CP Repair · Mobile diesel mechanic · Preston, MDWe bring the
shop to you.
Heavy equipment, farm machinery and diesel trucks, repaired where they sit. One call to Collin and the service truck comes to your yard, your field or your job site.
What we fix
If it runs on diesel or hydraulics, call Collin.
From a skid steer on a job site to a combine in the middle of harvest, the repair happens where the machine stopped.
Heavy equipment repair
Excavators, dozers, loaders, skid steers and backhoes, fixed on the job site so the crew keeps working.
Farm equipment repair
Tractors, combines, sprayers and planters, repaired in the field when the season will not wait.
Diesel truck and trailer repair
Work trucks, dump trucks and trailers, serviced in your yard instead of waiting on a shop bay.
Hydraulic repair
Leaks, blown hoses, fittings and cylinders, the failures that stop a machine cold.
Diagnostics and electrical
No-starts, warning lights, wiring faults and the problems nobody else could find.
Preventive maintenance
Scheduled service in your yard, so the breakdown never happens in the first place.

Call or send the details
What the machine is, where it sits and what it did before it quit. A photo of the problem helps. Request service or call (410) 829-7982.
Collin comes to you
The service truck rolls out with the tools and the crane to your yard, your field or your job site, and the machine gets diagnosed right there.
Fixed where it sits
You get a straight answer on what is wrong and what it takes, then the repair gets done on site so the machine goes back to work.

Why mobile
Hauling it in, or fixing it where it sits.
A machine on a trailer is a machine not working, plus the haul, plus the wait. Here is the difference, side by side.
| Step | Hauling it to a shop | CP Repair comes to you |
|---|---|---|
| Getting it there | A trailer or a lowboy, a truck to pull it, and somebody’s day | Nothing. The service truck drives to the machine |
| Before anyone looks at it | It waits in line for an open bay | It gets looked at where it quit |
| Heavy parts | Pulled in the shop | Handled with the crane on the truck |
| Getting it back to work | Another haul home | It is already where it works |
| Who you talk to | A service writer | Collin, who does the work |
