You can interchange rear mount attachments like a tiller or a plow between the BCS and Grillo. You cannot interchange front mount attachments like a mower or snowblower. The reverser determines the rotation of the PTO, so you can mount stationary attachments and set the reverser to reverse. Be careful, though. If you forget to set the reverser to reverse, you'll run the attachment backward. I imagine a generator or pressure washer would not like that...
