Cleaning The Engine Anddeck - MTD 660 Operator's Manual

• Behind the pivot bar, measure the distance
horizontally from the inside of the left rim to the
inside of the right rim. Note the distance.
• The measurement taken in front of the pivot bar
should be between 1/16" and 5/16" less than the
measurement taken behind the pivot bar. If it is not,
an adjustment is necessary. Proceed as follows.
• Locate the ferrule at the right end of the tie rod, just
to the rear of the right, front tire of tractor. See
Figure 21.
• Remove the cotter pin and flat washer which
secures the adjustment ferrule to the tractors right
axle.
• Two turns at a time, thread the adjustment ferrule
toward the right, front tire to lengthen the tie rod. Or,
thread the adjustment ferrule away from the right,
front tire to shorten the tie rod.
NOTE:
Lengthening the tie rod increases the tractor's
front tie toe-in. Shortening the tie rod decreases the
tractor's front tire toe-in.
Reinsert the adjustment ferrule and temporarily
secure it with the cotter pin removed earlier.
Make certain the steering wheel is in position for
straight-ahead travel before again taking
measurements. Continue to repeat the steps above
until a proper adjustment is achieved.
Secure the tie rod to the right axle with the flat
washer removed earlier and a replacement cotter
pin.
IMPORTANT: Do NOT reuse the original cotter pin once
it has been removed.
SECTION 7: MAINTAINENCE
WARNING: Before performing any
maintenance or repairs, place the PTO (blade
engage) lever in the BLADES STOP position,
move shift lever into neutral position, set
parking brake, stop engine and remove key to
prevent unintended starting.
Cleaning the Engine AndDeck
Any fuel or oil spilled on the machine should be wiped
off promptly. Do NOT allow debris to accumulate
around the cooling fins of the engine or on any other
part of the machine, especially the belts, pulleys and
other moving parts. Clean the underside of the deck
with a wisk broom, scraper or forced air after each
mowing.
IMPORTANT: The use of a pressure washer or garden
hose to clean your tractor is NOT recommended. It may
cause damage to electrical components, spindles,
pulleys, bearings or the engine. The use of water will
result in a shortened life of the tractor and reduce its
serviceability.
Engine
Refer to the Briggs & Stratton Operator/Owner
Manual (or Tecumseh engine's Owner's Manual)
