This invention relates to disk mounting, and
more particularly to.` the. mounting lof the disk
blades in the frames of a disk harrow or like im
plement, so that the disks are supported upon
5 tubular shafts journaled by an improved bearing
means upon a fixed shaft or axle secured to the
frame
structure.

It is an object of `this invention to provide an
improved form of mounting forA ground working
10 implements in a frame wherebythe ground work
ing implements are supportedfupon an improved
form of bearing means which is of simple ,con
struction and permits of the free running or rota
tionary shaft> 5. 'I‘he elements are maintained `
inV spaced relation upon the tubular shaft v3 4by
means of spacers 6, which spacers `6 are forrned
with complementary interfitting ends 'I and 8 be
tween which the elements 2 vare held. 'The ele-`
ments 2 are formed as illustrated with square
openings 9 intogwhich the square I0 of the end 8
,passesin order to cause the elements 2 to rotate
together with the tubular shaft 3. ,v The_square I0 .
fits into a corresponding square openingl I formed 10

utilized in disk harrow construction and have
illustrated the fittings for the shafts or bear

adjacent ends of the two shafts. The fittings
for the- outer ends of the shafts are the same as
those illustrated for the inner ends of the shafts.
In this modification of our invention above 10
described the disks 2b are locked to thespacer
6b ,so as to cause the disks 2b to rotate with the
shaft 3b in exactly the same manner as set forth
in the previous modification of our invention de
scribed except that in this case the inner ends 15
of the endlspacing collar 6b are made with an
annular recess IIb- to receive the locking pro
