Of course all of this would be to overcome and compensate for the fact that I only have a single speed PTO. Trying to get the benefit of a higher speed without having to buy a new tractor. |
If you can find a TaperLock pulley to fit your top shaft and also the housing (you can modify the pulley cover)you can speed up the rotor and lower the engine revs accordingly . Do'nt go smaller on the bottom pully as you will find it is allready at the belts diametre limit . If you exceed this limit the belts will fail ie. if they are cog type belts you will see the cogs are nearly touching each other as they wrap around the bottom pulley .
