Little help on how to make lawn mowers go faster?
Ok, I know if you get a bigger pully in front it will speed up your lawn mower. I was wondering if I could leave my back pully in or do I have to replace that one too? Also, does the front pully have to bigger than the back? What size should I get? It's a four-gear but the fourth gear doesn't work, so it's pretty much a three-gear. I'd like to go about 20 MPH in 3rd gear. Also, this is NOT for mowing. We gave it to my nephew for his birthday and we took off the blade. Also, I don't think I'll be pulling anything with it. But I would like speed, about 20 MPH, and enough power to go up steep hills good. I just want to know if I can just put a bigger one in the front and leave the back one in. And also if the front one has to be bigger than the back one. I doubt the front one has to be bigger, but I just want to make sure. I can get a longer belt, so I don't mind increasing the first front one's size and keeping the back's size the same. In fact, I would much rather have the back one stay in so I can just replace the front pully with a bigger pully.
P.S. if someone has a calculator where I can see what size will go so fast, could you please put the link up?
