Last Updated: June 2024

Overview

The AGCO ST45, powered by an Iseki 4-cylinder diesel engine, serves a range of agricultural needs with its versatile transmission and tire options. The engine features liquid cooling, glow plug pre-heating, and indirect injection, allowing for a smooth operation with a gross power output of 44.2 horsepower and a peak torque of 139 lb-ft at 1500 rpm. It comes with multiple transmission setups including mechanical shuttle, power shuttle, and hydrostatic, all providing 16 forward and reverse gears, except for the hydrostatic which offers an infinite range within its four ranges. Standard agricultural tires are sized at 9.5-16 in the front and 13.6-28 at the rear, with optional turf tires for different tasks around the farm or estate. With a wheelbase of 78.9 inches and a shipping weight of 4448 lbs, the ST45 balances maneuverability with a solid presence on the field. Its dimensions enable it to operate effectively in various settings, while the potential maximum weight of 6000 lbs assures robust performance in heavier-duty operations. A Category I three-point hitch at the rear enhances its utility. The ST45 is designed with the user in mind, featuring a roll-over protection structure (ROPS), a 12-volt electric starter, and a hydraulic system operating at 5.2 gallons per minute with a 2485 psi pressure, ensuring a responsive and safe experience.
