Please understand, I am in no way implying our tractors and excavators are

about it, what is Artificial Intelligence really? According to some, it is simply a computer system able to do things that would normally require human intelligence to accomplish. The Turing Test, created by Alan Turing in 1950 while working at the

Computer Laboratory at Manchester University, sought to define these parameters.

In-house development of a hydraulicallypowered shaker head enables one OEM to ease tree crop harvesting for farmers.

The COE M7 mono boom shaker is one of several pieces of specialty

agricultural equipment designed by Coe Orchard Equipment Inc. (COE).

Developed to ease nut harvesting, the mono boom shakes both tree

trunks and limbs to remove walnuts, pecans and almonds from the trees on which they grow. It is capable of ALL IMAGES COURTESY OF COE ORCHARD EQUIPMENT INC.

reaching the highest points on larger trees to ensure the most efficient nut removal.

The heart of the mono boom is

the COE-designed TH7X shaker head.

Once hydraulically clamped onto a tree, a hydraulic motor drives the

shaker head’s internal components

to create a shake pattern that will remove nuts from the tree. This shake pattern is adjustable in order to

adapt to different harvest conditions.

According to Dave Short, respon-

sible for working with COE’s dealer

COE builds the shaker head and its says the company tries to build as much in-house as it can to better

control quality. Hydraulic cylinders, hub mounts and doors are among

the components built by COE, which includes forming them from sheet metal.

In addition, the company builds

the chassis of the mono boom itself.

COE developed the chassis in such a way that it acts as a counterweight

to the very heavy shaker head. “The chassis is designed to balance the

COE’s dual cool system. It is a standalone cooling system designed to

cool the super-heated charge air de-

livered by the engine’s turbocharger.

Cooling the charge air provides

better performance and a reduction in harmful exhaust emissions. The

system in turn enables the engine

fan to efficiently cool the radiator, oil cooler and air conditioning con-

denser. “It’s a matter of efficiency

and performance,” says Short. “We

want to be able to cool those three

components yet still achieve cooling for our engine charge air.” The dual

cool system features its own fan and radiator to keep it running cool too.

A new method for testing emissions output of off-highway equipment in the field may provide manufacturers with a better means of optimizing their designs.

In-field testing, consisting of the tractors doing cultivation work, enabled different parameters such as soil conditions and depths of cultivation to be taken into account which can affect load on the engine, and thus emissions.

equipment, the only change neces-

Stage V makes infield testing a reality In September 2014, the European Commission announced its proposed Stage V emissions standards for non-road mobile machinery (NRMM) which for the first time will require in-use vehicle testing.

“They’re aware that up to date there have been companies who are able to make their engines suit the test cycles they’re being tested to, but still they think there needs to be some sort of actual in-use, real-life vehicle testing,” explains Robert Fillingham, Ph.D. student at Harper Adams University.

The proposal calls for monitoring of in-use gaseous and particulate emissions by testing engines installed in machinery operated over its normal duty cycles. Pilot programs to determine appropriate testing procedures will be conducted by the European Commission. It anticipates detailed provisions and technical specifications to be adopted

by December 2016.

Under Stage V, more engine power ranges will be regulated including those below 19 kW and above 560 kW. Also for the first time particle number (PN) emissions will be regulated in order to account for ultrafine particles. Currently a PN limit of 1 x 10 12 kWh-1 has been proposed for engines ranging between 19 and 560 kW, which will require all NRMM engines be equipped with a diesel particulate filter (DPF).

Electric drives are not a new technology, but the adaptation for off-road vehicle applications is in its infancy as battery technology and rugged but cost efficient components continue to develop.

electric systems and battery technology continue to develop, the ability

to adequately replace hydraulics with

electronics is becoming more likely—

if not for the benefit of safety, then for the environmental benefits of higher efficiencies and thus reduced fuel

consumption and lower emissions.

While the advent of high volume

systems. “We see a continuously in-

creasing demand for electrical power from various implements,” says Dr.

Benno Pichlmaier, Head of Research & Advanced Engineering, Fendt, an AGCO brand. “Also, the demand for

electric energy of the tractor systems itself has grown substantially.”

The AEF (Agricultural Industry

Electronics Foundation) has an entire project team dedicated to develop-

ing a proposal for a standard tractor

power to attached machines and

AEF’s website, the idea behind the

project team is that the electric drive systems on all standard attached

machines should be compatible with every electrified tractor, and the only limitation should be the electric out-

put power of the tractor. Locally controlled, decentralized electric motors can overcome the restrictions of

mechanical and hydraulic solutions

and meet the requirements of a new generation of attached machines, and should also provide considerable benefits at the same time.

With the high-voltage interfaces at the back and front of Fendt’s X Concept tractor, 130 kW can be provided to drive electrically powered implements.

The tractor and implement communicate via the standardized ISOBUS. Electrical power of up to 130 kW is transmitted to the implements in the form of a 700V DC supply via the POWERBUS, which provides power to internal tractor consumers such as the electrical fan drive or the coolant pumps.

Pichlmaier notes several other

reasons for pursuing electric tractor

technology in the agricultural industry—as Fendt has with its X Concept tractor, presented at Agritechnica

2013—including sustainability goals,

agronomic process efficiency, technical efficiency, higher safety, comfort and reliability. “Electrification is an

enabler for more sustainability. Elec-

tric farm equipment can be perfectly integrated to support and stabilize renewable energy grids like solar

power or biogas,” says Pichlmaier.

In terms of dynamics, controllability

and flexibility electric drives are superior to any other solution, states Breu.

A Koehring 205 Skooper used cables for hoisting and hydraulics for bucket reach, breakout and dump.

KOEHRING SPEC SHEET K601-1, SEPT. 1959, HCEA ARCHIVES

The evolution of the Skooper

by Thomas Berry, Archivist, Historical Construction Equipment Assn. (HCEA)

The Koehring Skooper is considered the first heavy-duty hydraulic front shovel machine in the American market, but where did the idea come from?

The Skooper line originated in

at two yards capacity, it was sub-

stantially larger than other such

machines of the time, and its 1957

introduction made it the first American-made hydraulic shovel.

That said, it wasn’t a true hydrau-

lic machine, as only the crowd and dump were hydraulically powered

with all other functions operated by cable. The hydraulic crowd gave it

the capability to dig on a level plane from a fixed position up to 7 feet across a 7-foot range.

The combination of horizontal

resulted in several advantages over

digging plane and breakout of a crawland dump from a fixed position rather than continually cycling from cut to

dump reduced fuel costs and eliminated wear or transmission and tracks or tires while reducing operator fatigue.

be converted to a cable-operated

shovel, crane, clamshell, backhoe or – ironically – conventional shovel.
