American-engineered diesel engines, built for heavy-duty continuous operation. John Deere's long-stroke engine design develops peak torque at low RPM — meaning less wear, better fuel economy, and significantly longer engine life. With wet-type cylinder liners and heavy-duty components, John Deere engines are rated to exceed 50,000 operating hours. Where Kubota excels in small power applications, John Deere is the choice when you need serious power, long runtime, and low cost-of-ownership over years of operation.
