Got my Yardman frt. dr. 21 in. 159cc walk behind #12avb22j701 today UPSground. Satisfied except fwd jammed so I took off the front wheels for inpection and what did I find. A small piece of plastic had broken off the drive wheel and was jammin up the gear. I picked out the piece of plastic and problem solved. Glad I'm a half-**** mechanic and found this....The End..
