Pneumatic precision seed drill ValoTerra

disc4-row12-row

Overview
The ValoTerra is a next-generation 100% electric single-seed planter from MONOSEM. Its 56 V architecture, vacuum-sealed metering box and electric seed-disc drive deliver precise seed placement, higher working speeds and reduced setup and maintenance time.

Key benefits

• 100% electric 56 V architecture with optional generator supply (~5.6 kW) — consistent power for high-precision seeding
• Vacuum-sealed metering box that keeps seeds on the disc up to ~18 km/h for reliable singulation
• ASG (Active Seed Guidance) and conveyor-brush option for controlled seed trajectory and improved spacing at speed
• MicroSmart microgranule system: 20 L hopper per row, 2–35 kg/ha dosing range, row-by-row control
• FertiSmart fertilizer unit with gravity/pumped outlets and row-by-row section control up to ~600 kg/ha
• ISOBUS compatibility, Operations Center connectivity and Monosem Plus app for calibration and monitoring

Crops, rows, tillage & spacing (summary)

• Crops: maize, sugarbeet, sunflower, rapeseed, soybean and other single-seed crops
• Number of rows: 4 to 12 rows (model/frame dependent)
• Inter-row spacing: 40 to 80 cm (many frame-specific configurations available)
• Tillage: conventional, reduced till, no-till

Metering & distribution

• Vacuum-sealed metering box for seed adhesion at high speed (validated to ~18 km/h)
• Electric drive in the seed-disc shaft for precise metering across speeds
• Patented 3-tooth singulator and floating insert to improve singulation and reduce torque
• Metering options: chute (Essential) or conveyor-brush (Ultimate; ASG ready)
• Brush conveyor speed proportional to tractor speed to avoid rollback and maintain spacing

MicroSmart microgranulation

• 20 L MicroSmart hopper per row for near-seed microgranule placement
• Accurate dosing approximately 2–35 kg/ha depending on product and spacing
• Row-by-row microgranulator with tool-free change via dosing screws; two independent units configurable per row

Seed hopper and handling

• Translucent seed hopper 70 L (~160,000 maize seeds) for extended autonomy
• Quick-empty chute and adjustable shutter to isolate seed supply
• Visible levers and notched scales for fast, intuitive setup and adjustments

Unit & ground contact systems

• Heavyweight metering unit with adjustable pressure springs (unit pressure up to ~325 kg depending on config)
• 19 depth settings and V-shaped furrow for seed fixation
• PRO wheel Ø ~295 mm (pressure/angle adjustable, retractable up to 4 cm); gauge wheels Ø 450 mm x 115 mm
• Double opener discs Ø 450 mm for penetration and reduced mud spatter; trash wheels and optional clod removers
• Monoshox shock absorber and patented SmartAccess raising system for maintenance access

Fertilization (FertiSmart)

• FertiSmart unit supports gravity or pumped outlets and fluted metering cylinders for varied fertilizer types
• Row-by-row section control and variable-rate capability (terminal/GPS-managed)
• Flow rates configurable up to ~600 kg/ha by gravity; MSM/ISM motorization options

Versions & configurations

• Essential: chute metering, recommended max speed ~12 km/h, standard double-disc fertilizer applicator
• Ultimate: conveyor-brush (ASG ready) or chute, recommended max speed ~16 km/h, fast swap between belt and chute (<2 minutes per row)

Frames & chassis

• Multiple frame types (rigid, telescopic, multislide, double-bar folding, TFC2, wingfold) to suit row counts and transport widths

Connectivity & software

• ISOBUS-compatible control (SeedStar M or equivalent) for population, singulation and spacing monitoring
• Operations Center connectivity for data logging and remote monitoring; Monosem Plus app for calibration and checks

Other highlights

• Optional generator solution (~5.6 kW) — avoids need for a battery in standard setup
• Fast crop switches: less than 1 minute per row to change seed discs (Ultimate: belt/chute swap <2 min per row)
• Optimized seed/input densities and lean metering for efficient input use
