New Technology Offerings Enhance Operator Situational Awareness

The addition of enhanced visibility and radar object detection systems improves situation awareness and can help prevent costly damage to machines and equipment.  The addition of the advanced vision system and obstacle intelligence can help lower total cost of ownership and machine downtime.

Benefits

• The advance vision system integrates two digital cameras on the rearview mirror platforms and integrates those views, along with the rearview camera view located at the rear of the machine, into a dedicated single display within the cab.
• A dedicated, secondary display is larger and digital cameras provide a higher quality visual compared to analog cameras
• Dynamic reversal projected path lines assist the operator in visualizing the anticipated reversal path of the loader based on its articulation in order to provide better line of sight to objects or people that may be directly within that path
• Lines are overlaid within the rear camera view on the dedicated monitor.
• Distinctive audible alarm notifies the operator when an object is detected with the beep speed increasing as an object comes closer to the loader

Service improvements and capabilities to keep the loader working all day

Overview

With improvements to the electrical and hydraulic routing and features such as ground level servicing and Quad Cool, customers get an upgraded serviceability experience. 

Benefits

• Wire harness routing has been enhanced and additional retention points have been added to reduce rubbing
• Quad Cool cooling system places coolers in a unique boxed configuration that is isolated from the engine heat for increased efficiency and durability Ground-level daily service checks and fuel refill are conveniently grouped at ground level on the left side of the machine for easy access
• Factory installed auto-lube system is offered as standard equipment. Automatic greasing takes place while the machine is working which is more effective for grease distribution.
• The pump manifold has been removed from the articulation area to simplify ease of service.
• Controllers and fuse panel are all protected from the environment while also being more serviceable from inside the cab
• The hydraulic reservoir on the 744L and 824L has been relocated to the engine compartment for reduced complexity and improved hose routings.

904 P is specifically designed to perform loadout tasks in Aggregates Operations

The 904 P is John Deere’s two-pass loader solution for loading standard over the road trucks in two passes.  Built off the success of the 844L Aggregate Handler, the 904 is equipped with key features like increased horsepower, breakout force, hydraulic pressures, and bucket offerings enabling it to meet the rugged demands of the aggregates industry.

• Rugged 7.5- and 7.1-m3 (9.8 and 9.3 cu. yd.) material-handling buckets with integrated spill guards and curved side cutters are designed to heap heavier loads of processed aggregates in fewer passes and maximize load retention while still providing clear visibility to the jobsite in front of the machine.
• Tilt cylinders that are 12-percent larger deliver more breakout force than previous designs. Increased hydraulic pressure helps make repetitive bucket loading, unloading, and reloading seem like no big deal.
• Low-profile tire options improve traction, flotation, and stability over standard tires.
• Larger rear cast bumper/counterweight enables the 904 to handle an 11-percent greater payload than our earlier aggregate handlers.
• Factory-installed payload scale enables more efficient loading and tracking of material flow to maximize productivity.
• Standard factory-installed auto-lube system with empty-reservoir sensor is electrically powered and integrated with machine diagnostics.

Increased functionality with EH controls

Overview

Electrohydraulic (EH) controls allow for increased functionality to customize machine operations. Operators can adjust settings based on preference to increase productivity across a range of jobsite applications.

Benefits

• Enable soft hydraulic stops to select how abrupt the bucket or boom stops when end of travel is reached or when the lever of the joystick is released.
• Personalize both multi-function buttons, incorporated into the joysticks with up to 9 options selectable from the monitor.
  
  • From the factory multi-function 1 is set as kickdown and multi-function 2 is set as the horn

• P-tier production class loaders may be equipped with low effort, shorter throw single axis controls or joystick controls.
• Set and store up to 10 different attachment configuration settings including flow, responsiveness, and other modes through the monitor for the most frequently used attachments in your fleet.

• EH Precision Mode allows fine metering of bucket or boom movement when precision loader functions are required. This scales back on the aggressiveness of the functions during operation as well as limits flow. The feature is best utilized in any application that requires reduced hydraulic function speed such as laying pipe or installing manholes.

All day comfort in the redesigned cab

Overview

The redesigned cab in the P-tier John Deere Production Class loader lineup features improvements that provide operators with a first-class work environment. The range of creature comfort options are intended to keep operators comfortable and productive no matter what task at hand.

Benefits

• An additional 3 inches of leg room has been added over the previous K-Series loaders
• Standard premium seat with heating and ventilation and seat pan and tilt adjustment
• Cab door has increased by 79% over previous series machines at the bottom opening for easier ingress and egress
• Additional 12V power ports have been strategically placed for proper powering of devices and a USB port has been added for connecting to the radio
• Auxiliary accessory mounting points are strategically placed on the right front and rear cab posts for equipment such as a payload scale interface or CB radio
• Upgraded HVAC system, including automatic temperature control, improves cooling capacity, adds additional precision control, and increases reliability and durability. 
  • The AC unit has been relocated to the right side of the cab for easier access and service
  • The fresh air filter exchange is made through the top of the unit located outside the cab.  This allows the dirty filter to be replaced completely outside of the operator compartment.
  • The brushless motor provides infinite fan speeds, quieter operation, and increased airflow.
  • A standard blower vent located behind the seat defrosts the rear window is adjustable to control the direction of air flow.

• The sealed switch module has been updated and relocated on L-series and P-tier loaders. The new location brings the switches to the operator’s line of sight during operation for quick reference and ese of selection. There are also multiple updated and new functions included.

  • Selecting the About button on the main menu of the monitor, then going down to SSM feature button the next screen takes you to a menu where you can view each button on the SSM and learn more about each feature.

Increased power and lower fuel consumption

P-tier production class loaders pack more power and burn less fuel than previous series machines helping increase productivity to keep up with all the demands of the sites they work on.

Confidently hit loading targets with SmartWeigh™, John Deere’s unique payload weighing system

Overview

SmartWeigh™ is a John Deere designed and supported payload weighing solution that delivers accurate measurements, dynamic weighing capabilities, and is easy to calibrate.  For those not sold on whether or not a payload weighing solutions is a fit for your application, John Deere offers a low cost 250-hour trial period that provides you full SmartWeigh™ capabilities to help enable you to make the decision.

Benefits

• Leading Accuracy: SmartWeigh™ provides operators with increased accuracy (+/- 1.5 percent) because of John Deere’s expertise knowledge of our loader’s kinematic properties and exact dimensions and specifications.  This ensures near exact target weights are hit and efficiently loaded into feed mixers, trucks, hoppers, or processing plants.  This also helps prevent the loader from having to go back to the pile to get more material or to dump excess material.
• Seamless Calibration: Unlike other payload weighing systems, SmartWeigh™ does not need to be calibrated with a known weight and is designed to be easy to complete without the help of a dealer. By going through an easy-to-follow calibration process in the machine monitor, the system will be ready to accurately weigh material.
• Dynamic Weighing: There’s no need to constantly lower and reraise the boom of the loader to determine the weight after tipping off material. Bucket capture height can be set anywhere from 15-90 percent of boom height and can be captured at any boom speed.  The SmartWeigh™ system can automatically determine the new weight after tip offs, reducing the time it takes to load the exact amount of material.
• John Deere Designed and Supported: SmartWeigh™ is a John Deere designed and supported solution meaning if issues arise, the only call you need to make is to your John Deere dealer.
• JDLink™ Integrated: Integration of payload weighing data into JDLink™ means that you can access the data from nearly anywhere, not just within the cab of the machine.
• Factory and Field Kit Options: A range of options are available to equip John Deere utility loaders with SmartWeigh™ including fully integrating from the factory or adding through field kits.  The 250-hour trial period enables you to utilize SmartWeigh™ for 250 machine hours and decide if you would like to easily add on the feature for the life of the machine after the trial period expires.
