⚙️ Engine Specifications

Make:

Kubota

Model Series:

Likely a 3-cylinder indirect injection diesel engine from Kubota's D1005 or D1105 series (specific model number not provided but typical for this class).

Rated Engine Hp:

Approximately 29-30 PTO horsepower (engine horsepower will be slightly higher).

Bore X Stroke:

Typical for this engine series: ~78mm x 78.4mm (bore x stroke) for D1105.

Displacement:

Approximately 1.123 liters (1123 cc) for D1105.

Fuel Type:

Diesel

Injection Type:

Indirect Injection (IDI)

Governor Type:

Mechanical

Cooling Method:

Water-cooled

🔧 Transmission

Type:

GST (Glide Shift Technology) - Hydrostatic transmission with electronically controlled hydraulic pump and motor, offering infinite speed variation and range selection.

Transmission Options:

Likely a standard Synchro Shuttle or Gear Drive transmission was an option on some variants, but the L2959GST specifically denotes the GST gearbox.

Cruise Control:

GST transmissions often incorporate a cruise control function for maintaining set ground speed.

Range Selection:

Multiple speed ranges (e.g., Low, High) to optimize power and efficiency for different tasks.

Clutch Operation:

Pedal-based hydrostatic control, eliminating the need for a traditional clutch pedal for gear changes.

Transmission Fluid Type:

Kubota UDT (Universal Tractor Drive Oil) or equivalent GL-4 80W-90 gear oil/hydraulic fluid (refer to manual for exact specification).

Transmission Fluid Capacity:

Approximately 25-30 liters (specific capacity to be verified in manual).

📐 Dimensions

Overall Length:

Typically around 3-3.5 meters (10-11.5 feet), subject to configuration.

Overall Width:

Around 1.5-1.8 meters (5-6 feet), depending on tire size and stance.

Wheelbase:

Approximately 1.8-2.0 meters (6-6.5 feet).

Operating Weight:

Roughly 1200-1400 kg (2600-3100 lbs) without implements, depending on configuration.

Drawbar Pull Capacity:

Sufficient for its engine horsepower and weight class.

🛡️ Safety Features

Rollover Protection:

ROPS (Roll Over Protective Structure) is standard equipment on most Kubota tractors, including this model.

Parking Brake:

Mechanical parking brake integrated into the drivetrain.

Differential Lock:

Rear differential lock for enhanced traction in slippery conditions.

Seat Belt:

Seat belt typically provided for use with the ROPS.

Lighting:

Headlights, taillights, and turn signals for road use and operation in low light.

💡 Technology Features

Infotainment Features:

Basic operator controls, instrument panel with essential gauges (RPM, temperature, fuel, hours), and indicator lights. Advanced infotainment systems are not typical for this class of tractor.

Traction Control:

Achieved through the mechanical differential lock and the torque-sensing nature of the GST transmission.
