The Craftsman walk behind
mower developed a slight wobble last year and my short cut solution was
to add a couple of large flat washers to fill in the space where the
plastic was broken.
Turns out it was not such a
great idea. The wobble got a little bit worse each time I used it and
for some reason I got stuck on upgrading both rear wheels to a more
sturdy pneumatic version and forgot the simple route of looking up the
part number and ordering the original wheel from Sears.
It's hard enough to push this
thing through heavy grass and weeds and over uneven terrain without
making it harder with a wheel that wobbles. Take my advice and replace
a wobbly wheel sooner than later. Our Craftsman walk behind mulching
mower rear wheel part number ended up being 151155 and after shipping
it cost about the same as an engine
cable.
Update:I got the part number wrong-It's 189159 and it comes with 2 metal bearings.
