Abstract: A rear discharge mower unit (50) with a mower housing (55) defining grass clippings flow paths for directing grass clippings rearward. The mower unit includes a power transmission mechanism for rotating a center blade (58) and a second side blade (60) in one direction and a first side blade (59) in the other direction, a center baffle (63) extending around a rotational axis of the center blade and defining a center flow path (69a) for feeding grass clippings to a grass clippings outlet (66), a first side baffle (64) extending around a rotational axis of the first side blade (59) and defining a first side flow path (69b) for feeding grass clippings to the grass clippings outlet (66), and a second side baffle (65) extending around a rotational axis of the second side blade (60) and defining a second side flow path (69c) for feeding grass clippings to the center flow path (69a).

Abstract: A working vehicle with power steering, having a substantially closed accommodating space defined by an engine hood and a control panel, an engine disposed in the accommodating space and a steering shaft disposed in the control panel. A cooling fan produces cooling air flows moving toward the engine from an air intake formed in the control panel. A power steering apparatus for supplying steering assist power to the steering shaft, and a control unit for controlling the power steering apparatus, are arranged in the accommodating space to be exposed to the cooling air flows.

Abstract: A method and a device for the analysis of 5-hydroxyindoles or catecholamines with high sensitivity. New chemiluminescence labeling agents, 6-aminomethylphthalhydrazide or 1,2-bis(phthalhydrazino)ethylenediamine, are reacted with 5-hydroxyindoles or catecholamines to form their stable derivatives. The derivatives emit strong luminescence in the presence of an oxidizing agent. In the chemiluminescence detection method, there is extremely low background noise and thus the method enables analysis with high sensitivity.
