In 2026, mini excavators have become the ultimate "pocket rockets" for residential landscaping. A frequent question from DIY enthusiasts and contractors is: "Is the 1.5-ton Tovisen QS-18 deep enough for a backyard pond?"

Based on our technical specifications and field testing, the QS-18 isn't just capable—it's specifically engineered for these high-precision, narrow-access environments.

1. Digging Depth: Surpassing Residential Standards

A standard ecological pond requires a depth of 1.2 to 1.5 meters. The QS-18 offers significant headroom:

• Max. Digging Depth: Reaches 1991mm, nearly 2 meters deep.

• Application Advantage: This allows for deep-water zones or drainage pipe trenching without reaching the machine's mechanical limits.

• Working Range: With a 3356mm Max. digging radius, you can cover a large area without repositioning the machine.

2. Accessibility: Designed for the "Narrow Gate" Problem

The biggest obstacle for backyard projects is entry. The QS-18 is built for tight maneuvers:

• Ultra-Compact Width: A total width of only 1120mm allows it to pass through standard garden gates.

• 360-Degree Rotation: The 360-degree body rotates freely, allowing the operator to work against walls or fences with precision.

• Turf Protection: Equipped with wear-resistant engineering rubber tracks to minimize damage to expensive landscaping.
