Does anyone have an opinion on the best position of their roller? I recently damaged mine and took it to the dealer for repair. When I got the mower, a 2003 Lazer Z XP, back the roller was on the lower of the two settings. I kept my eye on it for a while and noticed that it was getting loose and rattling around a lot sooner than usual. It looked like the roller was too far into the grass so I moved it back up. Is this lower setting for when your a mowing with the deck higher? I couldn't find much info on Exmark's website regarding the roller. I usually mow at 3.75 to 4.0. Also, My partner has a Skagg and when he is mowing on 3.0, I am on 4.0. It's the same height! Are these deck settings not relatively similar?? Doesn't the number represent inches? Thanks!!
