Picked up my 34z Friday great machine does a super job. Cut 4 lawns with it today and all 4 customers commented on what a nice job it did. There is no comparing my John Deer 110 lawn tractor. I cut through a foot of grass and it did not slow it down at all. I cant believe how fast it is definitely a learning curve driving a z compared to a lawn tractor.How long does it take to really get the hang of it?
