We are considering the purchase of a tractor with attachments...such as an aerator,vicon spreader with boom sprayer. Can anyone give me information on type of aerator to consider along with a company we can go to for all of these attachments. We currently run Z-Sprays and are very happy with them, however, we are looking to cover more sq. footage with a piece of equipment that can be used all season long. Any advice would be greatly appreciated.
