WITH Caterpillar and Case-IH marketing 373kW (500hp) tractors, it was inevitable that New Holland would join the club.
It happened last week at the company¹s product launch in Perth with the release of the TJ500 articulated four-wheel drive tractor.
Powered by a Cummins QSX 15L engine, it is built off the same frame and components of the TJ450.
But it operates at 100rpm faster than the TJ450, has a larger air induction system, uses larger tyres, has improved hydraulics and uses a 24-volt starting system for improved starting in cold conditions.
It also has a huge 185 amp alternator which should eliminate hassles with modern lighting packages that include HID lamps.
The Cummins engine is linked to a 16-speed full powershift transmission with nine gears in the 4.8 to 12.8km/h working range. Speeds are spaced at 0.8km/h intervals with acceleration modulated for smooth starts.
In operation, you can use the auto-skip function to skip every other gear and accelerate up to 37km/h (depending on tyre size).
Standard features include a 216L/min hydraulic pump and hydraulic wet disc brakes and hydraulics can be increased to 356L/min through two independent pumps.
The disc brakes on the front and rear axles are cooled with filtered oil to provide better stopping power while a positive, integrated spring-applied parking brake engages automatically when the engine is shut off.
The frame, axles and drive train components are matched to the horsepower to handle big rigs.
Massive axle housings provide structural support while precision ground spiral bevel gear sets offer strength, durability and quiet operation.
Planetary input gears, bearings and final drives are lubricated with pressurized, filtered and cooled oil.
The centre-pull design has been retained to deliver power at the drawbar.
The drawbar is mounted near the articulation point at the centre of the tractor, giving the TJ500 a better pull angle for more efficient pulling power to tow wider implements.
Similar to other TJ models, the cab provides all operator comforts.
A total of 6.2 square metres of glass provides an expansive view while the auto comfort active suspension air-ride seat continuously monitors vehicle ride and automatically adjusts the dampening provided by the shock absorber.
