I’ve finally decided to tackle my deck height problems on my 1025, 60d mechanical lift. . I cannot put the deck in the lock position. I have followed the sticky on this forum but I am still having problems. If I remove the deck I can put the control knob in the lock position but when I install the deck it will not go high enough and comes up 2 notches short on the control mechanism. I have the leveling arms as high as they go, but still no luck. Any ideas?
