Case CX19D Mini Excavator: 2022+ 1.9-Ton D-Series Compact
The Case CX19D is a 1.9-ton D-Series mini excavator introduced in 2022. With a retractable undercarriage option for through-the-gate access, it’s purpose-built for landscape, plumbing, irrigation, and residential utility work where larger machines won’t fit.
Where the CX19D fits in the Case excavator line
The CX19D is a 1.9-ton class D-Series mini excavator, sitting in Case’s compact excavator range alongside smaller models like the CX17C and larger compacts like the CX25EV. It’s a tight-quarters machine - through-the-gate access with the retractable undercarriage, rubber-track flotation that won’t tear up finished turf, and just enough reach and dig depth for residential utility, irrigation, plumbing, and landscape work.

Engine, hydraulics, and drivetrain
The CX19D runs a small Tier 4 Final compact diesel into a hydrostatic dual-path drivetrain with a rubber-track undercarriage. Boom, dipper, bucket, swing, and propel functions run from a single-section main hydraulic pump with electrohydraulic or mechanical control depending on configuration.
The retractable undercarriage option is the CX19D’s signature feature: tracks retract to fit through standard residential gates, then extend out for stable digging. That trade-off - access vs. stability - is what makes the 1.9-ton class viable for backyard and tight-site work.
Common service items on the CX19D
- Engine internals: Compact Tier 4 Final diesel - pistons, rings, sleeves, head gaskets. Common-rail injection.
- Tier 4 Final aftertreatment: DPF service intervals and regeneration behavior, DEF tank and dosing module, SCR catalyst, EGR cooler service.
- Fuel system: Common-rail injectors, lift pump, primary and secondary filters with tight water-separator standards.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler (on turbo builds), hoses, belts.
- Hydraulic system: Boom, dipper, bucket, and swing cylinder seal kits, main pump rebuild, electrohydraulic control valves, hoses.
- Boom and dipper: Pin and bushing service at every joint, bucket pins, thumb attachment hardware, quick coupler service.
- Undercarriage: Rubber track inspection and replacement, rollers, idlers, drive sprockets, recoil springs.
- Swing system: Swing motor and reduction gear service, swing bearing inspection, swing brake.
- Electrical / ECU: Engine ECU, instrument cluster, sensors, harness, telematics module on equipped units.
- Cab glass and wiper: KHN16820 24-inch wiper blade, KHN3046 front lower glass, and KHN2632 front upper glass cross-fit across Case and Link-Belt excavators.
- Operator station: Seat, joystick controls, pedal linkage, instrument panel, cab HVAC.

Need a part for your Case CX19D Mini Excavator?
Aftertreatment components, common-rail fuel parts, and hydraulic seal kits are the highest-turn items on a CX19D. Call our parts team with your serial number and we’ll match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the machine serial - the CX19D had running changes during production.
- Engine serial. Engine internal parts must match the engine serial number.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension - measure before ordering.
- Tier 4 emissions revision. DPF and DEF/SCR components saw revisions during production - confirm by serial.
- Engine ECU calibration. Common-rail injectors and ECU sensors are calibrated to specific build years.
- Bucket and quick coupler. Quick-coupler interface varies - confirm before ordering attachment-side hardware.
- Undercarriage variant. Standard vs. retractable undercarriage affects roller, idler, and track part numbers.
Why the CX19D still earns a paycheck
The Case CX19D is sized for compact-excavator duty cycles where a 1.9-ton machine is the right tool - residential landscape, utility, irrigation, plumbing, and any tight-quarters digging where larger excavators won’t fit. Modern Tier 4 Final emissions compliance, compact footprint, and rubber-track flotation suit residential and contractor work where a wheeled or larger tracked machine would mark up turf or fail to fit through the gate.
Maintenance priorities on a CX19D: clean fuel and tight water separation for common-rail injection, DPF regen behavior tracking, hydraulic oil at temperature with clean filtration, rubber-track tension and wear monitoring, and pin / bushing service at every working joint. Broken Tractor maintains parts coverage across the Case mini excavator family.
