A walk power mower having a cutting deck supported upon the ground by a front and rear wheel(s). The mower includes a traction drive system incorporating a bidirectional transmission adapted to propel the mower alternatively in both forward and reverse directions. In some embodiments, the mower may include a single bidirectional transmission (e.g., powering only rear wheel(s) or only front wheel(s) of the mower), while in other embodiments, two bidirectional transmissions may be provided to power both the front and the rear wheel(s). In other embodiments, the mower may include a bidirectional transmission powering the rear wheel(s), while the front wheel(s) may be attached to the deck via a caster assembly.

A mower deck belt tensioning arm having a sheet metal body with an idler pulley rotatably mounted to a first end of the body. A spring is connected to a second end of the body biasing the idler pulley against a belt on a mower deck rotating a plurality of blade pulleys. An integrally formed in bushing is between the first end and the second end of the body, the bushing having a straight section length greater than the thickness of the sheet metal body and pivotably mounted around a spindle secured to the mower deck.

The present disclosure relates to a lawn mower (100) comprising a cutter propulsion unit (165), a transmission axle (166, 166′) that has a longitudinal extension (L, L′) and is adapted to be rotated by the cutter propulsion unit (165). The lawn mower (100) further comprises a cutting disc (160) that has a radial extension (R) that runs between a center (182) and an outer edge (181), where the cutting disc (160) comprises one or more cutting edges (161, 162, 163) that are adapted to cut grass when the cutting disc (160) is brought into a rotational motion by means of the transmission axle (166). The cutting disc (160) further comprises a connection portion (164, 164′) which is adapted to receive a coupling member (173, 173′), comprised in the transmission axle (166, 166′), in at least two different mounting positions that are adapted to position the connection portion (164) in mutually separated positions along the longitudinal extension (L, L′).

A lawn mower may include a blade housing configured to house at least a first blade and a second blade, a shaft disposed to rotate within the blade housing, a powerhead configured to selectively turn the shaft responsive to application of power from a power source, and a blade coupler configured to selectively couple the first blade and/or the second blade to the shaft to produce different cutting performance conditions based on which of the first blade and/or the second blade is operably coupled to the shaft.

A mowing machine may include a central cutting deck generally disposed in a neutral mowing plane and a wing cutting deck pivotable with respect to the central cutting deck. A main gearbox may be connected to a wing gearbox by a wing driveline. The main gearbox may be disposed a sufficient distance forward of the central cutting deck and the wing cutting deck to permit the wing cutting deck to pivot about a hinge in a range of motion without disconnecting the wing driveline from either the main gearbox or the wing gearbox.
