Question by: Duane R on Jul 27, 2025, 1:01 PM
pump says field reversible direction, how hard is that to actually do on something like a tractor or mower setup?
Answer by: Customer Support on Jul 29, 2025, 10:13 AM
Reversing the rotation on this pump is a mechanical adjustment you can make in the field without sending it back or ordering a different unit. That feature is built into the Series 26 design specifically so you can adapt it to different drive configurations without buying a separate pump for each application. For tractors and rotary mowers especially, this saves real time when you're swapping setups or replacing an older unit that spun the opposite direction.
