Step 6: Check Level Of Transmission Gear Oil; Step 8: Check Hardware For Tightness - Troy-Bilt 644H-Bronco Operator's Manual

3. Use a cable tie (EE, Fig. 2-9) to fasten
the reverse clutch cable to the left side
handlebar.
4. Test the function of the reverse clutch
cable by pulling the knob out and
releasing it. The knob should return to its
neutral position (resting against bracket)
when it is released. If it doesn't, contact
your local dealer or the factory for
technical assistance.

STEP 6: Check Level of
Transmission Gear Oil
The transmission was filled with gear oil
at the factory. However, you should check
the gear oil level to make certain it is
correct.
IMPORTANT: Do not operate the tiller if
the gear oil level is low. Doing so will
result in severe damage to the transmis-
sion components.
1. Put the tiller on level ground. Pull the
Depth Regulator Lever (FF, Fig. 2-10)
back and then adjust it up or down to the
notch that makes the tiller level.
2. Remove the oil fill plug (GG, Fig. 2-11)
from the transmission housing and look
into the oil fill hole. You will see the main
drive shaft on one side of the hole.
3. The gear oil level is correct if the gear
oil is approximately halfway up the side of
the drive shaft.
4. If the gear oil level is low, add gear oil
by referring to "A. To Check the Transmis-
sion Gear Oil Level" in Section 5.
STEP 7: Add Motor Oil to Engine
The tiller is shipped without oil in the
engine.
CC
IMPORTANT: Do not start the engine
without first adding motor oil. Severe
engine damage will result if the engine is
run without oil.
1. Refer to the Engine Owner's Manual
(supplied with tiller) for engine oil specifi-
cations and capacities.
2. With the tiller on level ground, pull the
Depth Regulator Lever (FF, Fig. 2-10)
back and then slide it up or down as
necessary until the engine is level.
3. Add motor oil as described in the
Engine Owner's Manual.
4. Move the Depth Regulator Lever all the
way down until the highest notch is
engaged. This places the tines in the
"travel" position.

STEP 8: Check Hardware for
Tightness
Check all nuts and screws for tightness.
STEP 9: Check Air Pressure in
Tires)
Use a tire pressure gauge to check the air
pressure in both tires. Deflate or inflate
both tires equally to 15-to-20 PSI
(pounds per square inch). Be sure that
both tires are inflated equally or the unit
will pull to one side.
IMPORTANT: This completes the
assembly steps. Before operating your
tiller, make sure you read the following
Sections in this Manual, as well as the
separate Engine Owner's Manual:
• Section 1: "Safety"
• Section 3: "Features and Controls"
• Section 4: "Operation"
