Motorized Pedal Tractors
A few years ago FARM SHOW published a story on how I motorized a 1965 Deere Pedal Trac pedal tractor (Vol. 35, No. 3). Since then I’ve motorized several other brands of pedal tractors, including a pair of Deere 5020’s, an Oliver, and a Western Flyer. All are powered by a 1981 Echo 21 cc weed trimmer engine that’s hooked up to the transmission of a Troybilt rototiller. The transmission chain-drives the tractor’s rear axle, except on the Western Flyer which uses the gearbox off a cultivator attachment.
An add-on, spring-loaded throttle lever is used to control tractor speed. The weed trimmer engine has a built-in clutch and the rototiller transmission has a worm gear drive with a 36:1 ratio, so when I let off the throttle the tractor stops. There’s no need for brakes.
The 2-cycle weed trimmer engine doesn’t have much torque unless it’s revved up, and would have run too fast for the pedal tractors so I had to gear it down. To do that I cut a tine shaft off the rototiller transmission shaft and cut another shaft down to make it shorter.
I bought the Oliver pedal tractor new in the box from a friend and motorized it right away. The tractor came with a side cover over the entire engine, just like on the real Oliver, which made it easy to cut out an opening for the weed trimmer engine. (Tom Demers, 267 Hard Hill Rd.
