D1 Mulcher
THE RUNDOWN
IMPROVED VISIBILITY
- A lower sloping hood line provides improved peripheral vision to the mulching head, allowing the operator to better assess the jobsite.
SEAT MOUNTED CONTROLS
- Mounted on the air suspension seats, these controls isolate the machine vibration from the operator, reducing operator fatigue.
INTUITIVE OPERATOR INTERFACE
- Primary display is a 254 mm (10") touchscreen color monitor with back up camera.
PRESSURIZED CAB
- Heated and air conditioned cab offers comfortable working environment resulting in less operator fatigue and improved productivity.
HINGED RADIATOR GRILL
- Allows for easy clean out of radiator without the need for tools.
TRACTOR PLATFORM
- Balanced and rugged for operating in rough terrain and soft underfoot conditions.
- Optional blade to provide machine application versatility.
LONG LIFE MULCHING HEAD
- New Cat® HM518 mulcher frame is designed for longer life using cladding material in high wear areas.
HYDRAULICALLY CONTROLLED
- Mulcher conveniently operates with a hydraulically operated front door and adjustable push bar.
CLOSED LOOP HYDROSTATIC CIRCUIT
- Delivers efficient, high performance power to the mulcher head, using less pump flow.
REVERSIBLE DRUM
- Easier operation and improved productivity.
DRUM SPEED BAR INDICATOR
- In-cab indicator, aids operator in managing ground speed and overall mulching productivity.
ENGINE
- Cat C3.6 diesel engine meets U.S. EPA Tier 4 Final/EU Stage V emission standards.
UNDERCARRIAGE
- Cat Sealed and Lubricated Track with 406 mm (16 in) or 635 mm (25 in) track shoes provides superior flotation and stability for wide range of operating conditions.
REVERSING FAN

SUSTAINABILITY
- The Cat® C3.6 engine meets U.S. EPA Tier 4 Final and EU Stage V, and Japan 2014 emission standards.
- Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to:
20% biodiesel FAME (fatty acid methyl ester)*
100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels
Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
* Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
- The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.8 kg (4.0 lb) of refrigerant, which has a CO2 equivalent of 2.574 metric tonnes (2.873 tons).
- With cooling fan speed at 70% of the maximum value:
Guaranteed Exterior Sound Power (2000/14/EC ISO 6395:2008) – 109 dB(A)
Dynamic Operator Sound Pressure Level (ISO 6396:2008) – 76 dB(A)
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/ windows open) for extended periods or in a noisy environment.
- Caterpillar factory fills with ethylene glycol coolants. Cat Diesel Engine Antifreeze/Coolant (DEAC) and Cat Extended Life Coolant (ELC) can be recycled. Consult your Cat dealer for more information.
- Cat Bio HYDO™ Advanced is an EU Ecolabel approved biodegradable hydraulic oil.
- Additional fluids are likely to be present, please consult the Operations and Maintenance Manual or the Application and Installation guide for complete fluid recommendations and maintenance intervals.
- The following features and technology may contribute to fuel savings and/or carbon reduction. Features may vary. Consult your Cat dealer for details.
– Eco mode minimizes fuel consumption for light applications
– Save fuel with efficiency features such as engine idle shutdown
– Extended maintenance intervals reduce fluid and filter consumption
– Cut maintenance costs with extended maintenance intervals
– Boost productivity up to 50% with Cat technologies like Cat Grade with Slope Assist and Cat Grade with 3D and Operator Assist Features Stable Blade Lift and Tilt, Blade Load Monitor, Low Slip Traction Control and AutoCarry.
– Remote Flash and Remote Troubleshoot Recyclability – 98%
