OPERATION
Read  the Safety sectio\f a\fd followi\f\ag pages, if you 
are u\ffamiliar with th\ae machi\fe.
Training
Due to u\fique steeri\fg\a capabilities, zero tur\f mowers 
are far more ma\feuverable tha\f t\aypical ridi\fg mower\as.
This sectio\f should\a be reviewed i\f its e\fti\arety prior to 
attempti\fg to move \athe mower u\fder its\a ow\f power. 
Whe\f first operati\fg \athe mower or u\ftil \abecomi\fg 
comfortable with co\ftrols, use a reduced throttle 
speed a\fd reduced grou\fd speed. DO NOT m\aove 
co\ftrol levers to the f\aurthest forward or reverse 
positio\fs duri\fg i\fi\atial operatio\f.
First time users sh\aould become familiar\a with the 
mower’s moveme\ft o\f\a a hard surface, such as 
co\fcrete or blacktop PRI\aOR to attempti\fg to\a operate 
o\f turf. U\ftil the operat\aor becomes comfortable with 
the mower co\ftrols a\fd zero tur\fi\fg capability, overly 
aggressive ma\feuvers may\a damage turf.
Steering
To move forward and\g \fackward
The directio\f a\fd speed of \athe mower’s moveme\a\fts 
are effected by the move\ame\ft of the co\ftrol lever(s) 
o\f each side of mow\aer. The left co\ftrol lever co\ftrols 
the left wheel. Th\ae right co\ftrol lever co\ftrols the right 
wheel.
First time users sh\aould push the mower\a (see Moving 
Machine By Hand i\f the Operation sectio\f) to a\f 
ope\f, flat area without other pe\aople, vehicles or 
obstacles \fearby. To move the u\fit u\fde\ar its ow\f 
power, the operator must \asit i\f the seat a\fd \astart 
the e\fgi\fe (see Before Starting i\f the Operation 
sectio\f). Adjust th\ae e\fgi\fe speed to i\adle, dise\fgage 
the parki\fg brake bu\at do \fot e\fgage the \ablades at 
this time. Rotate c\ao\ftrol levers i\fward. As lo\fg as 
the co\ftrol levers have \fot \abee\f moved forward or 
backwards, the mower will \a\fot move.
\blowly move both co\a\ftrol levers forward slightly. This 
will allow mower to\a start movi\fg forward i\f a straight 
li\fe. Pull the co\ftr\aol levers back to t\ahe \feutral positio\f \a
a\fd the mower should\a stop movi\fg.
Pull back slightly \ao\f co\ftrol levers, allowi\fg \athe mower 
to move backwards. Push the co\ftrol levers forward to 
the \feutral positio\f\a a\fd mower should st\aop movi\fg.
To turn to the right
While movi\fg i\f a fo\arward directio\f, pull the rig\aht lever 
back towards the \feutral posit\aio\f while mai\ftai\fi\fg\a 
the positio\f of the\a left lever, this will slow th\ae rotatio\f of 
the right wheel a\fd\a cause the machi\fe t\ao tur\f i\f that 
directio\f.
To turn to the left
While movi\fg i\f a fo\arward directio\f pull the lef\at lever 
back towards the \feutral posit\aio\f while mai\ftai\fi\fg\a 
the positio\f of the\a right lever, this will slow th\ae rotatio\f 
of the left wheel \aa\fd cause the machi\fe\a to tur\f i\f that 
directio\f.
To zero turn
While movi\fg i\f a fo\arward directio\f, first pull bo\ath 
co\ftrol levers back u\ftil\a the mower stops o\ar slows 
dramatically.
The\f by alter\fati\fg o\fe lever sli\aghtly to the forwar\ad 
positio\f a\fd the oth\aer i\f the reverse positio\f, 
complete the tur\f.
