We bring the shop
to your equipment

Mobile diesel and heavy equipment repair for fleets, contractors, and equipment owners. Preventive maintenance, diagnostics, hydraulics, air brakes, hose making, and field welding, done at your yard or job site.

What we do on site

Preventive maintenance

Scheduled service by hours, miles, or calendar, performed at your yard so your equipment is not sitting in someone else's parking lot.

Diagnostics and electrical

Multi-brand diagnostics, no-start and charging problems, sensors, wiring, and aftertreatment faults.

Hydraulic hose, made here

We build and install replacement hoses on site with our own crimper and dies. A blown hose does not have to end the day.

Air brakes and chassis

Brakes, air systems, suspension, steering, and driveline work on trucks and vocational bodies.

Field welding and fabrication

Chipper and frame repairs, cutting edges, brackets, and trailer work with the welder that rides on the truck.

Inspections

Annual inspections for the trucks that need them, handled at your yard on a schedule you can plan around.

Equipment we work on

  • Vocational trucks
    Dumps, grapple and knuckleboom trucks, chip trucks, flatbeds, service bodies
  • Tree and landscape equipment
    Chippers, stump grinders, aerial lifts, loaders, mowers

  • Not sure?
    Send a photo of the data plate and we will tell you straight whether it is in our lane.

Maintenance programs for fleets

If you run three trucks or thirty, a scheduled program beats calling around after a breakdown. We set intervals by how the equipment actually gets used, keep a record for every unit, and tell you what is coming before it fails.

Every unit tracked

Hours, service history, and photos for each machine, so you can see where the money is going.

Findings ranked

Fix now, watch, or plan for it. You decide with the information in front of you.

Scheduled, not squeezed in

Program customers get first call on the schedule, including when something breaks.

Who you are calling

Lead Technician

Jules Beresford

Jules is a fully certified automotive repair technician and has been a friend of Apollo's since college. He handles the diagnostics and the wrenching, and he is the one who shows up at your yard. [Years in the trade and the equipment he has spent the most time on, for Jules to fill in.]

CEO, COO, CMO

Apollo O'Neil

Apollo has run O'Neil's Tree Service in Palm Harbor since 2008, so he knows what it costs when a truck or chipper is down on a Monday morning. He is an ISA Board Certified Master Arborist and an NCCER certified crane operator. Fleet owners kept asking him who they could trust to work on their equipment, and good mechanics are hard to find and harder to get on the phone. That is why King Pin Diesel exists.
