Case offers a sneak preview of new Maxxum at Ploughing
Farmers on the Continent will have to wait until Agritechnica in November to see them, but the Farming Independent can reveal that Case IH will be taking their new Maxxum CVX Efficient Power tractors to the National Ploughing Championships in Laois next week. Ploughing punters will see Case IH present three new models with continuously variable transmissions in the Maxxum Efficient Power series.
The move extends the firm's CVX offering to four-cylinder tractors, with the Maxxum 110 CVX, 120 CVX and 130 CVX representing the latest all-purpose tractors for the widest range of tasks featuring powerful engines and comfortable cabs. "These models follow the trend in continuously variable transmissions and extend our CVX offering in the medium power class with four-cylinder engines", says Vincent Hazenberg, product manager responsible for the Maxxum series at Case IH.
The Maxxum CVX models are equipped with proven CVX transmissions with double-clutch technology. These transmissions operate completely continuously between zero and 50kph and offer high overall efficiency in two mechanical operating ranges. Hydraulic power is available uniformly across the whole speed range of the tractor and requires less than 25pc of total power output.
Meanwhile, 50kph Eco Speed is achieved at a reduced engine speed of 1,750 rpm (40kph at 1,600rpm). The gear change between the two operating ranges takes place automatically using the double clutch.
The double-clutch technology ensures that frictional losses are minimised for maximum efficiency. Maxxum CVX tractors will be equipped with Case IH Automatic Productivity Management (APM), a system already proven with the larger Case IH tractors. APM automatically reduces engine speed if less power is required. Maxxum tractors will also feature an active stop control system.
The new Maxxum CVX tractors will be powered by four-cylinder engines which have a capacity of 4.5 litres. All models feature electronic common rail injection. The engines deliver a real power boost – 10pc higher performance at a reduced engine speed of 1,900 rpm.
This enables a noticeable reduction in fuel consumption. Efficient Power means that each engine has the Case IH SCR system (Selective Catalytic Reduction). They are optimised for efficiency so that maximum torque is reached at an engine speed of just 1,500 rpm. Maxxum tractors will also be equipped with an engine management system that makes up to 22hp available above rated power. For example, the Maxxum 130 CVX (which will be on show at the Ploughing) has a maximum power of 143hp, which can be boosted by the engine management system to up to 163hp for PTO and transport work.
