John Deere JD14 Engine: Proven and Ready for Action

JD14 Engine

Field-Proven – Proven and Ready
300- 510 kW (402- 684 hp)

John Deere JD14 engines have been working more than 11 million hours at high load in a variety of applications.

They’ve demonstrated more than 6 million hours of torque and lugging power in tractor operations. So, when you install a John Deere JD14 engine in your application, you can be confident in the performance it delivers.

Many of these operating challenges were even more extreme than typically confronted in the field:

Repeating high to low loads to confirm thermal durability

Block loading to show strength

Ultra-low idling to demonstrate oil pressure capabilities.

Solid Performance

13.5L

The JD14 engine provides more power per liter than 13.5L configurations.

11%-14%

With 11% increased peak torque and 14% higher power, it allows your machines to work faster, lift more, and operate more efficiently than ever before.

45%

This engine has been shown to increase harvesting capacity by up to 45% on John Deere X Series Combines.

The JD14 features a rear gear train that reduces noise by up to 3 decibels compared to the 13.5L engine. That’s half as loud, greatly improving operator comfort.

Easy to maintain Low service costs

John Deere engineers streamlined common maintenance steps on the JD14 engine.

Hydraulic lash adjusters decrease valve wear longer engine life while eliminating valve lash maintenance.
An advanced control system analyzes sensor data to keep operators working without interruption.
Prognostic capabilities are built into the engine to help users identify potential problems and schedule service prior to downtime.
Proven John Deere cooling packages are available with JD14 engines for easy, low-cost integration.
The JD14 is compatible with renewable diesel fuel and biodiesel blends.

Operational Flexibility

The compact JD14 engine is shorter and narrower to fit in more machines with minimal reconfiguration.

It provides up to 130 kW (174 hp) through forward auxiliary connections and via an integrated rear SAE-C PTO.

It has common connection points across different emissions configurations for the U.S. and Europe and is available in single- and dual-turbo configurations to maximize packaging flexibility.

Durable in-line aftertreatment provides unified packaging and is available with a DPF for Stage V applications and with no DPF for Final Tier 4 applications.
