When your excavator, skid steer, or compact track loader goes down, you lose the day. You cannot wait 3 weeks for a dealer appointment, but blindly trailering a machine across town before a single bolt is turned is just as costly.
Masterman Heavy Equipment Service LLC sends Robert Marecki directly to your job site in Schaumburg or anywhere across Chicagoland. He diagnoses the problem on-site. We perform field repairs when possible to get your machine running fast, and coordinate transport to our fully equipped Schaumburg facility for major engine, hydraulic, or structural overhauls.
Bobcat is our highest-volume brand. We work on skid steers, compact track loaders, and mini excavators across Cook and DuPage County. Minor hydraulic leaks and electrical faults we repair on-site. For major drive system failures or engine rebuilds, we utilize our fully equipped repair shop.
We service CAT mini excavators and compact equipment across Chicagoland job sites. If the dealer has no availability for weeks, we come to you for rapid field diagnostics, and handle major teardowns at our Schaumburg facility.
Case skid steers and excavators are common across construction and landscaping operations in the Chicago suburbs. We carry parts for common Case failures and repair these machines on-site.
We service New Holland compact equipment including skid steers and compact track loaders. If your machine is down on a site in Naperville, Aurora, or anywhere across the metro, we get there.
Takeuchi compact track loaders and excavators need a mechanic who actually knows the brand. Most shops in the Chicago area will not take them on. We specialize in Takeuchi and service these machines on-site across Chicagoland.
Kubota excavators, compact tractors, and utility vehicles show up on construction sites, landscaping operations, and commercial properties all across the Chicago suburbs. We service Kubota equipment on-site and repair Kubota engines inside other machines as well.

We start at your job site. We do not require you to blindly drop off a machine without knowing the issue. We diagnose the failure in the dirt and perform rapid field repairs when possible. When a major overhaul is required, we bring the machine back to our fully equipped service facility in Schaumburg, giving you the best of both mobile speed and heavy-duty shop capacity.
Dealers in the Chicago area run 2 to 4 week service backlogs. Your job site cannot wait that long. We schedule field diagnostics fast, and prioritize getting your machine back to work, whether that means an on-site fix or a streamlined in-shop repair.
You run a Bobcat and a CAT on the same site. Most mechanics know one brand well and guess their way through the other. Robert works on all the brands listed above and has hands-on experience with each one.
You call or text Robert directly. There is no dispatcher, no hold queue, and no one who needs to check with the shop before giving you an answer. You get a straight answer on the phone, every time.
We work with site superintendents who need a Bobcat running before their crew arrives at 7 AM. We work with independent contractors whose skid steer is their entire operation and cannot
afford two days of downtime. We work with general contractors managing multiple machines across active sites in Cook and DuPage County.
