bizon 30 #1 Posted March 20, 2019 Hi everyone i got myself a wheelhorse 416-8 with manual gearbox Can anybody say me wich pulleys i can search for speeding up my horse? It does not need to race but a bit more speed ( tinking about 15-20 miles/h if possible!) I was thinking to use the low gearing to mow and drive normal And the high gearing for long distance cause now when i have to drive the engine make much sound and no speed at all dont worry i am going to make a front axle with brakes, it is also going to run on atv tires and rear tires 26*12-12 much wider so it will not turn over 😎 tnx mates! Ohw and.. excuse me for my bad english.. i live in belgium 2 Share this post Link to post Share on other sites

To make your go five times as fast as it was designed to go could be hazardous to say the least. You would probably need to go from the engine to a 5:1 gear box and then on to the drive pulley on the transmission. If you only put a smaller pulley on the transmission and a larger one on engine you probably wouldn't even double the speed. 2 1 Share this post Link to post Share on other sites
WHX?? 47,345 #3 Posted March 21, 2019 Your gearbox was not designed to go much over 6-7 mph ... anything over you are taking your life into you own hands. Over here we would call it hold my beer and watch this. You might be able to get 9 -10 out of her but that's even pushing it. I would suggest you look for a different tractor you want to have that kind of road gear from. Probably not gonna happen with a WH front brakes or not. 1 Share this post Link to post Share on other sites

WHAT, I made one that went over 30 mph with a 8 speed trans. But yeah, it was kinda "hold my beer and watch this" but...still fun 20 mph is too fast to still use it for tractor duties in my opinion but it is possible Use this pulley calculator. Plus fill the trans with motor oil instead of gear oil. http://gadi.agric.za/software/renting/pulley_calc.php 5 Share this post Link to post Share on other sites
cschannuth 3,814 #5 Posted March 21, 2019 I upsized the front pulley on my 606 from a 2 1/2 inch to a 3 1/2 inch and went from 5 mph to over 8. I would think upsizing the front pulley a couple of inches and downsizing the rear pulley a couple of inches would make a huge difference in speed. 1 Share this post Link to post Share on other sites
