摘要： PURPOSE:To make it possible to reinforce the strength in the lengthwise direction of a bumper by spanning a muffler cover made up in a sheet metal construction over the front side section of a bumper and the front end of a body frame. CONSTITUTION:A muffler cover 3 is made in a sheet metal construction in such a integral shape that a muffler proper 2 is covered from front and back and from right and left and from the lower part. The muffler cover is spanned over the front side section 9a of a bumper 9 and the front end of a frame 7. The bumper 9 and the frame 7 is jointed with the muffler cover 3 whose rigidity in the front and back directions is remarkably improved as above, so that the strength of the bumper 9 in the front and back direction can be decreased.

摘要： PURPOSE:To facilitate attachment and detachment of the blower unit to increase the durability of the transmission mechanism by energizing the blower on the gear case side of the mower to drive the shaft. CONSTITUTION:The output shaft 16 extending in the obliquely backward direction is connected through a bevel gear to the gear case for rotation and driving. The output shaft 16 is connected through a shaft transmission mechanism A comprising a couple of universal couplings 18, an intermediate shaft 20 which is supported with a plummer block 19 which is a bearing having aligning action and a coupling 21 to the inlet shaft 17 for driving the blades 13b. Thus, the power can be transmitted with improved durability and reduced transmission loss.

摘要： PURPOSE:To facilitate the check, maintenance and cleaning of the lawn mower by providing the mower with a mechanism for fixing uprightly the link unconnected from the running body to one end of the mower. CONSTITUTION:When it is fixed uprightly to the rear end of the mower 6, the rear link 6 is swung to the upright posture and a screw having a knob is inserted through the long hole 10 to the tapped hole 9. Then, the rear link 6 is swung backward around the roller 13 beneath the rear link 6 whereby operations such as exchange of blades or the like can be easily done.

摘要： PURPOSE:To facilitate attaching of a grass-collecting vessel to the main body of a mower, by using a stationary frame to support a grass-collecting vessel and providing the frame with an engaging part to enable the engagement and disengagement of a supporting frame of the main body. CONSTITUTION:A pair of independently detachable supporting frames 10 are detachably attached with an engaging pin 12 to a rear opening end 11A of a main frame acting as a pair of attaching parts attached to the main body of a mower. A fixing frame 13 to support a grass-collecting vessel 8 is linked and fixed to an upper opening 10A of the supporting frame 10. An engaging part 13a constructed of a pair of left and right pipes protruded downward from the fixed frame 13 is inserted into the upper opening 10A of the frame 10. The grass-collecting vessel 8 is set in such a manner that a head 8A attached to the circumference of the upper opening of the top-opened grass-collecting vessel 8 is placed from above and contacted to a pipe frame 13A and a channel frame over the whole circumference.

摘要： PURPOSE:To detect the fully packed state of a grass-collection bag irrespective of the collection density of the mowed grass, free from the influence of floating material such as waste lawn, by setting a full-bag detection sensor in a state to be brought into contact with a mowed grass-holding part of a grass-oscillation bag which is bulged when fully packed. CONSTITUTION:A mowed grass-holding part 8B of a grass-collection bag 8 is bulged outward according to the amount of collected grass. A sensor (limit switch, pressure sensor, etc.) actuated by contacting with said bulged part is placed to enable the detection of the bulged amount of the grass-collection bag according to the fully packed state.

摘要： PURPOSE:To increase the pressing force of an openable cover against a fixed frame, by using an openable cover closing an opening of a grass-collecting vessel and rotatably pivoting the cover to a bracket fixed to a supporting frame. CONSTITUTION:A pair of right and left brackets 16, 16 each having an engaging hole 16a are fixed to a lower side flange 15A of a supporting frame 10 of an openable cover 15. A plate 17 attached with a protruded headed pin 17a is protruded from the supporting frame 10. The pin 17a is fit to the engaging hole 16a and the cover 15 is made to be vertically swivellable around the pin 17a. The cover 15 is placed on the fixed frame 13 or on a fitting of the grass- collecting vessel 8 and laterally shifted to insert the pin 17a into the engaging hole 16a. Separately, a hooking tool is attached to the lower end of the cover 15 opposite to the bracket 16 and a hooking fitting 19 fixed to a channel frame 13B of the fixed frame 13 at one end is engaged to a hooking tool to keep the cover in closed state.
