A manual control mechanism for a lift unit having a lift arm and a hydraulic cylinder for lifting the lift arm up and down. The mechanism includes a control valve configured as a three-position switchover valve for selectively providing lowering, neutral and elevating conditions according to a spool position for controlling movement of the hydraulic cylinder, a lift lever for manually operating the control valve and an operational path for guiding operational displacement of the lift lever. The operational path includes an inching operational path for operating the hydraulic cylinder at a creeping speed by slightly opening a port of the control valve and a main operational path for operating the control valve over an entire stroke range thereof. An operational feel when the lift lever is operationally displaced along the inching operational path is different from an operational feel when the lift lever is operationally displaced along the main operational path.

Manual control mechanism for lift unit

A tractor having an engine disposed in a front position, a transmission case disposed in a rear position, and a main frame for interconnecting the engine and transmission case. Reinforcing frames are attached to opposite side surfaces of the main frame. The reinforcing frames are shaped to accommodate a mid-mount mower.

Reinforcing frame for a working vehicle

A connection structure for connecting a loader bucket, through a mounting bracket pivotable by extension and contraction of a cylinder, to a forward end of a boom assembly vertically movably attached to a working vehicle. The mounting bracket includes a pivot element and an engaging member. The mounting bracket is pivoted by the cylinder with the pivot element anchored to a hook provided on the bucket, to engage the engaging member with an engageable member provided on the bucket. Upon completion of this engagement, a lock mechanism is operable to cause a locking pin to extend through and latch the engaging member and engageable member.
