The quad safety bar uses compressed gas and an electronic control system to offer fully automated, pneumatic roll-over protection.
An evolution of ATV and quad rollover protection, the AR quad safety bar uses compressed gas and an electronic control system to offer fully automated, pneumatic roll-over protection – with full deployment in less than 250 milliseconds.
As well as offering ‘active’ protection, the system also uses positional sensors to deliver passive information to the rider, using visual and audible signals to alert that the machine is reaching a stage where stability is about to be compromised.
The protective structure is a triangular tubular structure mounted to the rear carrier and the towbar, that in normal use sits lower than the rider, so does not raise the machine’s centre of gravity. If activated, the structure telescopes vertically and laterally, locking out mechanically at full extension and creating a ‘safe zone’ under the machine.
The manufacturer claims that the device will stop the machine rolling beyond 90 degrees from vertical, preventing a full rollover, while at the same time reducing any consequential damage.
Built by Spanish manufacturer Air Rops, the system is said to be compatible with most ATVs with independent suspension and meets regulatory standards, being certified by SGS, CE-marked and type approved by external notified bodies.
The overall design also meets OECD standards for agricultural tractors and ISO 3471 for machines with a mass of 300 to 5,000kg.
Massey Ferguson has announced a strategic supply partnership with International Tractors Limited (ITL), a manufacturer of low-horsepower and compact tractors, with recognised brands such as Sonalika and Sollis, to expand its portfolio with a new tractor range.
With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.
The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.
In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.
Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.
Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”
Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.

Becoming the norm in the automobile industry, but much less so in agriculture, Dutch self-propelled sprayer manufacturer Agrifac has developed a diesel-electric version of its Vanguard 55.
Building on the success of the existing Massey Ferguson 7S series, ahead of the upcoming EIMA Show, the manufacturer has announced the arrival of its new MF 7S MARK 2 range, offering six choices from 170 to 245hp, positioned between the current MF 7S and the MF 8S Xtra series.
French manufacturer Pichon has expanded its SV slurry tanker range with the launch of two new models.
In farming there are external factors that can influence behaviour of a whole herd, such as a bad weather event, triggering false positive heat detections or health attentions.
For Canterbury dairy farmer Cameron Henderson, supporting Meet the Need comes down to a simple question: how can the success of New Zealand farming benefit more than just those within the industry?
Fonterra board members are in line for a pay rise of around 3%.
Dairy processors are ready to further boost New Zealand’s export earnings but want the incoming government to match their ambition with good policy.
Massey University is best placed to solve the “problems” facing the dairy industry, says vice chancellor, Pierre Venter.
Synlait's longest serving employee – a man who joined the Canterbury-based milk processor even before it began processing milk – is now its newest executive.
OPINION: It seems Canterbury processor Synlait is still in the doldrums.
OPINION: Get offside with New Zealand First leader Winston Peters at your own peril.
