What the 641 Workmaster is used for
The 641 is well suited to routine small-farm chores, light tillage, mowing, and use with Type I three-point implements. Its utility chassis and available loader make it a practical vintage working tractor.
Because the PTO is transmission-driven, it stops when the tractor stops. Plan PTO work accordingly, especially with mowers or other implements that carry momentum.
Why the Ford 641 Workmaster stands out
The 641 is the four-speed member of Ford's 601 Workmaster line, with position and draft control and a 1,250-lb Type I rear lift. It was available with gasoline, diesel, or LP-gas power, while power-assist steering was optional.
Buying a used Ford 641 Workmaster
Confirm the model and engine fuel type from the tractor itself, because the 601 series offered several closely related configurations. Test the PTO, three-point lift, transmission in every gear, and loader hydraulics if fitted; the serial number is on the transmission case at the top left behind the starter.
