80 kW Tier 4 Final mobile trailer diesel generator built by Blue Star Power Systems. John Deere 4045HFG04 four-cylinder engine, Stamford UCI274C alternator, DSE DCP7310 controller, 250-gallon integrated fuel tank.
The Blue Star JD80-03FT4MP is an 80-kilowatt EPA Tier 4 Final mobile trailer diesel generator powered by the John Deere 4045HFG04 — a 4.51-liter, four-cylinder turbocharged and charge-air-cooled engine. It shares the same engine block and trailer footprint as the JD60-04FT4MP, with a higher-output calibration and a UCI274C alternator stepping up from the UCI224 frame class.
Blue Star Power Systems mounts the 4045HFG04 on an aluminum road trailer with a 250-gallon integral fuel tank, pairing it with a Stamford UCI274C alternator and DSE DCP7310 controller. At 8,850 lbs, the JD80-03FT4MP adds only 150 lbs over the JD60 for a 20 kWe gain — an efficient increment within the same platform. The 8,400 ft deration ceiling at 122°F is consistent with the JD60, reflecting the shared engine architecture.
The 4045HFG04 in the JD80-03FT4MP operates at a higher load density than in the JD60-04FT4MP, with fuel consumption rising from 4.82 to 6.05 gph at full load. The identical 214.5 × 90 in trailer dimensions make these two models footprint-compatible — a JD80 can occupy the same pad or transport configuration as a JD60, and the decision between them reduces to load requirement and fuel economy. For loads in the 60–80 kWe range, the JD80 rated at 100% provides better head room and thermal margin than a JD60 running at or above 90%.
70–80 kW temporary or standby power at construction, commercial, utility, or municipal sites
Sites up to 8,400 ft elevation at ambient temperatures to 122°F
Projects where the 214.5 × 90 in footprint is established and the JD60 is insufficient
Single-phase or three-phase loads at 120/240V, 120/208V, or 277/480V
Transition point before the Volvo Penta VD-series: the VD100-04FT4MP at 100 kWe uses a larger 230.5 × 90 in trailer platform with a 24V starting system and 250-gal tank
The JD80 and JD60 share the same 4045HFG04 service schedule — oil, fuel filters, and SCR system inspection intervals are identical. For the JD80, running at higher load density, annual full-load testing is particularly important to maintain DPF regeneration cycles. DEF quality management applies identically to both models. One practical note: verify the UCI274C alternator frame clearance when transitioning a site from JD60 to JD80 — the UCI274 is physically larger than the UCI224 and wiring harness lengths should be confirmed if the generator room is tight.

Frequently Asked Questions
What engine does the JD80-03FT4MP use?
The John Deere 4045HFG04 — a 4.51-liter, four-cylinder turbocharged and charge-air-cooled diesel. This is the same engine block used in the JD60-04FT4MP; the 80 kWe output is achieved through a higher-output calibration of the same 4045 platform rather than a different engine. Both models share identical trailer dimensions (214.5 × 90 in) and the 3.8-gallon DEF tank. EPA Tier 4 Final compliance uses SCR/DOC aftertreatment. Rated power is available to 8,400 ft (2,560 m) at 122°F (50°C).
What controller does the JD80-03FT4MP use?
The DSE DCP7310 Digital Control Panel, with CAN Bus J1939 engine communication, digital metering, RS-485 interface, 8 programmable contact inputs, 10 contact outputs, and NFPA 110 Level 1 compatibility. The panel is cULus Listed and CE Approved with IP 65 ingress protection (with supplied gasket). A 12V battery system and battery charger are included. The JD80 uses a UCI274C alternator — a step up from the UCI224F in the JD60 — which changes the frame class at commissioning.
How does the JD80-03FT4MP compare to the JD60-04FT4MP, and what alternator change is involved?
The JD60-04FT4MP and JD80-03FT4MP use the same 4045HFG04 engine on the same 214.5 × 90 in trailer footprint, separated by 150 lbs in shipping weight (8,700 vs 8,850 lbs) and a full alternator frame step: the JD60 uses a UCI224F (UCI224 frame) while the JD80 uses a UCI274C (UCI274 frame). The UCI274 series is the next frame class up in Stamford's product line. Fuel consumption at 80 kWe full load is 6.05 gph vs 4.82 gph for the JD60 — a 25% increase for a 33% output gain, reflecting the more aggressive engine calibration. Both require DEF.
What are the fuel capacity and runtime of the JD80-03FT4MP?
The JD80-03FT4MP carries a 250-gallon integral fuel tank. At full load (6.05 gph), runtime is approximately 41 hours. At 75% load (4.61 gph), runtime extends to approximately 54 hours. The 3.8-gallon DEF tank requires refill approximately every 18 hours at full load. Combustion air draw is 226 CFM; ventilation air requirement is 9,717 CFM. The 214.5 in trailer length and 8,850 lb weight are tow-capable with a rated 1-ton pickup or tractor.
