DIY hydrostatic 4x4 tool carrier built on Mercedes G-Wagon rigid axles, running a custom 83" brushcutter deck

Built a custom hydrostatic tool carrier and an 83"mower

Needed a dedicated compact tool carrier with high hydraulic flow to clear overgrown land, so I designed and built this rig from the ground up.

The carrier: Mercedes G-Wagon rigid axles, 4x4, full hydrostatic drive, custom CAN-bus / ESP32 digital telemetry.

The deck: 83" cut width, Hardox mono-rotor blade running on a machined heavy-duty axle spindle.

The lift system: 2:1 cable multiplier powered by a hydraulic ram with a nitrogen accumulator for floatation over rough ground.

Just took it out for the first brutal test in thick brush. Everything held together.

​Fabricated an 83" (212 cm) high-inertia brush mower from raw steel for my 4x4 rig. Solo build.

Needed a brutal brush cutter that wouldn't fold on hidden stumps, so I fabricated this:

Frame & Structure: Strenx S700 high-strength steel.

Skin / Deck: S500 plate.

Welding: ESAB AristoRod 69 wire for high-tensile joint strength.

Spindle: Lathe-turned shaft with heavy tapered roller bearings.

Drive: Direct-driven by Rexroth hydraulics.

Rig: Mounted on an articulated Bucher frame with locked Mercedes G-Wagon solid axles.

Survived brutal testing in thick overgrowth without bending. Full build video in progress—happy to answer any metal, welding, or geometry questions!
