Development of a Variable-Diameter Cage Wheel for Walking Tractor and Its Performance Evaluation in Soil Bin (Simulating Wetland)

Cage wheel is commonly used with walking tractors, but its diameter suitable for getting maximum tractive performance needs to be studied. Hence, an open-lug-type variable-diameter cage wheel to fit with a walking tractor was designed using SOLIDWORKS 2016 software. After verifying its dimensions by using finite element analysis, an actual wheel was fabricated with provision to vary its diameter from 620 to 710 mm using a manually operated...
