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.

Scheduled servicing and logbook maintenance for trucks and earthmoving equipment
Hydraulic diagnostics, hose making and cylinder repairs
Attachment fitting, bucket repairs and custom fabrication
Pre-purchase inspections and machine preparation before delivery

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.

Frequently asked questions

Answers specific to the Smeaton Grange branch.

What are the opening hours at STM Smeaton Grange?

Sales and parts are open 7:00am to 5:00pm Monday to Friday and 8:00am to 12:00pm on Saturday. The service workshop closes at 4:30pm on weekdays and is closed weekends. All departments are closed on NSW public holidays.

How late can I drop off a truck for service?

Truck service at Smeaton Grange is open until 8pm Monday to Friday, which is later than most dealerships in the area, so you can bring a truck in after a day’s work rather than losing a shift. Saturday service hours are 7am to 12pm. Machinery service operates separately, 6.30am to 4.30pm on weekdays.

Can I buy parts for a machine I did not buy from STM?

Yes. The parts counter at Smeaton Grange is open to everyone, whether or not the machine came from us. We carry genuine parts for the brands we represent and can order in most items we do not hold in stock. Call the branch on (02) 4647 4488 with your machine model and serial number and we will confirm availability.

Where do I park a truck or float when visiting?

The Dunn Rd site has hardstand access suitable for trucks and floats. If you are delivering or collecting a machine on a float, call ahead on (02) 4647 4488 so we can direct you to the right gate.

Where is the STM Sydney branch and what is on site?

STM Head Office is at 20-26 Dunn Rd, Smeaton Grange NSW 2567, in the Smeaton Grange industrial area just off Narellan Road and a short drive from Camden, Narellan and Campbelltown. Sales, service, parts, attachments and finance all operate from this one site, so you can look at a machine, order parts and talk through finance in a single visit.

Do you offer finance on trucks and machinery?

Yes. Equipment finance can be arranged through the Sydney branch for both new and used trucks and machinery. Speak to the sales team on (02) 4647 4488 and they will walk you through what is involved.

Can I collect parts on a Saturday?

Yes. The parts counter is open Saturday 7am to 12pm. Note that the parts warehouse is closed on Saturdays for bulk pick-ups and deliveries, so large or palletised orders need to be collected Monday to Friday before the warehouse closes at 4pm. Smaller counter orders are fine on a Saturday.
