf carts weigh 600-1000 lbs. Fork lifts weigh 2400 lbs and up. As long as you can attain 3500-4000 R.P.M.s, it should do fine. For a 24 volt system you could easilly buy two good quality deep cycle batteries for yours with that amount of money. Depending on availiability, You may want to consider four, six volt batteries. Plenty of room to store them, better performance (from what I have read here) and longer run time. Check out the battery threads here and you can get a better picture than what I can portray.

I tried an experiment... I used one of those tools that you use to flange a copper pipe, cos it's basically the same action as a gear puller. Miracle of miracles, it worked! I successfully pulled the sprocket without having to destroy it! Too bad I have to go out of town for two days, cos I could have worked on my project instead. Well, there is always the weekend...

Any updates on this project?

[Alex Everett]

An injury has me sidelined for the next week or so. I am not allowed outside (Warden Wife won't let me) by Drs. orders. Have all the brand new 2 guage wires, 48 volt dash meter, 48 volt solenoid and 48 volt controller. Pot switch is on the way but have not picked up the batteries yet

I am looking to build an electronic version of my craftsman yard tractor. I am curious to find out how you did and if you can help me get started. Very much the newbie here.

I agree, do leave us hanging!, how did this work out? Any others out there with working EV mowers?
