akwells 08-01-2012 10:56:29 137.119.130.241 Report to Moderator	I'm running a 7' Hardee rotary brush cutter on my 1972 4020. When fully raised, the top rear of the deck is within 1/4" or so of the rear tires. Sitting still it just barely clears, but when moving it sways some side to side and actually rubs. I have the anti-sway blocks installed between the lower links. The tires are 18.8x34, practically new. Just wondering what adjustments I can make to keep the deck from hitting the back tires when its fully raised. Or if there is some way to limit the high point of travel. I don't particularly need to ride around with it jacked up that high anyway, but when I pull back on the lever to raise the bush hog, it would be nice to not have to turn around and watch to make sure its not going to hit the tires. Thanks for your time, I learn a lot on here. [Reply]   [No Email]

If set in "D" or minimum then rock shaft should start raising long before the end of travel of the RS control lever. If set in "D"(min.) then yes the L/D mechanism needs adjustment as outlined in a JD service manual. [Reply]  [No Email]

Can you weld new brackets to extend the existing on the mower to gain a couple inches? [Reply]  [No Email]

The tires are definitely 18.8x34. I shortened the top link as much as I could, and it did help some. It definitely changed the way it picks up, with the tail end now picking up before the front. I may play with it some more, but at the shortest setting and fully raised it appears to be about 3/4" off the tire. Still uncomfortably close, though. I like the idea of the stop on the console lever, but almost all the raising action takes place at almost the end of the travel of the lever. I guess it needs some adjusting. I may look into lengthening the lift arms soon as well. Thanks for the replies! If you have any other thoughts, I'll be watching. [Reply]  [No Email]

Toplink is not an issue because the mower is semi-mount (only mounts to lower arms) The only way I could use the mower on any of these tractors was with a quick hitch. Dunno why, but the arms are just too short. The quick coupler gets the mower out 3 or 4 inches and solves the problem. [Reply]  [No Email]

It will extend the bushhog out about 2 inch's on the end links and makes hooking things up alot easier when NO help is around. [Reply]  [No Email]

You could use one of these(parts key #12 R54533 STOP) although it's called a selective control stop but I think it will work. IIRC the slots are very similar in width. Or lengthen these lift arms [Reply]  [No Email]

I'll also try adjusting that top link. If my memory is right, I think the front of the deck does raise up before the rear. But I also have the wheel set fairly high so its hard to say. I am going to look hard at that top link. [Reply]  [No Email]

It sounds as though the front of the cutter is raising before the rear does. You want them both to come up at the same time or the rear to come up slightly quicker than the front.
