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 - Compact construction
Skid steers, mini excavators, track loaders, telehandlers
- Trailers
Lights, brakes, bearings, decks, couplers - Hydraulics
Hoses, fittings, cylinders, pumps, PTO systems - 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
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.]
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.
