SIDE HITCH FRAME

ATTELAGE LATERAL PERPENDICULAIRE

English Abstract

ABSTRACT
In previous art, for raking simultaneously with baling,
the rake had to be ground supported on three caster wheels.
The applicant has a patent called "Hitch on the Right Side"
which pulls a rake ground supported on two fixed wheels at
the rear and on one swivel wheel, or on the hitch in front.
This invention is an improvement and simplification of
manufacture of said patent in which a hitch member is
pivotally secured to one arm mean, and a double action piston
make said hitch member to slide on the other arm mean or it
is restrained by pins on both side in a plurality of holes in
said other arms means. The new feature permits a variable
lateral rake to tractor distance for various windrow sizes
and type of baler. The arm means may be secured together by
a hinge joint and each said arm means may include two
telescopic sections for extension and contraction with lock
positions.

Claims

The embodiments of the invention in which an exclusive
property or privilege is claimed are defined as follows:
1- A side hitch frame to draw an implement as a rake
beside a tractor to produce a windrow which will be caught
by a baler attached to the same tractor and comprising:
a front arm mean and a rear arm mean connected to-
gether at their outer end
flat member means connected to the inner end of
said arm means
- attachment means mounted on the tractor's side to
connect flat member means by each a loose pin, only one
attachment mean 18 necessary if the tractor has a front
hitch
a hitch member mean pivotally secured to one said
arm mean and embracing the other arm mean
a swivel wheel assembly to support said arm means.
2-A side hitch frame as defined in claim 1 where said
hitch member mean sandwiching said arm means is made of two
parallel members secured to descending member and a hitch
plate also secured to descending member.
3-A side hitch frame as defined in claim 2 where the
arm mean on which the hitch member mean can slide include a
plurality of holes and said hitch member mean is restrained
by a pin on each side fitted in said holes in said arm mean
giving said hitch plate a plurality of predetermined lateral
position.
4- A side hitch frame as defined in claim 2 where one
said arm include a bracket secured to it to receive a double
action piston to produce the pivotal movement of said hitch

member mean giving at will an infinity of different lateral
position of said hitch plate.
5- A side hitch frame as defined in claim 1 where the
connection of the arm means together is a hinged joint permit-
ting angular displacement of arm means for compact storage easy
handling and quick coupling to the tractor.
6- A side hitch frame as defined in claim 5 where the
swivel wheel assembly is mounted in the said hinged joint.
7- A side hitch frame as defined in claim 5 where the
arm means include telescopic sections for extension and/ or
contraction with lock positions, the contraction will be used
for still more compact storage.

SPECIFICATIONS
Thi~ invention relates to a hitch on the side of a
tractor to pull an implement as a rake.
It is known to hitch the rake(s) behind the tractor in
dlfferent ways, but the baler cannot be hitched to the ~ame
tractor at the same time. So the tractor has to go through
the field twice, re more soil co~paction and more fuel and
time consumlng. If the wind is strong in the interval between
raking and baling, there will be windrow dlsturbances result-
ing in a losa to the farmer. If the rain comes before baling
i8 finlshed, the windrows left will have to be done again.
These problems can be overcome by a hitch on the side
of a tractor to pull a rake leaving the back hitch for the
baler, raklng and ballng will be done at the ~ame time,
propulsion coming from the same tractor.
In the drawings which illustrate the preferred embodiment
of the invention.
Figure 1 is a plan view of the embodiment with part
of the tractor;
Figure 2 is a view taken along line 2-2 of Figure l
looking in the direction of the arrows.
Figure 3 ls an enlarged sectional view taken along
line 3-3 of f~,igure l looking in the direction of the arrows.
Referrine to Figure 1, ~ront arm 10 inside section
may be bent to pass ahead of tractor's front wheel 12.
Referring to Figures 1 and 2, flat member 13 is
secured by means of weld or the like to the inner end of front
arm 10. The flat member 13 would be ~ointed to the tractorls
front hitch 14 or to an attachment similar to the attachment 16
at the side towards the front of the tractor'~ chassis by means
of a

1~74863 page 2
loose vertical pin 15 pro~ected through suitable holes in
~lat member 13 and tractor's ~ront hitch 14 or the said
attachment, allowing the outer end of front arm 10 to follow
the contour of the ground.
Attachment 16 is secured by means Or bolts or the
llke to the tractor's chassis 18 on the side. Flat member
19 secured by means o~ weld or the like to the inner end o~
rear arm 11, is ~ointed to the attachment 16 by mean o~ a
loose vertlcal pin 20, allowing the outer end of rear arm 11
the ~ame rreedom as outer end of ~ront arm 10.
~ ront arm 10 and rear arm 11 may be made o~ two
piece~ of tubing each telescope ~or extension or contraction
with lock positlons for lenght ad~ustment.
Generally horlzontal parallel members 26 are secured
to descendin6 member 28 by means o~ wel1or the like. Hitch
plate 29 i8 secured to descending member 28 by means of weld
or the like. Hitch plate 29 bears hole 30 where the
implement as a rake, should be hitched. Parallel member 26
descendlng member 28 and hitch plate 29 are generally
described as hitch member 31.
Parallel members 26 are pivolally secured to front
arm 10 by means of pin 25 in suitable holes in parallel
members 26 and in front arm 10. Parallel members 26 are
sandwiching front arm 10 and rear arm llo
The pivoting movement of hitch member 31 may be
produced by double action piston 24, Bracket 22 is secured
by means of weld^or the like to front arm 10. The base Or
double action piston 24 is secured to brac~et 22 by pin 23
~itted in suitable hole~; the piston rod is secured to
parallel members 26 by pin 27 fitted in suitable holes.

The pivoting movement of hitch member 31 will place the rake
in different lateral distance to the tractor while travellin~;
a usefull feature for some type of baler who have to receive
the windrow in different lateral position to produce nice
bales.
Instead of double action piston 24 hitch member 31
could be restrained by means of a pin on each side, fitted in
a plurality of suitable holes in rear arm llo Different pre-
determlned tractor to hitch plate 29 lateral distance allow
a convenient hitch for a rake of different desi~n provided
rake is ground supported on two wheels.
Referring to Figures 1, 2 and 3, front arm 10 and rear
arm 11 may be secured together towards thelr outer end by a
hlnged ~oint 32 permitting angular displacement of arms 10
and 11 for easier quick coupling to the tractor at any two
points,or storage or handlin~.
For this purpo~e a sleeve 21 is secured by means of weld
or the like to the end of rear arm 11. Two plates 33 encircle
each end of the sleeve 21 and are secured to front arm 10 by
means of bolts 40 or the likeO
Swivel wheel assembly 36 has as upright wheel 37 rotata~y
supported on an axle 38. Secured to axle 38 upright standard
39 pro~ects through the sleeve 21. Retaining members 34, as
collars, secured to standard 39 maintains standard 39 assembled
with the hinged ~olnt 32.
