A reel mower having side reel mower units and a center reel mower unit connected to a vehicle body to be vertically movable between a lower position for a grass cutting operation and an upper position for a non-operational run. The side reel mower units and center reel mower unit have reels driven by reel drives under control of a control mechanism. A forcible stopping device is provided for forcibly stopping the reel drives of the reel mower units with priority over control of the reel drives by the control mechanism when the side reel mower units and center reel mower unit are all in the upper positions.

Reel mower

A mower unit includes a housing having a skirt portion extending toward the ground, and a covering wall surrounding a plurality of grass cutting blades to define spaces for mulching treatment. The covering wall includes peripheral wall members each curved along a locus of revolution of the blade and spaced from the skirt portion. The peripheral wall member includes a vertical portion descending toward the ground. The vertical portion and the skirt portion have lower ends thereof substantially at the same height over the ground. The blades are arranged transversely of the mower unit. The peripheral wall members are in the form of independent annular wall members provided for the blades, respectively. The annular wall members define spaces for mulching treatment substantially independent of one another. Alternatively, the peripheral wall members may be in the form of annular wall members corresponding to loci of revolution of the blades, respectively, and an adjacent pair of the annular wall members may have at least parts of peripheries overlapping each other. The parts of peripheries are cut so that the spaces of mulching treatment defined by the pair of annual wall members communicate with each other.

Mulching mower unit

A lawn mower comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and grass collecting containers each defining a top opening for receiving grass clippings sent through the discharge duct. The containers are supported by an E-shaped frame connected to, and retained by pins in, open rear ends of right and left pipe frames extending rearwardly and then upwardly from a mower body. The E-shaped frame engages the open rear ends of the pipe frames to interconnect the rear ends with a selected spacing therebetween.

Lawn mower

A lawn mower comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and a grass collecting container defining a top opening for receiving grass clippings sent through the discharge duct. The grass collecting container includes a mouthpiece extending along peripheries of the top opening to rest on a U-shaped support frame mounted at a rear end of the mower. The mouthpiece is connected to the support frame by a projection and bore engagement. The support frame includes a holder defining an upwardly opening recess, and the container has a cover defining a downwardly opening recess at a position opposed to the holder. The two recesses define an opening for receiving a rear end of the grass discharge duct. The grass discharge duct includes an annular engagement portion extending peripherally of the rear end thereof for engagement with inner edges of the two recesses.

A tractor transmission structure including a first and a second gear transmissions operatively connected in series, each gear transmission providing two speeds. The invention provides a single change-speed lever to operate the two gear transmissions. The change-speed lever is guided along a U-shaped opening to obtain three speeds from the gear transmissions, a low speed, an intermediate speed and a high speed.

Tractor transmission structure

A work vehicle comprising a stepless hydraulic speed change apparatus, a radiator for cooling hydraulic fluid for the said apparatus, a hydraulic cylinder for actuating a work implement, and a hydraulic pump provided with a suction portion. A return flow path is provided for supplying hydraulic fluid from the radiator to the suction portion of the oil pump.

Work vehicle

A work vehicle having an oil cooling path through which a working oil within the transmission housing for the hydraulically driven transmission means is circulated to the transmission case through the cooler. There is disposed a bypass adapted to return the working oil directly to the transmission case from said transmission housing without passing through the cooler when the pressure in said transmission housing exceeds a predetermined value.

A structure for attaching a hitch to a tractor for detachably connecting a trailing working device to the tractor. A rod for pivotably supporting a pair of opposed lower links for connecting a ground working implement to the tractor pivotally movably up and down is supported by and extends transversely through a transmission case portion. The hitch is supported on the rod.

Structure for attaching hitch to tractor

A device for tightening an endless element which is trained over driving members and which is accommodated in a drive transmission housing. A regulation member is provided outside the housing for easy adjustment of the tautness or tension of the endless element.
