I thought I post how well my Ecolawn has held up and give anyone pointers on things to watch out for. If anyone else has any feedback feel free to post up. At the very first yard we ever top dressed the allen head bolt that holds a key in place backed out and the key fell out of the pulley wheel into the lawn. WE got super lucky and were able to find the key which is like trying to find a needle in a haystack. The allen head bolts should really have Loctite on them since the machine vibrates a lot by design.
