New range with old name

By Peter Hill

THE Steiger name returns to the bonnet of high-horsepower four-wheel-drive tractors after an absence of eight years – with the launch of the 9300-series articulated steer models from Case.

The tractors – four models ranging from 235hp to 400hp – feature increased engine power, stronger drivetrain components and uprated hydraulics.

Output from the Cummins engines in the top three versions goes up by between 10hp and 25hp as a result of continuing demand for more power.

Revised pistons and turbo systems contribute to the increased outputs, and there is a variable fuel injection timing system on the largest capacity motor.

There are new axles for the 360hp 9370 and 400hp 9380 to cope with the extra power and higher operating weights; and hydraulic system pressure has been raised to cope with the 50ft-plus cultivators and seeders used by North American growers.

Provision for fitting wafer ballast weights front and rear allows owners to set-up their tractors for high traction with a light tread – down to 6psi with duals fitted – and there are a few changes in the cab to make life more comfortable for drivers spending long hours on their machines.

One result of boosting power output of the range-topping 9380 is that it is no longer available with three-point lift linkage – at least for the time being.

"There is no official standard for a linkage to cope with this level of power," notes Kelly Kravig.

That will present few problems for North American sales but, in Britain, the tractors are more often used with linkage, notes UK agricultural sales manager Peter Stead.

"That means UK buyers wanting to use mounted equipment will be limited to the 360hp 9370 which is less powerful than the 9280 we have been selling for the past three years," he says.

UK specification tractors come with a 12-speed powershift transmission (a new gearbox giving 24 speeds but manual operation is optional), with forward-reverse selector and pulse-type gear lever mounted on the control and instrument panel positioned to the right of the driver.

Steering is by articulated chassis in all cases, but "row-crop special" versions of the 9330 and 9350 have a steerable front axle giving a tighter turn.

It also allows fine steering corrections without running over crop rows or transferring excessive tail-wagging movement to any implements.
