Binding Type Binding: Digital (Not Applicable) Paper Type Paper Type: Digital (Not Applicable) ⚙️ Engine Specifications Primary Engine Engine Family: Massey Harris/Perkins (common for later models and diesel variants). Diesel Variants: Model 44 Diesel explicitly mentioned, likely powered by a Perkins diesel engine (e.g., P3 or AD4.203). Gasoline Variants: Models 22, 30, 44 (non-diesel) would typically use gasoline or kerosene engines. Performance Horsepower Range: Varies significantly by model and engine. Early models around 30-40 PTO HP, later models up to 50+ PTO HP. Torque Characteristics: Designed for robust low-end torque suitable for agricultural applications. Fuel System Carburetion: Typically Zenith, Marvel-Schebler, or Rochester carburetors for gasoline/kerosene models. Diesel Injection: Indirect injection (pre-combustion chamber) typical for Perkins engines of the era. 🔧 Transmission Standard Type: Manual transaxle with multiple forward and reverse gears. Commonly a 4-speed or 5-speed gearbox. Optional Features: Live PTO (Power Take-Off) was a significant feature available on many of these models, allowing for continuous PTO operation independently of the clutch. Features Gear Reduction: Often featured a multi-stage final drive and differential for torque multiplication. 📐 Dimensions Exterior Wheelbase: Varies by model, but generally in the range of 75-85 inches. Length: Approximately 120-140 inches. Width: Approximately 70-80 inches (excluding implements). Weights Operating Weight: Typically 3,500 - 5,500 lbs, depending on configuration and engine. Drawbar Pull Capacity: Designed for substantial drawbar pull, estimated at 3,000-4,500 lbs. 🛡️ Safety Features Ratings Safety Standards: Reflects agricultural safety standards of the mid-20th century. Modern ROPS (Roll Over Protective Structures) and seatbelts were not standard. Active Features Braking System: Mechanical drum brakes, typically operated by foot pedals with a locking mechanism. Passive Features Operator Station: Basic platform with controls; no modern safety enclosures. 💡 Technology Features Infotainment Features: None. Designed for functional operation, not entertainment. Driver Assistance Features: None. Basic mechanical steering and braking systems. Connectivity Features: None. Purely mechanical and hydraulic systems. 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 40-60 operating hours or annually. Specific SAE viscosity grade recommended (e.g., SAE 30 or 10W-30 depending on climate). Transmission Oil Change: Every 500-1000 operating hours. Recommended fluid type would be GL-4 gear oil (e.g., 80W-90 or 85W-140). Hydraulic Fluid Change: Every 200-400 operating hours. Typically ISO VG 46 or equivalent tractor hydraulic fluid (THF). Fluid Specifications Engine Oil Type: API CD or earlier service classification for diesel engines; API SB/SC for gasoline engines. SAE 30 or 10W-30. Coolant Type: Ethylene glycol based coolant with corrosion inhibitors. Mix of 50% coolant and 50% distilled water. Grease Type: Lithium-based multipurpose grease (e.g., NLGI #2). Known Issues Common Wear Items: Clutch friction plates, brake linings, hydraulic pump...
