JACK Mulcher: The crawler mower for steep slopes.
Remote-controlled, with mulching deck and chain drive for slope gradients up to 100% (45°) – for meadows, slopes, solar parks, and maintenance areas.
The JACK Mulcher is a remote-controlled crawler mower with chain drive and integrated mulching deck, designed for professional landscape maintenance where conventional ride-on mowers and tractors reach their limits. With a 27 HP Briggs & Stratton petrol engine, 80 cm cutting width, infinitely adjustable cutting height from 10 to 150 mm, and an area performance of up to 4,000 m² per hour, it maintains green spaces precisely, safely, and economically.
Why the JACK Mulcher is the right choice
Clean mulching cut
27 HP Briggs & Stratton 2-cylinder petrol engine in a hybrid system delivers a fine, even mulching cut. The cut material remains as natural green fertilizer on the area, no transport, no reworking.
Extreme slope capability
Robust chain drive with steel insert and low center of gravity. Safely masters slope gradients of up to 100% (45°), where classic ride-on mowers must give up at 20°.
4,000 m²/h area performance
Infinitely adjustable cutting height from 10 to 150 mm and high travel speed make even large maintenance areas manageable in one workday.
200 m radio range
Safe operation via radio remote control with emergency stop, automatic shutdown on signal loss, and chain protection curtain. The operator remains at a safe distance from the machine at all times.

Where the JACK Mulcher shows its strengths
The JACK Mulcher is at home wherever regular maintenance is required on difficult terrain – and where a clean cut is important.
Photovoltaics & Solar Parks
Thanks to a height of 80 cm, it can be used under module rows. The closed mulch deck significantly reduces stone throw towards the modules.
Road & highway embankments
Operated from the roadway. One person replaces a classic mowing team of two to three people.
Municipal green spaces
Park embankments, retention basins, noise protection walls, shore areas.
Agricultural hillside meadows
Regular maintenance of slopes where tractors and ride-on mowers cannot operate safely.
Vineyard inter-rows
Narrow alleys and steep vineyard slopes, especially in the southern Styrian wine region.
Landfills & flood protection
Safe maintenance without personal risk on slopes. For flood protection dams and landfill areas.
Practical example: Solar park green maintenance
Steep slope maintenance with full control
The JACK Mulcher works reliably on slopes with a gradient of up to 100% (45°). Thanks to its low center of gravity and wide crawler tracks, the machine remains stable and safe even in extreme terrain.
Using radio remote control, you can operate the mulcher from a safe distance, ideal for embankments, dikes, and steep green areas.
Versatile use
Whether solar park, road embankment, fruit plantation, or municipal green space, the JACK Mulcher adapts to any terrain. The robust mulch deck reliably shreds grass and light growth.
Due to its compact dimensions, the mulcher also reaches hard-to-access areas that cannot be worked on with conventional equipment.
Intuitive radio remote control
The ergonomic remote control allows for precise work from up to 200 m away. All important functions are directly accessible on the controller, for maximum safety and comfort.
The operator remains in a safe position at all times while the machine operates in hazardous terrain.
Frequently asked questions about the JACK Mulcher
What is the JACK Mulcher?
The JACK Mulcher is a remote-controlled mowing crawler with tracked drive and integrated mulch deck. It is designed for the professional maintenance of steep slopes, embankments, solar parks, and municipal green spaces. With 27 HP and a radio range of 200 meters, it safely and efficiently works on areas with a slope gradient of up to 100% (45°).
What slope gradient can the JACK Mulcher handle?
Across the slope up to 100% (45°), uphill and downhill up to 60% (30°). Thanks to its chain drive, low centre of gravity and compact design, it operates safely on uneven ground.
How is the JACK Mulcher operated?
By remote control from up to 200 meters away. The operator stands at a safe distance from the machine during the mowing process. Safety features include an emergency stop switch, automatic shutdown in case of signal loss, and a chain guard curtain.
What is the difference between JACK Mulcher and JACK Flail?
The JACK Mulcher is designed for regularly maintained areas with a fine cut (meadows, solar parks, embankments). The JACK Flail with Y-blades is the more robust specialist for dense vegetation and fallow land. In short: Mulcher for maintained areas, Schlegel for overgrown areas.
What is the area performance?
Up to 4,000 m² per hour – depending on vegetation, terrain slope, and desired cutting height.
Can the JACK Mulcher be used under photovoltaic modules?
Yes. With a height of only 80 cm, the JACK Mulcher can operate under elevated PV modules. The closed mulching deck significantly reduces stones flying towards the modules.
What cutting height is adjustable?
Continuously adjustable between 10 mm and 150 mm – for everything from short-mown lawns to tall wild meadows.
Is the JACK Mulcher also available as a mowing service?
Yes. JACK Works offers a complete mowing service with operator, transport, and operating materials. Details at Mowing service.
How heavy is the JACK Mulcher?
440 kg, light enough for soil-friendly work and quick transport by trailer.
Mulcher or flail? Which model fits your area?
The JACK Mulcher is the right choice for regularly maintained areas with fine mulch cuttings. However, if your areas are characterized by dense vegetation or young growth, the JACK Flail with Y-blades is the more robust tool.
