How would I go about making a craftsman lawn tractor with a 5 speed faster?Mayb to about 25 mph. I was told that taking off the governor would do it but wouldnt the engine run too fast and wear something down?

The best way is to change your pulleys. You can just put a smaller one on the back.
The best thing to do is make the front and back pulleys the same size.

Don't do anything to the engine till you have rode around for awhile.
Take it easy and slow there is nothin safe about doing this you will get hurt

Can it be done without changing the pulleys because I wanna stay away from that

You can get more RPMs out of the engine and maybe get 3 more mph out of it.
Or change the back pulley and go twice as fast at half rpm

my friend done this for a festival.they took a J.C, penny rider and had the police clock it at 40mph,the brakes were bails of straw at the end of the strip

What are brakes? LOL
I just take my foot off the gas Petal if I have to stop fast I pray and down shift.
It does slow down fast just take foot off gas.
I used a bike hand brake and cable for a gas petal

Why would you need to get so much more speed from the mower, unless you are useing it for racing or the like? I have a DYT 4000 w/24hp B&S gear drive, and have plenty enough speed. Maybe I am getting too old for the higher speed (57 yrs old), sounds dangerous to me.

I have one of my customers that races go carts. They use lawn mower engines and race just about every week end. The only thing they do is remove the governor other then that its a stock. They get around two year running out of a engine. I don't know how long a race last or how many races they run in a weekend but he tells me they run them wide open and run somewhere in the 60 MPH range. Just curious why do you want your lawn mower to go so fast? I agree with the other post you would be a lot better off by changing the pulleys along with the governor. Also does anyone know what kind of RPMs you get out of a mower engine without a governor? As far as a working lawn tractor gos I try to keep them in the 3500 + or - RPM range.

well I'm not really sure but when i was racing 5 horse brigs engines i think i was getting 6000-6500 out of it but it wasn't a constant it was wide open then off the gas wide open then off the gas and never run it wide open unless under a load they will explode lol

How long would you like the motor to last before changing it out? From my experience, messing with or unhooking the govenor and revving the motor at a lot higher rpm's is pretty hard on it and will send it to the grave about as fast as the things revs. I personally dont have the extra money and time to be changing out motors. At least (hopefully) the motor is somewhat enclosed for if and when the motor comes apart, better you than me. I guess I am just too much into fast or racing them other than maybe watching someone else from a little distance. I would do like some of the others say, change the pulleys, easier and cheaper. Thanks, just my opinion.

:smile: Wether this LT has a tranny/transaxle. If you change pulleys for more speed or jerk the gov. more r's. You had better pull the reverse chain from which ever you have, or your going to blow the back out of the case when the chain explodes. Also up grade the brakes and steering or you are will be and accident waiting to happen.
