Truck and machinery sales in the Macarthur region
STM’s Smeaton Grange headquarters has served operators across South West Sydney since the business moved to Dunn Road, and it is still the largest of our three branches. If you are looking for truck and machinery dealers near Camden, Campbelltown or Narellan, this is the yard to walk: forty-plus machines on the ground, a six-bay workshop, and a parts counter stocked for every brand we sell.
Servicing Camden, Campbelltown and Narellan
Our service department handles scheduled maintenance, warranty work, safety inspections and heavy repairs on trucks, excavators and telehandlers. Two mobile field service vehicles run daily across the Macarthur and Wollondilly areas, so a breakdown on site does not have to mean floating a machine back to the workshop.
Parts, attachments and finance under one roof
The parts counter carries genuine filters, undercarriage, ground engaging tools and workshop consumables, with same-day pick-up on most stocked lines and overnight freight to regional NSW. Our finance team works from the same building, so an approval on the machine you have just walked around is usually turned around inside a day.
Family-owned since 1976 – the same team that sells you the machine is the team that services it.
Head office is a five-minute drive from the M31 Hume Motorway via Narellan Road, with truck access off Dunn Road and customer parking at the front of the building. Sales staff are on the yard from 7:00am if you need to be on site before your day starts.
