"This step is for mechanical lift equipped tractors only- To adjust MMM rockshaft lift strap (located between 3PH rockshaft and MMM rockshaft behind left rear wheel) you remove the mower and remove the hair pin clips and pins (D) to disconnect the lift links (E) from both lift arms. Raise the 3PH fully. Rotate mower cut height knob to lock position. Remove left rear wheel. (You might be able to skip this if you can reach the 3 bolts on the lifting strap.) Loosen the three bolts on the lift strap. Rotate mid mount rockshaft (B) forward until there is a small gap (A) between the the height cam (C) and mid mount rockshaft (B). Move lift strap forward to the end of travel slot and tighten the three bolts. (I'd use 1/16" to 1/8" for a goal for this gap.) Reinstall left rear wheel and mower. "
"First you want to adjust the side lift links (E) for maximum lift. To do this you'll want to start the tractor and raise the mower all the way. Rotate the mower height adjustment knob to the lock position. Now look at the mower height cam (C) above the left rear mower latch. It's just behind the left rear tire. You want to see a gap at "A". I've found that a gap of about 1/8" is perfect"
Both these procedure were written by Deisel shadow. I dont have gap A in my tractor. I want to increase it to 1/8th inches.
Where I am confused is what is the first procedure for ?
My understanding is that the second procedure is for increasing gap A? What is the first process for ?
I have Mechanical lift.
Thank you guys for help.
