摘要： PURPOSE:To enable separation of the front top mast from the back top mast and simple demounting of only the front top mast by mounting a pair of members and the front top mast on the back mounting parts with common fixing tools. CONSTITUTION:When the front top mast 5 is exchanged, fixing at two places is released with bolts 29 and 31 and a cylindrical unit 25 can be then taken from a gap between a pair of members 20 to the front to readily demount the front top mast 5. At this time, the back top mast 6 is supported by a bolt 23 and the top surface of a gear case 2 and present between a pair of left and right mounting parts 19. Thereby, a nearly constant posture is kept without unstable movement.

摘要： PURPOSE:To prevent spill of mud, etc., from a gap between a leveling cover and flap cover by forming a curved surface part with a transverse shaft as the center in the back end of the leveling cover and providing a curved surface part in a concentric form with the curved surface part on the front end side of the flap cover. CONSTITUTION:When the angle of a flap cover 12 is regulated, the flap cover is rotated on the transverse shaft 11 to engage an engaging part of a regulating lever with an optional engaging hole of a reinforcing rib. In the process, since curved surface parts 21 and 38 are concentric relatively to the transverse shaft 11, a gap between the leveling cover 9 and the flap cover 12 will not fluctuate by regulating the angle. Since the surface parts 21 and 38 are concentric and can be provided lengthwise in the peripheral direction with a small gap, spill of mud, etc., from the gap can be reduced.

摘要： PURPOSE:To facilitate the attaching and detaching operation of a tilling claw and shorten the time for the operation, by placing a checking part at the protruded side of a fixing shaft for fixing a tilling claw to a claw-fixing bracket of a claw shaft and using a fixing tool composed of an engaging part to engage a fixing shaft in such a manner as to release the engagement under a specific condition. CONSTITUTION:A base 37 of a tilling claw 22 is inserted between oppositely arranged walls 24, 25 of a claw-fixing bracket 21 fixed to a claw shaft 13. An attaching shaft 29 having a head part 30 is inserted and the protruded part of the shaft is provided with a checking part 31. An engaging part 45 engaging with the checking part to prevent the escape of the attaching shaft 29 is placed in such a manner as to release the engagement by moving the engaging part 45 toward the rotational direction A of the claw shaft 13 relative to the checking part 31. The fixing tool 41 having the above structure is constructed of an elastic plate curved in a manner to force the checking part toward the outside of the shaft direction with a spring force when the fixing tool 41 is engaged with the checking part 31 of the engaging part 45. A bent piece 47 engaging with the claw-fixing bracket 21 from the rotational direction A is attached to the rotational direction side A of the fixing tool 41 and an escape- checking part 48 detachably engaging with the claw-fixing bracket 21 from side opposite to the rotational direction A is attached to the fixing tool 42 at the opposite side of the rotational direction.
