When I was driving my Jeep most of the time, I could easily stick a hand out the window and drag the can down alongside to retrieve the can. The benefits of a vehicle that has no curves on the side! With my F-250 I can't do that any more.
My driveway is 342' long and mostly flat. I have used the tractor a time or two when the can was super loaded, but not on a regular basis. I just had the driveway paved over the summer, so now garbage night is no big deal! Sure is easy rolling those cans on blacktop!
