Transmission Versatility: Choose Your Gears

The 311-B offers exceptional transmission flexibility to match any task.

Complementing this is the continuous rear PTO, operating at 540 RPM (1.375) from the engine, ensuring consistent power delivery for mowers, balers, and other PTO-driven machinery. The classic Eagle Hitch provides a secure and reliable connection point for your attachments.
