    Ideas for EV farm machinery

    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. https://www.avanttecno.com/global/machines/e-series

    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 :(

    Ideas for EV farm machinery

    Yes. Approximate weight-to-power ratio is about 50 kg per 1 horsepower for light tractors. And two more pictures: (A 8-share plough dragged by an electric winch was on trials in 1921 near Moscow. 20 sets were made for collective farms. A plough crew consisted of five men: one on the plow, two...

    Ideas for EV farm machinery

    Yes, colour photos were rare, used in magazine articles that had a big role in propaganda. And from 1960 to about 1965 a "small" nuclear power plant produced some electric energy in Obninsk. It was based on 4 tracked self-propelled stretched chassies of a heavy tank. Its electric power was 1500...

    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...

    Raised Bed Gardening - Cement Blocks > Greenhouse!

    I did not know anything about community gardening in other countries before I read this topic. (In my country there are such things as dachas, but this is another matter) I assume that you live in the country where agriculture is really great and excellent and I just wonder why you buy seeds...

    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...

    eZee motor and controller at 69 amp phase?

    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.)

    2 speed gearbox/jackshaft

    Does your gearbox have two separated shafts - input and output?

    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?
