Forklift is massive overkill for your application. Something likecan etek, at around 15kW is lighter and won't tear up your belts.

What exactly does this tractor do? I don't see a PTO or hydraulics. Every belly mower deck I've seen uses V-belts.

Cricketo's motor will not work. Don't understand the 48V battery, though - you said 3600RPM.

edit: that's a pump motor rated at 20% duty cycle. No good for a traction motor.

Motorize the roller 😂

You crank the voltage up to get more speed (horsepower) and push more current.

etek...

Hey Floyd - what model number on the motor?

 

[remy_martian]

I don't understand why you need so much power to tow a roller. Is it round or rectangular? Towing at 30MPH?

More than 4 or 5 kW on a reduction chain/belt will just spin the tires.

But you aren't running any implements off the PTO...

That 12HP ran a PTO for things like a mower deck and provided traction power. He is not running implements, so the gas equivalent is no more than my 3HP minibike was to move rider and tractor.

Now add in the rolling resistance of a roller and his harrows and he's at around 5-6HP GAS engined.

Thanks for all the advice. I can get the pump motor for $100 or the 11" drive motor for $200. Both out of an old Clark EC500 forklift. I'm tempted to go with the big one but I'm afraid the RPMs will be pretty low at 48v.

What do you need RPM for?

"It would be nice" gets very expensive in electric conversions
