Abstract: A riding-type mowing apparatus includes: a lower limit adjustment lever provided at a position where a user reaches the position by extending an arm of the user; a lever connection bar coupled to a lower portion of the lower limit adjustment lever and extending in a linear shape; a lower limit adjustment step rotating together with the lever connection bar and adjusting a lift-down height of the mower unit; a first front deck link coupled to a front upper surface of the mower unit; a second front deck link coupled to the first front deck link and the body frame; a first rear deck link coupled to a rear upper surface of the mower unit; a second rear deck link coupled to the first rear deck link and the body frame; and a protruding latch part making contact with a lower surface of the lower limit adjustment step.

Abstract: According to an embodiment, a riding-type mowing apparatus, in which a mower unit is disposed below a body frame to mow grass through a blade mounted in the mower unit and a driver seat is provided on the body frame, includes: a steering lever provided on both sides of the driver seat to operate traveling of the riding-type mowing apparatus; a brake pedal provided on a bottom frame disposed in front of the body frame to brake the riding-type mowing apparatus; and a lift-down pedal and a lift-up pedal disposed on both sides of the brake pedal to lift-down and lift-up the mower unit, respectively.

Abstract: A mowing apparatus includes: a deck unit mounted below a body frame and including a blade for mowing; a first deck link coupled to an upper surface of the deck unit; a rotary shaft rotatably provided below the body frame; a second deck link rotated together with the rotary shaft and disposed on the first deck link; a link arm coupling bolt coupled to an upper portion of the first deck link while passing through the second deck link; and a deck height adjustment part including a height adjustment bolt for adjusting a height of the link arm coupling bolt.

Abstract: A tomography apparatus includes an image processor configured to obtain a first image, which is a partial image of an object, by using data obtained from a first angle section corresponding to a first point, and to obtain a second image, which is a partial image of the object, by using data obtained from a second angle section corresponding to a second point subsequent to the first point; and a controller configured to obtain first information representing a brightness change, to obtain second information representing a rate of change in a Hounsfield unit (HU) value between the first point and the second point based on the first information, and to determine a tomography start point of the object based on the second information.
