The redline torque of the Kubota engine is where the engine pulls weakest, producing only a total of 37 foot-pounds when the throttle is opened to the full 3,600 rpm maximum.
Peak torque of the Kubota engine arrives earlier at 2,400 rpm on the tachometer, producing a total of 41 foot-pounds, along with 19.5 horsepower at the time.
The relatively low dropoff between the low-end redline torque and the peak torque figures--only a difference of four foot-pounds--indicates a fairly linear torque curve, meaning that the Kubota engine will be able to pull and accelerate cleanly from almost any part of the rev range, even under towing load.
