    摘要： An easily attachable and detachable tool-mounting apparatus for mounting a plurality of earth-working tools to a tractor provided with a hydraulically-actuated lift apparatus. The tool-connecting apparatus, which comprises outwardly extending booms to which are connected tool-mounting bars parallel thereto, is carried by the lift apparatus. To the forward portion of the lift apparatus is connected another tool-mounting bar. The tool-connecting apparatus is borne by the tractor solely through the hydraulically-actuated lift apparatus, whereby the toolconnecting apparatus may be easily raised and lowered, and thus may be easily attached and detached from the tractor. Means for swinging the outwardly extending booms out of the way of the tractor wheels are also provided.

    摘要： An automatic connection mechanism for a mid-mounted implement to a tractor is disclosed. The automatic connection mechanism includes a rear lift linkage pivotably attached to the tractor, that automatically and releasably engage the rear of the implement. The forward lift linkage is pivotably attached to the front of the implement, and automatically and releasably engages the forward end of the tractor. A PTO coupling member also is attached to the rear lift linkage to engage an opposing PTO coupling member on the implement.

    摘要： Differential length parallel lift arms have means at one end for attachment to a belly mounted tractor appliance. At their opposite ends the lift arms are adapted to be pivotally mounted on a common axis on a tractor under which the appliance is adapted to be located. Lift arm actuating means are connected to the lift arms for effecting substantially parallel lifting of the appliance by the arms. Means for effecting operation of the actuating means may be operated hydraulically or otherwise from the tractor seat.

    摘要： A vehicle mounted lift assembly having latch mechanisms for latching pivoted lift arms in an uplift position whereby an implement, particularly a powered rotary mower, connected to the lift arms can be automatically latched in an elevated position while other implements are being raised or lowered by the lift assembly. The latch mechanisms each include a pivotal and an axially translatable bolt having a non-circular end portion which is slidably received in a complementary non-circular opening when in an arm latching position. The bolt is manually movable to an unlatched position with the non-circular portion moved axially out of engagement with the non-circular opening, and with the bolt then being pivoted about its axis to preclude registration of the non-circular portion with the non-circular opening. A combination torsion-compression spring is prestressed to normally exert a compressive force tending to hold the bolt in latching position, and to normally exert a torsional force tending to pivot and maintain the bolt in its unlatched position. A cam face on the latch bolt automatically locks the associated lift arm in raised position in response to movement of the lift arm into its raised position only if the bolt has been pivoted to its latching position.

    摘要： A three-point mounting hitch for supporting an implement beneath a tractor and between the front and rear wheels thereof includes an upright rear frame member connectible with the tractor three-point hitch and a horizontal implement supporting frame member at the lower end of the rear frame member extended forwardly below the tractor. The implement is raised and lowered as a unit assembly with the three-point hitch into and out of an operating position. A belt drive mechanism on the hitch connects the tractor power take-off unit to the implement drive shaft.
