i was practicing today on a 3 acre lot for a friend of the family to gain experience on my new ztrn. These things are a pain in the ass. I was making some pretty nice size divits. Any pointers on keeping the lawn nice. I talked to the dealer and he said to make sure that you have equal reverse to equal forward to prevent divits; and it didnt seem to work well. How do ya'll do it with out cutting the grass.
