What the 4.3 Profarm is Built For
The 4.3 ProFarm excels across the full range of agricultural earthmoving applications:
• Farm dam construction — cutting, hauling, and placing fill to shape a new dam wall or enlarging existing storage
• Paddock levelling and land forming — removing high spots and filling low areas for improved drainage and productivity
• Drainage earthworks — forming open drains, diversion channels, and irrigation infrastructure
• Rural road formation — cutting in farm tracks and property access roads
• Land clearing and topsoil stripping — preparing paddocks for cultivation or revegetation
The ejector mechanism is the key advantage over a conventional open-bowl scraper in Australian clay conditions. When sticky material clogs a bowl, productivity collapses. The hydraulic ejector plate clears the bowl completely on every cycle, maintaining consistent load volume and eliminating the manual clean-out stops that cost time and money in heavy soils.
Hitch Options
The 4.3 ProFarm is offered with our Uni-Hitch system as standard, allowing the machine to be coupled and uncoupled from the tractor quickly without manual intervention. Ball and socket hitch, and cushion hitch are available as optional extras — allowing you to configure the machine to suit your tractor and your operation.

Build Quality
The 4.3 ProFarm is built on a fully welded chassis using pressed and fabricated components and premium Australian steel throughout. Like every machine in the O’Bryan range, it is manufactured in our Berndigo workshop, which means parts are local, service is accessible, and warranty is backed by a team that understands Australian farming conditions.
Tractor Requirements
The 4.3 ProFarm requires a minimum of 300HP. It is designed to pair with mid-to-high horsepower agricultural tractors — Case IH Magnum, John Deere 8 Series, New Holland T8, and comparable platforms are commonly used. Contact our team to discuss the best configuration for your specific tractor and application.
4.3 Profarm Ejector Scraper
Built for Farming
The O’Bryan 4.3 ProFarm is our mid-range ejector scraper, a multi-purpose machine engineered specifically for Australian land owners, farmers, and seasonal contractors.
With a 12 cubic metre heaped bowl capacity and 13-foot (3,980mm) cutting edge, the 4.3 ProFarm delivers real earthmoving performance in a package that works efficiently with tractors in the 300HP+ range.
It is the right machine for the Australian farming operator who needs to move serious dirt without running a full civil fleet.

Frequently Asked Questions
The 4.3 ProFarm requires a minimum of 300HP. For best performance in harder soils or on steep grades, higher horsepower is recommended. Contact our team for a recommendation matched to your tractor and terrain.
The 4.5 HD range is engineered for heavy civil and mining applications — larger bowl (17m³), 14-foot cut, and 450HP+ requirements. The 4.3 ProFarm is designed for agricultural operations where a 300HP-range tractor is the prime mover and versatility across farm tasks matters alongside capacity.
Yes — farm dam construction is the most common application for the 4.3 ProFarm. The ejector mechanism is specifically valuable in the clay soils that most Australian farm dams are built in, as it prevents bowl packing and keeps cycle times consistent throughout the job.
The 4.3 ProFarm is built for Australian conditions including seasonal wet. The 14.00/24 tyres provide good flotation in soft ground. Ejector scrapers as a class perform better in wet sticky material than open-bowl scrapers because the ejector clears material rather than relying on gravity dump.
Every O'Bryan machine comes with a 2-year manufacturer's warranty backed by our Swan Hill workshop.
Yes — an auto greaser is available as an optional extra. It reduces daily maintenance time and extends wear component life, particularly in dusty or abrasive conditions.
