Product Questions & Answers (3)

Question by: Keith W on May 2, 2025, 6:14 PM
i got a machine that steers kinda touchy, is this one the non reaction style where the wheel dont kick back on you?
Answer by: Customer Support on May 4, 2025, 6:14 AM
Non-load reaction means steering feedback from the wheels is not sent back through the steering wheel the same way a load reaction unit would. This Series 3-6-12 unit is a non reaction load circuit, so it is aimed at steering setups where you want that reduced kickback feel.
Question by: Floyd F on Aug 8, 2025, 5:27 PM
What kind of equipment is this steering unit actually built for? Got a older forestry machine and trying to figure out if it'd even be worth looking into.
Answer by: Customer Support on Aug 9, 2025, 9:32 PM
Agricultural, forestry, construction, turf care, and industrial equipment are all listed applications for this unit, so a forestry machine fits right in that range. It runs a 17.90 cu in/rev displacement with a flow range of 4 to 8 GPM, which covers a solid spread of working equipment. The non-load reaction design means steering input from the wheels won't feed back through the wheel to the operator, which tends to be a practical choice on rougher terrain where you don't want the machine fighting your hands.
Question by: Warren B on Dec 15, 2025, 6:14 PM
Reckon this steering unit would work on my old tractor? It's been needing a replacement for ages.
Answer by: Customer Support on Dec 16, 2025, 6:45 PM
This Series 3-6-12 unit is suitable for agricultural equipment, forestry equipment, construction equipment, turf care equipment, and industrial equipment, making it a versatile option for various applications.
