meadowfield 2,545 #1 Posted September 24, 2016 (edited) I've thought of this for a while, it's not a new idea... But will give me shift on the go, and either speed up or slow down if I'm ploughing and need a little more power. Its a variable speed pulley on the engine, giving me around 20% more speed or torque depending how you look at it. Just the actuator lever to sort, before I need to print some 12 speed decals Edited September 24, 2016 by meadowfield 13 Share this post Link to post Share on other sites
Aldon 4,826 #2 Posted September 24, 2016 Have thought of doing this as well. I will follow this and hope you have a glowing report when finished. 1 Share this post Link to post Share on other sites

tunahead72 2,346 #5 Posted September 24, 2016 I'm always amazed here, some of you guys have some crazy good ideas and skills! I can't wait to see a video of this one in action. I have no idea what I'm looking at in your photos, but this sounds like the Torque Amplifier on the old International Harvester farm tractors, any similarities? 1 Share this post Link to post Share on other sites

bslms 19 #8 Posted September 25, 2016 We had a Massey Ferguson 10 hp back in the late sixties with the same sort of variable pulley. If I recall, on the MF the pulley was between the engine and trans axle and had 5 district speeds for each gear. You had a speed for any situation. It was a good tractor, just had a frame that was a little weak as the welds would fail. Share this post Link to post Share on other sites
jdleach 525 #9 Posted September 25, 2016 Well Meadowfield, been digging around in your variable-V drive drill press? Took me a minute to see what you were doing. Most vari-V drives employ two variable pulleys with some sort of cable arrangement to shift the widths of both pulleys at the same time. I see that you are using an idler to compensate for the changes in pulley spacing. Simple and elegant design. Share this post Link to post Share on other sites
