HM912 Mulcher
HM912 Mulcher
DESCRIPTION
High-performance cutting and mulching of vegetation and overgrowth.Cat® Mulchers for Mini Excavators are designed for high-performance cutting and mulching vegetation and undergrowth from forested terrain. The hydraulic mulcher reduces saplings, shrubs and trees into mulched material, making it ideal for environmental maintenance, such as creating fire lanes. Other applications include land reclamation, foliage removal from building construction sites, and shredding pruned material and organic waste for biomass production.Bite Limiting Plates
Ribs on the rotor limit the amount of material being processed at once to reduce stalls and recovery time.
Built in Thumb Bracket
Integrated thumb bracket allows operator to pull or push the material into position to mulch or move it away from the mulching area. On equipped Cat® excavators, the machine thumb can be utilized with the integrated thumb bracket to pick up material.
Standardized Mounting Bracket
All bite-limiter mulchers will use the small-large bolt pattern that is common with hammers, vibratory plate compactors, cold planers, and grapples. Mounting brackets are available in these bolt patterns to fit the full range of compatible Cat® machines and coupler styles.
Variable Torque Hydraulic Motor
Variable displacement piston motor provides for excellent multi-function capability of machine platform. Motor displacement will change to provide high torque at low speed to power through material with reduced risk of stalling. The motor automatically switches the displacement back for high speed operation once the material is cleared.
Bolt-on Replaceable Skid Shoes
Bolt-on skid shoes are reinforced and built to last, but easily replaceable as needed. Provides differentiation longevity over the competition, which generally has welded on skids.
V-Belt Drive
Multi V-belt design enables the transmission of torques between the hydraulic motor and the cutting head.
Hydraulic Hood (HM810 and HM912 only)
The HM810 and HM912 models have a hydraulic-actuated door that allows the operator to control material discharge and finish of the product.
OMM Tube
Stores the OMM (Operation and Maintenance Manual) in a protective case on the attachment, where it can be conveniently accessed. The tooth sharpening gauge can also be stored in the OMM container.
