I have a Sears front wheel drive lawn mower, 21 inch 6.75HP, model #
917376551, that is about 6 years old. Today while mowing, when I
engaged the front wheels by squeezing the lever on the handle, I
something “POP” and then the wheels froze up. The drive wheels had
been making a “slipping- as if a gear inside wheels was slipping and
then re-engaging” noise periodically for the past few months. I took
the plastic cover off the drive assembly area and the cable from the
handle lever is not broke, it stills seems to move the lever that is
attached to what appears to be a gear box. Both wheels are frozen and
will not turn by hand. I read some of the previous posts in the
but still getting educated on mower repair. Any ideas on further
troubleshooting to see 1) what problem might be 2) is it something I
could repair(reasonably handy) 3) not cost effective to repair 4) or
any other things I failed to think of ? thanks in advance for your

Only a couple of things I know of. 1st, is something you probably would've
noticed with the drive cover off, the drive belt came off the transmission
pulley and got jammed under the pulley and then possibly also jammed in the belt
retainer above the blade (not the lock-up cause from there though).
And 2nd, is that you need a new transmission. I've actually never had a
transmission go bad, but I also stopped buying Sears or Craftsman mowers because
they turned to crap design. The lock-up wouldn't have anything to do with the
Traction Cable, Drive Belt itself nor any springs.
It may be very tedious, but you can tackle it. Some Craftsman mowers have a
whole Drive Tray (of stupidity) that has to be completely removed and fully
disassembled to get the old out and new in, for probably the same extremely poor
