 automobile wheels, and by means of 

 clamps a steel rim six inches wide is placed 

 on the front wheels after the tires have been 

 removed, as illustrated below. 



By removing the body, mud guards, rear wheels and front tires of the pleasure car and 

 substituting tractor wheels and a small pinion gear in their place a farm tractor is created
