An example of a riding rice transplanter is shown in which a planting section 8 including a erected seedling platform 7 and the like is connected via a lifting link 9 and a hydraulic cylinder 10 so as to be able to move up and down. The traveling body 3 has a short wheelbase and a small amount of overhang at the front of the body, and has a body configuration that is as small and compact as possible and has a small turn. Reference numeral 11 denotes a body frame to which an auxiliary step 11a is integrally attached. The body frame 11 has a rigid frame mainly composed of a square pipe, and its upper surface has a driver's seat step 12a, a rear huender 12b, a front step 12c, and a front part. The cover 12d and the like are covered by a cover body 12 integrally formed. An opening 12e for a clutch pedal is provided on the front left side of the driver's seat step 12a, and an opening 12f for the brake pedal is provided on the front right side. P is an anti-slip member (non-slip sheet) attached to the upper surface of the driver's seat step 12a and the front step 12c, and is designed to safely move on the steps and get on and off the body 3. 13 is a hood, 14 is a steering handle,
15 is a driver's seat, 16 is a clutch pedal for stepping operation,
Reference numeral 17 is a brake pedal. 16a and 17a
A pedal arm disposed below the step 12a.
To avoid interference with the traveling mechanism
Largely protruding below driver's seat step 12a during operation
So as not to move forward from the driver's seat side to the front of the fuselage from the driver's seat side through the openings 12e and 12f , respectively.
Are protruded to the rear inclined, each pedal arm 16a, 1
The base end of 7a is pivotally connected to the body frame 11 side via a bracket or the like so as to be vertically rotatable. The symbol a indicates the direction in which the pedals 16 and 17 are depressed.

Reference numeral 18 denotes an auxiliary seedling stand disposed on the front left and right outer sides of the traveling machine body 3. The auxiliary seedling stand 18 is detachably attached to the traveling machine body 3 via two front and rear stays 19 and 19 a. ing. At the lower ends of the front and rear stays 19 and 19a, rods 20 and 21 are integrally provided so as to protrude inward. The front rod 20 is inserted into a pipe 22 fixed to the lower surface of the front end of the body frame 11. The rear rod 21 is fixed behind the pipe 22 and forward of the front wheel axle 1a, and is fixed to an L-shaped mounting seat 23 fixed to the body frame 11 with a bolt 24. In this embodiment,
Although the front and rear stays 19 and 19a are illustrated as having a deformed U-shape that is integrally curved via the horizontal portion 19b at the upper end, the front and rear stays 19 and 19a may be separate bodies. Numeral 18a is a seedling receiver on which a seedling box is placed, and is mounted on the front and rear stays 19 and 19a in a cantilevered manner in a plurality of stages (two stages in this embodiment). M is the left and right stays 19a,
Markers attached to the outside of 19a.

By the way, the opening 1 for the clutch pedal is provided.
On the rear side of the opening 2e and the opening 12f for the brake pedal, there is provided an upwardly curved cover 25 that covers the upwardly projecting base end sides of the pedal arms 16a and 17a from above.
In this embodiment, the cover 25 is provided integrally when the cover 12 is formed. However, a separate cover may be attached to the cover 12 by a retrofitting method. Although the cover 25 is inclined forward and upward along the direction in which the pedal arms 16a and 17a protrude, the upper surface of the cover 25 corresponds to the heel at the time of a stepping operation, so that a sense of stability can be provided and operation can be performed. Care is taken to make the curved surface as gentle as possible to improve the feeling.

In the above configuration, the clutch pedal 16 and the brake pedal 17 are set during planting work or running on the road.
When the pedal is depressed, the foot is put on the pedal 16 or 17 and the pedal is depressed. The upwardly projecting bases of the pedal arms 16a and 17a are respectively provided on the rear sides of the clutch pedal opening 12e and the brake pedal opening 12f. Since the upwardly curved cover 25 that covers the end side from above is provided,
The opening area of each of the openings 12e and 12f is reduced, so that the foot can be moved to the opening 12e or 12f when the pedal is depressed.
There is no such thing as getting into. The same applies when replenishing seedlings or getting on / off the aircraft.

When the brake pedal 17 on one of the left and right sides is depressed, the cover 25 guards the protruding base ends of the pair of left and right pedal arms 17a from above.
Right brake pedal side pedal arm 17a or left brake pedal side pedal arm 1 adjacent to the heel portion of the stepping side foot
An erroneous operation of inadvertently stepping on 7a can be eliminated.

Furthermore, since the cover 25 is located behind and below the pedals 16 and 17, when the pedals 16 and 17 are depressed, the cover 25 also serves as a cradle for supporting the heel portion of the foot on the side of the depressed side. It is convenient.

Further, as in the case of the conventional riding mobile agricultural machine, the pedal arms 16a and 17a
In the case of the structure which is directly exposed above the pedal arm 16a, 17a, the projection length of the pedal arm 16a, 17a becomes longer, and the foot may be hooked on the pedal arm 16a, 17a when getting on or off the machine. In a small riding mobile agricultural machine having a short distance, the driver's seat step 12a (particularly, the width of the front and rear steps) is limited by space, so that the pedal arms 16a and 17a are likely to be obstructive when getting on and off the machine. By covering the protruding base ends of the arms 16a, 17a from above along the inclination of the pedal arm with the cover 25, the protruding length (exposure length) of the pedal arms 16a, 17a onto the driver's seat step 12a is reduced. In addition, the cover 25 can move the portion of the exposed arm closer to the driver's seat 15 from the upper surface of the step 12a to the pedal arm.
Cover 25 is bulged upward along the slope of the system, so that the cover 25 is
Without protruding, and the car 25 is curved upward
Since it is formed, it is difficult for the foot to be caught and the getting on and off the machine 3 can be performed safely.

[0014]

As described above, according to the present invention, the cover can be formed by covering only one side of the opening without sacrificing the operation area of the pedal, even if the body is compactly constructed. area to be small, during operation or seedling supply etc., or when getting on and off of the aircraft, without such legs enters the said opening, it depresses the pedal arm
Nor. Also, the cover extends along the slope of the pedal arm.
Because it is formed in an upwardly curved shape,
It is difficult and safety is further improved. Further, in the case of the left and right brake pedals in which a plurality of pedals stand up from the same opening, even if a foot rides on the adjacent pedal arm arranged in close proximity and the pedals are accidentally operated simultaneously, the cover There it is possible to prevent erroneous operation such as depressing the next pedal arm by mistake since the guard of the pedal arm, the pedal
The cover 25 is just stepped on when the steps 16 and 17 are operated.
It also serves as a cradle supporting the heel part of the side feet,
7, the operability is improved.
