Rotary Cutter speeds
Normal agricultural input shaft speeds are 540 or 1000 rev’s per minute depending on the tractor being used. Because of this variation of input speed care must be taken when selecting a gear box for your application. If the blades rotate too slowly they may not cut properly. If the blades rotate too fast you may also experience cutting problems however excessive speed is more likely to cause damage to the machine or serious injury to the operator.
The chart below shows the tip speed in feet per minute for some commonly used cutter blade diameters. This is a guide only to assist you with the selection of your gearbox. You will see that some models are marked as not recommended for the reasons covered above.
