The main objective of this study is to evaluation and develop the cutter blade of the portable machine for turf grass shear to
increase its shearing efficiency, used in garden and club selfsame small areas and estimate the operation cost. The performance
of portable machine for turf grass shear in terms of field efficiency, cutting efficiency, energy requirements and shearing cost
were investigated dependent on change in kinematics parameter (ratio of knife peripheral velocity to machine forward speed), knife
types (fixed imported cutting blades and free modified free cutting blades ) with three and four cutter blade during the shearing
operation .The operating shear a kinematic parameter of 290 which corresponded to forward speed of 0.25 m/s, knife velocity of
72 m/s was the optimum. The best adjusting of the knife of the machine at cutting height of 4 cm with moisture content 40 % was
used free modified knife with three cutter blade.
