Abstract: The percent of sugarcane mechanical sugarcane loading (in Egypt) has not been exceeded 10% because of the poor\nfinance-ability of the farmers to by the imported self-propelled loaders. The local workshops have been attempting to\nfabricate a sugarcane loader attached to the farm tractors as a cheap alternative. Farmers did not accept the tractor-mounted\nloaders fabricated locally because of the problems concerning poor efficiency and poor balance of the tractor-mounted loader\nwhile operation. The main objective was to overcome the problems concerning precise fabrication of the\ntractor-front-mounted loader and to develop an efficient dynamically balanced machine. Fabricating a sugarcane grab loader\nfor the tractor faces difficulties due to the variation of the farm tractor types and sizes. Reference to the size of the transport\nvehicles was supposed to be loaded, the medium size tractors 70-90 hp was considered to be equipped with the sugarcane loader.\nThe most important specifications of the prevailing medium size farm tractors found in the sugarcane production area were\nrecorded through field survey. Important tractor parameters related to the loader design were specified. For the prevailing\nmedium size tractors of power range 70-90 hp, wheel base within 2.4 m. Total tractor weight about three tons, distributes as\ntwo thirds on the rear axle and one third on the front axle. The tractor operator is supposed to have clear view over the boom\nlowered for pilling, so that the height of steering wheel is important parameter determined as 1.9 m for the medium size tractors.\nImportant dimensions such as the tractor chassis dimensions and other dimensions related to the sugarcane loader were\nidentified. A chain of measurements and computations were conducted to facilitate optimizing the design of a tractor mounted\nsugarcane grab loader dynamically balanced with no need for counterbalance weights. Considering the data of the medium\nsize tractor, the dimension of the loader components computed in accordance. A general formula relates the loader size to the\ntractor on which the loader supposed to be mounted was developed to facilitate fabricating the balanced loader for any size of\nthe farm tractors. The loader was fabricated and tested in the field. The loader proved high dynamical stability and\neconomical operation efficiency. The field test results show operating the loader for loading sugarcane transport vehicles,\nloading cycle time was about 1.7 min, loading rate up to 14 ton/h and operation efficiency was over 90%.
