Yes, a BEV tractor may be practical for a Hobby/Garden farm, light duties, etc
Yes. Just for example, Avant produces mini-loaders e5 (11 kWh battery) and e6 (13 kWh) for indoor use at livestock farms. Advantages are no emissions, low noise.

Re: Ideas for EV farm machinery

Obviously,
given the energy consumption of, let's say, 30 kWh per 1 ha, the battery-powered tractor will need to squeeze out 1 Tesla battery per 3 ha :(

Re: Ideas for EV farm machinery

When you said cable tractors I thought you meant a stationary engine with a damn big winch dragging a plough back and forth across a field. An electric tractor plugged into a damn big extension lead probably makes more sense but winch ploughing would probably be more cost effective and there probab...

Re: Ideas for EV farm machinery

In the former USSR The Agriculture Electrification Institute did some tests and trials with cable tractors from 1949 to 1950s. Tractors had a 3phase 42 kW induction motor and pulled a 5-shear plough. Average power consumption was 45 kW*h per 1 hectare. Operational and capital costs for the electrics...

Re: electric vs gas theory

So we can say that locomotives and ships that have electric transmissions were first hybrid electric vehicles. As for railway histories, in USSR the Fairbanks-Morse Model 38D-8-1/8 was 'reverse-engineered' in the late 1940s to the Model 2D100 diesel and long lived as a prime mover of TE-3 freight lo...

Thanks Dr.Electric.
(I would like to install that motor into a 20' wheel but a strong non-folding frame for 20' wheels is a hard-to-find item at my location.)

Re: 2 speed gearbox/jackshaft

Interesting.
But maximum input torque is 40 N*m, so maximum output should be 80 N*m. Is it capable for about 50 N*m input and 100 N*m output?
How to link a motor to the gearbox?

Uilleam Gilvoni What sprockets (front and rear T] did you use when climbing? And about what speed or motor' RPM?
