What Type Remote Hydraulics Do I Have?

4Papa · Jul 12, 2018

More out of curiosity than a pressing need is to know what type of rear remotes my machine (2015 TYM T1003C) came with. I have three remotes, #1 and #2 are spring-loaded forward and back and spring to center (neutral?) #3 is my mystery and I've not been sure it was operating correctly. The #3 lever in the cabin has FOUR detent positions. Center, Forward, Rear 1 and Rear 2. The Forward and Rear 1 positions lock in for continuous flow. Not sure what Rear 2 does. If I operate remote #3 with, say, a cylinder I use for my top link, it activates the cylinder until I pull it back further into the second detent and then it stops. Again, Forward to detent operates cylinder to limit until I manually return to center. Likewise, Rearward to the FIRST detent operates cylinder to limit until I return to center. Pull harder to 2nd detent and cylinder stops movement. Is this a float function? Is it a possible safety/panic position (as suggested by a diesel mechanic friend who tested the system)? Or is it broken? For most of my needs, remotes #1 and #2 are fine, but I use a 15' batwing that needs all three. My selling dealer has no clue. The owners manual only refers to the machine having three rear remotes, not what type they are. As I'm guessing the tractor came from the factory so configured, I have a call into the distributor who promises to get back to me. Still waiting. Any thoughts? Thanks.

With your top link connected assuming it does not have a check valve, put your #3 valve in it's extreme detent position and then go push and pull on the rod end. If you can move it in both directions, then you have a float feature with that valve.

As far as the other detent positions, I would have thought that they would have been self cancelling detents so that when the cylinder reaches the end of it's stroke in either direction that the valve would have kicked off automatically.

Does the #3 valve have any spring return to center action at all? As in if you mover the lever just a little bit in either direction from the center (closed) position does the lever go back to center on it's own?

Check it out and report back please.

Sometimes the SCVs as mentioned by Brian need adjustment to "return to center". Mine actually act differently depending on what attachment I'm using.

Same applies to "float" valves. They might need adjusting.

Top link cylinder does have a check valve. If the other detent positions are SCD, the valve is way out of adjustment as I blew a hydraulic hose when I first bought the tractor and it did not return to neutral. Ever since I've manually returned to neutral. There is no spring return to center at all and it takes some force to move it in and out of center to any of the detents. Not sure if the image I'm attaching of the rear remotes comes through.
#3 is to the left.

I've only used three attachments with #3, the aforementioned batwing, a land plane and a Herd seeder used to scatter salt-sand in winter. On none of the attachments has it ever returned to center automatically.

Detent valves can be used for hydraulic motors, spreaders, seeders, augers, hose reel etc. The float position can be used to allow to free wheel and be reeled out etc., or allow the item to slow down, instead of coming to an abrupt stop, which in some cases may cause rotors to bind or jam or spooling problems with hoses etc. Depending on the valve, if the detent is immediate, you may also be able to vary the flow rate. They can also provide constant flow to items that have their own controls such as post drivers, chippers etc.

Seems like if you have a flow detent and put the valve in that position with nothing attached to the valve, it'd trip a relief and you'd hear it. If it's float it would not.

Only relief I ever heard (and saw

) was when it blew a hose and spewed gallons of hydro fluid everywhere.

Hold the loader joystick in curl until the bucket stops. You'll be deadheadding then and the loader valve relief valve will open. On my old Kubota it was loud. On the current Branson it's quieter, maybe because the loader valve is remote. On the Branson the relief goes directly to the tank and not to the power beyond which supplies the SCV and 3pt. That is a common setup. When the loader valve relief is open those valves don't get much pressure. You can see if yours is like that by putting the loader in relief and simultaneously trying to raise the 3pt with a load on it.
