This mulching kit can be installed on the RMA 339 C and RME 339 to return your clippings to the lawn for greener, healthier grass.
Please note, it requires some assembly, which is detailed in the user manual provided. A torque wrench is the ideal tool, but a regular spanner can be used.

"Mulching is a great alternative to chemical fertilisers. And it’s very simple – instead of collecting the clippings in a grass catcher box or bag when you mow your lawn, mulching mowers shred the grass finely and return it to the turf as a natural, organic fertiliser. It supplies the lawn with just the right nutrients it needs, including nitrogen, phosphorus and potash."
