Highlights from Diesel Dirt & Turf 2024

This year’s National Diesel Dirt & Turf Expo once again provided a range of machinery highlights, including several launches for the Australian market

Thousands travelled from across Australia to attend this year’s Diesel Dirt & Turf Expo (DDT) at Sydney Dragway from April 12-14.

The country’s largest construction expo was held over three days and, with over 150 exhibitors in attendance, the Earthmovers & Excavators team was on site to check out the latest and greatest equipment available for the earthmoving industry.

Here are some of the highlights from DDT 2024:

DDT Gold Sponsor Komatsu had one of the largest displays of machinery and technology at the event.

Two of Komatsu’s electric prototype excavators were at its 1,400 square metre site, with both pieces of machinery on display for the first time in Australia.

Providing quieter operation than diesel machines, the PC210LCE-11 hydraulic electric excavator and the PC33E-6 electric mini excavator are suited for indoor sites and congested residential and commercial areas.

Komatsu says both excavators are battery-powered and deliver zero emissions without comprising on productivity or comfort.

The PC33E-6 has a 17.4kW electric motor and an operating weight of three tonnes.

CJD Equipment

Continuing the theme of electric excavators, the Australian distributor of Volvo and SDLG – CJD Equipment – unveiled a brand-new Volvo ECR25 electric mini excavator.

CJD says the ECR25 provides the same performance as its diesel equivalent but releases zero emissions.

It has a two to four-hour run time depending on the application and provides quiet operation, which is beneficial to indoor sites and residential areas.

Capable of being charged to 80 per cent in less than an hour, the ECR25 can easily be recharged during lunch breaks.

Toyota Material Handling Australia (TMHA)

Displaying a variety of machines from Huski Construction Equipment, TMHA highlighted two key models of its Huski skid steer range, the 4SDK4 and 5SDK5.

Standard features on the skid steer range include its high lift capacity, load handling pedal control, a multiple safety interlock system, a shock reducing bucket feature and low vibration control levers.

The compact-sized 4SDK4 is the smallest skid steer in the Huski range with a height of 1.8m and a width of 900mm, making it easily transportable on a trailer.

The 5SDK5 is capable of lifting loads of 430kg and is the largest skid steer in the range that can be transported within a 3.5-tonne towing capacity, which means it is still able to be carried on a trailer.

Slightly larger than its 4SDK4 counterpart, TMHA says the 5SDK5 skid steer can also be used in tight access spaces and stored in garages as the machine is only 1.25m wide and 1.86m tall.

An official dealer of Hidromek, Striker, Dressta, Tigercat, Hyundai and Anaconda machinery in Australia, Onetrak used DDT to showcase its popular HMK600MG Hidromek grader.

With an 18,000kg operating weight, this grader is the largest model in Onetrak’s grader range.

It comes standard with a 3,710mm blade and a blade turning angle of 360 degrees, whilst producing 214 to 242 horsepower (160 to 180kW) with its Mercedes-Benz engine.

The HMK600MG can be used in many applications ranging from levelling and digging to trenching and snow ploughing.

Celebrating 20 years of the business in NSW, official Caterpillar dealer WesTrac launched a new Cat compact track loader on the first day of DDT to kick off the event with a bang.

The Next Gen Caterpillar 255 compact track loader replaces the first generation 259D3 compact track loader and is powered by a Cat C2.8T engine, which offers 74.3hp (55.4kW).

The 255 delivers class-leading lift height and delivers 36 per cent more tilt breakout when compared to its first-generation counterpart, WesTrac says.

Also on display was one of the first Cat construction machines sold in NSW by WesTrac – a 120H motor grader.

Shop In A Box from Continental. Image: Prime Creative Media


On display at Continental’s site was its Shop In A Box industrial fluid solution, which is sold as a turnkey workbench that replicates the capabilities of a hydraulic and industrial hose crimp shop for operators.

Available with the option of four different crimper models, the Shop In A Box is suited to both occasional users through to everyday users – depending on the crimper model chosen.

The crimper models have different crimp capabilities for various hose types, so a purchaser can choose the model that is suited to them.

The PC200i crimper model was of particular interest due to Continental’s patented CrimpIQ technology being integrated into it – connecting the PC200i to Bluetooth and a cloud.

Doherty Couplers & Attachments

Amongst a range of earthmoving machinery attachments, Doherty’s D-Lock tilt coupler was a drawcard.

Incorporating a precision-built actuator that ensures trouble-free operation, operators can tilt all attachments up to 180 degrees rather than having to move an entire machine.

Covering machines from one to 50 tonnes, the coupler has been designed with a compact and narrow body for greater visibility and performance.

Its patented DPL+ safety system comes standard on the D-Lock tilt range, which the company says it gives a range of benefits over other brands.

Colbrook Industries

Featuring a range of skid steer attachments, two highlights of Colbrook’s site was the SK drum mulcher DC Pro and the SK disc mulcher belt drive Pro X from Diamond Mowers, which it exclusively distributes in Australia.

Suited to loaders up to 75hp (56kW), the drum mulching attachment has a cutting width of 50 inches (127cm) and mulches trees or brush up to eight inches in diameter.

The belt drive disc mulcher is designed for contractors and mulching professionals with up 60 inches of cutting width and cuts up to 14 inches diameter of brush and trees.

With class-leading torque, Colbrook says the belt drive can recover twice as fast as other disc mulchers.

NSW distributor of construction and agricultural implements Ag-Pride showed a range of Berti mulcher attachments designed for excavators in the three to 10-tonne range.

The Italian-built range of mulcher heads is designed to cover everything from roadside vegetation management to pasture clearance.

The KX/SSL Berci hydraulic forestry mulcher was on display, suited to skid steers from 50 to 90hp (37kW to 67kW).

Ag-Pride says it comes with fixed-teeth rotor and can mulch vegetable residue, branches and standing plants up to 12 to 15cm in diameter.

Digga Australia

Digga Australia used its stand as an opportunity to showcase its new X-Series heavy duty 4-in-1 bucket.

Officially launched at DDT, the X-Series buckets are suited to large skid steer loaders and have upgraded dump and rollback angles.

Being used in the demo area, attendees got the chance to test out the bucket’s increased opening width and improved clamping force.


An Associate Sponsor of the event, XCMG displayed a wide variety of heavy machinery to attendees.

Its XC968-EV electric wheel loader was of interest for many, encompassing an operating mass of 18.8 tonnes and rated power up to 280kW (375hp).

The zero emissions electric model has a 3.2-cubic metre bucket capacity with a rated load of 5.8 tonnes.

Also catching the eye was a XDA45U articulated dump truck installed with an Allquip Water Trucks 33,000 litre tank.

This machine has a 41-tonne payload and is designed for use in mines, quarries, water conservation, harbours and construction sites.

Standing out with its blue-painted machinery, Kobelco showcased its newest excavators at the Expo, including the SK380SRLC-7 excavator – Kobelco’s heaviest short radius excavator to date.

Weighing in at 37 tonnes, the new model encompasses a 210kW (282hp) output and a six per cent higher torque than previous models.

Ideal for operators working on urban and residential jobsites, the construction machinery company says short radius machines are becoming increasingly popular due to ongoing requirements for roadworks and utility maintenance.

Kobelco says short radius machines benefit from a smaller working footprint, which means that they can access tighter working areas.

Steelwrist had quick couplers and tiltrotators on display. Image: Prime Creative Media


Steelwrist’s stand had two large excavators demoing its range of quick couplers, tilt couplers and tilt rotators.

Mounted on one of the excavators was displaying a double SQ60 quick coupler and tilt rotator combination. Steelwrist says the reason it was showcasing a double SQ quick coupler on one machine was to show its versatility in changing between different hydraulic work tools.

Normally, Steelwrist wouldn’t allow a breaker or hammer to be put under a tilt rotator, but in these cases an operator can disconnect the tilt rotator and pick up an attachment such as a hammer.

The SQ quick coupler under the tilt rotator is used on any types of attachment that needs to rotate, such as a bucket.
