vineyardhigh ground clearancewith cab

Overview
Designed for narrow vineyards, the OPTIMUM 345 high-clearance straddle tractor delivers unmatched agility, superior maneuverability and all-season versatility. Equipped with the PELLENC Multifunction system, it handles every vineyard task from maintenance to harvesting throughout the year. The OPTIMUM 345 combines comfort and ease of use with high productivity thanks to adjustable undercarriage heights, hydraulic variable track and a very tight turning radius.

Key advantages

• Three frame clearance heights: 1.40 m (fixed frame, without harvesting head or tilt correction), 1.50 m and 1.65 m with tilt correction up to 10% to suit different trellis heights.
• 90° turning angle and minimum turning radius of 3.4 m for fast, efficient U-turns even on the narrowest headlands.
• Hydraulic variable track adjustable from the joystick to adapt to inter-row widths from 0.9 m to 1.5 m.
• Capability to overcome slopes up to 40% depending on attachments and conditions.

Comfort & cabin

• Safety cab, pressurized and filtered category 4 (EN 15695) protecting the operator from dust and plant protection products; cab equipped with air conditioning, heating and soundproofing.
• 315° panoramic visibility with 12 work lights for excellent visibility day and night.
• GRAMMER pneumatic seat with vertical and longitudinal suspension, automatic weight detection, heated, ventilated and anti-vibration.
• Top-of-the-range cabin equipment including Bluetooth radio, USB and 12 V sockets, numerous storage compartments and a refrigerated compartment; several high-definition color cameras with night vision available depending on model/options.

Driving & controls

• EASY DRIVE 18-key joystick for smooth, precise operation with all main controls within easy reach; joystick position fully adjustable via armrest settings; speed limiter controlled from joystick.
• 10-inch EASY TOUCH touchscreen with intuitive pictograms for in-cab control of tractor and implement functions; gives access to cruise control and hectare counter; many implement settings accessible via the touchscreen.
• Automatic recognition of PELLENC tools to facilitate configuration and use.
• Automatic parking brake that engages on stop and releases when the joystick is pushed forward; headland brake locks the inside rear wheel during tight turns (depending on model/options).

Powertrain & traction

• 156 HP DEUTZ engine compliant with Stage V emissions standard.
• Intelligent EASY POWER system automatically adjusts engine speed to implement demand, reducing fuel consumption and allowing engine operation at very low speeds (from around 1,600 rpm).
• Robust transmission with high gradeability (up to 40% depending on configuration) and TWINLOCK traction control system for optimum grip in difficult conditions.

Harvesting head & harvesting process (OPTIMUM 345 integrated head)

• Integrated harvesting head with advanced driving aids: soil detection to harvest grapes at the lowest point; low and high stops to automatically manage straddle height at row entry and exit; continuous visualization of straddle height and hopper level; ACTIV' row tracking to automatically align the harvesting head; road mode for transport.
• A fluid, intelligent harvesting circuit using two conveyor belts and trapezoidal conveyors to center the harvest; conveyor speed adjustable independently of tractor speed; blockage alarm for safe operation.
• SELECTIV'PROCESS 2 system (depending on model/options) for ultra-precise berry sorting with reported cleanliness up to 99.82% (French Institute of Vine and Wine reference).
• High throughput and handling: up to 50 tonnes per hectare at 4.5 km/h (depending on conditions and options); 1400 L hopper capacity with auger for complete filling and good crop distribution; hopper can be moved 60 cm to the rear for fast remote emptying.
• Harvesting head features for narrow vineyards: ACTIVITY automatic row tracking with feelers and in-cab guidance, three integrated fans to remove residual leaves (adjustable power and disengageable for cleaning), anti-clogging sensors and in-cab adjustable shaking.
• Fast, safe cleaning: unmatched wash time in approximately 30 minutes; washing function activatable from EASY TOUCH; retractable platform for secure access; remote opening of harvesting head components for cleaning and maintenance.
• Variable screen sorting table and full notched feed rollers to convey petioles to screen rollers, drop berries into the hopper and discharge waste to the outside; sorting and vacuum settings adjustable from the cab.

Modularity & tool carriers

• Great modularity with a wide choice of push and pull tool carriers, enabling soil maintenance, pruning, spraying and harvesting operations all year round.
• Automatic recognition of implements and easy configuration via EASY TOUCH.
