It should now be apparent from the above de
ed for quick attachment to the tractor brackets,

that there has been provided a bracket for the of the members to the tractor, and means for
‘support of the cultivator of the pendulum swing pivotally attaching the implement to the vertical
type adapted to be Aoperated by the steering
mechanism, that is of simple construction and
within the confines of the front end of the tractor
wherein the forward visibility of the operator is
50 not impaired. Also, a construction has been pro
vided which permits easy attachment or detach
ment' of the cultivator- to and from the tractor.
To detach the cultivator from the tractor, the
cultivator gangs are first lowered to the ground.
Ul $1 Front stand clamps ||4 are loosened to permit
lowering of the front stands | I5 to the ground
where they are again clamped to provide for a
iront end 'support of the cultivator. The offset
arms I1, 48 and 48’ are loosened fro-m the tool
60 bars to permit rearward rotation of the cultivator
tools and allow clearance forthe steering truck.
Next, the cutter-pin 66 of the push pipe connection
6| is removed and the push pipe is lifted out of
the holes 61 of the push pipe plate 68 and rested
65 on some sort of convenient support means.
The
nut |06 of the bolt |0| is now loosened, thereby
disconnecting the latch mechanism' 95 from the
axle spacer. The swinging arm connections 32
and 32’ on the vertical bracket supports are dis
70 connected and the tractor may now be backed
