No. 184618, Utility Model No. 63-27551, Registered Utility Model No.
1764742) is equipped with a clutch and an auxiliary idler wheel.
A drive shaft 4 connected to a prime mover 3 at the top end is supported in a mantle 2 having a diameter, and a bevel gear transmission device 5 is provided in the middle of the drive shaft 4. A clutch 1 is formed by worm-transmitting a traveling axle 8 to which a narrow self-propelled wheel 7 is fixed, and is remotely operated by a lever 9 of a handle 1 on the traveling axle 8.
0, and an auxiliary idler wheel 11 is provided on the opposite side of the narrow self-propelled wheel 7.
It has a flexible structure. 12 is a rotary blade that is interlocked with the drive shaft 4.

かも車輪を介して機体を常に土面に保持するから
作業者の重量負担が著しく軽減される。更に安全
である利点はあるが、傾倒進行の自由を損わない
ために提案された車輪は１輪の狭幅のもので機体
は１点で保持されるため不安定で、長時間作業で
は労力が費され、水平状態での前進も安定性を欠
き、更には車輪は走行軸に直結した走行自走輪の
ため幅の狭い畦畔上での小廻り回転などは難しい
などの欠点は免れない。 The one-wheel drive self-propelled mower that the present applicant had previously proposed (Utility Application No. 184618/1983) can be used to change the angle vertically and horizontally with respect to the uneven mowing ground, just like the shoulder-mounted type. It is possible to tilt the machine vertically, horizontally, and horizontally, and since the machine body is always held on the ground via the wheels, the weight burden on the operator is significantly reduced. Although it has the advantage of being safer, in order not to impede the freedom of tilting movement, the proposed wheel is a single narrow wheel and the aircraft is held at one point, making it unstable and requiring less effort during long hours of operation. However, it lacks stability when moving horizontally, and furthermore, since the wheels are self-propelled and are directly connected to the running axis, it is difficult to make small turns on narrow ridges.

のである。 The present application solves the above-mentioned drawbacks, and by providing an auxiliary idler wheel on the opposite side of the self-propelled wheel, the tilting function of the self-propelled mower, which the present applicant had previously proposed (Utility Application No. 184618-1981), can be improved. It has extremely good straight-line running stability without any loss, and the stability of holding the machine in a stopped state is extremely good, which further reduces labor and further improves stable workability. Therefore, the rotation is positive in the bending direction on the running wheel side and negative in the bending direction on the idle wheel side, and there is no ground resistance of the wheel due to left-right movement even on any uneven surface, and if the diameter of the idle wheel is changed, it can be rotated on a slope. In addition to increasing responsiveness, the power to the running wheels can be switched on and off using the clutch, so mowing can be done freely by stopping the drive at the right place at the right time, and when necessary, it can be used as a two-wheel drive vehicle, so it can be used to cut ridges. It can be rotated freely at any angle at the same position on the ridge, and can be rotated in extremely small turns.
以上の如く走行や作業の安定がよく労力軽減が
大きく更に小廻りが自在である効果がある。 As described above, there are advantages in that traveling and work are stable, labor is greatly reduced, and furthermore, it is possible to turn around freely.
