Abstract
A lawnmower cutting deck (1) is disclosed, wherein the cutting deck (1) is configured to be moved in a forward direction (d1) over a ground surface (5) to cut grass. The cutting deck (1) comprises at least a first cutter shaft (7.1) and at least one cutting unit (9) arranged on the first cutter shaft (7.1). The first cutter shaft (7.1) is configured to rotate around a first rotational axis (ax1) extending substantially parallel to the ground surface (5) to rotate the at least one cutting unit (9) in a first rotational plane (p1). The first rotational plane (p1) is angled in relation to the forward direction (d1). The present disclosure further relates to a lawnmower (3, 3′) comprising a lawnmower cutting deck (1) and a method (100) of mowing a lawn.
Claims23
A lawnmower cutting deck, wherein the cutting deck is configured to be moved in a forward direction over a ground surface to cut grass, the cutting deck comprising:
- a first cutter shaft;
- a first cutting unit arranged on the first cutter shaft;
- a second cutter shaft;
- and
- a second cutting unit arranged on the second cutter shaft;
- wherein the first cutter shaft is configured to rotate around a first rotational axis extending substantially parallel to the ground surface to rotate the first cutting unit in a first rotational plane;
- wherein the first rotational plane is angled in relation to the forward direction at a first angle;
- wherein the second cutter shaft is configured to rotate around a second rotational axis extending substantially parallel to the ground surface to rotate the second cutting unit in a second rotational plane;
- wherein the second rotational plane is angled in relation to the forward direction at a second angle;
- wherein the first cutting unit comprises a rotor and a cutting member arranged on the rotor at a distance from the first rotational axis;
- wherein the cutting member is pivotably arranged on the rotor;
- wherein the second angle is opposite the first angle;
- and wherein the first and second cutter shafts both lie in a same horizontal plane.
