Verticutter Cartridge 

 
Verticutting 

can be thought of as “Vertical mowing” where thin and closely spaced tines remove lateral growth and 

moss. This encourages grass to tiller and creates a denser, more regimented sward. The resulting lines left by the 
action of the blades should grow out within two or three days in the growing season, if not raise the height of cut. 

 

 
Regular (up to weekly) and shallow in-season verticutting will prevent excessive thatch build up. 
 
 

Scarifier Cartridge 

 
The Scarifier 

cartridge is Allett’s most popular cultivation cartridge and is designed to remove thatch, surface debris 

and dead moss. This cartridge also helps lift lateral growth upright before mowing. 
 
The scarifier has a custom design which helps to keep your lawn surface healthy and disease-free, by allowing air 
and water to penetrate the soil surface. The machine is designed with rotating tines that pull out the dead grass 
and moss to enable the passage of nutrients into the soil. 
 
The rotating spring tines are relatively gentle on the lawn and this cartridge can be used most of the year without 
fear of damage to keep on top of thatch levels as well as being useful to collect up leaves during the autumn. The 
use  of  the  spring  tine  allows  for  safe  cultivation  where  tree  roots  may  be  close  to  the  surface.  This  is  the  best 
cartridge for beginners to turf cultivation as it is unlikely to cause damage if set too deeply but will give great results 
if used regularly. 
 
We suggest scarifying once a month during the mowing season to keep on top of thatch levels. 
 
 

UC 10-BLADE CUTTING CYLINDER 

 

UC 10-bladed cutting cylinder (reel) cartridges are also available where the precision finish of a golf or bowling 
green is required. These are available in 43 & 51 cm widths. This allows mowing at shorter grass heights as low 
as 4mm but requires regular mowing of 2 or more times per week.

 

 
 

SETTING CYLINDER / REEL BLADES ON CUT 

 
The blades are correctly set when the cutting cylinder (reel) lightly brushes the bottom blade (bed knife) across the 
full width as the cylinder (reel) is turned. The blades act like a pair of scissors. As a test, correctly adjusted blades 
will cut a piece of good quality writing paper (80g/m

2

) across the width of the blade.  

 
The cutting cylinder (reel) should only be adjusted if the grass is not cut cleanly and evenly. 
 
To set blades correctly on cut: 
 

1.  Remove battery from machine.  

 

2.  Tilt the mower back and wedge securely. 

 

3.  Remove the grass bag. 

 

4.  Check the cleanness of cut with paper across the cutting width. Always wear gloves. 

 

5.  Turn the adjuster screws clockwise with a flat bladed screwdriver a little at a time and check the cleanness 

of cut with a piece of paper as you go along. It may be necessary to only adjust one side to get a nice 
scissor action. 

 
Note: setting the blades with heavy contact can cause damage to your mower! 
 

 
STORAGE 

 

If the mower is to be left standing for long periods, adjust the height of cut so that the tines are clear of the ground.  

 

Before storage remove all the debris from the mower and cartridge with a brush and apply a light coating of oil.  

 

A storage stand is available to store up to 3 cartridges, please contact your local dealer for information.
