Overview#

The Blue Star JD60-04FT4 is a 60-kilowatt EPA Tier 4 Final diesel standby/prime generator built around the John Deere 4045HFG04 — a 4.5-liter inline-four with SCR/DOC exhaust aftertreatment. This is a current-production active model.

The JD60-04FT4 shares its engine with the JD80-03FT4 (80 kW) but is paired with a smaller alternator for applications where 60 kW meets the load study. Both standby and prime ratings are equal at 60 kWe.

The John Deere 4045HFG04 platform#

The 4045HFG04 is John Deere's mid-range PowerTech genset engine:

  • 4.5L inline-four — stepping up from the 2.9L three-cylinder in the JD40-05FT4, with bore of 4.20 in and stroke of 5.00 in
  • Turbocharged with charge-air cooling — CAC for improved power density and transient response
  • SCR/DOC aftertreatment — selective catalytic reduction with diesel oxidation catalyst, requiring DEF fluid (approximately 4.3% of fuel consumption)
  • 3.8-gallon integrated DEF tank — provides roughly 18 hours of full-load operation between refills
  • 8,400 ft altitude ceiling — excellent for virtually any US installation

Variant selection guide#

The JD60-04FT4 shares its engine platform with the JD80-03FT4:

  • JD40-05FT4 (40 kW, John Deere 3029HG530 2.9L I-3, Tier 4 Final) — smaller engine, no DEF required (DOC/DPF only). Choose this for loads under 40 kW or when DEF-free operation is preferred.
  • JD80-03FT4 (80 kW, John Deere 4045HFG04 4.5L I-4, Tier 4 Final) — same engine, larger alternator. Same footprint, 200 lbs heavier. Choose this if the load study shows peak demand between 60-80 kW.
  • VD100-04FT4 (100 kW, Volvo Penta, Tier 4 Final) — next step up, different engine OEM, for loads above 80 kW.

When to spec the JD60-04FT4#

  • 48-60 kW emergency standby or continuous prime loads on diesel fuel
  • Jurisdictions requiring Tier 4 Final emissions (California CARB for non-emergency, mandated T4F installations)
  • Small-to-mid commercial facilities: retail centers, restaurants, small offices, schools
  • Sites at any elevation up to 8,400 ft

Our service experience#

The John Deere 4045 platform is one of the most widely deployed small diesel engines in the power generation industry, with excellent parts availability through John Deere's dealer network. The SCR/DOC aftertreatment adds DEF replenishment to the maintenance schedule — we recommend including DEF level checks in every monthly exercise visit. The 3.8-gallon DEF tank is adequate for emergency standby use but may need more frequent attention in prime power applications. The 77 dBA open-skid sound level is quiet enough for many commercial installations without additional enclosure, though Level 1 or Level 2 enclosures are commonly specified for noise-sensitive sites.#

Estimate runtime for the Blue Star JD60-04FT4

Adjust load percent and tank size to estimate runtime. Pre-filled with this model's spec where available.

Estimate runtime on this tank

Estimated runtime

53.8 hours(2.2 days)

Fuel consumption ≈ 3.72 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 engine is in the JD60-04FT4?
The John Deere 4045HFG04 — a 4.5-liter inline-four turbocharged-aftercooled diesel rated 133 HP (99.2 kWm) at 1800 RPM. This is the same engine used in the JD80-03FT4 (80 kW), conservatively rated at 60 kWe for this genset configuration. EPA Tier 4 Final certified with SCR/DOC exhaust aftertreatment requiring DEF (diesel exhaust fluid).
Does the JD60-04FT4 require DEF?
Yes. The JD60-04FT4 uses SCR (selective catalytic reduction) with DOC (diesel oxidation catalyst) aftertreatment. DEF consumption is approximately 4.3% of fuel consumption, and the integrated DEF tank holds 3.8 gallons. At full load, the 3.8-gallon DEF tank provides roughly 18 hours of operation before needing replenishment.
How does the JD60-04FT4 compare to the JD80-03FT4?
Both use the same John Deere 4045HFG04 engine (4.5L, 133 HP) and share the same physical footprint (90 x 54 x 66 in). The JD60 is paired with a smaller Stamford UCI224F alternator (60 kWe) while the JD80 uses a larger UCI274C alternator (80 kWe). The JD60 consumes less fuel at full load (4.82 vs 5.96 gph) and is 200 lbs lighter (3,650 vs 3,850 lbs). Choose the JD60 if the load study shows peak demand under 60 kW.
What is the altitude deration for the JD60-04FT4?
Rated power is available up to 8,400 ft (2,560 m) at ambient temperatures to 122F (50C). This excellent altitude ceiling makes the JD60-04FT4 suitable for virtually any installation in the western United States.
