Description

[Detailed description of the invention] [Industrial application field] The present invention relates to improvements in lawn mowers.

[Conventional technology]

In this type of lawn mower, conventionally, a mower provided between the front and rear wheels and a grass collector provided at the rear of the machine body are connected by a discharge duct that bypasses the lateral outer side of the machine body.

[Problem that the invention seeks to solve]

However, in this case, the exhaust duct protrudes outward from the side of the machine, resulting in an increase in the actual width of the machine, making it less applicable to narrow workplaces.

It is an object of the invention to provide a solution to the conventional drawbacks by effective positioning of the discharge duct.

[Means for solving the problem] The characteristic configuration of the present invention is that a mower is disposed between the front and rear wheels, a grass collector is provided at the rear of the machine, and cut grass from the mower is supplied to the grass collector. The exhaust duct is located within the gap between the rear wheel and the fender, and its effects are as follows.

[Effect]

In other words, by positioning the exhaust duct below the fender, it can be positioned within the original width of the machine body, and the actual width of the machine body can be made smaller compared to the conventional configuration, so it can be used in narrow workplaces. Reaping travel is possible even at wide areas.

Furthermore, since the discharge duct is located above the rear wheel, it can be connected to the grass collector at its upper part, and the cut grass from the mower can be dropped into the grass collector from the upper intake port. Since the grass can be supplied in bulk, it is possible to increase the density of grass collected in the grass collector.

〔Effect of the invention〕

As a result, mowing can be carried out even in narrow spaces, expanding the work area and improving work efficiency. At the same time, by increasing the collection density of cut grass into the grass collector, the capacity of the grass collector can be fully utilized. It is possible to reduce the number of stops required for discharging after the tank is full.

However, it is conceivable that the exhaust duct be located between the rear wheels to achieve the same effect, but in this case, since the exhaust duct is located inside the vehicle body, it is located on the side side compared to this. The device of the present invention, which is open toward the outside of the machine, allows for easy installation and removal of the discharge duct when performing maintenance work due to clogging of cut grass, and reduces the burden on the operator.

〔Example〕

As shown in FIG. 4, an engine 2 and a fuel tank 3 are provided in the hood 1 at the front of the fuselage, and a control section 7 is formed at the rear with a control handle 4, a driver's seat 5, and a flat deck 6 on the left and right sides. The machine is supported by the front and rear wheels 8 and 9 and can be moved for reaping.
In addition, the lawn tractor is equipped with a mower 10 located between the front and rear wheels 8 and 9, and a discharge duct 11 and a grass collector 12 extending rearward from the mower 10 between the left and right rear wheels 9 and 9. It is configured.

To explain the transmission mechanism in detail, output pulleys 14 and 15 are arranged in upper and lower stages on the downward output shaft 13 of the engine 2.
The lower output pulley 15 and the input pulley 16 fitted to the input shaft of the mower 10 are connected by a belt 17 to form a working device transmission mechanism. On the other hand, an input pulley 20 of a transmission case 19 is connected to the upper output pulley 14 via belts 21 and 22 via a continuously variable belt transmission 18, and rear wheels 9 and 9 pivotally supported at the lower end of the transmission case 19 are connected to the upper output pulley 14. A traveling transmission system is configured to be drivable.

The discharge duct 11 is the discharge port 10 of the mower 10.
The entrance part where A is fitted externally and the intake port 12A of the grass collector 12
The outlet portions to be inserted into the interior are respectively made into a double pipe structure, and the outer movable ducts 23 and 24 of the double pipes are fitted onto the main body duct so as to be slidable and fixed in the axial direction thereof. It has been done.

The mower side movable duct 23 has an opening area large enough to accommodate the vertical movement of the mower 10, which moves up and down as the cutting height changes.

Discharge duct 1 having such an entrance/exit structure
1 above one rear wheel 9 and the fender 25
The grass collector 12 is connected to an intake port 12A provided at the upper part of the grass collector 12.

In the figure, reference numerals 26 and 26 are metal fittings for attaching the discharge duct 11, and when removing the discharge duct 11, the movable ducts 23 and 24 are slid to engage the mower 10 and the grass collector 12. Release and remove metal fittings 2
All you need to do is remove 6 and 26.
