Changing the lug height on a snowmobile track can slightly affect the final drive ratio, particularly on different surfaces like snow or pavement. On hardpack, the effect is similar to driving on pavement due to the larger radius at the lug tips, while on soft snow, the effective center of drive force may vary, leading to minimal changes in drive ratio. The overall impact of lug height on performance is likely negligible in practical scenarios, as the radius of the drive pulley and track thickness play a more significant role. The discussion emphasizes that the drive ratio is primarily determined by the drive wheel's radius and the number of teeth on the drive system, rather than the track's thickness or length. Ultimately, empirical testing is suggested to determine the optimal setup for specific conditions.
