Well, my honda 21'' mower has 130 hours on it, (lost the hour meter today btw) and the transmission is crapping out on me. There's oil slowly comming out of the gear box, those rods going to the wheels are bent, which are causing my wheels to bend.. I need a new transmission. They cost about 50 bucks, but from the looks of it, it looks like it's going to be a pain in the a$$ trying to replace it. Has anyone every replaced one themselves? How long did it take? ANything i should, or shouldn't do?
