DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in the figure is a product obtained by folding the present invention into a walk-behind lawnmower 10. The walk-behind lawnmower 10 includes front and rear wheels 1, 1, 2, at four front and rear corners of a deck 3 which is a main frame of the body.
2 is provided, and the driving force of the engine 4 mounted on the deck 3 is transmitted to the rear wheels 2 which are driving wheels to drive the vehicle. The deck 3 is provided with a rotary cutting blade 6, and the engine 4 can be operated by "engagement" and "disengagement" of the clutch 11 with a brake.
The rotary cutting blade 6 is driven by the driving force of to cut grass. In the rear of the deck 3, there is provided a collector bag 7 having a front side opening and the other 5 sides being a net body, and the grass cut by the rotary cutting blade 6 is passed through the transport passage 12 by the rotary wind pressure of the cutting blade and the inside of the collector bag 7 is provided. Send to.

On the left and right of the front part of the deck 3, which is the main frame,
The front support frames 13 and 13 are provided so as to project upward, and the front end portion of the steering handle 8 is pivotally attached 14 to an intermediate portion of the front support frame 13 in the vertical direction. The rear end side of the steering handle 8 extends rearward and upward of the walk-behind lawnmower 10 and is provided with a grip 15 for operating the driver and an operation lever 16 such as a harvesting clutch and a traveling clutch near the rear end. ing. The steering handle 8 at the time of mowing work has the middle portion in the front-rear direction locked to the upper rear portion of the deck 3 which is the main frame with pins 17 and 17 (may be on one side). The operation lever 18 is used to perform one-touch remote operation using wires, rods, etc. (not shown) to operate the steering wheel 8
Can be lifted up for the work described later. A hopper 5 is provided above the engine 4.

The collector bag 7 described above has a locking portion 9
It is attached to the steering handle 8 through the front and rear locking portions 9a and 9b, and when the collector bag 7 is filled with the mowed grass, the pin expansion / contraction operating lever 18 is operated to pull out the pin 17 to operate. When the rear part of the handle 8 is largely moved upward, the collector bag 7 moves upward as shown by the arrow "a" until the steering handle 8 comes into contact with the stopper 32 on the front support frame 13 and is regulated. The turfgrass drops and moves from the front opening into the hopper 5, which is a large-capacity turfgrass storage unit. Reference numeral 19 denotes a guide plate which prevents the grass from dropping from the front opening to a certain position when the collector bag 7 is moved upward, and has a radial shape centered on the vicinity of the shaft attachment 14 of the steering handle 8. The curved plate is a curved plate, and the spring 20 is attached near the lower fulcrum 31 of the guide plate 19 and pressed against the front surface of the collector bag 7.

The lower part of the front end of the hopper 5 is attached to the upper ends of the front supporting frames 13 and 13 by the shafts 21 and 21, and the rear part is made of an elastic material provided on the rear supporting frame 22 provided at the rear part of the deck 3. It is received by the stoppers 23, 23. The hopper 5 is a box-shaped body having a parallelogram shape in a side view with the upper opening and the other five surfaces serving as wall surfaces, and when the handle 25 provided above the rear portions of the left and right side walls 24, 24 is moved upward, the hopper 5 shows an arrow " As shown in "b", it can be tilted forward around the axis 21,
A large amount of stored grass can be collectively thrown away at the weeding place, and the number of times is reduced compared to the conventional case where the collector bag 7 is thrown away every time it is full, and work can be performed efficiently.

The hopper 26 shown in FIG. 2 is of another form and is a trapezoidal box body whose upper part is opened in the front-rear direction, and bag holders 28, 28 are provided inside the upper ends of the left and right side walls 27. By operating the pressure link 29 beyond the fulcrum of the bag holder 28, the upper edge of the large-sized garbage bag 30 made of a resin material such as household nylon, vinyl or polyethylene material is held on the inner surface of the side wall 27. Collects grass in a collector bag 7
It can be treated as household garbage if it is transferred from a to this garbage bag 30, placed on the spot every time it becomes full, and collected later.

When not put in the dust bag 30, it is possible to tilt the shaft 21a forward with the shaft 21a as a fulcrum and throw away the cut grass at the weeding place, as in the first embodiment. FIGS. 5 to 8 show still another embodiment. In a walk-behind lawnmower 10b having no hopper 5, the amount of cut grass in the collector bag 7b attached to the lower portion of the steering handle 8b is shown. , Without trying to open the collector bag 7b, but trying to know from the outside.

When the weight "W" of grass cut in the collector bag 7b attached to one side of the machine body increases, the side of the steering wheel 8b becomes heavier around the rear wheel 2b. By measuring the descending load increase on the side of the steering wheel 8b with the detector 40, the storage amount of cut grass is determined, and whether or not it is necessary to move to the weeding place is known in advance. Detector 40
Is a lever 43 of a leaf spring material attached to a mounting bracket 41 provided at the proximal portion of the control handle 8b by a shaft 42 so as to be swingable, a switch 44 attached to the lever 43, and a display device incorporating a dry battery 45. 46 and lever 4
When the rocking end of No. 3 is pressed and the grass is full and the front and rear are balanced, the switch 44 is energized and the lamp, which is the display tool 46, is turned on to inform the driver of the full state.

[0012]

According to the present invention, the engine 4 is mounted on the deck 3 having the front and rear wheels 1, 1, 2 and 2 at the front and rear four corners, and the hopper 5 having an open upper portion is disposed above the engine 4. Then, the rotary cutting blade 6 is provided inside the deck 3, and the collector bag 7 and the steering handle 8 are provided at the rear of the deck 3. The steering handle 8 is vertically swingable, and the collector bag 7 is partially provided on the steering handle 8. Since the hay storage device of the walk-type lawn mower having the locking portion 9 for locking is provided, the control handle 8 is moved upward every time the collector bag 7 is filled with hay, and thus the hopper 5 is moved into the large-capacity hopper 5. Since the grass can be moved, the number of movements to the weeding place can be reduced, and the efficiency of the mowing work can be reduced. Further, since the hopper 5 has a simple box shape, the content of the grass can be easily discharged only by tilting it forward.
