Claim 9:
10. A reciprocating mower unit configured to be driven by a drive unit via a transmission shaft arranged within a transmission tube, the reciprocating mower unit comprising:
a housing;
a reduction gear arranged within the housing, the reduction gear being configured to receive an input rotary motion from the transmission shaft at a first, relatively higher, rotation speed, and deliver an output rotary motion to a gear output shaft at a second, relatively lower, rotation speed; and
a crank mechanism arranged within the housing, the crank mechanism being configured to convert the output rotary motion of the gear output shaft to an oscillating motion of a pair of mowing blades oscillating in mutual anti-phase about a common oscillation axis, wherein the reciprocating mower unit comprises an input shaft for receiving said input rotary motion from the transmission shaft, wherein the input shaft is provided with a coupling interface for releasably coupling the input shaft to the transmission shaft,
wherein the reciprocating mower unit further comprises a grounding body defining a lowermost face for resting against the ground when the reciprocating mower unit is in use, wherein the grounding body is rotationally decoupled, with regard to turning about the common oscillation axis, from each mowing blade of said pair of mowing blades.
