Many literature sources state that radial ply tires achieve lower rolling resistance values than cross ply tires. From a certain point of view, radial ply tires are gentler on the ground than cross ply tires. The effort was therefore to experimentall

Chipless tree cutting is increasingly becoming more popular because of its low weight and greater throughput due to the small dimensions of the entire cutting head. This paper is focused on the design of the crank plate of the cutting mechanism of a
