I have this pto converter made by ARK Mfg. that changes the shaft rpms from 2000 rpms to 540 rpms. Was told it was mounted on Super Cubs or the 82 series. I have no manuals or other info about it. Does anybody know anything about it.
Howard, ARK made loaders for Allis Chalmers/Simplicity garden tractors. The 2000 rpm to 540 rpm adapters were likely made for the Allis Chalmers 616, 620, 720 and Simplicity PowrMax 4041 and 9020 garden tractors. Here's some info, click HERE I have an Allis Chalmers 620 with the 2000rpm rear PTO and an Ark model 600 loader.
