About
About TerraClear
TerraClear links aerial mapping with selective rock removal for farms. Drone imagery at roughly five-millimetre ground resolution is processed by computer vision to locate and size rocks; the mobile Rock Map then guides operators by GPS, filters targets by size and records each removal in real time.
The TC100 hydraulic attachment mounts to compatible tractors, skid steers and compact track loaders, collecting rocks 6 to 26 inches across into a one-cubic-yard bucket with minimal soil disturbance. TerraClear reports up to 400 rocks per hour in medium-to-high density fields. Farmers can buy the picker, use maps with other equipment or contract mapped picking services, while the TerraScout autonomous crop and weed-mapping system is targeted for a 2027 commercial release.

Timeline
Events
- 2026-02-19 - Product Launch - TerraClear Launches TerraScout Autonomous Field-Prescription Robot
TerraClear introduced TerraScout, an autonomous robot that captures ultra-high-resolution imagery across entire fields and converts it into field prescriptions for existing farm equipment. Reported performance: maps 1,000+ acres/day, operates up to ~15 mph, and can run ~6 hours autonomously without refueling. Field trials started earlier in 2026, with expanded trials planned for spring 2026.
