HT18C Mini Excavator for Landscaping & Narrow Access
The HT18C mini excavator features a 1,100 mm width, 1,950 mm digging depth, and a 17 kW Rato engine for landscaping and narrow-access work. [Download the full HT18C spec sheet (PDF)] or contact us for a custom OEM solution.

Compact dimensions make access easier to plan
The first question on a small excavation job is often not digging depth, but whether the machine can reach the work area. The HT18C has an overall width of 1,100 mm and an upper frame width of 960 mm. For projects involving garden entrances, residential properties, orchards or other restricted working areas, these dimensions give buyers a clear starting point when checking site access.
The machine also has a 760 mm tail swing radius and a 1,580 mm minimum turning radius. These figures matter when there is limited space to reposition the excavator after entering the work area. Before ordering, measure gates, paths and other access points rather than relying only on the nominal machine width.
Useful digging range for smaller excavation jobs
HT18C reaches a maximum digging depth of 1,950 mm and a horizontal digging reach of 2,880 mm. Maximum digging height is 2,490 mm, while maximum dumping height is 1,635 mm. This working range covers many everyday applications, including garden excavation, drainage preparation, orchard maintenance, trenching and residential renovation.
With a standard bucket capacity of 0.02 m³ and an operating weight of 1,400 kg, the HT18C sits in a practical size range for buyers who need more working capability than a basic compact machine but do not have room for a larger excavator.
Engine and machine configuration
The HT18C uses a Rato 739CC twin-cylinder gasoline engine rated at 17 kW. The main valve is supplied by Tengfei, while swing rotation speed is rated at 12 RPM. The listed maximum climbing gradient is 30°.
For buyers comparing a mini excavator for tight spaces, these specifications provide a more useful basis for evaluation than machine size alone. The combination of compact dimensions, digging range and engine output should be considered together with the actual ground conditions and application.
Suitable applications and attachments
The HT18C is suited to work where access and maneuverability are important. Typical applications include landscaping, orchard maintenance, residential renovation, garden excavation and smaller trenching projects. It can also be configured with interchangeable attachments for different types of work.
The available product information lists more than 20 interchangeable attachments, including options for digging, breaking, drilling and material handling. Attachment requirements should be confirmed before quotation so the machine can be supplied according to the intended application.
What to include in an HT18C inquiry
For an export purchase, provide the destination country, intended application, required attachments and any access limitations when requesting a quotation. These details help determine the appropriate machine configuration and allow shipping, spare-parts requirements and dealer cooperation to be discussed before ordering.

What is the overall width of the HT18C mini excavator?
The HT18C has an overall width of 1,100 mm and an upper frame width of 960 mm. When checking a narrow entrance, buyers should allow additional clearance rather than choosing an opening that is exactly the same width as the machine.
How deep can the HT18C mini excavator dig?
The maximum digging depth is 1,950 mm, with a maximum horizontal digging reach of 2,880 mm. The required trench or excavation depth should be compared with these figures before purchase.
Is the HT18C suitable for landscaping work?
Yes. The compact overall width, 1,580 mm minimum turning radius and 1,950 mm digging depth make the HT18C suitable for many landscaping, garden excavation and property-maintenance applications where access is restricted.
Can the HT18C be used for orchard maintenance?
The machine's compact dimensions make it applicable to orchard maintenance and other work where working space between trees or around existing property is limited. The actual suitability depends on the site's ground conditions and available access.
