Your MF 1200 Garden Tractor re¬
quires a Rear PTO Kit, Implement
Lift Hitch Kit, in order to attach
the MF 3650 Tiller. A Tractor
speed Reduction Kit and Lift Help¬

these kits. If these kits are al¬
ready installed, remove the "C"
frame and its lift links.
Fig. 1. If tractor is equipped
with Rear PTO Shield, Fig. 1,
remove this also as the Tiller
has its own PTO shield permanently
attached to the frame.
Remove four (4) existing bolts
from rear PTO belt cover, but do
not remove cover itself, Fig. 2.
Note that lift hitch mounting
brackets remain on tractor.

position about 1 or 2 feet in
front of Tiller, place in neutral
and shut off engine.
3. B l o c k up front of Tiller un¬
til lower hitch frame is about
the same height as lower hole on
tractor hitch mounting brackets.
4. B ac k tractor by hand until
lower pin holes are lined up,
install short "L" pins and secure
with hairpins, Fig. 6. Never
use middle or upper holes as
lower hitch frame will interfere
with drive pulley in transport
position.
5. P l a c e drive belt inside upper
Tiller hitch frame and attach

drive components resulting in short¬
er life. Correct belt tension
allows belt to slip if rocks 3 roots
or other solid objects are encoun¬
tered.

LIFT LINK ADJUSTMENT
Correct lift link adjustment is
necessary to obtain maximum trans¬
port height of the Tiller and ad¬
equate working depth or ground
pentration. This adjustment is
considered correct when the stop
bar (lower right-hand side of
lower hitch frame) contacts the
lower right-hand attaching bracket
with the tractor lift lever in full
rearward position. To accomplish
this proceed as follows.
1. R a i s e Tiller until stop bar
contacts mounting bracket and block
up securely, Fig. 11.
A CAUTION: Tractor lift lever
will require high hand actu¬
ating force with Lift Helper
Spring hooked up. Operate only
from tractor seat and keep
others away from Tiller while
doing so.
2. Release all pressure on lift
link by moving tractor lift lever
forward.
3. Loosen 2 bolts on Tiller lift
link, Fig. 12, and then move trac¬
tor lift lever fully to rearward
position.
4. Holding lift link up, tap down
ears on upper end of lift link and
tighten the two retaining bolts.

OPERATION
Before operating Tiller, always
check area to be worked. Do not
run over large stones, pipes or
other heavy obstructions which
could damage Tiller.
A CAUTION: Never adjust or work
on Tiller with tractor engine
running. Although Tiller will
not normally throw heavy ob¬
jects , keep persons and pets
from directly behind when it
is in operation. Always make
certain rear shield is lowered
when Tiller is being operated
in rocky conditions.
OPERATING TILLER
NOTE: Do not try to operate Tiller
in long grass or high weeds. Cut
and remove this material before
tilling. Failure to do this will
usually result in wrapping of ma¬
terial on tine shaft reducing
efficiency of tines.
1. Raise or lower Tiller with trac¬
tor lift hitch lever or with power
lift control, if so equipped.
2. To engage Tiller, move tractor
rear PTO lever to the "ON" position.
3. Depress tractor neutral return
brake pedal, place gear shift lever
in 1st gear.
4. Advance throttle to "FAST" posi¬
tion and lower Tiller slowly to
engage soil.
5. Release neutral return brake
pedal slowly and fully. Recommended
forward speed for tilling is 0.5
mph and 1.0 mph for cultivating.
(Tractor speed reduction kit recom¬
mended. )
6. Always raise Tiller when turning
or backing tractor.
Fig. 13 - LEVELER BLADE
1. Leveler Blade Lowered
7. Lower leveler blade when tilling
to produce a finer or smoother
seedbed, Fig. 13. For coarse bed
or when cultivating, move leveler
blade all the way up, Fig. 14.
8. If Tiller should encounter a
heavy obstruction, stop tractor
immediately and disengage Tiller
drive. Should a large accumulation
of heavy vines or weeds wrap around
tines or shaft, turn off tractor
engine and remove this material
before proceeding.
9. If tractor is to be stopped for
any length of time with Tiller in
working position, quickly disengage
