NOW LETS GET TO BUSINESS, If you did not know, Sears works on the premise of Planned Obsolescence of parts (don’t be shy look it up).
NOW LETS FIND THE PARTS:
Find the Part Diagram of the mower.
From the diagram the HELICAL GEAR wears and the Worm Shaft gear wears stopping the front drive wheels from moving.
Goto the following website (http://www.outdoordistributors.com) and look up the part number AYP-133804 (Helical Gear) and you will see it is discontinued, however Part number AYP-137050 works for this repair (Replaces the following number(s) AYP-532137050 the cost is $6.58). Look up Worm shaft and use part number AYP-137051 this part is $6.79.
Not bad for a total of $18.37 and a little weekend work.
HAVE FUN AND GOOD LUCK……….

Hello,

Just wanted to say, having done the same as Rudy. Order part #137050 &137051 The mower drive shaft will spin the opposite direction forcing the drive wheels to rotate backwards. The new worm and helical gear are opposite from the ones removed. New transmission or new mover this time.

Hello,

Just wanted to say, having just placed an order for 133804 and had this rejected, that I found your information quite useful and ordered the two parts.

Thanks.
