AMK 043, AMK 048 mulching kits
With a mulching kit, a conventional lawn 
mower can be converted into a multi-
mower. For this purpose, the mowing 
blade must be replaced with the multi-
blade.
A multi-mower can be used as a grass 
collector (with grass catcher box), a rear 
discharge mower (with discharge flap 
closed), or as a mulching mower (with a 
mulching key).
Observe the instruction manual for the 
lawn mower, particularly the "For your 
safety" and "Maintenance" sections. The 
instructions for blade maintenance must 
always be observed.
Disconnect the spark plug socket (RM), 
mains plug (RME) or safety plug (RMA) 
before performing any work on the lawn 
mower.
Before each use, perform a visual check to 
ensure that the mulch insert, multi-blade 
and blade fastening are in good condition.
Only use the mulch insert in conjunction 
with the multi-blade.
3.1  Installing the multi-blade
● Remove the mowing blade (see 
illustration and instruction 
manual for lawn mower). Discard the 
blade fastening screw and if necessary 
the spring washer.
● Clean the blade contact surface and 
blade bushing.
● Assemble the multi-blade: Hook the 
upper blade (B1) into the lower 
blade (B2) as shown in the illustration. 
Ensure that the bores in both blades are 
aligned.
● Fit the multi-blade (B) with the curved 
wings pointing upwards (towards the 
mower) onto the blade bushing.
● Use a suitable wooden block (1) to 
counterhold the multi-blade (B).
● Apply Loctite 243 to the thread of the 
blade fastening screw (C) or blade 
fastening screw (D).
● RM 443, RM 448, RMA 443, RMA 448:
Screw in the blade fastening screw (C) 
together with the retaining washer (E) –
observe convexity – and tighten to a 
torque of 60 - 65 Nm.
● RME 443:
Screw in the blade fastening screw (D) 
and tighten to a torque of 10 - 15 Nm.
3.2 Mulch insert
Inserting the mulch insert:
● Open the discharge flap and hold 
it open.
● Insert the mulch insert (A) in the 
discharge chute and press from above 
until both retaining lugs (1) audibly 
engage in the housing (see illustration).
● Close the discharge flap. The lawn 
mower is ready for mulching.
Removing the mulch insert:
● Open the discharge flap and hold it 
open.
● Lift the detent catch (2). Pull the mulch 
insert diagonally upwards out of the 
discharge chute.
● For use as a rear discharge mower, 
close the discharge flap, for grass 
collecting, attach the grass catcher box.
