Final answer:
Mini excavators can come with either steel or rubber tracks. The choice depends on job requirements, with steel tracks being durable for rough terrain, and rubber tracks being gentle on delicate surfaces.
Step-by-step explanation:
Mini excavators come with either steel tracks or rubber tracks. The type of track chosen is typically based on the work environment and the needs of the job. Steel tracks are used for rough terrain where durability and traction are essential, like on a construction site with rocky or uneven surfaces.
On the other hand, rubber tracks are better suited for jobs on delicate surfaces where the risk of damage must be minimized, such as on lawns or paved areas. Rubber tracks are also known for reducing vibration and being less noisy than steel tracks.
When selecting a mini excavator, it's crucial to consider the type of surface you'll be working on most often to decide between rubber and steel tracks.
