Riding mower

A mower includes: a left panel positioned on a left side of a driver's seat. The driver's seat is positioned rearward of a mower unit. A display unit is arranged in an area of the left panel. A line linking a left front corner area of the mower unit and a top center portion of a seat back of the driver's seat passes through the display unit. The display unit is arranged so that a screen of the display unit faces the top center portion of the seat back.

Riding mower with improved operation visibility

The grass mower includes a front wheel unit having a left front wheel and a right front wheel which are mounted to a vehicle body frame, a rear wheel unit having a left rear wheel and a right rear wheel which are mounted to the vehicle body frame and a mower unit disposed between the front wheel unit and the rear wheel unit downwardly of the vehicle body frame, the mower unit including a rotary blade unit that has at least a left blade and a right blade which are disposed side by side in a vehicle body left/right direction. The rotary blade unit is configured such that a tread-on track of the left front wheel is overlapped with a rotation locus portion of the left blade from the front side to the rear side thereof and a tread-on track of the right front wheel is overlapped with a rotation locus portion of the right blade from the front side to the rear side thereof.

Grass mower

A working vehicle has a cooling fan provided on a first side of an engine to blow air to the engine; a muffler main body provided on a second side thereof in a position lower than an upper surface of a head cover of the engine; and an exhaust pipe exposed in a position facing an air blowing path of the cooling fan higher than the upper surface of the head cover of the engine to discharge exhaust from the muffler main body.

Working vehicle

An exhaust gas temperature detection sensor is arranged at a predetermined position outside a muffler, or at a predetermined position outside an exhaust pipe constituting an exhaust gas flow passage on a more downstream side than the muffler in an exhaust direction. The sensor detects that an atmosphere temperature at the predetermined position outside the muffler has reached a predetermined temperature based on an increase in a temperature inside the muffler, or detects that an atmosphere temperature at the predetermined position outside the exhaust pipe has reached a predetermined temperature based on an increase in a temperature of an exhaust gas inside the exhaust pipe.

Engine exhaust heat temperature detection device

A dust removal system for a riding lawn mower, comprising an engine, a speed change device disposed outside of an engine compartment, and a universal coupling inserted through an opening provided to a separating wall in order to connect an output shaft of the engine and an input shaft of the speed change device. The dust removal system is composed of a perforated board which rotates integrally with the output shaft and around the axis of the output shaft in order to impede grass cuttings from flowing into the engine compartment through the opening, the perforated board having an insertion hole formed in the center to allow the universal coupling to be inserted; and a seal unit for substantially sealing the space between the universal coupling and the peripheral edge of the insertion hole. The seal unit has a radially extending flange formed on the universal coupling, and a ring member in which one end is mounted on the flange and the other end is in contact with the peripheral area around the insertion hole.

Dust removal system for a riding lawn mower

Disclosed is a mower with a mower deck, a plurality of cutting chambers mutually communicated and arranged in a lateral direction within the mower deck, and a blade mounted in each cutting chamber to be rotatable about a vertical axis. A grass clippings guide in form of a vertical wall is disposed in an upper area within the cutting chamber, to guide the grass clippings flowing within the cutting chamber toward a center of rotation of the blade. A shield member is disposed for preventing entry of grass clippings between the grass clippings guide and a peripheral wall of the cutting chamber.

Mower having a grass clippings guide and shield member

A mower tractor includes a vehicle body supported by a plurality of wheels; an engine mounted to the vehicle body; a mower suspended from the vehicle body; at least one grass collector bag for collecting grass cut by the mower; a grass collector bag holder supporting said at least one grass collector bag at a position on one side with respect to the engine; and a stopper portion for abutting against the grass collector bag so as to prevent the grass collector bag supported by the grass collector bag holder from moving toward the vehicle body.
