By the construction of the frame, the section 6 containing the motor, driving and turning wheel, and connections can be attached to frame sections 1 carrying differ- .ent implements. Y

The frame element 2 is provided with a wheel as a caster wheel '9 at its outer end.

The implement supported by the frame includes a movable member which is actuated by the motor, and the implement here shown is a mower including a finger bar 10 and a reciprocating knife 11-, the mower being arranged in front of the frame element 2 and caster wheel and atone: side of the beam 1 and the path of thewheels 5. and 7.-

The mower is provided with inner and outer swath boards 10 and 10 which deflect 1 the grassor grain inwardly so that it will not be run over by the caster wheel 9-01- the driving an turning wheel 7.

v The steering wheel 1s arranged to travel. in advance of the finger bar and entirely at one side of the standing grass or grain, and

in the path cleared by the outer swath board during the previous trip of the machine across the field as illustrated in dotted lines, Fig.1, and the driving and turning wheel 7 is also arranged to travel in said path cleared by. the outer swath board .during the previous trip of the machine. Hence-the steering wheel and the driving and turning wheel travel in the same path.

The steering'wheel 5 is operated'b a rotatable shaft 12 suitably supported ythe frame 1 andhavinga worm 13 at one end meshingwitha worm gear 14 on the upright spindle 15: ofthe forks 4, the shaft 12 hav-. mg a handwheel 16 at its other end located" within reachof the seat 17 which is sup- ;ported on the frame section 6.

. Either endfofthe finger bar or mower or both ends thereof may be raised in any suitable manner by any suitable means, to avoid obstructions in the "field jo'r to be carried I also operates the other to raise both ends of thefing bar.

The ;shoe 21 is supported ,by a suitable swinging frame and the parts 29 and 30 swing during theraising of the finger bar about an axis located near the axis of the shaft 2.

The rear end of the swinging frame 30 is adjustable vertically to tilt or direct the edge of the finger bar and knife upwardly or downwardly more or less into different angular relations relatively to the ground, and this adjustment is effected by a lever 30 mounted on the frame 1 within reach of the seat and having an arm 30",-Fig. 5, which is connected by a link 30 to the slotted bearing Q30 at the rear'end of the swinging frame 30. The slotted bearing 30 receives a box 30 mounted on the pivot 30 on which the The lever 30* is held in its adjusted position by a pawl operated by a grip lever on the lever 30 and cooperating with a rack on the beam 1.

The levers 18 and 19 may be connected together in any suitable manner, one way of efiectin this result being shown in Fig. 9,

the lever" 19 is shown with a laterally'extending lug 31 extending in the rear -;of; t he lever 18, the lever '19 being movable laterally against the influence of its own resiliency to disengage the lug 31 from the lever- 18.- Suitable lifting springs 32 and33 are connected to the frame and, respectively, to the. levers 18 and 19.'

351 is an axle upon which the driving and corner-turningwheel 7 is mounted, this axle beingconne'cted to the frame by an upright pivotal connection as the upright bearing 35 at the'inner end of the axle, and a spindle or shaft 36 extending throu h the bearings 37 on'theyp'ortion 6 of the rame and through thebearing-35, see Figs. 4,5 and 8. w

The wheel 7 is movable about its upright axis" from its normal position into and out ofan angular position relatively to the normal line of travel of the machine, as indicatedin' dotted lines, Figs. 1, 4 and 5.

' The power-transmitting connections between the motor 8 andthe driving and turnin wheel 7 comprises a ear 39 arranged concentric with the axis of the wheel 7 and fixedthereto, a gear 10 mounted on the spindle 36'. and having a gear ring 41 meshmg'with the gear 39, and a gear ring 42 meshing with-a gear 43 mounted-on one end of afshaft Mjournaled in a bearing 45 in the frame section 6 and extending lengthwise of the frame,'a gear 46, mounted on the front end of said shaft 4% and meshing with a In the normaljoperation. of the, machine,; the motion is transmitted from the motor shaft 52 to the shaft 51, gear-', gears 48, 47, beveled gear 46", shaft 4, gears 46, 43, "40 and 39. i
