Precision performance

The eighth of May marked the spectacular Australian launch of Yanmar Tractors at the Novotel-Forest Resort in Creswick.

The Yanmar Company, Japan, has produced top quality agricultural machinery for almost half a century, anticipating and meeting the demands of farmers and contractors across the world.

Under the spotlight at the Yanmar launch was the popular and fuel-savvy 90hp EG907 model, a four-wheel drive, four-cylinder tractor with hydrostatic power steering and new-style TNV electronically controlled direct-injection engine. 

The EG907 is designed to give maximum efficiency and control, allowing the operator to concentrate on the job at hand. 

The TNV engine controls fuel consumption at 1/100-second increments and features a mono-plunger (MP4) fuel injection pump, four valve intake/exhaust and central injection.   

Dual Mode Control for high rpm needs such as rotary tiller work, and low rpm needs like spraying, ensures stable power output even under sudden load increase, drawing maximum performance from the tractor.

HMT continuously variable transmission combines the superior performance of step-free hydrostatic transmission and the high power transmission efficiency of planetary gear operations.  It provides smooth speed changes from standstill to maximum and back, providing optimum performance at the most appropriate speed.

Automatic implement control employs a tilt-speed sensor to quickly detect any tilting of the tractor on rough ground, and quickly adjusts the implement to level.

Speed maintenance control maintains the running speed set for the main gear, even when load resistance increases.  When changing loads during work, the implement is automatically raised and lowered and pulling power remains constant.

The EG907 offers the superior ergonomic comfort you would expect from a tractor of this design standard, with easy-to-read gauges, 360 degree panoramic vision and adjustable seating suspension to minimise fatigue.
