A mower including a plurality of cutter blades is disclosed. The mower includes a housing accommodating the cutter blades. The housing includes a first a first side face defining a discharge opening for discharging grass clippings, a side panel formed at a second side face disposed on the opposite side to the first side face relative to a longitudinal center line of a vehicle body, and a front panel having a first front panel disposed on the side of said discharge opening, and a second front panel including a flat extension portion extending on the opposite side to the discharge opening. The flat extension portion extends substantially to a virtual line extending from an outer side end of a locus of revolution of the blade disposed adjacent the second side face in parallel with a traveling direction of the vehicle body.

Mower apparatus

A mower unit includes a plurality of blade mechanisms each having a blade and a blade shaft fixed to the blade for supporting the blade, pulleys and a belt for transmitting drive among the blade mechanisms, a plate-like support frame for interconnecting the blade mechanisms through intermediate members, a mower deck, and vibration proofing rubber elements disposed between the mower deck and the blade mechanisms.

Mower blade mounting structure

A mower unit having a bevel gear mechanism includes an input shaft extending substantially horizontally; a first bevel gear mounted on the input shaft; an output shaft extending substantially vertically; a second bevel gear meshed with the first bevel gear and mounted on one end of the output shaft; a blade mounted on the other end of the output shaft; a blade housing coveting the blade and defining an opening for receiving the output shaft; a beating holder rotatably supporting the output shaft; a bevel gear case containing the first and second bevel gears; and a pair of fight and left support stays connected to the bevel gear case for mounting the bevel gear case to the blade housing. The bearing holder and support stays are interconnected by reamer bolts, with the blade housing interposed between flange surfaces formed on the beating holder and flange surfaces formed on the support stays. Soft metal packings are interposed between the flange surfaces of the support stays and upper surfaces of the blade housing.

Mower unit having a bevel gear mechanism

A mower unit includes a housing having a skirt portion extending toward the ground, and a covering wall surrounding a plurality of grass cutting blades to define spaces for mulching treatment. The covering wall includes peripheral wall members each curved along a locus of revolution of the blade and spaced from the skirt portion. The peripheral wall member includes a vertical portion descending toward the ground. The vertical portion and the skirt portion have lower ends thereof substantially at the same height over the ground. The blades are arranged transversely of the mower unit. The peripheral wall members are in the form of independent annular wall members provided for the blades, respectively. The annular wall members define spaces for mulching treatment substantially independent of one another. Alternatively, the peripheral wall members may be in the form of annular wall members corresponding to loci of revolution of the blades, respectively, and an adjacent pair of the annular wall members may have at least parts of peripheries overlapping each other. The parts of peripheries are cut so that the spaces of mulching treatment defined by the pair of annual wall members communicate with each other.
