Gillette SPJD-600
60 kW standby · Diesel · Liquid-cooled
60 kW stationary diesel standby generator with John Deere engine. Made-in-USA commercial diesel unit with DSE controller and Stamford or Marathon alternator.
The Gillette SPJD-600 is a 60-kilowatt stationary diesel standby generator built on John Deere's 4.5L turbocharged inline-4 platform. Like all Gillette units, it combines name-brand components (John Deere engine, Stamford or Marathon alternator, DSE 7420 MKII controller) assembled and factory load-tested in the USA.
At 60 kW diesel, this serves smaller commercial applications where natural gas is unavailable or where diesel is required by code: telecom sites, pump stations, remote municipal infrastructure, and small commercial buildings without gas service.
We service SPJD units at remote pump stations and telecom sites where the John Deere engine is the same platform we maintain on Kohler REOZ units. The DSE 7420 MKII controller is straightforward — no proprietary software or dealer-locked diagnostics. For customers with multiple generator brands, Gillette's use of standard components simplifies their maintenance program.

Frequently Asked Questions
What engine is in the Gillette SPJD-600?
A John Deere 4045 series — 4.5L turbocharged inline-4 diesel at 1800 RPM, the same proven engine family used in Kohler's 60-100 kW REOZ standby generators. Parts are available through John Deere's dealer network.
How does this compare to a Kohler 80REOZJF?
Similar John Deere engine platform at 60 kW vs 80 kW. Gillette uses a Stamford or Marathon alternator and DSE controller vs Kohler's proprietary components. Kohler has a stronger local service network in our territory.
What voltage configurations are offered?
Per Gillette's catalog suffix codes: 1-phase 120/240V (#1-1), 3-phase 120/208V (#3-2), 3-phase 120/240V (#3-3), 3-phase 277/480V (#3-4), and 3-phase 600V (#3-16). A switchable voltage selector option is also offered for 3PH 208/480 and 1PH 120/240.
What fuel tank options?
UL-142 double-wall sub-base fuel tanks are offered in multiple capacities; runtime depends on tank size and load. Specify NFPA 110 fuel supply provisions for Level 1 systems.
