Description
KOMATSU — D61EX-24 — MID-SIZE DOZERVersatile to accomplish any task, the D61EX-24 brings excellent visibility to all your projects. The second-generation mid-size dozer comes with a new H mode that helps operators maintain ground speed while operating under heavy loads.FEATURESPARALLEL LINK UNDERCARRIAGE SYSTEM (PLUS)Designed to wear evenly so the machine provides close to 100% usage of undercarriage components, Komatsu PLUS undercarriage lowers undercarriage maintenance costs by up to 40% over a conventional undercarriage. Strengthened rollers and links increase wear life up to two times.PAT DOZER WITH ADJUSTABLE PITCHExpand your productivity and gain more versatility in a variety of applications with a power angle tilt (PAT) dozer blade with adjustable blade pitch system.EXCEPTIONAL BLADE VISIBILITYAn innovative super-slant nose design provides excellent blade visibility for improved machine control and increased efficiency and productivity.HST WITH ELECTRONIC CONTROLFully electronic control provides complete automatic shifting and enables smooth control. Equipped with Komatsu-designed HST, this machine allows for Quick-Shift or variable speed selection.EASY-ACCESS MAINTENANCE FEATURESA swing-up fan with a gas strut-assisted lift system provides easy access to the radiator, oil cooler and charge air cooler. The hydraulic fan has a reversing fan for cleaning any objects that are restricting air flow.PALM COMMAND CONTROL SYSTEM LEVERDesigned for your operator’s comfort and ease of use, the ergonomic, low-effort palm command control system (PCCS) joystick controls all directional movements, including machine travel speed, as well as counter-rotation.STANDARD EQUIPMENT• Accumulator for Electric Proportional Control (EPC)• Air cleaner, dry, double element type with caution lamp on monitor• Air conditioner (A/C)• Air inlet• Alternator, 24 V/90 A• Back-up alarm• Batteries, large capacity 24 V/200 Ah• Cab accessories— 12 V × 2 power supply— Cup holder— Rear view mirror— Rear view monitor system (1 camera)— Bluetooth/USB compatible radio with remote AUX plug (3.5 mm)• Crankcase guard and underguard• Decelerator/brake pedal (Single pedal)• Electronically controlled Hydrostatic Transmission (HST) with quick-shift and variable speed settings• Electronic monitor panel with on-board diagnostics• Engine hood and side panels• Engine, KOMATSU SAA6D107E-3, gross output of 170 HP, direct injection, water-cooled turbocharged, air-to-air aftercooler, cooled EGR, EPA Tier 4 Final and EU Stage 4 emissions certified• Engine secondary shutdown switch• Equalizer bar grease port• Fan, hydraulic driven, electronic control• Filler cap locks and cover locks• Fluid sampling ports• Foot rest, high mounted• Fuel pre-filter (10 micron) and fuel filter (2 micron)• Grease gun holder• High altitude arrangement (No fuel adjustment up to 2300 m)• Horn• Hydraulics for PAT dozer• Hydraulics for rear equipment• Intake pipe with precleaner• Komatsu Diesel Particulate Filter (KDPF)• KOMTRAX Level 5.0• Large high-resolution LCD color monitor• LED worklights• Lunch box holder• Marks and plates, English• Operator Identification System• Palm Command Control System (PCCS) with electronic control for travel control• Palm Command Control System (PCCS) with EPC for blade control• Power turn with counter rotation• Pullhook, front• Radiator guard grid• Radiator reserve tank• Real-time DEF monitoring• Rear-hinged radiator guard• Reverse travel speed presets• ROPS cabMeets ISO 3471, SAE J/ISO 3471 ROPS standards, and ISO 3449 FOPS standard.• Seat belt, 3" retractable• Seat belt indicator• Seat, air suspension, fabric, heated, low back, headrest• Shovel holder• Starting motor, 24 V/5.5 kW• Selective Catalytic Reduction (SCR)• Self adjusting roller• Side by side rear mounted cooling package• Sprockets, bolt-on• Sprocket inner guard• Tie off points standard (ISO 14567)• Track roller guards, end section• Track shoe assembly (PLUS)—Sealed and lubricatedD61EX-24: 24" single grouser shoeD61PX-24: 34" single grouser shoe• Triple labyrinth final drive shield design• Underguards, heavy duty• Engine• Transmission• Variable Geometry Turbocharger (VGT)• Water separatorOPTIONAL EQUIPMENT• Dozer assembly• Drawbar, long type• Track roller guard, full lengthMulti-shank ripper:• Weight: 3,874 lb• Beam length: 7'1"• Maximum lift above ground: 1'8"• Maximum digging depth: 2'2"Specifications are subject to change without prior notice.
