Although exercise is good, my body is physically unable to take the pounding of muscling around walk behind aerators and seeding equipment. I figure anything good for me would also be good for my guys moral, bodies and productivity too. I own a PG spreader and would like easy to handle equipment capable of getting through the same small areas as the PG, ie: 36" openings for the most part. I know there have or are aerators for the front of Walker mowers and another one I saw here a year or 2 ago for the front of ztr mowers that raises and lowers. I already own a split drive aerator, 48" tow behind aerator and Ryan Mataway slit seeder. I want easier, less physical, operation that produces a quality job. A "seeding system" with a power unit of a 36" hydro walk behind with removable 1. core aerator, 2. slit seeder (drop would do like blue bird) and 3. s tined wheel rake like a hay rake to move the resultant debris quickly would be great. Put it on a Walker or equivilent riding piece, better yet. What do you guys know or what have you built?
