A Practical, No-Nonsense Guide for South African Contractors If there’s one thing that can bring an excavator to its knees faster than a blown hose or a leaking final drive, it’s an overheating hydraulic system.

Stop Wasting Time, Money, and Sweat on Half-Assed Repairs Let’s get straight to the point: Most contractors are terrible at this .They stand over a busted final drive, hydraulic pump, or swing motor and say, “I think we can fix it.” And then three days later, the machine is still broken, your operator is pissed, the client is furious, and your wallet is getting fleeced faster than diesel prices.
