Bale feeder built for a hard life

McIntosh of Palmerston North has a reputation for building feed equipment with a robust construction, clever engineering and a long working life.

The company’s Double Bale Feeder builds on this reputation and offers the ability to deal with round or square bales.

From a practical point of view, one of the worst traits of a “normal” bale feeder is the tendency to run over the feed it has just delivered. In the case of the McIntosh Double Bale feeder, a 315mm overhang from the tyre edge to the outside of the bale feeder frame means that delivered feed is never “run over” and pushed into the ground and wasted. This represents a huge cost saving, particularly when operating in wet conditions.

The construction layout sees two box sections running through the bale cradle to increase overall strength, while also lowering the overall loading height and centre of gravity, promoting stability and safe use on hillsides or sloping ground.  A choice of wheel settings enhances safe operation on difficult terrain, and buyers have the option of fitting larger tyres. Standard equipment features 11.5 x 15.3 tyres, a detail that helps to reduce rolling resistance, making towing easier in poor conditions, with the option of increasing the footprint by fitting 400/60x15.5 tyres for poor conditions.

At the rear, an over-dimensioned lifting arm can deal with the heaviest bales, while also offering the ability to carry a second bale to the feeding area. The design features twin lift rams which gently lower the bale onto the unrolling cradle and help prevent damage to the feeder bars.

The unrolling cradle uses a zinc-plated, 12,000lb-rated chain, with slow running shafts utilising bronze bushes for resistance to silage juice and a greater service life.

Unloading slats are manufactured from 8mm steel with integral teeth to promote bale rotation by increasing the contact area, while in the cradle, aggression pins restrict bale movement to encourage the teeth to pull the bale apart.

The large hydraulic motor comes with a 1 ¼ shaft and heavy-duty key. From a practical point of view the machine includes a rubbish bin, and a chequer-plated platform on the drawbar a-frame to allow the user to safely remove the film and net wrap.

Practical options include a third central tine for the rear lifting forks, said to be useful for dealing with soft or mis-shaped bales, while for those handling square bales, lateral extensions, each carrying an extra tine, ensure positive lifting onto the cradle. If handling chopped bales, users can specify front and rear infill panels to stop material being lost before it heads up the discharge conveyor.

In addition to the lateral extensions, those feeding squares might also option the machine with siderails for the bale cradle.

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.
