Want to make my lawn tractor faster

What is the easiest way to make a lawn tractor faster?

get a 3" pully for the transaxle and a 4 1/2 to a 5 1/2 for the engine but when you do this remeber your gonna be going fast to i recommend a tether switch just incase you fall off it will shut off and not run you over

Even if I have a very small engine

how small

Yes, even with a smaller engine you can go fast. Just takes you a little longer to get there. The big engines really are there to run accessories... it takes nearly nothing to make a mower move...

K thx and 10 horse

I guess it's not that small

Since my deck drive pulley is 5 1/2 is there a way to use that as a engine pulley without lifting the motor

Yes, all you have to do is cut it off(Not with the shaft) And cut the top one off. Then all you have is a shaft with the key in it. Then take the bigger pulley and weld it where the original top pulley went(centered). Then put it on your tractor and get a bigger belt. Then drive around on your tractor until you break something else.

Sounds like a plan

Those pulleys will put you at 35 mph.  I would go for a one to one ratio, or in other words, a 5 on the front, and a 5 on the transmission.  This will be 15-20 mph, which is all the faster you should go on stock steering/brakes.

I had a 8hp and a 10hp, they went plenty fast.

if its for off roading, definatly do a 6 to 6 or 5 to 5, that way you still have some tourque left over to spin the tires but you can still go like 15.

Ok thanks

is this going to bean off road tractor or does it have another purpose?

Off road

Or a racing mower but probably off road
