Possibly through a 'gas' pedal? Exactly why I was asking. Paired with the right controller, you could have a "hybrid" foot controller that works similar to a hydro but with different gear box speeds. Or just stop and go like those electric cars we had when we were little. Either way will be pretty cool! 2 Share this post Link to post Share on other sites
Racinbob 12,501 #28 Posted January 2 Just my worth. I see no reason for a 'clutch' as such. You don't need to disconnect the motor drive to come to a stop. I'm thinking a soft start might not be best. You want full torque to get her rolling. A variable speed control....yup. Think electric golf cart. 5 Share this post Link to post Share on other sites

I'm curious- what will you use to replace the clutching function? No clutch. Going to be like an electric golf cart, motor only runs when you depress the throttle and I’m going to have a forward/reverse switch so no need to shift gears often 1 Share this post Link to post Share on other sites

So pop quiz: With the electric switch in reverse and transmission in low reverse, how fast will Johnny go? For extra credit, in what direction? Answer: He won’t go at all until he presses the pedal.

Will heat or cold affect your design? Temperature is a factor. This battery has a heat function for cold weather operation but I need to be mindful during the hot summer months. I’m using this tractor for my garden so not much use during middle of summer when crops are growing. Share this post Link to post Share on other sites

Curiosity got the best of me and apparently they are used for high end performance golf carts and other apps probably including EVs. When I was told $$$$$.$$ for replacement batteries for her Prius I know why now. 2 1 Share this post Link to post Share on other sites

Thank you for the battery cable link. The controller charges when off the throttle coasting which won’t be much on a tractor. The battery came with a charger you can mount onboard or offboard. 2 1 Share this post Link to post Share on other sites
