The Raptor that I bought and happily returned for a refund...did not cut as well as the Troy-Built lawn tractor I traded in for it...and the lil stump I hit that bent the deck mounts...my Troy-Built would have been able to absorb the impact because there was some play in the deck mounts it would give a little instead of bending the deck mounts like the Raptor did.
Based on this thread, I keep second guessing my Raptor SD purchase, that is until I cut my grass again. I have not yet been able to cut it when it is dry, it has rained so much and growing so fast, if there is a few hour break in the rain I cut it. Just finished cutting about an inch that has grown in 4 days. Grass was wet, ground was soft. The only time I noticed any clumping was when I put it in reverse (no idea why this would happen since the blades still turn the same way). I quickly drove over the clump and it was gone (I do have the mulch kit). I am the only one in the neighborhood who cuts their own lawn and it looks every bit as good as any professionally cut lawn. I am also the only one who seems to fertilize so actually it looks better. Could not be happier with the SD.
I do have a problem and I think it is related to ZTM in general and it has to do with turning at the end of a run. I am putting a nice divot at the end of each line I cut (OK, the professional cut lawns do not have this, so in that case they look better) I know it is technique, but not sure what I am doing wrong. Any suggestions?
