Case IH used Sima 2013 to announce its new Maxxum CVX tractors that will offer between 110-140hp. The three new models feature a continuously variable transmission and will join the range of Maxxum EP (Efficient Power) tractors – launched at Agritechnica 2011 – in 2014.
The Maxxum 110 CVX EP, Maxxum 120 CVX EP and Maxxum 130 CVX EP are true workhorses for all kinds of farm operations, equipped with powerful engines and comfortable cabs.
”These new models follow the trend towards continuously variable transmissions and extend our portfolio in the medium power class with four-cylinder engines,” Case IH’s Maxxum range product manager Vincent Hazenberg said.
Maxxum CVX EP models feature Case IH’s proven CVX transmissions with double-clutch technology.
The transmission, first seen on the brand’s Puma tractors, operates continuously variable between 0-50 km/hr and has two mechanical gears for an excellent overall efficiency.
The hydraulic power is evenly available over the full speed range of the tractor with less than 25 per centhydraulic power share. The 50km/hr Eco speed is reached at a low engine speed of 1,750rpm, with40km/hr available at 1,600rpm.
The transmission is fitted with helical gears for smooth running at all speeds. Two forward gears, reverse and the shuttle gear are changed automatically using the double-clutch.
With their own clutch, changeover between odd and even gears happens seamless and smoothly, and as result levels of comfort and efficiency are reached that are hardly achievable with any other approach. The clutches will only engage when both are rotating at the same speed – ideal for achieving an extended service life. Double-clutch technology ensures that losses are minimised which ensures maximum efficiency.
Maxxum CVX EP tractors are also equipped with APM (Automatic Productivity Management), a feature that has already proven very effective in larger Case IH tractors. APM automatically reduces engine speed when less power is needed. Maxxum EP tractors also have an active stop control system. This holds the tractor safely in the stop position even on hills, whether or not a load is attached, without having to operate the clutch. Active stop control also makes it easier to drive on slippery surfaces and ensures less wear on brakes and clutch plates. This allows for an increased level of safety since there is no need to activate the parking brake.
The new Maxxum CVX EP tractors are powered by rigid turbocharged engines with intercoolers. The four-cylinder engines have a capacity of 4.5 litres. All models have electronic common rail injection. The engines deliver a power boost with a 10 per cent power increase at the reduced engine speed of 1,900rpm. This results in a markedly lower fuel consumption. In addition, they are also fitted with a precision fuel injection system.
The new Maxxum CVX EP series is equipped with the EP system and includes an SCR system built by Case IH. They have been optimised for efficiency, and maximum torque is reached at an engine speed of just 1,500rpm. Furthermore, the Maxxum tractors feature an engine power management system that delivers up to 22hp more than the rated engine power.
The Maxxum 130 CVX EP, for example, has a rated power output of 143hp that can be increased to 163hp for transport and PTO applications.
The idle speed management system is another innovative development and is a new software function that has been developed that further reduces fuel consumption and operating costs. The engine automatically reduces idle speed from 850rpm to 650rpm. This reduction takes effect 30 seconds after the driver has left the cab when no electronic remotes nor the hitch are being used.
The new Maxxum CVX EP range is equipped with a surround cab, offering one of the most comfortable tractor workplaces on the market. The cab is the largest in its class, with an exceptional view through windows which total 5.78 square metres. The four-pillar design and the integrated roof window provide unobstructed visibility, giving the driver a 105–degree forward view, ideal for front–loader work. At just 71dBa, the Maxxum CVX EP cab is also the quietest on the market.
The new Maxxum CVX EP models benefit from the same proven control concept as larger Case IH tractors right up to 600 hp. The ergonomic design of the controls ensures extremely efficient operation: all key switches and buttons are integrated, like the Multicontroller, into the right-hand console. The same console can also house the AFS Pro 300 or the AFS Pro 700 touch-screen monitor, making the Maxxum CVX EP ideal for precision farming applications.
As a true all-rounder, the Maxxum is equipped with a very flexible hydraulic system. An axial piston pump delivers high flow rates of up to 125 lit/min on-demand, including pressure and flow regulation. The rear hitch is capable of lifting 7,867kg, while the optional front hitch lifts 3,100kg. Up to seven electro-hydraulic remote valves allow a wide range of hydraulic functions to be controlled Up to four remote hydraulic connections in the back and three mid-mount connections can be specified.
A new front hitch management system makes it much easier to operate front-mounted implements. Two height settings can be programmed, and the automatic float setting allows the front hitch to switch automatically to float mode as soon as the working position is reached. This is ideal when working with front mowers, for example.
The new Maxxum CVX EP series is built at the St Valentin plant in Austria and will be available in January 2014.
