U-Shape Cutter

Single-pass all-sided row cutting in vineyards

The U-Shape Cutter is a rear-hinged portal attachment designed for single-pass cutting of vineyard rows. By enclosing the row with one horizontal and two vertical cutting decks, it trims both sides and the top in one continuous movement. The U-Shape Cutter combines one-pass operation, autonomous guidance, and adjustable canopy shaping into a single vineyard cutting solution. This reduces labor, improves consistency, and increases productivity over the full season.

100% Autonomous | 100% Electric

Features & Benefits

The U-shaped frame surrounds the row and cuts the entire canopy profile in a single passage. This reduces the number of operations needed to maintain vineyard rows and improves cutting consistency.

Key benefits:
• Cuts both sides and the top in one pass
• Reduces total working time
• Eliminates repeated passes through the same row
• Improves overall field productivity

Result: faster vineyard cutting with lower labor input and more uniform results.

The system operates autonomously, removing the need for constant driver correction to keep the machine centered in the row. This is especially important for portal-style cutting, where small deviations can lead to uneven cuts or vine damage.

Key benefits:
• No manual steering corrections
• Consistent row alignment during operation
• Reduced risk of crop damage
• Repeatable cutting accuracy across the vineyard

Result: precise and reliable pruning without operator fatigue or human error.

The cutting decks can be positioned to match different vineyard structures, training systems, and target cutting heights. This allows growers to tune the machine to their exact canopy management strategy.

Key benefits:
• Adjustable cutting height
• Adaptation to different vine structures
• Flexible setup for different vineyard systems
• Better fit to seasonal growth conditions

Result: one attachment that can be adapted to a wide range of vineyard layouts and pruning requirements.

The side cutting decks can be adjusted in angle and distance from the row, allowing growers to control canopy width and shape. This makes it possible to create narrower, wider, or pyramidal profiles depending on vineyard goals.

Key benefits:
• Adjustable canopy width
• Pyramidal shaping option
• Better control of canopy thickness
• Improved light penetration and airflow

Result: optimized vine architecture for healthier growth and better fruit quality.

The hinged system continuously compensates for uneven or slippery terrain to maintain the pre-set cutting height. This keeps pruning consistent even when the robot moves through changing ground levels.

Key benefits:
• Maintains cutting height on slopes
• Adapts to uneven terrain automatically
• Reduces the need for manual correction
• Preserves consistent pruning quality

Result: uniform cutting performance across flat, sloped, and irregular vineyard terrain.

The system continuously adjusts its position to remain vertically aligned with the row and symmetrically centered in the passage. This is critical on slippery terrain, where the machine can shift relative to the vines.

Key benefits:
• Maintains center alignment in the row
• Keeps cutting decks symmetrical to the vines
• Compensates for machine drift on slopes
• Preserves cutting precision in difficult conditions

Result: clean, even pruning with reduced risk of misalignment or uneven cuts.

A dedicated protection system prevents damage if wires or debris become jammed in the cutting decks. A mechanical fuse releases the frame under abnormal load, and a sensor immediately stops the platform.

Key benefits:
• Protects the frame from excessive force
• Stops operation automatically during jamming
• Reduces risk of major damage
• Increases operational safety and reliability

Result: lower downtime and longer attachment lifespan in real vineyard conditions.

The U-shaped frame folds automatically before the robot changes rows. This prevents interference with posts, wires, and other vineyard structures during transitions.

Key benefits:
• Safer movement between rows
• Reduced risk of collision or jamming
• Faster and smoother row changes
• Improved workflow continuity

Result: more efficient vineyard operation with less interruption between passages.
