About 2 seasons ago we invested in a cultivating tractor. We had been doing all of our weeding by hand, but we started to get behind a lot of the time, and were looking to expand our growing space. We knew that there were a lot of options out there- Farmall made some good ol’ cultivating tractors as well as Allis Chalmers. (There are many others too, but these two seem to be the most readily available these days) One thing we knew about cultivating tractors was they were generally gas powered as opposed to diesel. This equates to less power, the inability to run biodiesel, and just the same standard chugg-a-lug of old tractor motors.
During the investigation of what tractor to look for, I came across a great resource for converting an old Allis Chalmers G from gas to electric. That’s right- 48 volts DC!
So I started the hunt for an old AC G with no motor. Came across one outside of Corvallis, Oregon. Bought it for $800 and then spent another $2500 on the motor, batteries, and other parts for the conversion.
Over the next 2 months I stripped the tractor down to parts, refurbished anything that needed repaired, and then put it back together and added the electric components.




The next question was deciding what cultivating setup to use. I talked to several other farmers to see what they used and consulted the book “Steel in the Field” and came to the conclusion that a basket weeder was the way to go. The basket weeder works great in lighter soils- loams, sand, silt- but does have some limitations in heavier rocky soils. The basket weeder also works best when weeds are at the white hair stage. In other words when the weeds are still just emerging. If you have an established stand of grasses or other weeds then a tool bar with sweeps might be a better bet. (I’m setting such a tool bar up this season and will post about it once it’s finished.)
So check out the video of the basket weeder in action and listen to the quiet purrrrr of the electric motor. Another thing you might notice is the tank mounted on the back of the tractor’s battery box. This is used to spray fish fertilizer as I weed. It runs off it’s own separate 12 volt battery. This way I can cultivate and fertilize in one pass. Any other questions about the tractor and it’s conversion just email me.
