Overview
The sleek and imposing dimensions of Spearhead’s STARCUT730 are the first characteristics
of this 7.3 metre width rotary mulcher to impress. The scale and capability of the
STARCUT730 is designed to appeal to large-scale farmers in the UK, Europe, the United
States, Canada and Australia as well as large contractors, municipal users and airport
authorities.
As with the other models in this premium range, apart from the options on cutting
width, the real benefit to professional users is the design and quality of build
and performance, all of which creates higher quality mulching and a more even distribution.
Boasting an abundance of intelligent design features, the full specification of
the STARCUT730 establishes it firmly at the top of its class. The ultimate performance
in grass maintenance, setaside and the heaviest duty scrub clearance is now achievable
far more effectively, far quicker and far more economically.
● Hi-performance 7.3m rotary mulcher
● Super tough chassis & components
● Rugged gearbox can handle high hp
● Covers up to 25 acres an hour
● Suitable for a wide range of crop types

Design
|
The STARCUT mulcher series has been carefully designed to form the stylish characteristic
delta shape. This serves a practical purpose in the collection and distribution
of mulched vegetation creating a far more even spread. A totally new streamlined
exterior also speeds up the cleaning down of the machine post operation. Additional
design features include integrated hose routing; unique monocoque deck structure
and clean input for free material flow. Another key development is the ability to
attach additional rear towing.

Blade Options
|
|
|
|
|
|
|
Designed for heavy vegetation
The HD Series rotor from Spearhead is purpose-built for managing heavy vegetation.
This heavy duty set-up features hardened, updraft blades which are attached to a
reinforced blade holders to enable maintenance in the toughest environment.
|
Designed for crop stubble and grass maintenance
The new MP Series rotor from Spearhead has been specifically designed for mulching
crop stubble and grassland areas. The unique cutting technology greatly reduces
power consumption for maximum efficiency and productivity. Rotors can be tailored
with three or six blade options to suit individual needs.
|
|
|
|
Safety break away
Blade carrier angle ensures blades move up and way from obstacles and also minimises
stone throw even when cutting at ground level.(MP series blades only)
|
|
|
|
|
|
|
Three-blade configuration
The large and durable design of the HD3 blade makes them ideal for mulching dense
vegetation. A larger blade carries greater momentum which cuts through denser material
far more effectively and efficiently.
Heavy duty blades
Hardened, heavy duty blades are specifically designed for maintaining dense growth.
Up-draft wing tips lift flattened material and circulate the chopped crop within
the deck for maximum mulch.

Six-blade Configuration
The MP6 is the rotor of choice for efficient stubble management solution. All the
benefits of the MP3 are enhanced with the addition of three further mulching knives
doubling its operational capability. The blades are set on two cutting planes to
ensure vegetation is mulched even more finely for accelerated decomposition.
|
|
|
|
|
|
Improved decomposition
Blades and additional mulching knives mix fine soil particles with well
mulched material. This produces the perfect environment for fast decomposition.
It also encourages unwanted volunteers to germinate.
