A breakdown costs more than the repair.

Every hour a machine sits is an hour a crew is standing around or a field is not getting worked. The job is to get you running again, not to book shop time.

Tell us what it is doing

Call, text a photo of the display, or fill out the form. Codes on the screen, noises, when it started. The more we know, the more likely the right part is already on the truck.

We drive out and diagnose

Laptop on the machine, live data, real fault codes. You get told what is actually wrong and what it costs before any wrench turns.

Fixed on site where possible

The truck carries a crane, a welder and air, so most hydraulic, engine and electrical work happens right where the machine sits.

What we do

Field service for equipment that does not move easily.

Diagnostics and electrical

Dealer-level scan tools for engine, hydraulic, transmission and aftertreatment modules. Half the calls that look like a dead engine turn out to be a chafed harness or a four cent connector, and finding that is the whole job.

  • Fault code diagnosis
  • No-communication faults
  • Harness and connector repair
  • Sensor replacement
  • Parasitic battery draw
  • Telematics online or off

Hydraulics

The dominant failure on off-road equipment. Pumps, valves, cylinders and hoses, plus the leaks nobody can find.

  • Pump replacement
  • Cylinder reseal
  • Boom drift
  • Hose fabrication
  • Slow or dead swing

Engine, drivetrain and undercarriage

Mechanical work from a hard start through a full in-frame rebuild, plus final drives, travel motors and track work.

  • Injectors and fuel system
  • Turbo replacement
  • Cooling and overheat
  • In-frame rebuild
  • Final drive rebuild
  • Track tension and rollers

Emissions, welding and maintenance

Tier 4 aftertreatment recovery, on-site welding off the truck, and scheduled service so the fleet stops surprising you.

  • Forced and parked regen
  • DEF and SCR faults
  • EGR cooler replacement
  • Derate recovery
  • Bucket and frame welding
  • Scheduled PM service

Brands and machines we work on.

Construction, agricultural and material-handling equipment, plus the diesel engines inside them. If the machine is not listed, it is still worth a call.

JRD Equipment Service LLC is an independent repair business. It is not affiliated with, authorized by, or a dealer for any of the manufacturers named here. Brand names identify the equipment we service.

Dealer software, independent rates.

Most of what separates a dealer from an independent is the laptop. Parked regens, injector trim, ECM programming and parameter edits all need the factory platform. We run them, so the machine does not have to go to a dealer for a software-gated fix.

On emissions work: aftertreatment repairs and parameter edits are performed to manufacturer specification and within EPA regulations. We diagnose, regen, repair and replace emissions systems. We do not delete or defeat them.

JRD Equipment Service Ford F-550 field service truck equipped with a boom crane, welder and air compressor

The shop drives to the machine.

Boom crane Lifts final drives, pumps and counterweights on site, so heavy components come off in the field.
Welder and generator Cracked buckets, broken brackets and fabrication handled where the machine sits.
Air compressor Impact tools and air service without hunting for shop power on the jobsite.
Diagnostics and tooling Factory scan platforms, hydraulic test gear and a stocked service body.

Photos help more than words

Text a picture of the fault code on the display, the data plate, or whatever is leaking. It often settles the diagnosis before anyone leaves the yard.
