I quit. Another 200 bucks and a mower down for 3 days until my THIRD NEW ELECTRIC CLUTCH comes in. This has got to be from doubles. I admit that they cut well but I cant spend 200 bucks for a clutch after 70 hours of use. I replaced it last August and now its shot again. The first one went after I had doubles. I wouldn't believe it. I didn't want to believe it. The unit is a Toro Proline 15HP walkbehind Hydro 44" cut. It cuts real well when the clutch is working. I have the Walker 52" SD deck with factory doubles and that works nice but no more for the Toro. I just lost all the money that I made with the doubles supposedly helping me go faster. Oh well, it was nice while it lasted. I'm just gonna stay with the atomics and thats that. Good Luck.
