Okay, mowing experts, I need some help. John Deere 455 garden tractor. I refinished my 60" deck this Spring. 'Blasted it, painted it, and put new gator blades on it. When I set it back up, I was very careful in aligning the deck -- level side to side and about 1/8 lower in front. I am mowing a zoysia yard, and as some of you know, this is the time of year that zoysia starts getting really thick and beautiful. Everything I have read on the subject suggests keeping zoysia cut relatively low. The density of my turf encouraged me to set the deck just a little lower than I have been using -- probably 1-7/8" While I hadn't noticed it before, now it looks like I have an alignment problem on my deck. I have perceptible lines where the deck is cutting deeper in one spot. It wasn't very noticeable until a couple hours after I finished mowing. It almost looks like one spindle is lower than the other two. Is that possible? Or is it definitely side to side? The reason I am suspicious of one spindle is that the "short stripe" is almost perfectly level from side to side, as is the "tall stripe" I can't get to checking it out today, but I will tomorrow or Tuesday. Absolutely any thoughts on the problem are welcome.
