As farmers and contractors seek more efficiencies, we see average horsepower climbing while implements get wider, longer or heavier. The biggest change in the last decade is the increase in tractor speeds.
It used to be the norm for the ‘old faithful’ Ford 4000 to rattle along at 30km/h; now everything off the shelf now runs at 40km/h, contractors favour 50km/h for road work and some manufacturers in the last three years have introduced, subject to local regulations, 60km/h rocketships.
So, it was always going to be inevitable that some regulatory body was going to take a long, hard look at the other side of the equation and decide if regulation was needed to bring these machines back to a safe controlled standstill: step forward the good old E.U.
New EU braking regulations will come into force in 2016 and include a number of new and higher requirements in tractor braking performance, compatibility, safety standards and stability. Of course, because most New Zealand tractors are sourced from Europe, these systems are likely to be part and parcel of the vehicles the importers bring to our shores.
Requirements of compatibility between tractor and towed vehicle have been included to ensure braking distances are shortened and the systems are optimised for towing and towed vehicles. As of 2016, anti-lock braking systems (ABS) will be mandatory on all tractors capable of 60km/h or more. There is also a move to make this regulation applicable to tractors with a capability of 40-60km/h by 2020.
So in the run-up to 2016, and the implementation of the new regulations, manufacturers are making big investments and engineering changes to their machines to bring them into line with these tougher requirements. A major challenge lies in the fitting of ABS to the hydraulic braking systems fitted to most tractors currently available, since ABS is, at the moment, only suitable for pneumatic systems.
Where will this leave NZ? Especially when there seems to be a ‘she’ll be right’ attitude to anything that looks like it will cost a few dollars?
The uprated tractors for the Euro market are likely to find their way to our shores with this technology already on board. NZ tractor and machinery importers and dealers will need to embrace the technology and sell their benefits to the customers.
Already, over the past few years, we are seeing more European style tipping trailers being sold, from a humble five tonnes to large tandem axle units weighing 12 tonnes and more. The same applies to feed wagons: as dairy operations get larger, so do feed wagons, as evidenced by a number of 16m3 units on the field days circuit.
These shouldn’t be on the road behind tractors weighing five to seven tonnes without proper braking systems, as the ‘tail wagging the dog’ syndrome is likely to occur. And let’s not forget the Kiwi favourite, the quick hitch – a lump of folded angle iron with a central pin, carried 1m behind the recommended towing point of the tractor (the axle) to move heavy trailers.
Get real; it’s time we embraced proper manufacturer-rated pick-up hitches to do the job. Then she’ll be right!
OPINION: With the 2024 edition of National Fieldays behind us, it would be fair to say that although the mood was positive – a plus, given the negative sentiment across the rural sector – you must wonder if this showcase format’s days are numbered.
OPINION: As 2022 is consigned to the history books and we trudge into 2023, it seems like a good time to look back at the decision by the NZ National Fieldays Society to move its annual event from June to December last year.
OPINION: As agriculture continues its march into the digital age - where farmers, paddocks, machines and inputs are all interconnected - one must wonder whether an individual or organisation could wreak havoc if they broke into operating systems.
Since Covid-19 reared its ugly head in early 2020, machinery manufacturers have faced and continued to face challenges and disruptions.
Alternatively powered vehicles, be they cars, utes or even tractors, never seem to be far from the news.
Avian flu getting into New Zealand's poultry industry is the biosecurity threat that is most worrying for Biosecurity Minister Andrew Hoggard.
The annual domestic utilisation of wool will double to 30,000 tonnes because of the edict that government agencies should use woollen fibre products in the construction of new and refurbished buildings.
Among the regular exhibitors at last month’s South Island Agricultural Field Days, the one that arguably takes the most intensive preparation every time is the PGG Wrightson Seeds site.
Two high producing Canterbury dairy farmers are moving to blended stockfeed supplements fed in-shed for a number of reasons, not the least of which is to boost protein levels, which they can’t achieve through pasture under the region’s nitrogen limit of 190kg/ha.
Buoyed by strong forecasts for milk prices and a renewed demand for dairy assets, the South Island rural real estate market has begun the year with positive momentum, according to Colliers.
The six young cattle breeders participating in the inaugural Holstein Friesian NZ young breeder development programme have completed their first event of the year.
