The UTB/Universal 445 is a utility tractor produced in Brașov, Romania, between 1972 and 1976. Designed for general agricultural tasks, this model served as a versatile machine within the utility segment, incorporating a 3-cylinder diesel engine and robust mechanical components.
Engine and Performance
The tractor is powered by a 2.3-liter (143 ci) 3-cylinder liquid-cooled diesel engine. It utilizes direct injection and an oil-bath air cleaner, delivering 45 hp (33.6 kW) at a rated speed of 2400 RPM. The compression ratio is 17:1, and the system includes a thermostart pre-heating aid for cold-start reliability.

Both options utilize a 254mm dry disc clutch. The drivetrain features a mechanical rear differential lock to improve traction in field conditions.
Hydraulics and Hitch
The machine employs an open-center hydraulic system capable of 2133 psi (147.1 bar) of pressure with a pump flow rate of 5.75 gpm (21.8 lpm). The rear hitch is a Category II/I type, equipped with both position and draft control, providing a rear lift capacity of 2660 lbs (1206 kg).
PTO and Operator Station
The rear PTO operates at 540 RPM, engaged via a dual-stage clutch to allow for live PTO functionality. The operator station is an open design, featuring manual steering with optional power assistance and independent contracting band brakes for stopping control.
