It is a Hasty Lawn Vac model 3660. Has 9 bushel capacity. Can put garbage bags in containers for easy leaf or grass removal, if local garbage pick-up requires you to in your area. It is a one piece unit you just put on your zero turn mower. I take apart in pieces so I can handle putting on and off mower by myself though. Has a 5.5 briggs and stratton intek motor that drives the vac itself. Does a great job. I used it on a Super-Z, had new rear top angled piece for mower made so i didn't have to drill holes in original rear end. Will be selling that too if someone needs it, made of 3/8 steel instead of 3/16. Will try to post some pics if someone is interested.Asking $1000, negotiable if picked up and not shipped.
