what is faster a bigger belt and pulley or a smaller belt and pulley for a riding lawnmower?

Question

which one would make the lawnmower go faster?

Answer 1

Smaller would be faster.

Answer 2

Higher top end speed would be a smaller drive pulley, or smaller driven pulley. They also make a variable pulley, that is big at low rpms, then changes, the faster you go, the smaller it gets. This way you have fast acceleration, and a high top end speed as well. In fact, you can put one like that at each end, both drive and driven. This system is exactly what the old Honda Odyssy 4-wheelers used to use, a centrifugally controlled constantly variable pitch sheave at both drive and driven pulleys. One got smaller and the other got bigger, the faster you went the faster you could go!

Answer 3

well, it might depend on how MUCH power your lawn mower engine puts out, if it's undersized for the mower, putting a bigger pulley on to get more power may backfire, as you lose torque when you gain upper end speed. Acceleration may lag quite a bit. You have to balance the power with speed. But the Answerers before me are correct, in the general sense.

Answer 4

If driver pulley, then bigger would make it faster. If its the driven one, the smaller pulley would make it faster.

Answer 5

Larger pulley on engine, or smaller pulley on transmission.

Answer 6

if you want the engine to have lots of power use the smaller ones. if you want the engine to go fast but may take a little to come to speed use big ones. the one on the engine should be bigger for more speed but not as much rpm's.
