Longer Bolts for rear Rockshaft bracket?

Tue Apr 23, 2013 6:22 am

I got all my parts over the weekend for the rear rockshaft unit and moldboard plow. Yesterday afternoon, I removed the belly mower, installed the rockshaft unit, plow, depth gauge and plowed the garden successfully. My only question is this; when installing the rockshaft bracket, the seat bracket has to be mounted in the same holes, so do I need to buy longer bolts? I was able to bet them tightened several turns and they all held fine, but I would think there would be longer bolts for the thicker base of the bracket and additional thickness of the seat bracket.

I would suggest to do so since you have added the extra weight and force of lifting the plow, you can never be too safe. I am assuming you are referring to the support brackets for a deluxe seat. Those 3 threaded holes on the top of the transmission housing for mounting the rear rockshaft are not open ended and do bottom out.

The bolt size used before mounting the seat brackets is 1/2-13 x 1 1/2.

Joe, my seat bolts on one cub without the rockshaft is 1¼" long. The Cub with a rockshaft is 1½" long

Forgot to mention that you will also have to shim up the opposing seat bracket with washers or spacers to make sure that you are sitting level after adding the rockshaft.

Thanks, I'll have to see if I can get the longer bolts somewhere local.

The seat isn't level now, but can't say it bothers me too much, but that could just be from the excitement of plowing with my cub for the first time. I was amazed at how well it cut through roots and turned good furrows. Going to plow a friends garden this evening and then switch over to the disc and harrow. Will then need to come up with a layoff plow of some sort.....probably a homemade deal. This tractor is so much more fun than the old Jubilee.
