Picture this, you are selecting your tractor and know of more than half a dozen implements you would like to use. Your sales person asks, “How many hydraulics or remotes do you want?” This question may be answered by what those implements you have in mind.
Implements maybe attached to the front of the tractor, pulled by the draw bar or attached at the 3-point hitch while powered by the tractor’s PTO. Various implements require additional hydraulics to function. Implements such as loaders, grapples, mower decks, disk mowers, tedders, log splitters and more.
A tractor will have high-pressure hydraulic lines with remotes available for implements in the middle or rear of the tractor. The SCV is the Selective Control Valve which pressures the remote and designates how much flow is sent to those lines. The front or mid-mount SCVs power implements such as loaders and other implements. The rear SVCs control the movement of drawn implements or multi-functional PTO driven implements such as rotary cutters.
Remotes are the hydraulic couplers which enable you to plug in an implement with a hydraulic cylinder. This allows you to raise or lower and control the function of the implement using the hydraulic power of the tractor.
What kind of implements are powered by SCV remotes? Implements which require additional power and lift. Examples include front end loader, folding rakes, tedders, disc mowers, log splitters and more.
Double Acting Rear Remote – A double acting rear remote runs the cylinder in and out with pressure. Examples may include log splitters, grapples and backhoes.
Remote with Detent – Remotes with detent lock the valve open for continuous flow to run a hydraulic motor. Examples may include front mounted snow blower, rotary broom “street sweeper,” and sprayers equipped with a hydraulic pump.
Remote with Float – A remote with float positions the valve in neutral to allow the hydraulic function to move with the contour of the land. Examples may include back dragging a driveway with a loader or landing gear on drag type tillage equipment when the cylinders must follow the contour of the land allowing the implement to reach its maximum depth.
Why would you need dual remotes? Dual remotes may be used if an implement requires multiple movements or actions at once.
Most joysticks on a compact or utility tractor control the loader through a two-function valve. This operates the raising or lowering and tilt functions of the loader.
What is a third function valve? A third function occurs when another action is needed, and another cylinder is added. A third function valve is used on front-end loaders to operate hydraulic attachments. An example may be a grapple bucket which requires the two function, raise and lower plus tilt, as well as the ability to grab as a third function. Other implements may include hydraulic post hole diggers, snowblowers, debris buckets or round bale huggers.
So, when your sales person asks how many remotes you need you should be able to answer with confidence. Plus, knowing even if you decide later down the road that you need more, more remotes may be added.
