hey, i have an old continental mower, identical to the mustang mower. if that helps. i cant find any information on this mower at all. i am not worried about history, i just want to get more speed out of it. the gear box only has forward, neutral and reverse. it has an 8hp Briggs and Stratton motor. i dont need it to do 40 mph. but maybe 20 to 25 mph. i read something about changing the pulley's but i dont know exactly what they were talking about. the shaft is vertical, if that helps any. please respond if you could give me any advice. thanks for the help.

Changing the pulley on the motor shaft to a larger one will give you more speed . But it is harder on the engine/tranny and reduces pulling power and take off .

thanks for the info. would it put too much stress on it even though i am not cutting grass, and what about changing the pulley size on the tranny.

Putting a smaller one on the tranny will do the same as a larger one on the motor. I did exactly that a couple years ago on a home built 4 wheeler, that uses a lawn tractor rear end, .

Think about it this way . Jump on a 10 speed bike and put the shifter in first . Easy to pedal , right? Now put it in tenth . Real hard to pedal , right ?

Works the same way when you swap out pulleys as mentioned . You DO put more strain on certain components by changing the pulleys for higher speeds . Mowing or not mowing doesn't make a difference on the tranny/rear end , but does somewhat on the engine ( hence the stutter/bog when engaging blades) . Pulley swaps can effect the whole drive train , including engine .

And BELTS especially!..everything I built from scratch that was too high geared,the belts always suffered the most!...Up in Smoke,like Cheech and Chong!.. I put "stepped" type pulleys,like a drill press has,
on one sit dowm mower I had,so I could just put the belt in whatever "range" I desired ,big one on the motor to small on the tranny for higher speed ,and small to big to get more power..beat being "stuck" with one gear!..
