RELIABLE PRODUCTIVE

+

ROCK STAR.

CRUSH IT.

With larger material-handling buckets and beefed-up performance specs, our new 844K-III

Loader delivers serious productivity. And it’s built rock solid to take on the toughest aggregate

and material-moving applications. Armed with insights from our Customer Advocate Group,

we designed this productive machine to be even more rugged and reliable. We equipped it with

improved hydraulic plumbing and advanced onboard diagnostics with push-button customization

of machine operation and response. These are just a few of the ways our latest model helps you

increase productivity and uptime, while lowering daily operating costs. Read on to learn how the

844K-III will benefit your operation.

TOP OF THE HEAP.

BUILT FOR FASTER CYCLES

AND LONG-TERM DURABILITY

The 844K-III Loader heaps heavier and hauls more. And with redesigned hydraulic

plumbing and beefier components, it’s more reliable, too.

Better transmission shift logic and adaptive clutch cutoff

Improved transmission shift logic and new adaptive clutch cutoff help increase productivity and deliver smooth gear changes in a variety of jobsite conditions.

Steel tubing replaces hosing

Over three dozen steel tubes replace 81 ft. of hoses, reducing friction and the number of troublesome connection points.

Low-profile tire option

Want to increase the traction, flotation, and stability of your 844K-III? Spec the low-profile tire option.

Strong engine power

Productively capable engine horse- power and peak torque in the proven John Deere PowerTech™ diesel tackle tough stockpiling and digging tasks. Also ably meets EPA Tier 3/EU Stage IIIA emissions.

REPLACE 81 FT. OF HOSING

OVER 3 DOZEN STEEL TUBES

HARD WORK MADE EASY.TAKE A LOAD OFF

Improved balance and stability

Low center of gravity and optimized fore-and-aft balance deliver solid stability and full-turn tipping-load capacities.

Fuel-sipping diesel

Fluid-efficient John Deere PowerTech engine provides generous displace-ment, power, and lugging ability.

Coated against corrosion

Cab surfaces have been treated with extra corrosion resistance, improving durability for the long haul.

Quick ground speed and boom lift

Reliable powertrain and hydraulic performance helps maintain quick ground speed and boom lift, even on steep ramps, for faster cycles.

Low-effort joystick control

Standard joystick steering boosts fatigue-beating comfort and is ideal for V-pattern truck loading. It adapts to ground speed to deliver smooth, low-effort control, even during load-and-carry operations.

Faster cycles and better fuel economy

Standard five-speed transmission with torque-converter lockup in gears 2–5 increases acceleration, speeds cycles, and optimizes power and fuel efficiency during transport, roading, and ramp climbing.

Multiple axle configurations

Axle choices include manually actuated front differential lock with conventional rear axle, front and rear differential locks, or conventional rear and front axles. Automatic locking is optional for axles with locking differentials.

8

Keep your cool

Quad-Cool™ design places coolers in a unique boxed configuration that’s isolated from engine heat, for increased efficiency and durability. Standard hydraulic reversing fan auto- matically reverses at predetermined intervals, or can be programmed through the monitor, to eject debris from the cooler cores.

Easy diagnostics

Color-coded fluid-sample and diagnostic test ports speed preventative maintenance and troubleshooting. If something goes wrong, the easy-to-navigate LCD monitor displays diagnostic messages and offers possible solutions to get you back up and running quickly.

Shorter hoses with better routing

Bulkhead fittings eliminate long hoses, simplifying replacement and component exchange. Hydraulic tank on the 844K-III is positioned behind the cab for easy access, and hoses have been routed away from other vital operating components, for longer wear life.

Reduced tire wear and cost

Deere-exclusive integrated tire monitoring reports pressures and temperatures on the monitor and remotely through JDLink™ Ultimate, to help reduce tire wear and replacement cost.

Loader operating information is based on machine with identified linkage and standard equipment, PowerTech Plus 6135 (EPA Tier 3/EU Stage IIIA) engine, ROPS cab, rear cast bumper coun-

terweight, transmission side-frame guards, bottom guards, standard tires, full fuel tank, and 79-kg (175 lb.) operator. This information is affected by changes in tires, ballast, and different

attachments.

*Rated operating capacity based on Deere attachments only.

Adjustments to Operating Weights and Tipping Loads with BucketsAdjustments to operating weights, tipping loads, and tires are based on Z-Bar machine with pin-on 5.5-m3 (7.25 cu. yd.) general-purpose bucket with bolt-on cutting edge, ROPS cab, rear

cast bumper/counterweight, transmission side-frame guards, bottom guards, standard tires, full fuel tank, and 79-kg (175 lb.) operator*
