Which digs deeper, the HY18B or the MS15?

The HY18B digs to 2,050 mm, about 80.7 in. The MS15 is rated at 72.83 in, so the HY18B reaches roughly 8 in deeper.

Is the HY18B worth about $3,800 more than the MS15?

It is if you need the Kubota Tier 4 diesel, the included hydraulic thumb and quick hitch, and the extra digging depth and reach. If you only dig shallow trenches and move light material, the MS15 does the job for less.

Which is easier to tow?

The MS15 at 1.5 tons is the lighter machine, so it fits smaller trailers and tow vehicles. The HY18B is 1,800 kg and needs a heavier setup.

Do both come with a thumb?

Only the HY18B lists a hydraulic thumb clamp in the box. The MS15 is sold as the machine, with attachments available separately.

Which has the better engine for parts and service?

The HY18B uses a Kubota D722, a common diesel with broad dealer support. The MS15's 13.5 hp engine brand is not stated, so check parts availability before buying.

Which is better for tight spaces?

The HY18B's side swing boom helps you dig along walls and fences. The MS15 lists a 55.1 in minimum swing radius, which matters in narrow yards.
