New Cat D Series Agricultural Telehandlers

The new D Series agricultural telehandlers offer a wide choice of powertrains, a load-sensing hydraulic system, a comfortable operator environment and exceptional versatility.
Three new D Series agricultural telehandlers (TH357D, TH408D and TH3510D) have been designed to handle the most demanding tasks on farms.

They offer lifting capacities ranging from 3 500 to 4 000 kg (7 716 to 8 818 pounds) for lift heights from 7 000 to 9 800 mm (23,0 to 32,1 feet).

A wide choice of engines and power ratings delivers outstanding performance and fuel efficiency in any type of application.

These new models have been designed to deliver fast hydraulic response, increased operating comfort, and ease of maintenance and operation.

Whether stacking bales, cleaning barns, loading trailers or moving grain, the new models can handle these tasks with a wide range of work tools such as bale grabs, buckets, pallet forks, a material handling arm, or a sweeper.

The standard manual coupler or the available hydraulic coupler, both featuring the Cat® IT-type interface, make tool changes easier, while the powerful Z-bar linkage ensures excellent breakout force and optimal bucket working performance.

Hinges are located at the rear to increase the machine's versatility by adding lifting capabilities.

Powertrain and hydraulic system
These three new models are equipped as standard with the Cat C3.4B 83 kW engine (111 HP); for applications requiring more power, the Cat C4.4 ACERT™ engine, with a rated power of 93 kW (124 HP), is available as an option.

The TH408D and TH3510D models can also be fitted with the C4.4 ACERT engine, with a rated power of 106 kW (142 HP).

A heavy-duty transmission with 6 forward and 3 reverse speeds (6F/3R), available on all models, ensures consistent gear ratios across various applications.

The four-wheel-drive system uses heavy-duty axles with planetary reduction hubs, a limited-slip front differential and a braking system on both axles to enhance safety.

In addition, a wide choice of tires makes it possible to adapt the machine to the chosen application in order to optimize performance.

A closed-center load-sensing hydraulic system, featuring an efficient variable-displacement axial piston pump and load dividers, provides fast hydraulic response and adjusts flow and pressure to the task to save fuel.

A standard auxiliary hydraulic circuit is connected to the boom head for powered work tools.

A second auxiliary circuit at the front is available, as well as an auxiliary circuit for the rear of the machine.

For greater operator comfort, the hydraulic system is equipped with a cylinder damper to cushion the impact of the telescopic boom sections.

The adaptive longitudinal stability indicator simplifies hydraulic system operation through a mode that allows normal operation, without limitations, when the machine is moving and the parking brake is released.

This smart feature removes the need for the operator to press an override switch or leave the equipment to reset the hydraulic functions.

Operator station
The operator station, with a reduced sound level of 75 dB(A), features a multifunction joystick with transmission controls (column-mounted transmission controls can be specified) and auxiliary hydraulic function controls.

The dashboard features an ergonomic control layout and a new LED display showing fuel and speed data.

The fork and bucket mode switch changes the responsiveness of the hydraulic systems to favor power or precision. The heating system keeps the cab at a comfortable temperature in cold weather; air conditioning is available as an option.

The low boom pivot points, raised cab and curved hood profile provide good visibility, and a rear-view camera and perimeter sensors greatly increase operator awareness on the job site.

Six standard work lights provide a large illuminated area for working in low light.

The advanced display system provides easy access to machine information and settings, including load charts, maintenance schedules and rear-view camera images.

The display allows you to set hydraulic response levels, drive modes and reversing fan intervals.

When different work tools are selected, the display shows the appropriate load charts, and machine users can also program user codes via the display as a theft deterrent.

A ride control system also dampens boom movement when traveling over rough terrain at speeds above 5 km/h (3 mph).

In addition, an intelligent boom suspension system allows the boom to automatically follow the contour of the ground, preventing work tools from scraping the surface.

Both features promote smooth driving and improve operator comfort, as do the air conditioning system and the heated air-suspension seats.

Serviceability/Technology
Diagnostic checks can be performed from the display screen to simplify maintenance.

Daily service points are accessible from the ground, and the longitudinal engine positioning and wide hood provide easy access to the engine, cooling package and hydraulic components.

A cooling package handles high ambient temperatures, and the variable-speed hydraulic reversing fan protects the vertical cooling cores from debris.

With Product Link™, an integral part of LINK technologies, owners can connect wirelessly to their equipment and access essential machine data such as location, service hours, fuel consumption, idle time, events that have occurred, and diagnostic codes, in order to generate analyses and reports via the VisionLink® online user interface.

The information provided by LINK technologies helps make fact-based decisions to optimize productivity and reduce operating costs.
