If your machine's serial no. is less than 210000, remove the right-side rear wheel, remove the cap screws that go through the bracket. You shouldn't have to remove the nut in the center of the bracket, but if you do watch for a small spring and two pins to fall out, so don't do this over a grass or dirt area. You're there.

Things vary among serial numbers and whether you have a black deck or a yellow deck.

Thanks. Appreciate the feedback. I'm new to this so I thought I had signed up for the e-mail. I'll have to go back and see if I can't change it.
How hard is it to remove the rear wheel? Does it require a puller?

Thanks.

Not difficult. Remove the plastic cap, then snap the e-ring off (do this over a paved area, 'cause it's small and likely to get away), slip the washer off, and pull the wheel off. The wheel COULD be frozen to the shaft, in which case you might need to spray it with P-Blaster, let it soak in, tap wheel with rubber mallet. When you put it back on, apply never-seize.
