Apparatus for cutting grass comprising: a lawn mower (1), provided with: a frame (10); one or more blades (30) mounted on said frame (10); movement means (20) mounted on said frame (10) for movement of said lawn mower (1). The apparatus (200) also comprises a perimetral structure (100) comprising at least a perimetral wire (110) delimiting a cutting area (S). The lawn mower (1) also comprises a transmission module (40) for emitting an electromagnetic field (EM). The perimetral structure (100) is configured such as to: detect said electromagnetic field (EM) via said perimetral wire (110); supply, via said electromagnetic field (EM), an electrical signal (ES) propagating in said perimetral wire (110). The lawn mower (1) further comprises a detection module (50) for detecting said electrical signal (ES). The lawn mower (1) further comprises a processing unit (60) for comparing said electrical signal (ES) with one or more pre-memorised parameters (P) and generating a control signal (CS) for said movement means (20) as a function of said comparison.
