Effortless Mowing, Even on Tough Terrain

Easy Grass Collection and Mulching
No more frequent emptying — the Classic 20S features a spacious 60-litre grass collector to hold more clippings, saving you time. If you want to give your lawn a boost, simply use the mulching plug (it’s included!) to finely chop the clippings and spread them back on your lawn, returning nutrients as you mow.

Faqs

Is the product already assembled in the box?
The product is almost fully assembled when you open the box. The main parts have been put together and the remaining elements are easy to assemble. Follow the directions in the instruction manual to ensure the grass cutter is assembled correctly.
Is the instruction manual in the box for this petrol lawnmower?
The instruction manual is included in the box of this petrol lawn mower. The instruction manual can also be viewed or downloaded from the STIGA website, accessible from the "Manuals" section of the product page.
What is the cutting height set to on this petrol lawn mower?
The cutting height can be adjusted according to desired grass length. If the grass is very long, we recommend first mowing the lawn with the cutting deck in a higher position. Then, mow the lawn a second time with the cutting height set to the desired grass length. For information on cutting height positions, refer to the "Technical specs" section. Read the instruction manual carefully.
What cutting deck height is recommended for the mulching function on this petrol mower?
The mulching system of this petrol lawnmower allows you to cut the grass into fine pieces, which remain on the lawn, restore nutrients and support growth.
To use this function, turn off the engine, remove the bag, insert the mulching plug provided and set the chassis height so that the grass will be cut to a length that does not exceed a third of the total grass height of the lawn.
Do I have to remove the bag to use the side discharge function on my petrol lawn mower?
To use the side discharge function on this petrol mower, you need to remove the bag, attach the mulching plug and join the deflector to the side of the cutting deck. You can re-attach the bag to the lawn mower, but it is not required for use in side discharge mode.
