Notes:The 60-inch rear mower required the three-point hitch and rear PTO. A PTO-driven 50-inch tiller, model 7-1261, was offered for the D-series tractors. The tiller required the three-point and PTO. In late 1977, Wheel Horse removed the Ark 550 loader and Brantly 617A backhoe from their list of approved attachments due to high axle failure rates and warranty claims.
