Title: gearing
Post by: finn1 on July 17, 2014, 11:54:16 pm
lets say theres a 14 tooth sprocket on tranny and a 42 tooth sprocket on rear axle. now changing just the tranny sprocket to a 12 tooth would that raise or lower my rpms? another words more top end speed or more torque coming out of the corners?thanks for any help bob

In short the 12 will be slower at the same RPM but more torque Best bet would be to go to EC website.  Click on "Technical Info" toward the top in blue writing on the home page. Then click on EC Distributing Mower Speed Calculator.  You will need your tire circumference.  For me this is easier and let's me see different combos and you can adjust your RPMs up or down.  Just remember more speed less torque more torque less speed.  Hope this helps.
