A: On a single-spindle brush hog like the CountyLine 6 ft. Round Back Rotary Cutter, this terrifying shaking and clanging is a very common occurrence that is usually caused by operational habits or a simple, fixable alignment issue rather than a product defect 1. Normal PTO Engagement Shudder Rotary cutter blades are designed to swing freely on their mounting bolts. When the machine is turned off, the blades hang loose and often fold inward toward each other The Cause: When you first engage the tractor's PTO, it takes a few seconds for centrifugal force to throw the heavy blades straight out. During those first few seconds, the blades can clank into each other or the stump jumper, causing the PTO shaft to bounce violently The Fix: Always engage your PTO at low tractor idle (lowest RPM), then slowly ramp up to the operating speed (usually 540 RPM). If you dump the PTO at full throttle, the sudden shock will make the blades slam together violently and can snap your shear pin. Give it 5 to 10 seconds to smooth out 2. Jammed or Locked Blades If the bouncing and knocking do not stop after a few seconds, the blades may have physically locked up on top of one another. • The Cause: If you hit a thick stump or rock—or if the mower was dropped heavily—one blade can swing backward so hard that it overlaps and catches on the other blade. When both blades are stuck on one side of the stump jumper, the unit becomes completely unbalanced, making the mower shake like it is going to fall apart. • The Fix: Turn off the tractor, pull the key, and disconnect the PTO shaft for safety. Safely look under the deck. If the blades are jammed together, use a heavy mallet or sledgehammer to hit them until they break free and point in opposite directions. 3. Loose Stump Jumper / Main Output Nut • The Cause: If the large castle nut holding the round stump jumper pan to the gearbox gearbox shaft is loose, the entire pan will wobble. This wobble changes the blade trajectory, causing them to clip the deck or each other while forcing the input shaft to jump around. • The Fix: Check the underside center nut. It needs to be tightened securely (often requiring a large impact wrench) and locked in place with a cotter pin If you ensure that you are engaging at low idle, verify that the blades are free-swinging and pointing in opposite directions, and confirm the stump jumper is tight—but the shaft still bounces uncontrollably—you may have a factory defect.

A: Yes, this rotary cutter does not come with front or rear guards. While front and rear rubber guards are available for all units, they are not included and must be purchased separately.

A: The cotter pin and 38mm castle nut on the bottom of the blade holder will need to be removed and then you may have to take a piece of wood and tap around the outer edge of the blade holder. There are instructions in the owner's manual on removing this.
