Common diesel options included the Allis-Chalmers 4-cylinder direct injection diesel. Engine Displacement Diesel: Typically around 250-270 cubic inches (e.g., 4.3-4.4 Liters for the 4.25-inch bore diesel). Performance Horsepower Diesel: Rated PTO horsepower often in the range of 50-60 HP, with drawbar horsepower slightly lower. Torque Diesel: Torque figures varied with engine tune, but generally provided strong pulling power for its class. Fuel System Fuel System Diesel: Roosamaster, CAV, or similar inline injection pumps with individual injectors. Carbureted gasoline engines also existed. Fuel Type: Diesel fuel (for diesel variants), Gasoline (for gasoline variants). Lubrication System Oil Type Recommendation: API CD or CE rated diesel engine oil, viscosity grade like 15W-40 or 10W-30 depending on operating temperature. Consult manual for specific viscosity. Cooling System Coolant Type: Ethylene glycol based antifreeze mixed with distilled water (50/50 ratio typically). Check manual for specific additive requirements. 🔧 Transmission Standard Transmission Type: Constant mesh, spur-gear type transmission with multiple forward and reverse gears. Common configurations included 6-speed forward and 2-speed reverse. Optional Optional Features: Possible option of a 'Shuttle-Shift' or range transmission for easier directional changes. Features Transmission Fluid: Typically used API GL-4 or GL-5 gear oil (e.g., 80W-90) for the transmission and differential. Check manual for exact specification and capacity. Clutch Type: Dry single-plate or dual-plate clutch, depending on specific D-19 model variant. 📐 Dimensions Exterior Overall Length: Variable based on configuration, but typically in the range of 125-140 inches (317-355 cm). Wheelbase: Standard wheelbase around 80-84 inches (203-213 cm). Weights Operating Weight: Typically in the range of 5,000-6,000 lbs (2268-2722 kg) without ballast. Front Tire Size: Commonly 6.00-16 or 7.50-16 bias ply tires. Rear Tire Size: Commonly 14.9-28, 15.5-38, or 16.9-30 bias ply tires. Wheel Bolt Pattern: Typically 6-stud hubs with a 5.5 or 6.0 inch bolt circle. 🛡️ Safety Features Ratings Safety Ratings: Tractor safety standards of the era did not involve formal crash ratings like modern automobiles. Emphasis was on operator stability and roll-over protection (ROPS), if...
