You may "lock" both Throttle and Choke Controls (in the position you have selected) by
rotating the Handles 1/4 turn clockwise. They are "unlocked" by a 1/4 turn counter-
clockwise. NOTE: DO NOT "over-tighten" or "over-loosen" these Controls - a 1/4 turn
in either direction is sufficient.
D. With Engine running, keep your right hand on the #15L and #15R Control Handles and
hold them in the center or neutral position. Simultaneously, with left hand, release
#1K "Auxiliary Clutch" Handle from its position in front of (and retained by) #1R Clip
and in the direction of the Crankshaft's rotation, while simultaneously the lower #21
Power Shaft should rotate in the reverse direction.
While rotating the Crankshaft clockwise (as viewed from right side of Tractor) push
forward on the Left #15L Control Handle and notice how its "outside" #28 Idler Wheel will
engage and tighten the #34 Belt wrapped around the #29 Drive Pulley (on outside of left
#20 Shaft) and around the #31 Pulley (on left, next to #30 Pulley) on Upper #21 Power
Shaft. This action will cause the #29 Pulley to rotate clockwise and subsequently
(through the #20 Sprocket and Shaft and the #38 Roller Chain driving the #22 Rear Drive
Wheel) cause the Left Track to go forward.
Pulling rearward on the (above) #15L Handle will release the above's #28 Idlers' ten-
sion on the first #34 Belt and will then begin to apply tension with the second #28 Idler
Wheel onto the second #34 Belt wrapped around the second #29 Pulley (on inside of left
#20 Shaft) and its mating #31 Pulley (on left next to #30 Pulley) on Lower #21 Power
Shaft. This rearward position- of the #15L Handle will cause Track to reverse direction.
(Check #15R Control Handle for the same response as above.)
Now, with Engine still rotating, allow it to slowly move rearward (under #41 Spring
tension) and set the transmission (upper and lower #21 Power Shafts) in motion. Now,
firmly holding a Control Handle (#15R and #15L) in each hand, you can move the Tractor
forward by pushing forward on both #15 Handles; move rearward by pulling back on both
#15 Handles. Make a right turn by pushing forward on the #15L Control Handle while
simultaneously pulling rearward on the Right #15R Control Handle. (Left turns are accom-
plished by reversing above procedure.)
The Parking Brake is operated by rotating "clockwise" the Wing Nut mounted on top
front center of #4A Cover. By tightening this nut, you will draw the #47A Shaft against
the back side of all four #34 Clutch Belts - this will "lock-up" the #29 Pulleys and pro-
vide a very positive parking brake action. To release the brake, just rotate the Wing
Nut "counterclockwise" (only a few turns) until the #47A Shaft rises approximately 1/8"
above the #34 Belts - at this setting, take a center punch and up-set the thread directly
above the Wing Nut; this will keep the Wing Nut from ever coming off the 3/8-16 x 2-1/2
Carriage Bolt.
NOTE:
For maximum safety both Control Handles must be held by the operator either by a
single hand or with both hands while the transmission system is in motion. Therefore,
with the transmission in motion, the Control Handles should never be left unattended or
the natural action of the transmission will cause them to occasionally bounce back and
forth. If this condition takes place, it can be quickly stopped by disengaging the
transmission system with the Auxiliary Clutch Handle and then re-starting. If this con-
dition persists, repeat Step #24 in Assembly Instructions and move the respective #28
Idler assemblies forward in their respective slots to relieve this incorrectly adjusted
pressure on the #34 Belts. (NOTE: As you gain skill in the driving of your tractor,
and as your #34 Belts become shiny and broken in, you may want to move the #28 Idler
assemblies rearward for a quicker responding Tractor.)
