Other models utilized variations from Continental or in-house designs, including diesel options for models like the MH-55. Performance Performance: Massey-Harris 55 Diesel models typically produced around 50-60 PTO horsepower. The manual provides data for dyno testing and identifying power loss causes. Fuel System Fuel System: Carbureted gasoline/kerosene engines utilizing single or dual-barrel carburetors (e.g., Marvel-Schebler, Zenith). Diesel models feature injection pumps and injectors. Manual covers fuel pump, filter, carburetor rebuilds, and diesel injection timing. 🔧 Transmission Standard Standard: Sliding gear, constant mesh manual transmissions with typically 4 or 5 forward speeds and 1 reverse gear. Some models may have variations or auxiliary gearboxes. Optional Optional: Certain industrial versions or specialized models might have featured optional heavy-duty PTO clutches or extended range transmissions for specific tasks. The manual would cover any such variations. Features Features: Clutch type: Dry single-plate or dual-plate, depending on model and application. PTO speeds typically 540 RPM, some later models may have 540/1000 RPM options. Manual details clutch pedal free play adjustment. 📐 Dimensions Exterior Exterior: Massey-Harris 44 Wide Front tractor: Width approx. 72 inches. Row Crop (Narrow Front) versions would be significantly narrower, around 50-60 inches. Overall length often exceeding 120 inches. Manual provides exact wheelbase and track width settings. Interior Interior: Tractor operator station typically features a simple control layout, adjustable seat, and steering wheel. Manual covers dashboard instrumentation, control linkage adjustments, and seat mounting. Cargo Cargo: Not applicable for cargo in a traditional sense; focus is on tractor's operational capacity for implements and towing. Weights Weights: Massey-Harris 30 tractor typically weighed around 3,000 lbs. The MH-101, a high-utility row-crop tractor, would weigh significantly more, likely in the 5,000-6,000 lbs range. Manual provides detailed weight distribution and recommended ballast. 🛡️ Safety Features Ratings Ratings: Safety ratings for this era of tractors are not standardized in the modern sense.
