Abstract

Rotary mower is used for cutting grass as a part of landscape maintenance. Cutting torque and cutting result are two important factors that have to be considered in designing the rotary-type mower blades. The objective of this research is to develop a mathematical model for calculating the cutting torque of rotary-type mower and validate it by conducting cutting tests. A mathematical model for predicting cutting torque was developed by kinematical analysis of cutting mechanism. The model showed that the cutting torque of rotary-type mower continuously changed and was influenced by cutting radius (R), forward velocity (v), rotational speed of blade (n), blades number (k), rake angle (), grass diameter (dr,), grass spacing (j), and specific cutting force (p). The model gave a good representation of the cutting torque measured experimentally. Key words: rotary mower, free cutting, grass, cutting torque.
