Operation

Several factors can affect how well your machine cuts 
grass, Following proper mowing recommendations 
can improve the performance and life of your 
machine. 

Often cutting height is a matter of personal 
preference. Typically, you should mow the grass 
when it is is between three and five inches high. 
The proper cutting height range for a specific lawn 
will depend upon several factors, including the 
type of grass, the amount of rainfall, the prevailing 
temperature, and the lawn’s overall condition. 

Cutting the grass too short causes weak, thin grass 
plants, which are easily damaged by dry periods and 
pests. Cutting too short is often more damaging than 
allowing the grass to be slightly higher. 

Letting grass grow a bit longer—especially when it 
is hot and dry—reduces heat build-up, preserves 
needed moisture and protects the grass from heat 
damage and other problems. However, allowing grass 
to grow too high can cause thin turf and additional 
problems. 

Cutting off too much at one time shocks the plant’s 
growth system and weakens the grass plants. A 
good rule of thumb is the 1/3 rule: to cut no more 
than one third of the grass height, and never 
more than 1 inch at a time. 

The amount of grass you are able to cut in one pass 
is also effected by the type of mowing system you are 
using (for example, broadcasting with side discharge 
decks can process a much larger volume of grass 
than mulching does). 

For extremely tall grass, set the cutting height at 
maximum for the first pass, and then reset it to the 
desired height and mow a second or third time.

Don’t cover the grass surface with a heavy layer of 
clippings. Consider using a grass collection system 
and starting a compost pile.
