The friction properties of grain products are one of the important parameters that are considered in the design of transport, transmission and storage structures and equipment. In addition, the friction force and coefficients on different surfaces are important in the selection of the power supply required for such design of structures and in the calculation of their actual dimensions. These are the common materials used for handling and processing of grains and construction of storage and drying bins. In this study, the static friction force and static friction energy were measured on 4 different material surfaces (rubber, chrome, galvanized sheet and PVC) and 3 different moisture contents (9.30%, 18.50% and 29.00%) for Karacadag Beyaz and Karacadag Karakilcik local rice varieties. The pulling of the grain box on the surface and the friction forces and energy were measured at a constant speed of 20 mms -1 with Llyod tester having a capacity of 2500 N.  There was no significant difference between the varieties in terms of frictional force and friction energy (p> 0.05). However, the effect of surface material and grain moisture content was found to be very important (p <0.01). As the moisture content of the grain increased, the static friction force and friction energy values increased. The highest values were obtained in PVC and rubber material with a moisture content of 29.00%, the lowest value was obtained in chromium material and 9.30% moisture content.
