ย MULCHING vs SIDE DISCHARGE
ย WHATโS THE DIFFERENCE?
ย MULCHING (Best for lawn health & regular mowing)
Mulching works by cutting the grass multiple times into very fine pieces, then blowing those clippings back down into the lawn.
ย Instead of collecting or throwing the grass away, it becomes natural fertiliser
ย Benefits of Mulching:
- Feeds nutrients back into the soil
- Helps keep the lawn green, thick, and healthy
- No grass to collect or dispose of
- Saves time and reduces waste
ย When to Use Mulching:
- When mowing regularly (little and often)
- In dry or normal conditions
- On lawns you want to keep looking neat and healthy
ย Think of it as cutting + feeding your lawn at the same time
SIDE DISCHARGE (Best for speed & longer grass)
Side discharge simply cuts the grass and throws it out the side of the deck.
No collecting, no fine chopping โ just fast, effective clearing
ย Benefits of Side Discharge:
- Handles long, thick, or overgrown grass easily
- Much faster โ no stopping to empty
- Wonโt clog like a collector in heavy conditions
When to Use Side Discharge:
- When grass is long or wet
- For rough areas, paddocks, or large open lawns
- When you want to cut quickly without worrying about finish
ย Think of it as quick, powerful clearing
SIMPLE WAY TO CHOOSE
- Want a clean, healthy lawn? โ Use Mulching
- Want to cut fast or tackle long grass? โ Use Side Discharge
Most owners use:
- Mulching for regular weekly mowing
- Side discharge when the grass gets too long or conditions are tough
ย Thatโs what makes mowers like the STIGA Tornado 398 so versatile โ you can switch depending on the job.
