TractorByNet.com was started by Muhammad Chishti in March of 1998. In the first week, approximately 20 members visited. By the end of 1998, some 300 members had joined and the rest is, as they say, history. Today, TractorByNet.com is visited by more than 500,000 people per month and has more than 141,000 registered members. Not only is the TractorByNet.com audience the largest of any tractor website, but the discussion forums are the most popular with more than 1.9 million posts.
