Has anyone ever used one of these? Back in the 80's when I worked on a university campus, we used an Olathe (sp?) sweeper. It was about 50-60 in wide, maybe more, had a big rear hopper. It had three wheels with the single front wheel being the drive wheel. it was hydrostat. controled by a foot pedel and had a steering wheel that could turn the front wheel almost 180 deg for very tight turns. kind of like the Swiser BigMOw mowers. We dumped the leafs in piles to be picket up or into a low trailer with high screen sides. I remember this machine did a great job and could get into some tight ares despite it's size. I have also seen these towed by a tractor. Do you think something like this could be useful in our biz? I don't even know if they are still made or what the price might be.
