Stalkbuster eliminates maize pest

Corn Borer has become a serious issue in maize growing regions.

According to the Food and Agriculture Organization of the United Nations, the pest causes yield losses up to 50%. The FAO also estimate that the borer’s caterpillar destroys 4% of corn harvests globally.

Borer caterpillars damage corn by chewing tunnels through the corn plant, thereby restricting its water and nutrient supply and making the stems easy to snap. This means the plant is more susceptible to diseases – such as the common corn smut and fusarium infections that can also go on to affect subsequent crops.

To help alleviate the problem, New Holland Agriculture is introducing a new 8-row maize header fitted with the Stalkbuster System. This system controls the borer problem without needing to use pesticides or biological plant protection agents.

Working with header supplier Kemper, the system is integrated into the base frame of the rotary 8-row corn header and breaks up the stubble before it can be flattened by the harvester’s wheels.

Consisting of a swinging gearbox with an integrated ratchet clutch that swings the specially shaped Buster flail, each row of stubble is broken up individually. The special swinging gearbox ensures optimum ground adjustment for every single row, while a pneumatic pressure system provides for additional soft tracking of ground contours.

If the self-propelled forage harvester needs to reverse, the Stalkbuster units are automatically lifted when the drive lever is actioned, preventing any damage.

The action of the units sees stubble smashed into small pieces down to the ground level, destroying the overwintering habitat for the corn borer. This also reduces the fusarium risk and lowers lessens any bulky residues for post-harvest cultivation operations.

With a power requirement said to be only 4hp per row, the system uses much less power than traditional post-harvest mulching. It also has the additional benefit that stalks are “chopped’ before they are flattened by the harvester wheels or those of a tractor powering a conventional mulcher, making the process cost effective.

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.
