Claas Balers Turn 30
Claas built its first variable chamber round baler - the Variant 100 - in 1996, so 2026 marks 30 years and the fifth generation of the Variant name, recently complemented by the new Cerex Series introduced in 2025.
Aimed at commercial hay producers to meet the challenges of greater field performance, unmatched bale consistency and industry- leading uptime, the SB.1436DB “addresses the increasing pressure from labour shortages, tight harvest windows and demanding quality standards,” said Dane Mosel, marketing manager, Hesston by Massey Ferguson.
By producing two rows of bales per pass, the machine effectively doubles capacity, reducing the need for additional labour, equipment and fuel. The 105-inch pickup width, said to be the widest width in the high-capacity small square baler industry, improves field efficiency and reduces labour needs by optimising movement of hay into the baler.
SimplEbale offers an advanced electronic monitoring and control system that automates critical baling processes, helping to ensure consistent bale density, weight and dimensions. From the cab, operators can monitor flake thickness, flake count, bale length and bale weight in real time, ensuring maximum throughput the working day.
“This can cost over eight hours of additional baling time,” said Mosel. “SimplEbale eliminates this issue by automating bale production, helping operators achieve better results.”
Operating at 90 strokes per minute with a 21.9-inch stroke length, the MF SB.1436DB requires a tractor of 120hp to help it deliver a target bale weight of 40 pounds, made up of 12 flakes and secured by two twines. The company suggests an operator can produce 71 bales or 1.43 tons per hour by just averaging two extra flakes per bale.
In operation, hay is conveyed into a single 14-by-36-inch chamber and separated via a splitting knife to create individual 14-by-18-inch bales. From there, it passes through a common density system that ensures consistent compression, with independent knotter trips on either side of the baling chamber for precise bale lengths.
Completed bales are dropped through the bale chute into independent rows, simplifying handling and transport. The independent knotter trips improve bale length consistency at preset lengths between 24 and 52 inches, allowing for a more standard product, despite windrow or operator inconsistency.
Twine capacity of up to 20 balls allows up to 8,000 bales to be produced before refilling, around double the capacity of comparable balers, while an automated knotter lubrication, reducing the need for frequent manual maintenance.
