John Deere 555G Crawler Loader: Mid-Size 80 HP Turbo Track Loader
Produced through the 1990s, the 555G paired the JD 550G chassis with a turbocharged JD 4-cylinder diesel and a front hydraulic bucket - a productive mid-size track loader with hydrostatic dual-path drive, ~80 HP, and the bucket capacity for serious load-and-carry work.
Where the 555G fits in the JD crawler loader family
The 555G was the mid-size JD crawler loader of the G generation, built on the chassis platform shared with the 550G Crawler Dozer. Where the 550G carries a dozer blade, the 555G carries a front hydraulic bucket for digging, loading, and material handling. Same chassis, same hydrostatic dual-path drive, same JD 4-cylinder diesel platform - but turbocharged in the 555G to produce roughly 80 HP for better breakout force and faster cycle times.
The 555G sits between the 455G (compact-class loader on the 450 chassis) and JD's heavier dedicated wheel-loader line. For mid-size load-and-carry work, the 555G covers the slot where customers want a track loader rather than a wheel loader - confined-area work, soft ground, slopes, or applications where ground pressure matters.

Engine, hydraulics, and undercarriage
The 555G’s turbocharged JD 4-cylinder diesel powers the dual-path drive system, the implement hydraulic circuit (bucket lift, tilt, and clamshell on 4-in-1 configurations), and the auxiliary hydraulics. The turbocharger steps engine output up significantly compared to a naturally-aspirated JD 4-cylinder at the same displacement - more breakout force in the pile and more lugging response when the bucket hits resistance.
Bucket configurations included standard buckets in multiple capacities, 4-in-1 multi-purpose buckets with clamshell operation, and specialty buckets for forestry and demolition. Cylinder bore and stroke vary with bucket configuration.
Common service items on the 555G
- Hydrostatic pumps and motors: Drive pump rebuilds, drive motor rebuilds, charge pump, filter housings, case drain hoses.
- Turbocharger: Turbo rebuilds, oil supply and drain lines, charge-air piping.
- Hydraulic filtration: Suction strainers, return filters, charge filter, hydraulic oil.
- Undercarriage: Track chains, track shoes, rollers, idlers, sprockets, idler springs.

- Serial number. Match parts to the machine serial - running changes occurred through the 1990s production run.
- Engine serial. The turbo JD 4-cylinder diesel had running changes. Engine internal parts must match the engine serial.
- Turbocharger variant. Turbo part numbers can vary across the production run.
- Hydrostatic pump/motor variant. Drive pump and motor part numbers changed during production.
- Bucket configuration. Standard, 4-in-1, and specialty buckets have different cylinder configurations.
- Undercarriage configuration. Standard, narrow, and LGP variants existed.
- Cab vs. ROPS canopy. Glass, A/C, and door parts differ.
Why the 555G remains a productive track loader
The 555G hit a productivity sweet spot in the mid-size track loader segment: turbo power for breakout force and fast cycle times, hydrostatic dual-path for maneuverability, no emissions aftertreatment to service, and chassis commonality with the high-volume 550G dozer. Parts availability is strong because both machines share much of the same drivetrain and undercarriage.
Maintenance priorities on a 555G: clean cool hydraulic oil, on-schedule filter changes, turbocharger oil supply integrity, undercarriage replacement as it wears, and engine rebuilds when wear demands. Broken Tractor maintains parts coverage across the 555-series and the broader JD crawler loader family, available at Broken Tractor.
