Conversion TimeInitial test conversion was one afternoon.
Final conversion is on going, but took about 32 hours.
Conversion Costinitial conversion was around $200 with used batteries
Final conversion will be around $1,000-$1,200 with new batteries and all other new components.
Additional FeaturesI have been adding work benches to the hoods of my garden tractors. Very handy to have. I have 120 VAC power wherever I have my tractor.
This conversion could have stayed very inexpensive, and that is why I like it so much. It is not the best conversion, and is not the most efficient, but it is very functional. I built my house using this tractor to power all of the tools. I use an electric chainsaw and trimmer on this tractor at least once a week year round, and I converted an old tiller to electric as well and use that in the spring. Very reliable, and because I used stock components anything that breaks can be repaired or replaced in very little time. The switch in the motor from the buffer or grinder to a heavy duty treadmill motor was a vast improvement.
