I mow several sports fields for my counties American Youth Soccer Organization. Recently I have been asked to estimate aeration and over seeding. I don't own an aerator and am going crazy looking through posts trying to decide the best route to go. I can not afford a dedicated unit at this time so I need a ztr attached aerator. I would like something that would also be useful for residential lawns. I have looked in to Jrco and Zrator. Does anyone have any suggestions? I would like to spend no more than 2500$.
