I have a Craftsman self-propelled mower that recently has problems.
After I engage the self-propel mechanism, the front wheels turn but
after going a few yards (distance varies) they stop turning. If I
disengage the mechanism and then re-engage it, they turn again. I've
checked the engaging line and it looks OK.

Any ideas what the problem might be and how to solve?

Thanks for all help.

Addition:

The wheel and shaft assembly could also be worn bad enough that the
amount of slop could overtake the engagement distance that the drive
needs to work properly.

My new Craftsman variable self-propelled has a belt drive where there
is an adjustment screw that determines how tight the belt is. If
yours is similar, may need adjusting.
