Mini bike cultivator

I combined an 8” hoss tools oscillating hoe with an electric mini bike

I combined an 8” hoss tools oscillating hoe with an electric mini bike. It is both fun to use and utilitarian. It is a one off and I am always happy when a google search doesn’t reveal anything similar.

This electric cultivator together with an electric tractor are the only power equipment I use to farm/ garden. My farm has had a 5.8 kW solar array for ten years and two powerwalls for a little over five years. My irrigation, refrigeration and home electric needs have been 88% solar powered for about decade . The solar and batteries have paid back the purchase price of my system . I still have grid supplied power but my electric bill averages about $30 a month .

I have been raising market pigs for the last decade and the solar system has supplied all the energy to keep my eight chest freezers operating. I will admit any transport of product or feed has been done with internal combustion . I am tired of feeding fossil fuels into trucking in a business that is not much better than break even. My farm has produced about a million dollars of pork but my days as a swineherd are dwindling.

I had a garden , a farm stand and a few years as a market gardener before the pigs came along. The pigs were initially intended to feed on all the vegetables that kept going into compost from the farm stand but they kinda took over. After a decade however I would like to restart my former vegetable stand with a goal to measure productivity of an electric farm.

How many calories can one farmer and electric tools produce? Just like my solar/ battery system paid back its purchase price with reduced electric bills how long does it take to produce enough vegetables to repay the cost of the new tools? If there is some way to calculate the embedded energy costs of producing the whole system of solar electrics and farm tools then how many food calories need to be produced to repay the embedded fossil fuel costs? These are valid questions and they have quantifiable answers.

I will be recording weights of vegetables and grains produced but farming entails cover cropping and soil building with legumes and added compost. These projects require energy and are necessary for healthy soils and productive crops. The energy expended for soil building can only be recouped with vegetables and grains produced but some accounting for the work required to maintain soil health is still necessary . Furthermore soil building and adding organics are one of the few ways we have at our access to pull atmospheric carbon back into the soil.

I do hope my project draws the attention of some agriculture college or other farmers interested in ag electrics. The tools are off the shelf available and I have a few acres to farm.

So zero fossil fuels for farm equipment, fertilizer, farm electric needs or irrigation and to the best of my abilities to avoid fossil fuel transport of production.
