An excavator is a tracked digging machine, and choosing the right one in South Africa is mainly a question of three things: how the machine gets onto your site, how deep it needs to dig, and how much material it moves per bucket. This guide helps you match a machine to your job using the real MCM and Yuchai excavator range.
Choosing an excavator in South Africa comes down to three things: how the machine gets onto your site, how deep you need to dig, and how much material you move per bucket. Get those right and the rest follows. A 1.8-tonne mini excavator like the Yuchai U18 fits through a 1.08 m gate and digs 2.3 m deep — ideal for plumbing, landscaping and vineyard work. A 5.7-tonne medium machine like the Yuchai YC60-9 digs 3.72 m deep with a 0.21 m³ bucket for trenching, foundations and bulk earthworks. This guide compares the full MCM excavator range by real specification so you can match a machine to your job and budget.
Quick answer
For tight access, indoor work and light trenching, choose a mini excavator (1.8–4 tonnes). For foundations, services trenching and general construction, choose a medium excavator (5–8 tonnes). Mini excavators transport on a standard braked trailer; medium machines need a flatbed or rollback. MCM stocks both, with nationwide delivery, finance and a National Parts Division.
Excavator size classes in South Africa
Quick answer: An excavator size class is a weight band that describes what a machine can do. South Africa generally uses three: mini excavators under 4 tonnes are designed to work in tight access, medium excavators of 5 to 8 tonnes provide greater depth and bucket size, and wheel-crawler machines offer road-going mobility between sites.
Excavators are grouped by operating weight, and weight is the single best predictor of what a machine can do. South African dealers and rental yards generally use three classes:
- Mini excavators (under 4 tonnes) — compact, low ground pressure and easy to transport. Best for landscaping, plumbing and drainage, vineyards, swimming pools and confined urban sites. The Yuchai U18 (1.8 t) and MCM 16DS sit at the small end; the Yuchai U35 (3.86 t) at the top.
- Medium excavators (5–8 tonnes) — the workhorse class for general construction, services trenching, foundations and farm earthworks. The Yuchai YC60-9 (5.7 t) is the volume seller here.
- Wheel-crawler excavators — machines such as the MCM 90WDT and 120WDT combine a digging arm with road-going mobility for sites where you move often between work areas.
MCM and Yuchai excavator range compared
Quick answer: The MCM excavator range offers machines from 1.8 to 5.7 tonnes. Digging depth provides 2.31 metres on the U18 up to 3.72 metres on the YC60-9, while bucket capacity involves 0.05 to 0.21 cubic metres and transport width consists of 1.08 to 1.92 metres, so the table below helps you shortlist quickly.
The table below uses real manufacturer specifications from the MCM range. Use digging depth and transport width to shortlist, then confirm bucket capacity against the material you handle most.
| Model | Class | Weight | Bucket | Max dig depth | Max reach | Engine | Transport width |
|---|---|---|---|---|---|---|---|
| Yuchai U18 | Mini | 1 800 kg | 0.05 m³ | 2 310 mm | 4 125 mm | Yanmar 14.5 kW | 1 080 mm |
| Yuchai U35 | Mini | 3 860 kg | 0.12 m³ | 3 170 mm | 5 557 mm | Yanmar 18.2 kW | 1 800 mm |
| Yuchai YC60-9 | Medium | 5 700 kg | 0.21 m³ | 3 720 mm | 6 065 mm | Kubota 35 kW | 1 920 mm |

How to choose the right excavator: 5 steps
Quick answer: Choosing an excavator involves five checks in order: site access, digging depth, bucket size, undercarriage, then engine and finance. This sequence allows you to eliminate unsuitable machines quickly, because the first check that fails defines the machine before cost or brand is even considered.
- Start with site access. Measure the narrowest gate, doorway or passage the machine must pass. The Yuchai U18 retracts to 1 080 mm wide; a medium YC60-9 needs 1 920 mm. If you cannot get the machine in, nothing else matters.
- Match the digging depth. Note the deepest trench or foundation you dig. A mini U18 reaches 2.31 m, the U35 reaches 3.17 m and the medium YC60-9 reaches 3.72 m. Buy for your deepest regular job, not your average one.
- Size the bucket to the material. Bucket capacity sets your productivity: 0.05 m³ (U18) suits cables, irrigation and landscaping; 0.12 m³ (U35) suits drainage and footings; 0.21 m³ (YC60-9) moves bulk soil and trenches faster.
- Choose tracks and undercarriage. Rubber tracks (standard across the MCM mini range) protect paving and lawns and run quietly; the U18’s expandable undercarriage widens for stability and retracts for access.
- Confirm engine, support and finance. MCM mini excavators run proven Yanmar engines and the YC60-9 a Kubota engine, all backed by MCM’s National Parts Division. Ask about equipment finance before you commit.
Mini vs medium excavator: which for your job?
Quick answer: A mini excavator is a compact machine that is designed to prioritise access, transport and low running cost. A medium excavator is a 5-to-8-tonne machine that provides greater digging depth, a larger bucket and a dozer blade, and enables you to clear foundations and bulk earthworks far faster.
A mini excavator wins on access, transport and running cost. It loads onto a braked trailer, digs cleanly around existing services, and sips diesel from a small tank (23 L on the U18). Vineyards, smallholdings, plumbers, landscapers and pool builders are the natural buyers. Best for: tight-access trenching, drainage, landscaping, vineyard work and pool installation.
A medium excavator wins on output and depth. The YC60-9’s 35 kW Kubota engine, 0.21 m³ bucket and 3.72 m reach clear foundations and service trenches far faster, and the dozer blade lets it backfill and level without a second machine. Building contractors, civils and larger farms get their money back in productivity. Best for: foundations, services trenching, bulk earthworks and farm dam work.
If your work spans both — tight-access jobs and heavier earthworks — many buyers run a mini for daily work and hire a medium machine when a job demands it. MCM’s sales team can model both routes against your workload.
