For reference, this is a 2015 Gen 1 2025R with 62D MMM deck and independent lift.
For those of you who have not liked the lack of mowing height control on your machine, I was able to get about 3/4" more lift for $20. The problem being that in the full up locked position, the deck is at about 5 or 6 inches. The first, and highest setting only equated to about a 3 inch mowing height. I wanted to see if I could gain any by altering the deck eye bolt and yoke to gain some height to help my lawn be a little more healthy and look a little better.
The problem with the adjustment yoke on the lift arms is that the bolt it screws to is not fully threaded. If you try to screw the yoke on as far as it will go, the bolt dead ends into the lift arm.
I fixed this problem by buying two new lift eye bolts at just over $10 each. I threaded them with a 3/8 x 24 die to the full length, and cut off one inch from the end of the bolt.
Once completed and installed, I gained about 3/4" of mowing height. Easy and inexpensive.
When finished, be sure your hydraulic hose is routed clearly from the lift stop on the mower deck (see last pic).
Edit: sorry the pics dont show in the order I uploaded them, makes it a little confusing, but you should be able to figure it out.
