THROTTLE CABLE ADJUSTMENT:
Correct
cable adjustment engages choke mechanism
on engine when throttle control on handle dash
is set all the way to right (‘Start’). To adjust,
loosen cable clip screw on engine, then slide
cable out approximately 1/8-1/4”. Retighten
screw, recheck, readjust as needed.
•
SAFETY SWITCH ROD ADJUSTMENT:
Loosen set screws on safety handles, raise each handle
approximately 1/4 – 1/2”, retighten one set screw, check for uniform contact between both handles with
handle assembly, retighten other set screw. Note: tighten set screws to 150 in. lbs.
•
STEERING ADJUSTMENT:
Check tire pressure – 20psi rear, 50psi front. If correct, see Brake
adjustment.
•
CUTTING BLADE HEIGHT ADJUSTMENT:
Each blade assembly contains six 1/4” blade spacers: three on
the bottom of the spindle assembly between blade and spindle, and three above between the spindle and
the blade bolt jam nut. Combined with the axle adjustment set at the factory, cutting height is set at
approximately 2-1/2”. Cutting blade height can be adjusted to between 1-3/4” and 3-1/4” by removing jam
nut and repositioning washers. Retighten jam nut to 60 ft. lbs.
•
AXLE HEIGHT ADJUSTMENT:
Your unit
comes with a unique rapid-adjust axle
assembly for additional cutting height
adjustment. Initial factory adjustment sets the
bottom rear edge of the blade deck
approximately 1-1/2” above the mowing
surface; however, it can be adjusted to 5” in
height. To adjust, first position a jack under the
rear of engine deck and raise. Loosen the two
3/8” bolts on either side of axle assembly (held
in place by press-fit nuts, so only one wrench is
needed). Drop or raise axle assembly to
provide desired height, then retighten bolts.
Remove jack and adjust the front casters by
repositioning the spacers.
Note:
Remember
that factory-set cutting blade height is 1” above
bottom edge of blade deck.
Note:
It is
recommended that the front height of the
mower be adjusted to 1/4” lower than the rear,
to allow for the blades to cut with the leading
edge and thus assure a finer cut.
