PowerTech Transmission Auxiliary Equipment
John Deere Powertech radiator-cooled and dry-exhaust manifold engines (models TF and HF) meet EPA Tier 3 requirements and are designed for marine auxiliary equipment such as pumps, winches, deck cranes, and hydraulic systems. We also offer a variety of optional accessories. John Deere Powertech radiator-cooled, wet exhaust manifold marine engines (Model HFM) are specifically engineered to provide auxiliary power for ocean-going vessels and carry type approvals from various classification societies.

Description:
To better accommodate the operating conditions and workload intensity of all vessels, John Deere has classified all its models into M1-M5 ratings, enabling users to more effectively select and match equipment for their vessels.
M1~M5 Power Rating Specifications：
- M1: Refers to continuous operation without shutdown restrictions, where the load exceeds 65% during operation.
- M2: Annual operating hours 3000–5000 hours, with 16 hours of operation within any 24-hour period, under load ≤65%
- M3: Annual operating hours 2000–4000 hours, with 4 hours of operation within any 12-hour period, under load ≤50%
- M4: Refers to annual operating hours of 1000–3000 hours, with 1 hour of operation per 12-hour period, where load is ≤40%
- M5: Refers to annual operating hours of 300–1000 hours, with 0.5 hours of operation per 8-hour period, where load is ≤35%
- Example: An engine consumes 160 liters of fuel during an 8-hour operating period, with full-power fuel consumption at 60 liters per hour. The load factor is 160 liters (60 liters/hour × 8 hours) = 33.3%.
- Complies with ISO 8665 and SAE J1228.
- Do not start the engine during the remaining 16 hours.
