Backhoe not working?

[319cssb]

I can lower (deploy) the backhoe, but none of the controls at the backhoe do anything. Is there an over ride switch that would prevent anything to work?
I can switch the RPM control to 2000RPM but nothing happens, neither on the driver side by the frame, nor the hi/low switch at the backhoe part will do anything. Does that switch have to work for the backhoe to do anything?
You guys expert advice is highly appreciated

Did you engage the PTO in the cab?

As Natrgatr said, make sure the PTO is engaged. To engage the PTO, move the lever to the rear with the clutch depressed. You can hear the PTO when engaged. Also, make certain you never drive the FLU419 with the PTO engaged or you will cause damage. The switch for increasing RPM on the rear only increases the RPM. The backhoe will function regardless which setting the switch is on. The backhoe will operate faster with the higher RPM.

Does the backhoe even deploy without the pto being engaged?

No

No

So yes my pto is engaged. In my first post I said how I can deploy the backhoe , but the levers back at the seat do nothing. Is there something I’m missing?

I figured out why the backhoe didn’t work!

Tell us!

Tell us!

Normally I’d let y’all guess. But this week I’m out of consolidation prices, so here it is.
The quick disconnect to the backhoe was disconnected. And the reason for that is a large split in the supply hose.

Got it working

Why would that be, with open center valves?
Besides, I've driven mine quite a bit with the PTO engaged, or the snow blower wouldn't have worked.

I think when they say not to drive it with the PTO engaged, they are talking highway speeds. On page 97 of TM 5-2420-224-10, under 'Moving The Vehicle', the manual states: 'PTO must be disengaged or pump will be damaged' before moving.

Not sure what vehicle speed would have to do with it. It really should be the engine rpm that counts.

Either way, as mentioned, I've spent many hours with the PTO engaged while driving at about 2,000 rpm. In First gear low range, but still.

I still have to see a flu419 move at highway speeds.
