The Hitachi DX40 Dozer is known for its robust design and reliable performance. I've used it for several heavy-duty projects and it has never let me down.
I've been working with the DX40 for a couple of years. It's particularly good in difficult terrain and has a good maintainability score.
The DX40 does require some regular maintenance but it's worth it for its reliability. It’s a solid choice for medium to heavy-duty tasks.
