You need one hydraulic remote for each implement function that must be controlled independently of the others. A double-acting function, such as a cylinder that is pushed both ways, uses one remote with two couplers; a single-acting function uses one remote and one coupler. The implement's operator's manual states how many remotes it needs, what type and whether any function needs float or continuous flow. If you have fewer remotes than it asks for, the options are a factory remote valve kit, a selector valve that shares one remote between functions, or a different implement, and each is confirmed with the manufacturers before anything is plumbed.
"The implement wants two remotes and I have one" is a fitment problem like any other. It has an answer in two documents, the implement's manual and your machine's manual, and it has a safety side that matters more than the convenience.
What a remote actually is
A rear remote is a control valve on the machine with couplers at the back, so that an implement's hydraulic cylinders or motors can be run from the seat. Summit Hydraulics, a vendor of remote valve kits, defines them this way: "Rear remotes are hydraulic quick connection points on the rear of your tractor that allow you to easily add and remove your hydraulic implements as needed" ("What are Tractor Rear Remotes?", modified March 27, 2024, read September 11, 2026). Makers use their own names, including selective control valve, SCV and remote valve.
Each remote is one valve section with one lever or control, and it runs one function at a time from that control. That is the whole counting rule.
How to count what your implement needs
List every movement the implement makes hydraulically, then ask two questions about each.
Does it need to move independently of the others? A blade that angles and tilts, a box blade with hydraulic rippers and a top-and-tilt setup that controls both the top link and a lift rod all have separate movements. If you need to adjust one while the other stays put, each needs its own remote, or a way of switching between them.
How is each one plumbed?
| Function type | What it looks like | Couplers per function |
|---|---|---|
| Double-acting cylinder | Two hoses; oil pushes it out and pushes it back | Two, on one remote |
| Single-acting cylinder | One hose; oil pushes it one way, weight or a spring returns it | One |
| Hydraulic motor | Two hoses, often plus a return or case drain line that the maker specifies | Per the implement manual |
| Float function | A cylinder that must follow the ground with no pressure holding it | One remote that has a float position |
Then add up. Two independent double-acting functions need two double-acting remotes, which means four couplers at the back of the machine.
Two details catch owners out.
- Float. Some implements need a remote that can be put into float so a cylinder follows the ground. Not every remote valve section has a float position. The implement manual says whether float is needed, and the machine's manual says which remotes offer it.
- Motors and continuous flow. A hydraulic motor needs continuous flow in the right direction and, often, a return route that the maker specifies. A remote that works a cylinder may not suit a motor. Treat any implement with a hydraulic motor as a question for both makers.
Flow: having enough remotes is not having enough oil
The count of remotes says how many functions you can control. It says nothing about whether the machine's pump can move them at the speed the implement expects. Summit Hydraulics' page says that "the amount of flow your machine is putting out will determine" what can be run, and that "the flow on your machine should only amount to 80% of the Max GPM rating of a valve." That is one vendor's guidance. Your machine's flow figure is in its specification sheet, and the implement's requirement is on its own.
Remotes also often share a pump with the steering, the three-point hitch and the loader, if fitted. Running several functions at once divides that supply. How your machine prioritizes it is set by its hydraulic design and stated in its manual.
The couplers still have to match
Having a remote does not mean the implement's hoses will connect to it. Couplers that look the same size can be built to different standards. The agricultural general-purpose standard is ISO 5675, adopted in the United States as ASABE/ISO 5675:2021, "Agricultural tractors and machinery – General purpose quick-action hydraulic couplers", which its ASABE abstract describes as defining interface dimensions and operating requirements for couplers that transfer hydraulic power from tractors to farm equipment, excluding brake circuits (read September 11, 2026). Our page on hydraulic quick coupler compatibility explains why ISO 5675 and ISO 7241 couplers of the same size do not connect, and why forcing them is dangerous.
What to do if you are short
Option 1: Add remote valves the manufacturer approves
Most makers offer rear remote kits for specific models and serial ranges. Some aftermarket makers offer kits too. Summit Hydraulics' page describes both, including a "power beyond" arrangement where flow passes from a loader valve's power beyond port to the rear remote valve inlet, and "universal kits" for open-center machines within a stated flow limit.
What decides whether a kit is right is your machine: open-center or closed-center hydraulics, how the existing valves are arranged, whether a loader valve is fitted and whether its power beyond port is available. These are per-model facts from the machine's manufacturer. Installing a remote valve kit is work for a dealer or a qualified hydraulic technician. It involves opening a pressurized system and changing how oil is routed to other functions, including the steering on many machines, and a mistake can affect more than the new remote.
Option 2: A selector valve on the implement side
A selector or diverter valve lets one remote run two functions, one at a time, by switching which cylinder receives the oil. It suits implements where you set one function, then the other, and never need both moving together. It does not suit implements where two movements must happen at once. Whether a selector valve suits a given implement, and which one, is a question for the implement maker.
Option 3: A different implement or configuration
Some implements are sold in versions with fewer hydraulic functions, such as a manual angle instead of hydraulic angle. If the implement maker offers one, it may be the most direct fit.
What not to do
Do not cross-connect functions, borrow the steering or loader circuit, block a return line or plug a motor into a circuit its maker did not approve. Each can overpressure a component or remove control of a function without warning.
The safety side: pressure and injection injuries
Hydraulic oil at working pressure can cause injuries that look minor and are not. Ohio State University Extension's fact sheet "Safe Use of Hydraulic Systems" (AEX-591.2.5, revised by Dee Jepsen, September 3, 2019, read September 11, 2026) states: "Pressurized fluid can penetrate the skin, requiring prompt surgical removal," and "Penetration injuries may not appear serious, but the injected body part is usually lost if medical attention in not promptly sought." It adds: "Keep hands and body away from pinholes and nozzles that eject fluid under high pressure," "Use a piece of cardboard or paper to search for leaks," "Always relieve hydraulic pressure before loosening hydraulic fittings," and "Never connect a low-pressure component to a high pressure components and vice versa."
The Farm and Ranch eXtension in Safety and Health community's "Hydraulic Safety" (2012, read September 11, 2026) says: "Injection injuries from high-pressure hydraulic fluid require immediate medical care," and "Always relieve the hydraulic pressure in an operating system before detaching or attaching a hydraulic line."
In practice: lower the implement to the ground, stop the engine, relieve pressure as your operator's manual describes, and only then connect or disconnect couplers. Never run a hand along a hose to find a leak. If oil is injected into skin, however small the wound looks, go to an emergency department at once and tell them it was a high-pressure hydraulic injection.
A cylinder also holds its load with oil. A raised implement or blade held up by a remote can come down if a hose is disconnected or fails. Lower it or block it before working near it.
Where you stop and confirm
Verify compatibility with the equipment manufacturer, the owner's manual, or a qualified equipment professional before installation or operation. For remotes that means the implement manual for how many and what type, and the machine's manual or dealer for what your machine has and can supply.
Stop and get that confirmation, rather than connecting or buying, if:
- The implement manual calls for more remotes, float, or continuous flow than your machine's manual shows it has.
- The implement has a hydraulic motor and you have not confirmed the return arrangement with its maker.
- The couplers on the implement do not connect to yours without force.
- Adding remotes would require changing the machine's valves, pump or lines. That is dealer or qualified technician work.
- A hose, fitting or coupler weeps, is cracked, kinked or abraded.
The honest limits of this page
We did not plumb or run an implement to write this, and this site does not test equipment. We publish no pump flow, pressure or remote count for any machine, because each belongs to that machine's specification for its serial range. Our guide to where the model and serial number are stamped helps you find the identification that specification is keyed to, and our overview of the seven checks behind farm equipment fitment puts hydraulics among the other checks.
Frequently asked questions
How many hydraulic remotes do I need for a top-and-tilt setup?
Two independent double-acting functions, one for the top link and one for the tilt, usually need two double-acting remotes, which is four couplers. Confirm with the kit maker's manual.
Can one remote run two cylinders?
One at a time, with a selector valve that switches between them, if the implement maker approves it. Not if both need to move together.
What is float on a remote?
A position that lets a cylinder move freely so an implement can follow the ground. Not every remote has it, and your machine's manual says which do.
Is it safe to add a remote valve kit myself?
Adding one means opening a pressurized system that may share oil with the steering. It is work for a dealer or a qualified hydraulic technician, using a kit the manufacturer approves for your model and serial range.
