This tractor isn't just powerful; it's built to last and designed for the operator. With a substantial wheelbase of 118 inches (299 cm) and a length of 195 inches (495 cm), the A-80B offers excellent stability. The generous ground clearance of 14 inches (35 cm) ensures it can handle uneven terrain with ease. While featuring an open operator station for clear visibility, an optional air-conditioned cab was available, transforming long workdays into more comfortable experiences.

Hydraulic Muscle for All Your Implements

Powering your attachments is crucial, and the A-80B delivers with a hydraulic pump flow of 20 gpm (75.7 lpm). This impressive flow rate ensures that your implements, whether it's a loader, mower, or baler, operate efficiently and respond promptly, maximizing your productivity throughout the season.
