Electric Tractor Project Overview (Plan A)

    1967 David Brown 880 Selectamatic Can we make it an eTractor? Yes, we can (well, we will see 😃)  After completing other electric scooter projects (see Electric Joker ) I wanted to do something more challenging. Thought about converting a car, but there's way too many requirements to complete a road legal conversion. So, why not a tractor for use on our lifestyle block? Why did I choose a David Brown tractor for my Electric Tractor project? Mainly because I wanted a tractor that didn't rely on the petrol/diesel engine (ICE - internal combustion engine) to connect the front frame and wheels to the rest of the tractor. Looked around for a few potential options - Fergies and Fords were out, but David Browns seemed like a good option. Looking at the David Brown 880 my initial plan (Plan A) was:   The David Brown 880 picture below shows you the tractor and how the major engine and transmission components are laid out. And, the following gives an exploded view of thos

Electric Tractor Wiring Diagram

Still waiting on the timing belt pulleys to be machined (splines and minor machining), so in the meantime I've completed putting together my current wiring diagram:

Wiring diagram for David Brown 880 electric tractor conversion.

Jan 2023 Update: See my next It's Alive post, as I've now increased from 48V to 72V - above wiring is unchanged though.


Btw, the horn I built sounds like this:
