The present invention relates to a light weight horticultural binding machine, and more specifically, a tape holder formed on one side and a tape storage box on which a binding tape is wound in a rolled shape is installed at the bottom of the main body frame, and the top of the main body frame. A binding needle feeder is installed to form a binding portion at the front end of the binding needle feeder, and an elevating actuator equipped with a pressurizing lever is connected to the upper end of the main body frame by a rotating shaft to be rotated, and at the distal end of the elevating actuator In an ordinary horticultural binding machine that installs an actuator and pulls the binding tape through the actuator to the binding unit, binds with a binding needle, and then cuts the outside of the binding unit with a cutting knife, the lifting mechanism is made of aluminum alloy, At least one through hole is formed on one side of the lifting actuator, and the pressure lever is injection molded from a plastic material. According to the present invention as described above, only the steel lifting actuator that is installed on the upper part of the body frame and rotates up and down and repeats operation is changed to an aluminum alloy material, and a plurality of through holes are formed on the surface of the lifting actuator. , Reduces product cost while reducing material cost to a certain extent, so that fatigue does not occur even in frequent operation to bind seedlings. Moreover, the plastic lever is formed with a metal material, so that only the handle body part is separately plastic injection molded. When the pressure lever is operated, the rotating shaft coupling part is made of metal, so that support for external force can be achieved to some extent, and the product is made lighter by the material of the handle body. There is an effect to improve the workability by applying a small amount to the. In addition, it is possible to improve the durability of the product
