I recently acquired a 5' Rhino Finish Mower. First time I used it was a little rough cutting. I ordered the stock blades for the unit. Replaced the blades and the cut was terrible. I thought maybe I put them on upside down. They were on right side up but upon checking the rotation they were turning backward. In this case backward was counter clockwise. According to everything I have found the stock blades should indeed turn counter clockwise. The PTO on the Ford 3930 turns clockwise as do the blades on the mower. I have had no luck finding blades with clockwise rotation. Any ideas on what is wrong here or where to obtain clockwise blades. Thanks.
