Operating Tips
General Mowing Tips
• Clear the area of stic ks , stones , wire , branc hes , and
other debris that the blade could hit.
• A v oid striking solid objects with the blade . Nev er
deliberately mo w o v er any object.
• If the mo w er strik es an object or star ts to vibrate ,
immediately stop the engine , disconnect the wire from
the spark plug, and examine the mo w er for damag e .
• F or best perfor mance , install a new blade before the
cutting season begins .
• R e place the blade when necessar y with a T oro
re placement blade .
Cutting Grass
• Cut only about a third of the g rass blade at a time . Do
not cut belo w the 2-inc h (51 mm) setting unless the
g rass is sparse or it is late fall when g rass g ro wth begins
to slo w do wn. R efer to Adjusting the Cutting Height.
• W hen cutting g rass o v er 6 inc hes (15 cm) tall, mo w
at the highest cutting height setting and w alk slo w er;
then mo w ag ain at a lo w er setting for the best la wn
appearance . If the g rass is too long, the mo w er ma y
plug and cause the engine to stall.
• Mo w only dr y g rass or lea v es . W et g rass and lea v es tend
to clump on the yard and can cause the mo w er to plug
or the engine to stall.
W et g rass or lea v es can cause serious injur y if
y ou slip and contact the blade. Mo w onl y in dr y
conditions.
• Alter nate the mo wing direction. T his helps disperse the
clippings o v er the la wn for ev en fer tilization.
• If the finished la wn appearance is unsatisfactor y , tr y one
or more of the follo wing:
– R e place the blade or ha v e it shar pened.
– W alk at a slo w er pace while mo wing .
– Raise the cutting height on y our mo w er .
– Cut the g rass more frequently .
– Ov erlap cutting sw aths instead of cutting a full
sw ath with eac h pass .
– Set the cutting height on the front wheels one notc h
lo w er than the rear wheels . F or example , set the
front wheels at 2-1/4 inc hes (60 mm) and the rear
wheels at 2-3/4 inc hes (70 mm).
Cutting Leaves
• After cutting the la wn, ensure that half of the la wn
sho ws through the cut leaf co v er . Y ou ma y need to
mak e more than one pass o v er the lea v es .
• If there are more than 5 inc hes (13 cm) of lea v es on the
la wn, set the front cutting height one or tw o notc hes
higher than the rear cutting height.
• Slo w do wn y our mo wing speed if the mo w er does not
cut the lea v es finely enough.
