What Equipment Do I Need to Dig a Drainage Ditch?

An open ditch is not a french drain. You are cutting a swale or a channel that water can see. A mini excavator is the right shape: you can cut a wide, sloped invert. A Barreto gives you a slot that will slough and clog. A CTL can pull a shallow swale across a lawn. Pick based on depth, not on which brochure looked agricultural.

Typical pairing

Yard swale: E35 or even just a CTL. Real ditch: 305.5 + dump trailer. Do not use a walk-behind trencher and call the slot a ditch — it will not stay open.

Open channel vs pipe

If you are about to drop pipe in and bury it, that is a trench guide. If it stays open, you want a wide, stable side slope. E35 for yard swales; 305.5 for a real ditch along a lane.

Where the dirt goes

Spoil on the downhill side becomes a dam. Spoil on the uphill side can work as a berm if you mean it. A dump trailer is for when neither side should keep the dirt.
