✦ Synopsis
Experiments were conducted in a laboratory soil bin with clayey soil to determine the tractive performance of cage wheels as a!ected by opposing circumferential lugs, lug spacing and wheel slip. Also, the performance was compared with conventional or normal cage wheels. The power of the modi"ed wheels reached a peak at about 30}40% wheel slip depending on the circumferential angle and lug spacing. The modi"ed wheels with 153 circumferential angle at 24 and 303 lug spacings showed signi"cantly higher tractive power compared to other combinations. Although the power of the modi"ed wheels was higher than that of the conventional wheels, the traction e$ciencies between the modi"ed and normal wheels were not signi"cantly di!erent. The average wheel slip at the peak tractive e$ciency was about 34% for all circumferential angles and lug spacings. Based on the performance and cost of materials, the cage wheel with opposing circumferential angled lugs at 153 circumferential angle and 303 lug spacing is recommended for the design of power tillers in Thailand.
