DIFFERENTIAL LOCKING OPERATION UNIT STRUCTURE FOR RIDING TYPE RICE-PLANTING MACHINE

摘要

PROBLEM TO BE SOLVED: To surely prevent a power transmission system from being damaged, to simplify a damage preventing structure of the transmission system and to reduce a manufacturing cost.;SOLUTION: The riding type rice-planting machine comprises a differential locking unit provided in a differential locking device, a differential locking unit operating unit cooperatively coupled to the differential locking unit via a differential locking unit interlocking mechanism. In this machine, the differential locking unit operating unit has an operating element, a working element for operating the differential locking unit interlocking mechanism cooperatively to the operation of the operating element, and an elastic element interposed between the working element and the operating element and interlocks the working element with the operating element via the elastic element.;COPYRIGHT: (C)2003,JPO
