Four mowing system: rear discharge

: this system allows mowing grass without the grass collector, and discharging the grass clippings from the back of the lawn mower.

Simply remove the grass collector to let the rear discharge work.

Four mowing systems: mulching plug

This system allows cutting grass without catching it inside the collector, and crushing the clippings into a fine powder before dropping them on the lawn.

Immediate conversion: you will just need to pull out the grass collector, connect the standard-supplied mulching plug, and lower the rear deflector in order to engage the mulching system.

This grass mowing system allows crushing grass clippings and dropping them on the ground. The resulting grass particles are so small, they will be barely noticeable on the lawn. This eliminates the problem of its disposal (reducing any effort and shortening the time-saving). Moreover, grass clippings will break down into nutrients and water for the lawn (grass is 80% water) and will thus ensure a perfectly balanced biological cycle. However, it is worth remembering that, to ensure the greatest mulching results, the lawn should be irrigated and the grass needs cutting at least once a week.

Four mowing systems: side discharge

This system allows mowing grass without collecting the clippings inside the grass collector (it is also possible to collect grass a bit higher than normal, due to the high disposal capacity of the side exhaust deflector).

If you keep entered the mulching plug so as it occludes the grass rear discharge, you will just need to lift the side cover on the side of the mower housing and connect the side deflector with a single gesture.
