The present invention relates to a control

speci?cally, it relates to'?uid-pressure means for

nected with the crank axle 39 by a link 51. The
response to ?uid under pressure supplied to the
cylinder by the pump [5 through ports |8 and
IS controlled by a valve 20. The valve 20 is under
control of a hand lever 2| pivoted at 22 on the
cylinder 45 is connected at 58 to a bracket 59
secured to a structure 60 at the rear of the trac
tractor and connected With the valve by a rod 23 Gl tor |0. A rodl6l -connected with the piston 46
extends from the cylinder 45 and is connected
extending from the valve. There are stop shoul
at 62 to a lever 63 pivoted at 64 on the tractor
ders 24l andy 25 jon the rod 23. The lever 2| is held
in a central neutral position, as> shown in Figure
l, by'the action of springs 26 and 21 mounted ,
upon a member 28 extending through the lever .1,0
2I. When the lever 2| is in the central neutral
position of Figure l, the valve 20 is inV a corre
sponding neutral position in which the ports |8
and |9 are closed, and fluid within the 'cylinder
l6 on both sides of the piston 11 is looked in the 15
cylinder. Figure 3 shows the piston |1 to be at
the right end of the cylinder 164.V When-the piston
is to be moved to the other end, the hand lever
2l is actuated to move the valve 20, leaving' the
ports H3V and I9uncov'ered so that ?uid under
presšiífe'maygbe admitted'to the port |8 and' al
low'ed to 'escape through the port l9.
I'jjExtending from the piston" is a rod 29 hav
cylinder 4.5, the conduit 50, and the cylinder 41.
By vvirïtiiéïo'f the connection between the piston
|1 in the cylinder [6 and the piston 46 in the
cylinder' '45 movement of the piston l1 in the cyl
inde'r l 6 under 'thev action of ?uid under pressure
supplied toV the cylinder |6 by the pump |5 is
transmittedto the piston 46. Thus, as the piston
l1 »is moved from the extreme right position of
Figure 3,Å it serves to move the piston 46 from the
20 extreme left position of Figure 2.V As the piston
46.moves from this position, the ?uid 66 isfforced
from' the' cylinder 45 through thejhose 50 into
the cylinder 41, and the piston 48 'is'mOved to
theÅ rightragainst the actionl of the spring~49,
Thus, thecrank axles 39, 40,>and 4| are caused
.ingï'ari'ienlarged portion 30 vat its end from which

opening'throughwhich the rod 23 extends. The

It will be apparent from the foregoing descrip
tion that novel means have been devised for con
trolling either an implement directly connected
to a tractor or one pulled therebehind in trailing
relation. This means utilizes in combination a
hydraulic ?uid system complete in itself with a
mechanical member forming part of a tractor
power lift mechanism. It enables an cperator to
