direct the grass discharge toward bystanders, 
traffic, cars or buildings nor allow anyone within 
50 feet of the machine while in operation.  Thrown 
objects can pass through glass windows and 
some walls of buildings.  There is extreme risk of 
danger from thrown objects or being cut by the 
blades of the mower.  Never operate the mower in 
an enclosed area without good, approved 
ventilation.  Exhaust fumes are dangerous. 
 
 
 

 

Initial Operating Safety Guidelines 

 Read and understand the warnings on the 

general warning decal on the mower. 

 Keep both feet on the foot platform at all times. 

 Know the controls and how to stop quickly.

 

 Before attempting to start the engine, follow all 

starting instructions below and in the engine 
operator’s manual. 

 Look behind before backing up. 

 Before leaving the operator’s seat, even  

momentarily, turn off the blade clutch 
engagement switch and apply the parking 
brake.  Keep others from coming near the 
mower.  Get back on the mower as soon as 
possible. 

 When leaving the Wright mower unattended, 

turn off the blade clutch engagement switch, 
apply the parking brake, stop the engine and 
remove the key.  Never leave the machine 
unattended on a slope in case someone 
disengages the parking brake. This could 
create a rollover hazard. 

 When transporting, driving onto transport 

vehicles, into buildings, across parking lots 
or otherwise not mowing grass, turn off the 
blade clutch engagement switch to reduce 
risk of thrown objects and rotating blade 
hazard.  After coming to a stop apply the 
parking brake, stop the engine and remove 
the key. 

 Before performing any maintenance or repair 

service, disengage power to blades, apply 
the parking brake, stop the engine, remove 
ignition key and spark plug wire from spark 
plug(s). 

 All operators of this mower should exercise 

caution when driving this mower at high 
speeds.  Sudden acceleration or 
deceleration may cause serious injury. 

 DO NOT allow inexperienced persons to 

operate the mower until they have read and 
understood these safety instructions.  
Operate the mower at slower speeds while 
becoming familiar with it. 

 The grass discharge chute deflector must be 

installed at all times and in the down position 
except that it may be raised when cleaning 
out the deck, or a grass catcher is installed 
or a mulch kit and block-off plate is properly 
installed. 

    

WARNING

 

 If the mower discharges grass clogs, turn off the 

blade clutch switch, apply the parking brake, 
stop the engine and remove the key before 
removing obstruction(s). 

 Keep all shields and covers in place, namely, all 

blade and belt covers, engine shields, and 
grass discharge chute deflector. 

 Keep hands, feet and clothing away from 

rotating parts, especially the rear wheels, 
blades, engine flywheel, belts and pulleys. 

 Do not touch engine, muffler or hydraulic 

system while engine is running or soon after 
it is stopped.  These areas can be so hot as 
to cause severe burns. 

 Clean grass, leaves and lubricant spills from 

surfaces after use to prevent fire hazard. 

 Be alert for traffic when crossing roads or 

operating near roadways. 

 Before climbing curbs, crossing gravel drives, 

sidewalks or roads, turn off the blades and 
wait for them to stop, then place deck into 
transport position. 

 
 
 
 
 

Operation In Forward Direction 

    

WARNING

 

Operate the mower slowly until you become 
familiar with how the mower operates.  Do not 
operate the mower faster than conditions allow.  
For example, hills, wet or bumpy ground, dim light 
or high grass are all conditions requiring slower 
speeds.  Never operate the mower at the highest 
speed unless you are on level, wide, open areas 
of clearly visible ground or transporting on paved 
areas.  Speeding with any mower is dangerous, 
and so is traveling faster than conditions should 
permit on this mower.  Sudden stops from 
excessive speed or falling off the mower may 
cause serious injury or death.
