Slow manual labour
Hand-filling road shoulders is extremely time-consuming. A single road section takes an entire shift for a full work crew. With the KRW 290, one operator can complete the same section in a fraction of the time.

3x faster road shoulder repair
One operator. One machine. Even fill along the entire road section. The KRW 290 road widener by KOVACO replaces an entire work crew for shouldering, widening and trench backfilling.

Do you recognise these problems?
Why traditional methods fall short
Uneven backfill
Manual backfilling never achieves a consistent height and width of material. The result is poor quality and requires repeated repairs.
Rising labour costs
Manual shoulder repair requires 4–6 workers. With the KRW 290, one operator is enough — the labour cost savings are immediate.
