Overview#

The Triton Power TP-JD350-T3-UL is a 350 kW (438 kVA) diesel standby generator powered by the John Deere 6135HFG09 turbocharged six-cylinder engine with 13.5 L displacement. As a Tier 3 unit, it avoids the aftertreatment complexity of Tier 4 Final models while still meeting EPA requirements for stationary emergency standby applications. The UL2200 listing confirms compliance with safety standards required by most building codes for commercial generator installations.

Paired with a Leroy Somer alternator, the TP-JD350-T3-UL delivers reliable three-phase power at 1800 RPM in 120/208V and 277/480V configurations. The 6135 platform's 13.5 L displacement provides ample power reserve for motor starting and block loading typical of large commercial facilities.

Our service experience#

The John Deere 6135 is the workhorse of the 300-400 kW generator class, and its Tier 3 configuration eliminates the DPF and SCR maintenance that adds cost and complexity to Tier 4 Final units. For qualifying stationary emergency standby installations, this translates to meaningfully lower total cost of ownership. The UL2200 listing streamlines AHJ (Authority Having Jurisdiction) approval for commercial projects, which is a significant advantage during the permitting process.

Fuel consumption ≈ 17.36 GPH at 75% load. Estimate based on industry-typical 1800 RPM standby curves (≈0.07 GPH/kW at full load). Actual consumption varies by engine, ambient temperature, fuel quality, and tuning.

Frequently Asked Questions

What does UL2200 certification mean for this generator?
UL2200 is a safety standard for stationary engine generator assemblies. It certifies that the TP-JD350-T3-UL meets rigorous construction, safety, and performance requirements, which is often required for building code compliance in commercial standby installations.
Why is this unit Tier 3 instead of Tier 4 Final?
The TP-JD350-T3-UL is designed for stationary emergency standby applications where EPA Tier 3 emissions compliance is permitted. Tier 3 units avoid the complexity and maintenance overhead of Tier 4 Final aftertreatment systems (DOC/DPF/SCR), resulting in lower operating costs for qualifying installations.
What engine powers the TP-JD350-T3-UL?
The unit uses a John Deere 6135HFG09 turbocharged six-cylinder engine with 13.5 L displacement, running at 1800 RPM. The 6135 platform is John Deere's largest inline-six industrial engine.

Why we recommend Triton Power

Triton Power is our value brand for mobile and portable diesel generators, and an emerging option for industrial standby. When MQ Power's pricing is a stretch or lead times are too long, Triton delivers comparable capability at a lower price point with faster availability.

We are developing our Triton Power sales relationship and building fleet experience. Every engine platform Triton uses — Perkins, John Deere, Kubota, Scania, Volvo — is one we already service daily across other brands. Triton's open architecture means our technicians can maintain these units with standard tooling and widely available parts.
