Abstract

The purpose of this article is the theoretical justification of parameters of the felling head elements and experimental studies of the work technique of a one-grip front feller buncher on the basis of the tractor of the drawbar category 0.6-1.4 (16-55 kW). The essence of theoretical study is to determine parameters of the mounted felling head for cutting and vertical holding of a tree of a diameter of 10 to 22 cm, taking into account the optimal working zone of the tilt mechanism. Experimental study was carried out on a prototype of a one-grip feller buncher of the front type (based on the T-25 tractor) with the mounted felling head. In the process of carrying out field studies, technological performance parameters of a one-grip feller buncher for low-capacity logging and the pressure in the hydraulic system of the felling head were studied under various operating conditions.
