Binding Type Binding: Likely saddle-stitched or perfect bound for durability. Paper Type Paper Type: Durable, likely coated or semi-gloss paper to resist dirt and moisture. ⚙️ Engine Specifications Primary Engine Tc21Da Engine Model: Likely a Mitsubishi S3L2-D or similar Yanmar-based diesel. Tc24Da Engine Model: Likely a Mitsubishi S4L2-D or similar Yanmar-based diesel. Performance Tc21Da Engine Power Gross: Approximately 20-21 engine horsepower. Tc24Da Engine Power Gross: Approximately 23-24 engine horsepower. Fuel System Fuel Type: Diesel Fuel Injection System: Indirect Injection (IDI) or Direct Injection (DI) depending on specific engine variant. 🔧 Transmission Standard Transmission Type: Hydrostatic Transmission (HST) Drive Modes: Two speed ranges (e.g., High/Low) typically controlled by a selector lever. Features Control Method: Foot pedals for forward and reverse speed control (e.g., treadle pedal system). Pto Engagement: Independent PTO engagement via a clutch lever, allowing PTO operation without moving the tractor. 📐 Dimensions Exterior Overall Length: Varies, but typically around 10-11 feet (3.0-3.4 meters) without implements. Overall Width: Varies, often around 4-5 feet (1.2-1.5 meters) depending on tire fitment. Weights Operating Weight: Approximately 1500-1800 lbs (680-816 kg) depending on configuration and fluid levels. 🛡️ Safety Features Ratings Rops Standard: ROPS (Roll-Over Protective Structure) is a standard safety feature for operator protection. Active Features Seat Safety Switch: Engine will typically shut off if operator leaves the seat while PTO or transmission is engaged. Parking Brake: Integrated parking brake system for secure stationary holding. Passive Features Lighting: Standard headlights, taillights, and brake lights for visibility. Operator Station Design: Ergonomic controls and a clear view of the work area. 💡 Technology Features Infotainment Infotainment System: Basic functionality focused on tractor operation; no advanced infotainment systems expected. Driver Assistance Driver Assistance Features: None in the modern sense; safety is primarily mechanical and through operator awareness. Connectivity Connectivity Options: No onboard connectivity features like Bluetooth or Wi-Fi. Primarily mechanical and electrical controls. 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 50 or 100 operating hours, or annually. Refer to manual for exact interval. Fuel Filter Replacement: Generally recommended every 200-250 operating hours or annually, or as needed if fuel quality is suspect. Air Filter Inspection Replacement: Inspect frequently based on operating conditions (dusty environments require more frequent checks), replace as needed. Fluid Specifications Engine Oil Type: API Service Category CD or higher, SAE 10W-30 or 15W-40 typically recommended depending on ambient temperature. Hydraulic Transmission Fluid: New Holland high-quality hydraulic/hydrostatic fluid (e.g., NH 410B) or an equivalent UTF (Universal Tractor Transmission Fluid) meeting specific NH specifications. Coolant Type: Ethylene glycol based antifreeze coolant, typically a 50/50 mixture with distilled water. Known Issues Common Wear Items: Hydraulic pump efficiency, PTO clutch wear, and fuel injector longevity can be maintenance-sensitive. Electrical Connections: Corrosion on electrical connectors can lead to intermittent issues in older units. 📚 Vehicle History Brand Heritage Brand Origin: New Holland Agriculture is a global brand with a long history in agricultural machinery, originating from Italy and now part of CNH Industrial.
