It's an E-tractor the motor has died (24 volt series wound golf cart motor) after serving us well for 10 years.
It is almost impossible to find another used motor out of a golf cart or equal because the newer ones all bolt up to the differential thus do not need a bearing on the output end, the tractor is belt drive.
I have a motor out of a treadmill currently being used on a large sander I use for woodwork. (20" X 118" belt) it has almost twice the power of the current motor but needs about 80 volts, I can replace it with a slightly smaller treadmill motor. Have to keep costs at a minimum as we are on a fixed income and building a house.
Am planning to build an 80 Volt +/- leaf module battery to drive the treadmill motor, anyone have advice or opinions???
Some pics:

Cool build I believe I saw your tractor on another forum or maybe another almost like it. my folks have a couple dead lawnmower tractors sitting around. Dammit just what I need another project! :)The forklift mast on the front end is great. I saw a treadmill on the sidewalk on my walk today.
Replacing the LA batteries with leaf cells I suspect you will have to off set the weight difference by adding weights to the rear. What size is the treadmill motor?
Sounds like a cool project.
On your E tractor is it direct drive or does it use the original tractor transmission? What controller did you use? So many questions grrr :) guess I will add it to list.

Later floyd

Floyd, grab the treadmill, amazing what you can do with the parts.
The tm motor I have is about 4 hp at 90 Volts with a max draw of 25 amps.
I will use a pwm to control the speed. The tractor has a 6 speed transmission with reverse, and for the series motor used a Curtis speed control with potentiometer linked to a foot pedal, hope that the PWM will accept the old pot.
Those pics are at least 5 yrs old, the forklift weight tore up the steering gear so we put in hydraulic steering. Also added a sun/rain shade in the form of a 300 watt 32 volt PV panel, so untill I fried the batteries did not plug in the tractor for about 2 years. Has been a work horse for us, & hope we can keep it going, even tho' the heavy lifting is pretty much done.
