Can we see pictures of the the lawn of the unhappy customer.
What we do is we bought a x728 4wheel steer and have a track-vac that we pull behind it.
The extra suction from the vac picks up all most all of the thacth. It also holds a lot more than any badger on a mower. And we only do jobs that we can get into the yards with our equipment.
Works great for leaves as well.
