Case IH LB436 HD large square baler.

Farmers and contractors seeking to pack more material into every bale are offered a new way to to reduce handling requirements and transport costs.

A new model added to the top of the Case IH LB 4 XL (LB436 HD) large square baler range for 2020 embodies new designs and components and can make bales up to 22% more dense than the LB434 XL model (which produces the same 120 x 90cm bale size and remains in the range).

Uniquely, the LB436 HD includes a new main gearbox and mid-mounted gearbox with gearshift overload protection for high power transfer and driveline safety.

In addition, an innovative new twine knotter system, called TwinePro, is designed to boost productivity while eliminating field litter and bale contamination.

The LB436 HD is also fully ISOBUS Class 3 compatible.

The 2.35m pick-up has a mechanically driven top-assist roller and roller wind guard to ensure effective crop feed, and five tine bars are fitted with 5.5mm diameter items for a clean pick up at high speeds.

The LB436 HD is equipped as standard with Case IH’s Rotor Cutter chopping system: 29 knives with an adjustable knife selector allowing 7, 8, 14, 15 or 29 of the individually protected knives to be engaged.

In operation, when the PTO is engaged, the baler flywheel will speed up in two stages, from 0-684rpm and then from 684-1244rpm to its maximum 1445rpm at 1000 RPM PTO speed.

The LB436 HD has an adjustable precompression chamber with shear bolt protection and a plunger with a maximum speed of 48 strokes/min. The plunger stroke is longer and its force is increased by 150% over that of the LB434 XL model. The compression channel is longer and while existing models have two cylinders for compression the LB436 HD uses seven.

The new TwinePro knotter system offers a significant increase in tensile strength and increased daily productivity from greater baling efficiency with reduced twine breakage risk.

The system is combined with redesigned needles and a new needle yoke reclaim system and electric knotter fans keep the units clean.

Once the first standard knot is tied, a second knot is created for additional bale security, offering up to 30% more strength, says twine manufacturer TAMA.

A tandem axle is standard, set up to minimise minimise scrubbing when turning by allowing the rear axle to pivot by up to 15 degrees, but this can be locked as necessary.

Case IH Wins EIMA Award for Optum Suspension System

With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.

The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.

In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.

Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.

Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”

Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.
