Binding Type Binding Type: N/A (Digital Format) Paper Type Paper Type: N/A (Digital Format) ⚙️ Engine Specifications Primary Engine Engine Make Model: Typically powered by a diesel engine. Specific engine model (e.g., Allis Chalmers diesel variants) not detailed in product info but would be specific to the tractor configuration. Common engines for this class might include Perkins or Allis Chalmers' own diesel engines. Performance Estimated Horsepower Range: Horsepower would vary based on the specific engine installed, but likely in the 50-80 HP range for this size of utility tractor. (Specifics require engine model lookup). Fuel System Fuel Type: Diesel 🔧 Transmission Standard Transmission Type: Likely a manual transmission with multiple forward and reverse gears. Specific transmission models (e.g., constant mesh, synchromesh) and gear counts would be detailed in the catalog. Features Transmission Features: Durable heavy-duty design for agricultural and industrial use. May include a shuttle shift or power reverser option depending on configuration. 📐 Dimensions Weights Operating Weight Estimate: Operating weight would typically be in the range of 5,000 - 7,000 lbs (2,268 - 3,175 kg), depending on configuration and attachments. Specifics would require consulting a service manual or original specs. Cargo Loader Lift Capacity Estimate: Loader lift capacity would vary significantly based on the loader model and tractor configuration, but typically in the range of 2,000 - 4,000 lbs (907 - 1,814 kg). Forklift Lift Capacity Estimate: Forklift mast and carriage lift capacity would also vary, often rated for specific heights and load centers. Typically in the 2,000 - 3,000 lbs (907 - 1,361 kg) range for utility forklifts. 🛡️ Safety Features Active Features Operator Safety: Includes parts for essential safety features like brake systems, steering mechanisms, and control linkages.
