hiya all. i have a client whom was having me cleanup his old storage shed. I pulled an old mower out, he looks at it says, "well, i don't need that, put some gas in it and see if it works, if it does take it if you want". the mower is an old 22" 4HP self propelled mower. i think he said he got it a JC Penny. what the problem is, is that the self-propelled mechanism only goes backwards, is this fixable? i was needing to buy a new 22" mower anyway, but if i can use this one for the rest of the season it helps me greatly. any advice would be appreciated. by the way, he also offered me an un-used tow behind yard cart.
