Kersten Roughcutter flail mowers
Take control of
overgrown ground.
Dedicated pedestrian flail mowers for long grass and dense vegetation. Choose a 65, 80 or 100 cm cut, with hydrostatic travel and steering that help you work around the ground in front of you.
Choose the right machine for the job
Three widths for different working spaces.
Choose width around access, vegetation and the amount of ground you maintain. These are complete dedicated mowers: you do not need a separate two-wheel tractor. Specify the correct blade set with the machine.
Smaller cutting width
RCH 1365 G
A 65 cm cut with the current Honda industrial petrol engine. Its compact cutting width helps work around smaller areas and obstacles.
Choose it when: access and manoeuvring space favour the smallest deck in the range.
Choose the required blade set separately. Confirm wheels, supplied equipment and the complete package price.
Middle-width electric-start model
RCH 1680 G-E
The 16 hp twin-cylinder Vanguard engine and 80 cm deck form the middle option for long grass, verges and suitable banks.
Choose it when: you want an 80 cm cut for mixed mowing routes, with electric start and the higher published slope capability.
Choose the required blade set separately. Confirm wheels, supplied equipment and the complete package price.
Widest electric-start model
RCH 18100 G-E
An 18 hp twin-cylinder Vanguard engine powers the widest listed Roughcutter. Choose it around usable pass width, not engine power alone.
Choose it when: larger open areas make a 100 cm pass useful, and access and transport suit the wider machine.
Choose the required blade set separately. Confirm wheels, supplied equipment and the complete package price.
Measure the whole machine. Cutting width is smaller than overall width. Kersten lists machine widths of 94, 109 and 129 cm respectively; allow clearance at gates and around obstacles. Published slope figures depend on the approved configuration and operating conditions—confirm the suitable setup for your actual site.
Why a dedicated Roughcutter?
Match travel speed to the vegetation.
Slow down where growth thickens
Infinitely variable hydrostatic travel lets the operator adjust forward speed as the cutting load changes, rather than having to choose between fixed walking-speed gears.
Steer through the working area
An axial piston pump and two wheel motors provide hydraulic wheel drive. Hydro-Pro steering helps manoeuvre around obstacles and at the end of a pass; the range is listed with zero-turn capability.
Cut and shred in one operation
The flail rotor cuts vegetation and breaks the cut material down, leaving it on the ground. This suits rough-area maintenance where collection is not part of the required finish.

*Slope capability is not an approval for every bank. Confirm the machine configuration, traction, ground conditions and operating instructions. The separately listed 30° swivel angle is not the 65 cm model’s slope rating.
Plan transport as well as mowing. Check the complete supplied weight, loading access, ramp suitability and vehicle payload. Optional equipment and wheel configurations can change the working dimensions and weight.
Choose around the ground
What does your mowing area need?
Long grass and dense growth
A flail mower is worth investigating where vegetation has outgrown routine lawn mowing. Match blade type, travel speed and cutting height to the actual material and required finish.
Verges, banks and uneven areas
Use the published model capability as a starting point for a site discussion. Traction, obstructions, slope direction and space for the operator all affect suitability.
Explore bank-mowing choices →Wider open areas
The 100 cm model covers a wider strip per pass. Real output still depends on growth density, working speed, overlap and turning time. Choose the widest machine that the site can use effectively.
Choose the cut as well as the mower
Which flails suit the work?
The product listings require a Y-type or boot-type blade set to be selected. The sets below are linked from the Roughcutter product pages: Y-type for rough cutting, boot-type for a finer grass finish. Specify the set for your exact deck and rotor.
Rough-cutting Y-type sets
Choose around heavier vegetation and rough-area maintenance. Confirm suitability for the actual growth; blade choice alone does not establish a woody-stem cutting capacity.

Specify the complete cutting package. Confirm blades, mounting hardware and wheels with the machine quotation. For replacement parts, give the model and serial number so the correct rotor generation and blade fittings can be checked.

Roller, controls and cutting setup.
Optional rear roller
The Roughcutter product pages link these LFRH rear roller options for their respective cutting widths. Specify the roller with the machine and confirm its fitting and effect on the cutting setup.
A roller is not a grass collector. The Roughcutter leaves shredded material on the surface.

Adjust the operator’s position
Vibration-damped, height-adjustable handlebars and an adjustable control console help set the working position. The 80 and 100 cm models also list lateral console adjustment. Try the controls in a demonstration.
Adjust the cutting setup
Four-position height adjustment lets you change the cut for the area and vegetation. Front hollow-chamber wheels support the deck. Ask for the actual height range and supplied wheel configuration for the machine quoted.
Know the resulting finish
Cuttings stay on the ground.
Maintain rough areas without collecting
Shredding and leaving cuttings in place can remove the stop-and-empty part of a mowing routine where the site accepts the remaining material.
Dense cuttings may still need removal if they cover the desired grass or conflict with the site’s maintenance plan. A flail pass does not automatically deliver a restored lawn.
Choose another mowing route when needed
If collection is essential, compare a suitable collecting mower system. If operator access on a bank is the main issue, investigate a remote-control mower. If you want one carrier for mowing and other jobs, compare a modular two-wheel tractor and its attachments.

Before you choose
Your Roughcutter questions answered.
Is the Roughcutter an attachment for my two-wheel tractor?
The RCH Roughcutter is a dedicated self-propelled pedestrian flail mower. You do not need to buy a separate carrier. Choose the blade set and confirm the supplied wheels and optional equipment.
Will the 65 cm model pass through a 65 cm opening?
No. Kersten lists the RCH 1365 G at 94 cm overall width. The 80 and 100 cm cutting models are listed at 109 and 129 cm overall width. Confirm the dimensions of the actual wheel configuration and allow clearance.
Which engine is fitted to the RCH 1365 G?
The current product specifications list an 8.7 kW / 11.7 hp Honda industrial petrol engine. Confirm the supplied engine with your quotation, particularly when comparing older machines and catalogue editions.
Are flail blades included in the listed mower price?
The product pages state that a Y-type or boot-type blade set must be purchased. Ask for the machine, blades, any required fittings, wheels and accessories to be itemised as a complete package.
Does the Roughcutter collect the cuttings?
No collection system is listed for these dedicated Roughcutters. They cut and shred the growth, leaving material on the ground. Assess whether that finish suits the site, or whether clearance or a collecting mower is needed.
Are all three models rated for 30° slopes?
No. The RCH 1365 G is listed up to 20°; the RCH 1680 G-E and RCH 18100 G-E are listed up to 30°. A separately listed swivel angle is a different specification. Confirm approved setup and operating conditions for the actual bank.
What should I send for a recommendation?
Provide access widths, mowing area, slope information, ground conditions, photographs of the vegetation, required finish and transport details. Ask for a demonstration with the appropriate blade and wheel setup.
