I was just wondering why exmark does not offer an OCDC. I know Dixie Chopper does. I also know there are a few aftermarket OCDC's out there that they say are made to fit on an exmark deck. Does anyone out there have any recommendations? Would using one void my warranty? Does anyone have any experiences with one of these that would suggest that I not consider one? thank you in advance for any helpful comments. I just bought my Exmark today. It is 5 below zero here in western NY...it will be months until I can even use it for the first time. It sure looks good in the garage though!
