摘要： PROBLEM TO BE SOLVED: To provide a farm work machine of which maintenance works can be efficiently carried out. SOLUTION: This farm work machine 1 is equipped with a rotary 16 that plows and crushes the soil, a soil grader 30 that grades the crushed and plowed soil and a setting unit 31 that sets the soil grader 30. The setting unit 31 can be set to the soil-grading state at which the soil is graded by means of the grader 30 and to the soil-mulching state at which the soil is collected for mulching. The setting unit 31 can set the soil grader to the maintenance work state at which the grader 30 is almost all exposed toward the rear direction. The soil grader 30 is positioned higher than the rotary shaft of the rotary 16 in the maintenance work state.

摘要： PROBLEM TO BE SOLVED: To provide a foldable farm working machine wherein an extensible stone-crushing rotary can reliably be rotated by the rotation of a stone-crushing rotary in a state that working width of the stone-crushing rotary is enlarged with the extended stone-crushing rotary and a machine configuration for rotating the extended stone-crushing rotary is simple. SOLUTION: This farm working machine is assembled by installing a stone- crushing rotary 3 and a foldable, extensible working machine body 4 on the working machine body 2, by installing an extensible stone-crushing rotary 5 on the machine body 4 and by rotating the extended stone-crushing rotary 5 through the rotation of the rotary 3. The rotary 3 has coupling parts 25 and 97 protruding at ends of a rotary shaft 18 which have respective coupling sides 24 and 100 formed on the side in the rotational direction of the rotary 3. The extensible stone-crushing rotary 5 has parts 72 and 101 to be coupled which protrude at ends of an extensible rotary shaft 68. The parts 72 and 101 have respective sides 71 and 105 to be coupled onto the respective coupling sides 24 and 100 of the respective coupling parts 25 and 97.

摘要： PROBLEM TO BE SOLVED: To provide a rotor capable of continuously and uniformly leveling a nursery bed while pushing down a floating material into the soil by the cooperation of rotary tines formed into units, with pressing wheels concentrically rotating with the rotary tines while being pulled by a tractor. SOLUTION: This tractor pulling nursery bed-leveling rotor has a transmission case 7 suspended on the outer terminal part of a horizontal main driving shaft 6 driven by a driving part 2 connected with a power-output port 1 of a tractor, and pivotally supported so as to be rotated, on the upper part between right and left supporting side plates 9. A transmission system 8 for making a combination of two pressing frame wheels 13 concentrically rotating at the outside of a rotation shaft 10 having rotary tines 11 pivotally supported at the lower part between the right and left supporting side plates 9 to carry out the followed movement is installed in the transmission cases 7.

摘要： PURPOSE:To provide the subject apparatus capable of readily, surely and remotely performing a rotational operation of an extended grader, buffering an excessive tracting force or excessive vibration by elastic deformation of an elastic switch arm to prevent breakage of the drive unit of the elastic switch arm in the case the tracting force or the vibration is applied thereto due to a vertical movement of the extended grader and remarkably improved in workability. CONSTITUTION:This grader is equipped with a grader control unit 23 for rotating and folding an extended grader 17 toward the above of the second grader 14 and rotating and returning the extended grader 17 toward the direction of extension of the second grader 14. The grader control unit 23 involves a rotational shaft 32 held by brackets 25 attached to a machine frame 1 and an elastic switch arm 26 switchably rotated in the right and left directions by an output from the rotational shaft 32. The extended grader 17 is connected through an interlocking device 29 to the top part of the elastic switch arm 26 and each bracket 25 is equipped with a normal and reverse-rotation motor 31 for rotating the rotational shaft 32. This apparatus involves a switch 34 for remotely controlling the motor 31.

摘要： PROBLEM TO BE SOLVED: To provide a connecting shaft for an agricultural implement capable of calming down sound. SOLUTION: The connecting shaft 14 for the agricultural implement is designed to connect a first land grader 11 to a second land grader 12 and provided with a nearly cylindrical shaft body 41 freely inserted into openings 23 and 31. The connecting shaft 14 is fitted onto the outer peripheral side of the shaft body 41 and provided with a nearly cylindrical deformable body 42 having a smaller outside diameter than the inside diameter of peripheral edges 23b and 31b of the openings 23b and 31b in a state before deformation. The connecting shaft 14 is screwed onto the outer peripheral side of the shaft body 41 to deform the deformable body 42. The connecting shaft 14 has two nuts 45 for deforming the deformable body 42 and bringing the outer peripheral side of the deformable body 42 into close contact with the peripheral edges 23b and 31b of the openings 23b and 31b.

摘要： PROBLEM TO BE SOLVED: To provide a fold agricultural working machine capable of grinding soil at a fixed operation width. SOLUTION: This fold agricultural working machine 1 is equipped with a working machine main body 2, extended working machine bodies 4 and 4, soil grinding rotaries 3 and extended soil grinding rotaries 5 disposed foldably at both end parts of the working machine main body 2, respectively. The extended soil grinding rotaries 5 are rotated by the revolution of the soil grinding rotaries 3. A state in which soil is ground by the soil grinding rotaries 3 and both the extended soil grinding rotaries 5 can be changed into a state in which soil is ground by the soil grinding rotaries 3 and either one of the extended soil grinding rotaries 5 or a state in which soil is ground only by the soil grinding rotaries 3.
