Hello

I run a working stables. I have 55 stalls to muck out each day. Currently we load manure into two old Pick up trucks that haul to a dumpster. These trucks get started about 15-20 times a day and are moved a maximum of 0.5 miles. I would like to convert an old truck that no longer works to electric. I only need the truck to go a max speed of 15mph or less. What is the smallest motor I could use? what are the bare minimum components that I need? I think I only need a motor, batteries and a braking method. Let me know your thoughts.

Thanks

Well that's a shitty idea.

Smallest motor? A treadmill motor would probably be good enough, but they'll be higher voltage (90v+).

Honestly, if you got rid of the engine itself and somehow hooked the starter motor to the transmission, that might be enough, just running the starter. Leave it in first, maybe 2nd, and just go slow.

Throw a spare starter battery in parallel so it has some extra capacity, probably a fan on the starter to keep it cool. It might be enough.

Brakes should still work, they just won't be boosted, can you stop a manure truck from 15mph by stomping on the brake alone?

Speed control... is the gearing enough? You could just use a big resistor in a jug of water or nonconductive oil to slow start.

Alternatively you could use any electric hydraulic pump motor from a forklift or whatnot. They'll be 6-7" diameter, about 75-100 lbs. That'll be enough to hit 40mph and you could also dig out some crappy speed controller. A couple/three starter batteries in series is probably fine (24v? 36v?), as long as you keep them topped up without significant deep discharging.

You're on a farm so you surely have some left over industrial scraps around. Tell us what you might be able to re-use and we can probably suggest how to hack something together.

Awesome news! I am looking now and I found a go cart kit that runs 24V. I may try to use that or my son has a controller setup using an arduino. This is a big push to start this project. I will update when we start the project. Thanks again.
