- General Information on Flail Mower Vibration
- 1. Wire, rope, string, rags, etc., around the cutter shaft are holding the knives in a folded back position. Remove such foreign objects and be sure all knives are free to swing to the extended position.
- 2. Knives are missing or broken. Replace missing or broken knives.
- 3. Knife hanger lugs are broken off shaft. This condition usually results from continued operation in contact with large hard objects where the knife hanger lugs themselves are hitting the hard objects. Lugs should be replaced using arc welding equip...
- 4. Cutter shaft ball bearings are worn enough to have radial “play” in them. Replace ball bearing and other worn parts to eliminate “play”.
- 5. Shaft is bent. The shafts are straight within a couple of thousandths of an inch when they are made. It is possible that they will become bent in use, such as if the shaft is hooked on a stump while the tractor is moving forward at good speed.
- 6. Shafts are operated at improper speed. Rotating shafts have what is known as a natural period of vibration. The same is true of the cutter shafts on the Flail Mowers.
