Operating Cost
Cost per hour to run a bulldozer, excavator, TLB & grader in South Africa (2026)
By Marcus du Toit · Published 27 Jul 2026 · 9 min read
TL;DR — Real 2026 SA owning-and-operating cost, at 1,800 productive hours/year and R22.50/l bulk diesel:
Shantui SD16 dozer ~R1,150/hr · Cat D6 ~R1,450/hr
Shantui SE215 20t excavator ~R780/hr · Cat 320 ~R1,020/hr
TLB (Bell/JCB class) ~R520/hr · Shantui equivalent ~R430/hr
Shantui SG21-3 140HP grader ~R680/hr · Cat 140 ~R980/hr
Fuel and wages are brand-blind. The gap is ownership recovery — how much capital each machine has to earn back per hour.
"Every contractor knows their diesel price. Almost none of them know their true cost per hour. And that's the number that decides whether a job makes money or loses it." — Marcus du Toit
The four things that make up true cost per hour
Cost per hour on heavy equipment isn't the finance instalment divided by hours worked. It's four separate things stacked on top of each other. Miss any one of them and you're quoting jobs blind.
- Fuel burn — litres per hour × delivered bulk diesel price. Brand-blind. A 160HP dozer burns 18–22 l/hr whether it's Shantui or Cat.
- Operator — wage + provident + safety kit + subsistence, divided by productive hours. Also brand-blind.
- Wear & service — filters, oils, greases, GET (ground engaging tools), undercarriage or tyres, pro-rated per hour. Slightly cheaper on Chinese equipment (parts price), same interval.
- Ownership recovery — (purchase price − expected residual + finance interest) ÷ lifetime billable hours. This is where the brands diverge — hard.
Bulldozer — Shantui SD16 vs Cat D6
Assumptions: 160HP class, 1,800 hrs/year, 10,000-hour life, bulk diesel R22.50/l, operator R95/hr all-in.
| Cost line | Shantui SD16 | Cat D6 |
|---|---|---|
| Fuel (20 l/hr × R22.50) | R450 | R450 |
| Operator | R95 | R95 |
| Wear & service | R220 | R260 |
| Ownership recovery | R310 | R570 |
| Total cost/hr | R1,075 – R1,150 | R1,375 – R1,450 |
Over 10,000 hours, that R300/hr gap is R3 million of margin that stays in your business instead of on the OEM's balance sheet. Full breakdown in the SD16 vs D6 comparison.
20-ton excavator — Shantui SE215 vs Cat 320
The workhorse of SA earthworks. Same 20-ton class, same digging cycle time, same operator, same fuel burn (13–15 l/hr).
| Cost line | Shantui SE215 | Cat 320 |
|---|---|---|
| Fuel (14 l/hr × R22.50) | R315 | R315 |
| Operator | R95 | R95 |
| Wear, GET & service | R150 | R180 |
| Ownership recovery | R220 | R430 |
| Total cost/hr | R720 – R780 | R970 – R1,020 |
See the SA excavator buyer's guide for full pricing across the 6t–37t range.
TLB (backhoe loader) — the smallest cost per hour
TLBs are the lightest fuel burn on this list (8–11 l/hr) and the cheapest capital. That's why they're the SA contractor's default first machine.
| Cost line | Bell/JCB TLB | Shantui-class TLB |
|---|---|---|
| Fuel (10 l/hr × R22.50) | R225 | R225 |
| Operator | R85 | R85 |
| Wear, tyres & service | R95 | R75 |
| Ownership recovery | R120 | R55 |
| Total cost/hr | R480 – R525 | R415 – R440 |
Compare to open-market TLB hire rates in SA — dry-hire runs R550–R750/hr. That gap is your gross margin per hour.
Motor grader — Shantui SG21-3 vs Cat 140
140HP class, provincial-road and mine-haul work. Diesel burn 14–17 l/hr, similar operator wage.
| Cost line | Shantui SG21-3 | Cat 140 |
|---|---|---|
| Fuel (15 l/hr × R22.50) | R340 | R340 |
| Operator | R95 | R95 |
| Wear, blades & service | R120 | R145 |
| Ownership recovery | R135 | R395 |
| Total cost/hr | R640 – R680 | R950 – R980 |
The grader is where the ownership-recovery gap is widest — a Cat 140 lands at R4.8–R5.3m, a Shantui SG21-3 at ~R2.2m. Full context in the SA rental rates: Cat vs Shantui ROI pillar.
Where the numbers break down
Two scenarios move these figures fast:
- Low utilisation. Drop from 1,800 to 900 productive hours a year and ownership recovery per hour doubles. This is why marginal-use machines belong on rental or a full-maintenance lease, not on your balance sheet.
- Downtime. If a machine sits waiting for a part, the finance instalment, insurance and operator wage keep running. A 3-day parts wait on a R1,000/hr excavator at 10 hrs/day = R30,000 of dead cost — the entire savings on a cheap filter, wiped out.
My honest take
On fuel and wages, everyone's equal. On wear parts, Chinese equipment is 15–25% cheaper. On ownership recovery — the biggest single line — Shantui runs at roughly half the premium-brand cost per hour, and that's what carries the total number down.
For jobs priced on tender rate cards, cost per hour is your true breakeven. Get it wrong by R200/hr on a 1,800-hour year and you've lost R360,000 in margin per machine, per year. Get it right and every hour a Shantui runs against a Cat contract rate is R250–R300 of extra gross profit into your business.
