Likely in the range of 400-600 lbs. Exact figure in manual.
Towing Capacity:
Towing capacity will be specified in the manual, typically designed for light-duty trailers.
Safety Features Overview:
As a tractor of its era, safety features were more basic, focusing on mechanical integrity and operator awareness. Modern safety standards do not apply.
Braking System Type:
Internal expanding shoe type, mechanically operated via brake pedal.
Parking Brake:
Mechanical parking brake system.
Operator Presence Control:
Likely includes a seat switch that disengages the engine or PTO if the operator leaves the seat.
