The experimens to compare the performance of the garden tractor's wheel were done on the well packed clay loam soil and hard road. The results were summarized as follows:
(1) Inflated pressure of the pneumatic tyre was not so effective on the hard ground.
(2) By adding weight the drawbar pull was increased but the maximum tractive efficiency was decreased on the pneumatic tyre. However on the steel wheel by adding weight the drawbar pull and also the tractive efficiency were increased.
(3) The effect of wheel diameter was much marked on the small dinmeter pneumatic tyre as a garden tractor's wheel.
(4) The drawbar pull of dual tyre was larger than that of single tyre and the tractive efficiencys of them were almost equal.
(5) Wide rim steel wheel could not increase the efficiency and drawbar pull on the hard farm.
