Case IH launches new Tier 3 Puma Tractor at Fieldays
Case IH is expanding its popular Puma range in New Zealand, with a new model that was released at Fieldays.
Construction sees a wave-shaped mower bed, press-formed from a single piece of material, allowing the cutting disc to be positioned further forward on the cutter-bar, ensuring the largest possible overlap between each disc for optimal cutting quality under all conditions.
Specially shaped skids and the large channel between them creates a dirt-repelling tunnel effect for clean harvesting, while the bolted design and permanent lubrication of all drive components is said to simplify maintenance and guarantee dimensional stability and durability.
The new models incorporate centre-of-gravity hitching, offering a uniform contact pressure over the entire working width, with the suspension spring forces running through the centre of gravity of the mower unit. For adaptability, the cutter-bars can be operated at angles of up to 45 degrees upwards and 20 degrees downwards.
Claas Disco Move 3600 and 3200 mowers, with operating widths of 3.4m and 3.0m respectively, feature a headstock allowing up to 600mm of travel upwards and 400mm downwards, independently from the tractor front linkage.
This is complemented by up to 30 degrees of lateral travel, improving the unit’s ability to follow contours or swing rearwards to avoid obstacles.
The headstock also includes Active Float integrated hydraulic suspension, eliminating the need for suspension spring coupling points on the tractor, with suspension pressure adjusted during operation using a single-acting hydraulic service.
The headstock, coupled directly to the tractor front linkage or using an A-frame, remains fixed during operation, with the mower raised and lowered via integrated hydraulics. A handy adjustment guide allows the front link arms to be set at the correct height from the tractor cab.
