This will be a strange question. But, about every day I drive my tractor and manure spreader around my pastures to pick up piles of horse manure. For you non-horse folks, horses produce a lot of manure piles in a day. Picking it up regularly is probably the best way to control gastrointestinal parasites and flies. So, it's drive to a pile-get off the tractor-shovel the pile into the wagon-climb back on the tractor-drive to the next pile-and repeat probably 50 times. Sometimes I just operate the tractor pedals with my hand as I walk beside the tractor from pile to pile; I know it's risky.
I find myself wishing that there was a way to just have the tractor follow me around like a dog on a leash. So I did a search to see if there were such things as electric vehicles big enough to pull a small trailer around. The only thing I have found so far is a golf club cart.
My question for you innovative and technologically knowledgable folks is whether you know of a small tractor-like vehicle like this?
