Mulching Heads
IMH
lndeco's IMH series of hydraulically-driven, boom-mounted
mulching heads has been designed to turn excavators and
miniloaders into powerful land-clearing tools, facilitating
the felling and clearing of vegetation, greatly reducing
costs and time. Available for a wide range of machines from
3 to 36 tons, the IMH mulchers are made with HARDOX®
components that ensure excellent durability and efficiency.
Powerful and easy to handle, they let you work quickly
and precisely, guaranteeing the best results with the
minimum use of personnel in the most diverse applications.
IMH mulchers are perfect tools for the cleaning and
periodic maintenance of areas invaded by spontaneous
vegetation such as pipelines, railway lines, ski slopes,
electricity pylons, roadways and motorways, residential and
commercial green areas. Very useful in all operations for the
maintenance of green areas, elimination of undergrowth,
creation and maintenance of paths and firebreaks, clearing
of trees, vegetation, and branches, the IMH mulchers
are also ideal tools in special applications that require
natural landscape reshaping such as the creation and
maintenance of golf courses, hedgerow rejuvenation, and
the removal of stumps, roots, and wood residues of various
kinds. In addition to carrying out their work quickly and
effectively, an aid to protect and naturally fertilize the soils,
reintroducing unwanted vegetation into the ecosystem in
the form of mulch. This way, the soil is protected from wind
and rain erosion and at the same time nourished with
fertilising microorganisms.
Characteristics of lndeco's
Mulching Heads
The multiple V-belt drive 11 I guarantees maximum
reliability, power and ease of maintenance. Direct drive
models are also available.
The hydraulic motor 121 can have fixed or variable
displacement depending on the models. The high
performance FD fixed displacement motor (gear on some
models, piston on others) has special high pressure resistant
seals and is capable of accepting back pressures. The VD
variable displacement piston motor, only currently in use
on some versions, adapts more to the various hydraulic
specifications of the machines, minimises overheating by
improving pick-up, optimises torque and rotor speed and
maximises productivity.
The particular design of the teeth, of different types,
their number and position on the teeth holder 131 have
been designed to offer the best possible grinding of the
material, increasing the productivity and stability of the
tool. In addition, special 141 "bite limiter" wear-resistant
steel profiles, welded on the drum in correspondence of
the teeth, make it possible to make the cutting depth more
efficient and the rotation speed more constant, ensuring
greater continuity in work and better performance.
The body and components in HARDOX® ISi ensure
maximum sturdiness and long service life, even when used
in particularly heavy-duty applications.
The Heavy Duty rotor 161 ensures prolonged efficiency over
time, in any type of application.
The runners in HARDOX® 171 offer effective protection for
those parts subject to wear.
Direct access to the monobloc shaft ISi helps to keep the
mulching head perfectly efficient, facilitating maintenance
operations on the bearings and components of the shaft
itself.
The pressure and flow limiting valve 191 allows safe
and fast installation, preventing incorrect set-ups from
compromising productivity and the life of the mulching
head. The safety and anti-cavitation valve protects the
motor from possible incorrect connection of the pipes and
therefore from unexpected flow reversals, extending the life
of the seals.
The centralised hydraulic connections, the drainage line
and the greasing points 1101 are visible to the operator
during use thereby allowing constant checking of correct
functioning of the tool.
The interchangeable assembly points 111 I allow maximum
flexibility of use with any excavator.
Direct access to the motor and hydraulic connections 1121
facilitates maintenance interventions.
