has an upstanding integral sleeve 41 at its upper
.45 end engaging'in aroller bearing 48 mounted in
the“ upper end of ‘the upper cap 26. The sleeve
extends‘ through a guide collar 49 suitably fas
tened" on the cap 26 in the hood 34; the shaft
having a snug sliding ?t in‘said sleeve.
A suitable auger bit 50 is mounted on the lower
end of the shaft 35. 'Any bit suitable for the pur
pose may be employed'and a bit of the usual type
is‘ shown, which bit includes a tubular shaft 5|
having the shaft 35‘secured by a‘coupling52l-"in
thelupper end thereof. Byoperating the cou

pling, the bit may be taken off and either sharp
ened or replaced.
One of the particular features of the invention
resides in the manual adjustment and control
of the boring shaft. As is best shown in Fig. 2,
the upper end of the boring shaft 35 is provided
with a reduced upright shank 53 screw—threaded
at its upper end. A ?anged bushing 54 sur—
rounds the shank and rests upon a. collar 53’ at
the base of the shank. This collar is con?ned by 10
a nut 55 screwed onto the shank which in turn
is held in place by a jam nut 5-6, screwed onto the
upper end of said shank. A hanger ring 51 sur
rounds the bushing and roller bearings 51' are‘

brace bar 14 telescopes. The rear end of the
sleeve is attached to a universal joint 15 sup
ported by a bracket 15 secured to the side of the
tractor frame III’, at the medial portion thereof
(Figs. 1 and 6). The bar and sleeve are provided
with spaced holes 11 and 18 adapted to register
and receive a headed pin 19, whereby the bar and
sleeve are fastened in longitudinally adjusted po
sitions.
The forward end of the bar carries an ear 80
which is pivoted to a clamp 8| secured‘ about the
tube 18, intermediate the ends thereof. When
the gear housing 22 is adjusted vertically, the pin
19 is removed and the telescoping relation of the
brace member and the universal joint ‘(5, permit
