Product Questions & Answers

Been running a Series 1 setup on a skid steer for a couple seasons now and looking to swap in a variable pump. This the same platform?

Yeah, the 3923-349 is built on the Series 1 platform, so you're already familiar with what you're working with. It's a variable displacement, closed circuit piston pump with clockwise rotation and a heavy-duty servo control configuration. Given your existing Series 1 experience, the architecture will feel familiar even if this unit brings additional control flexibility to the table.
