Which model for which lawn
For each lawn size, the STIHL model the sizer puts first in each market: the smallest limit that still covers the lawn with its margin. The lawn is of typical shape (× 1.35), mowed at any time, on a gentle 15% slope. The table ranks the 3 STIHL models in the Botsize dataset only.
| Lawn | In the EU |
|---|---|
| 250 m² (2,690 sq ft) | iMOW 4 EVO |
| 500 m² (5,380 sq ft) | iMOW 4 EVO |
| 1,000 m² (10,760 sq ft) | iMOW 5 EVO |
| 1,500 m² (16,150 sq ft) | iMOW 7 |
| 2,000 m² (21,530 sq ft) | iMOW 7 |
| 3,000 m² (32,290 sq ft) | iMOW 7 |
| 5,000 m² (1.24 acres) | iMOW 7 Tight |
Tight means the rating covers the lawn but not the margin. Your own lawn may differ in shape, slope and hours: the mower sizer checks it with your numbers, and the methodology states the rules.
