Jerry I designed and built many electric tugs from 1990 thru 2006 when I sold my company. Most of my designs were for aircraft tugs. I had a line of tugs for moving trailers. Pull type campers and fifth wheel campers. The camper dealers would use them to move trailers in and out of the shop and parking displays. I used permanent magnet motors. Usually with a one to three hp motor. A small winch motor could move a large load. I'm assuming you are going to run the motor thru the transaxle on the tractor. With that gear reduction you won't go very fast but will be able to pull a large load. You would probably want to run a 24v system. The motor could be a 12 to 24 volt unit. You could rob an old golf cart controller. Be sure to get the pot for it also. When using a riding lawn mower for the chassis, keep the hitch for the trailer as close to the centerline of the rear axle as possible. Keep the batteries up front where the gas engine was. Maybe you can keep the front wheels on the ground. Use deep cycle batteries, not car batteries. This shouldn't be a very difficult project and a fun way to get your feet wet in an electric vehicle. Let me know if I can be of assistance. Dwain Swick kansasev.com,

I've tried to search the archive but could not find what I'm looking for. What I really need is something to move small utility trailers around a city lot. My dad is getting older and doesn't like to move things via wheelbarrow and using a trailer dolly and pushing is getting hard. We have a ridding mower with a blown engine and it looks easy (from a mechanical point of view) to rip out the engine and the mower deck and replace it with an electric motor. The motor would just need to be mounted vertical and have a v-belt pulley mounted on the bottom. However I do not have any real experience with electric motors. The bits I need help on are what motor to buy, how to control the speed and a charger if it is something other than 12V. The run time at the bare minimum only needs to be a few minutes per charge. The use would be pulling a small trailer of fire wood around to the back of the house with a slight up-hill slope. A secondary use (phase 2 if you will) would be pulling the same trailer around a 5 acre lot and would need longer run times and the ability to climb a hill. However this 5 acre site has a farm tractor so this really isn't much of a design concern. However if I could, for example, get by with one battery at the city lot and add two or 3 more batteries for the country lot that would be nice.
