Start by deciding what you will be cutting. For a regularly mown lawn, choose a petrol lawn mower with a grass bag: match the cutting width to the area, the drive to the terrain and the cutting height to the season. Tall grass, weeds and overgrowth need different equipment: a self-contained flail mower (mulcher) or a rotary mower attached to a two-wheel tractor. Our mowers category contains both types, so below we separate them clearly.
Lawn or tall grass: two different types of machine
| Lawn mower | Flail mower (mulcher) | Two-wheel tractor mower | |
|---|---|---|---|
| Purpose | regularly mown lawn | tall grass, weeds, shoots, small shrubs | meadow, hay, overgrown plots |
| Catalogue example | Sigma Garden 53 cm 5.75 HP | Grünwelt GWX700 | Weima WMKM900, WMKM1100-6 |
| Width | 53 cm | 70 cm | depends on model |
| Cutting height | 25–75 mm | 5–50 mm | depends on model |
| Cut grass | 62 l bag, mulching or side discharge | shredded by 36 hammer flails | left in a swath |
| Drive and weight | 32.5 kg | own gearbox: 3 forward, 1 reverse; 180 kg | from the tractor's PTO |
Figures from the product pages. A lawn mower is not designed for overgrown ground, while a mulcher or rotary mower will not give you a neat, bagged lawn.
Lawn mower: what to look at
Cutting width and lawn size
Width determines the number of passes. As a rough guide: up to about 300 m², 40–46 cm is enough; for 300–800 m², aim for 46–51 cm; above 800 m², 51 cm or more. In a garden with many trees and beds, a narrower mower is more agile and leaves fewer uncut "islands".
Drive: push or self-propelled
A push mower is lighter and simpler. Wheel drive helps on large areas and slopes, where pushing quickly becomes tiring. Before buying, check on the product page whether the model has drive.
Engine power
A stronger engine copes better with dense and wet grass. Example: the Sigma Garden 53 cm has a 173 cc four-stroke OHV engine rated at 5.75 HP. The set includes 0.6 l of SAE 30 oil, but you must fill it yourself before the first start, following the manual.
Bag, mulching, side discharge
- A grass bag leaves the lawn clean but needs emptying.
- Mulching shreds the clippings and leaves them on the lawn; it requires more frequent mowing.
- Side discharge is handy for taller grass.
The Sigma Garden 53 cm offers all three: a 62 l bag, a mulching insert and side discharge.
Cutting height
A wide adjustment range lets you cut shorter in spring and leave the grass longer in hot weather. The Sigma Garden 53 cm adjusts from 25 to 75 mm.
Mulchers and two-wheel tractor mowers: for tall grass
The Grünwelt GWX700 and the WEIMA WMX663 list identical specifications: 70 cm width, 5–50 mm cutting height, 9 HP engine, 3 forward gears and 1 reverse, 6.5 l tank, 180 kg. They differ in warranty (12 months on the GWX700 page, 24 months on the WMX663 page), price and availability. GWX700 wheels are shipped deflated: inflate them before first use, as damage caused by skipping this is not covered by the warranty.
If you already own a two-wheel tractor, the cheaper route is a rotary mower attached to it, for example the Weima WMKM900. For hay there is also the Weima WMSM1100 sickle bar mower. Check compatibility with your tractor model on the product page or ask us by phone. We also list Jansen flail mowers and tall-grass mowers (for example HSM-60, HGM-58) and Jansen tractor attachments; their current status is "expected".
The mowers category also includes the Grünwelt GW-44F-5A 5-in-1 multi-tool (two-stroke engine, 1:25 fuel mix). It is a brush cutter for edges and tight corners, not a lawn mower.

Frequently asked questions
Can I cut a meadow or an overgrown plot with a lawn mower?
It is not designed for that. For tall grass and weeds choose a mulcher (for example the Grünwelt GWX700) or a rotary mower for a two-wheel tractor.
What is the difference between the Grünwelt GWX700 and the WEIMA WMX663?
Their listed specifications are the same (70 cm, 5–50 mm, 9 HP, 180 kg). They differ in warranty, price and availability.
What cutting height should I use?
On a lawn use the adjustment, for example 25–75 mm on the Sigma Garden 53 cm: shorter in spring, higher in hot weather. The GWX700 and WMX663 mulchers adjust from 5 to 50 mm.
Is the mower delivered with oil?
The Sigma Garden 53 cm set includes 0.6 l of SAE 30 oil, which you fill yourself before starting. For other models, check the product page. Regular engine care is covered in our guide two-wheel tractor and engine care.
Does a rotary mower fit any two-wheel tractor?
No. Compatibility depends on the tractor model and its PTO; check the product page or call us.
