13.6L (827-cu in.) engine
The muscle to handle heavy draft disks and rippers, power-hungry air seeders and planters, and large transport loads like grain carts and slurry wagons. The durable design and heavy-duty components you can depend on when you need to get in and get out. All in a Final Tier 4 (FT4) and Stage V compliant package. You get real-world power with the purpose-built 13.6L (827-cu in.) engines from John Deere Power Systems, standard in the 291 to 440 engine kW (390 to 590 engine hp) 9 Series Tractors.
We developed our newest power plant from a clean sheet of paper, starting with stronger castings, beefier bearings, and more robust internal components, all designed to meet the high demands of field operations. We replaced the fuel injectors with a high-pressure common rail (HPCR) fuel system and eliminated the diesel particulate filter (DPF) to boost to fuel efficiency and lower operation and maintenance costs. Integrated coolant and oil passages, along with a new belt-driven water pump, eliminate potential leak points and allow for a less-crowded engine compartment, improving serviceability and reducing debris accumulation.
In redesigning the engine, we also gave it:
- Hydraulic valve lash adjusters to maintain valve-lash settings during engine operation, reduce valve train noise and wear, and allow for greater fuel efficiency.
- A hydraulic fan drive for improved cooling capacity with no required maintenance.
- A new integrated wiring harness design featuring a modular layout for reduced vibration, greater reliability, and easier service and diagnostics.
- A rear gear train that integrates fully into the cast-iron block, reducing tiresome engine noise and improving the durability of the crankshaft damper.
- Combination sensors where possible, meaning fewer sensors, connectors, and wires.
- A powerful engine brake that allows operators to use the engine to control tractor and implement speeds while transporting or traveling downhill, reducing wear on the drivetrain brake components.
It all adds up to:
- 14 percent more power and 11 percent more torque
- 3 percent lower fuel consumption
- 10 percent lighter
- 27 percent reduction in mean repair time and an estimated $8,308 savings in service costs over the life of the engine
