One of the largest and most powerful tractors we make, the 525 gives you more of what you expect from a Steiner. More power, thanks to a 28 horsepower Kubota liquid-cooled diesel engine. More features, including our full-time 4-wheel drive for superior traction and an articulated frame for unmatched maneuvering. More versatility, with your choice of more than two dozen Quick-Hitch attachments. And, more performance over the long haul, the result of our heavy-duty commitment to be the best.
