Mowing rear mower questions

What I did was put a book under the rear of the monitor so the screen was tilted so I could see the screen in focus. Wife could not believe that I tilted the screen, she thinks it will tip over, guess I need a tip meter after all!!

2 points.

On topic, make these adjustments on a smooth, level surface, like your driveway. First, loosen the deck's back wheel, probably have to simply remove the bolt. Second, set the 3PH control down so the front of the cutter is 2" above the height you want your grass to be cut. Third, set the upper control link so the deck is level. Fourth, set the back wheel so it is just supporting the back. Fifth/sixth, lower the 3PH and adjust the top-link so that the front of the mower is at the height you want your grass cut.

That process should leave you with the 3PH still supporting the mower in front, the rear wheel supporting the back an inch or two higher, and your ground un-scalped /w3tcompact/icons/smile.gif. The important thing to remember with the cutter is that you never use float... that'll just let the front dig into the ground with a cutter, unlike with a finish mower. With a finish mower the 3PH is in float and the front and rear rollers/wheels keep the deck set properly.

Off topic, my optometrist told me that in NY they are allowed to produce a second pair of glasses w/o a prescription that is the average of the bifocal's prescription. She said that is what they do for a lot of people who need "computer" glasses. It took me a month or so, but I finally got the hang of my bifocals, so I never went that route /w3tcompact/icons/smile.gif.

Thanks all for the good advice.

Markcg2000,
On your fifth/sixth step, are you saying to lower the 3PH all the way as low as it gets and it stays that way when you mow? By floating, you mean the 3PH is raised to some cutting height? I was trying to control cutting hieght by raising and lowering the 3PH. But I think it would slowly sink down then the front would dig in. I was constantly trying to adjust the lever.

Several others here have hit the nail on the head. The trick to adjusting the rotary cutter is in the top link. I use a 4 ft. bush hog on a B7100 and basically the top link has to "push" the front of the cutter up. You can still adjust the cutter to have the front lower than the rear of the deck by using the top link and then adjusting the rear wheel to gain proper height for the back of the deck. Takes a few minutes on a level surface, but once adjusted you shouldn't have to mess with the rear wheel again. I wrote the top link length on the bush hog 3-pt frame so I can easily adjust the link each time I hook up (use a permanant marker). Just back in, hook on, measure the top link and go. Once adjusted, you can just lower the rotary cutter and not have to try and adjust the upward/downward positioning with the hydraulics.
