MMM Cutting height

[Anonymous Poster]

I have a 4310 with 60" MMM. I bought the John Deere leveling and cutting height gauge. The deck is level and I wanted to set a cutting height. The gauge wheels are setup for 2 1/2 inch cut. I turned out the height knob and lowered the deck until the blade tip measured 2 1/2. I thightened the height knob. I cut a path and thought it was much too low. I raised the deck and reset the knob. I did this a couple times till I thought it was cutting at the height I wanted. When I got back to the garage I used the gauge and found I was cutting at 4 inches. I measured from the floor to the cutting tip of the blade with the blade side to side.

I know I will cut at what ever height looks right but don't most say to cut at about 2 1/2 to 3 inches. I'm at 4 inches now and I think it is borderline low. By the way. What unit of measure is the other measure on the gauge? I see numbers like 51.

I try to keep the height near 3", but it can depend on the type of grass. It really depends on what YOU like, as long as you don't go too short, as that will burn the grass.

As far as the "51", I would think it would be a measurement in Millimeters. Is it near the 2" mark? 25.4 m.m. is equal to 1 inch, therefore the 51 would be at the approx. 2" mark (50.8 m.m.)

I personally keep my 60"mmm set at 3". When I had a GT235, I kept the deck set at 2 1/2 inches, but I read that 3" keeps the grass a little healthier.
As mentioned earlier, it really is a personal preference issue. I personally think my grass looks nicer now that I mow it a little higher, but I do have to mow a little more often to keep it looking well groomed.

Apparently I cut mine really high. I have kentucky 31, and if I cut it any lower thatn 3 1/2" the large clumps of grass look like a really short flat top. It is also looks discolored because it is so short. 4" really makes my yard look full and fill in the few bare spots I have in my yard.
