Stronger chassis highlight of new Claas Rollant round baler, Chris McCullough reports
Astronger chassis and new rollers are key features on the latest Rollant 540 fixed chamber round baler from Claas. Available with the choice of net or film wrapping, the new Rollant 540 will produce bales with a diameter of 1.25m and widths of 1.22m. The 540’s baling chamber is formed by 16 rollers, made from 4mm thick steel plate.
The serrated profile of the rollers maintains optimum bale rotation even under moist conditions. Bearing and power transmission functions are performed via specially hardened 50mm-diameter lateral-axle stubs on the input drive side. They are flange-mounted on the roller body, and can be individually replaced if necessary.
The tailgate closing rams are arranged horizontally at the sides, resulting in high baling pressures. This new design also reduces the pressure exerted on the tailgate and ram bearing structures.
For maximum bale density, forces of up to 180-bar can be applied to the rams, while for further increase density, the Rollant 540 can also be supplied with the MPS II system as an option. With MPS, a segment bearing three of the baling rollers pivots into the chamber for additional bale compression, early bale rotation, and a “perfectly” uniform bale shape.
The baling rollers are driven solely from the left-hand side of the machine. Each roller has direct drive, resulting in uniform force distribution to the rollers with a lower power requirement.
The rotor and main drive have 1.25-inch drive chains, and the tailgate rollers are driven with a one-inch chain. These chains are lubricated via an eccentric pump, with oil supply from a 6.3-litre storage tank. All the lubricating nipples of the MPS and tailgate are combined on the right-hand side. A central lubrication option is also available and lubrication interval can be set on the control terminal.
A 2.10m-wide controlled pick-up retrieves the crop reliably and efficiently, and a double flattening roller is available as optional equipment. This improves crop flow, especially for particularly large and small swathes, and promotes uniform bale formation. Meanwhile, two lateral feed augers provide a reliable supply to the rotor.
The optional chopping mechanism has 15 knives, with a theoretical cut length of 70mm. The knives can be swung in from the cab, and have individual protection against damage from foreign objects.
For blockages, the cutting chamber can be lowered with a command from the control terminal. This provides an extremely user-friendly system for the driver, and minimises downtime. There is also a lower power requirement for restarting the mechanism afterwards.
Customers of the new Rollant 540 have the choice of net or film wrap. Changing the wrapping mode is a tool-free operation, performed simply by adjusting the side screws of the guide roller.
A ramp on the right side of the machine simplifies the task of loading the wrapping system. With the Comfort system as optional equipment, wrapping system settings can be carried out directly from the cab.
