I have an old 3 point hitch pto driven fertilizer spreader that I'd like to modify to attach to my zero turn mower. Any ideas on where to get a 12 volt motor that will work? I'm not sure what the rpm should be.
The rpm would typically be 540. That is not a common rpm for a motor and would probably require a gear reducer.
The more important issue is power consumption. I expect the motor required would draw more electric power than your mower can produce.
