Has anyone tried to rig up an aerator attachment to their walkbehind? I'd love to be able to attach a Trac Vac 48 to the front of mine. Spoke to a guy at Trac Vac, he said no-way! I didn't ask why, wish I did. I bet it could be done by the right person. I also thought about attaching a pull behind Turfco 42 which should be easy enough, but I'm afraid I might fall down and aerate myself, ouch. Thanks.
