Perfect mulching

STIHL mulching mowers are based on the rotary mower principle. On this page we explain how they work and show you the mulching mowers available from STIHL.

How STIHL Mulching Mowers work

The cut grass is chopped up several times by a special multi-blade and air flow routing in the cutter area to produce very tiny bits of grass. The cuttings are evenly distributed and left lying almost invisibly on the lawn where they will soon rot down and perform a fertilizing function.

STIHL Lawn Mowers

Some STIHL lawn mowers (RM 545 VM, RM 650 T/V, RM 655 V/VS), are multi-talented machines. With the grass box in place they give a high quality collected cut - just like a standard rotary mower. Remove the grass box, insert the mulch 'plug' and they are transformed into efficient mulching machines, with grass clippings deposited back into the lawn. Grass cuttings can also be discharged to the rear. The majority of STIHL lawn mowers can be converted to mulchers with an accessory mulch blade and plug kit available.

The R Series specialists are ideal for mowing rough grass and areas where you don't want to collect cuttings. The lightweight RM 2 R model is a dedicated mulch mower - perfect for small gardens. The RM 4 RT is a more powerful mulching mower, for medium-sized gardens. And the RM 4 RTP is a professional mulcher with a foldable handlebar, low emissions and able to cover up-to 2500 m² - making it perfect for cutting longer grass throughout the day.
