Rebuilt Raba-Steiger tractor combats Europe’s flooded fields and reduces fuel consumption by 25 to 30 per cent
Hungarian-modified Huntractor HT300 is equipped with an Allison 4500 fully automatic transmission for efficient, reliable performance.
Szabadegyháza, Hungary – A Raba-Steiger agricultural tractor has been modified by Hungarian specialist, Huntractor Ltd, in a rebuild that touched almost all major vehicle components. This included the replacement of the manual transmission with an Allison 4500 model fully automatic transmission.
Due to high levels of precipitation in South and Central Europe in 2014, agricultural machines across the continent were stuck in the mud. But with its Allison fully automatic transmission, the Huntractor HT300 did not experience the same downtime. In fact, it was often sent to retrieve stranded vehicles, which it did without becoming mired down itself.
Towing cultivating discs through the soil is a very challenging process depending on the quality of the land. The Huntractor HT300 was designed to shift smoothly during loaded operation in order to be most effective. Where the manual transmission left parts of fields unprocessed due to gear hesitation and jerky shifting, Allison’s Continuous Power Technology™ assures uninterrupted power to the drive wheels, improving reliability on water-logged soil and any other difficult surfaces. The Allison, a perfect match with the Cummins engine, was easily integrated into the vehicle allowing for a robust drivetrain solution.
Huntractor Ltd’s Director, Istvan Ratkai, was very satisfied with the machine. According to Ratkai, with the Allison transmission transferring full power to the wheels, operation was smooth and continuous, and the tractor could achieve maximum performance. “The new driveline met our operational expectations, with the tractor’s cultivating discs working continuously at maximum depth without gaps and without affecting the vehicle’s average 11 kph to 13 kph speed,” he said.
Compared to the original driveline, the Allison-equipped Huntractor HT300 achieved a 25 to 30 per cent reduction in fuel consumption. The HT300 was tasked with deep-loosening. Dragging loosening-plows through flooded land is the same as operating with a heavy load, yet the tractor launched smoothly and performed without any jerks to produce a uniformly tilled field.
Allison patented torque converter technology protects the driveline and the CAN controller moderates engine torque based on other system data and operating conditions. This ensures the original vehicle parts are not overworked – crucial to keeping maintenance costs low and extending the vehicle’s life.
The Huntractor HT300 was first introduced in Hungary in September 214 at the Babolna Agricultural Expo.
