Loader

[CBCGC1715]

I have a question if the loader on my new GC1715. Will it sag when resting for a period of time?

There was a big thread on this topic not too long ago that had people defending their positions. The general consensus is that it SHOULD not, but there is no guarantee it WILL not.

It's also good practice to make sure you lower it to the ground when shutting the machine off and leaving it unattended.

Thanks for the info. It makes sense to not have the loader suspended, but I just wasn't sure if the cylinders would allow fluids to flow when in the off position.

With the engine turned off there will be 'bleed down' of your suspended hydraulic implements such as the FEL (Front End Loader), 3PH (3 Point Hitch), backhoe, etc... Most of the time it will be unnoticeable for quite a period of time; a gradual lowering as there is no pressure from the hydraulic pump and the associated system to the cylinders.

This is normal.

If you experience a rapid lowering (with the engine turned off) then you are experiencing a problem.

My FEL does not sag. Nor does my 3-point. However - I lower both the grapple & rear blade to the ground. Takes the pressure off the seals and no danger of somebody getting hurt if either should sag or be accidentally lowered while playing on great grandpa's tractor.

The cylinders will NOT allow flow when off and valve in neutral.

IF it says, the VALVE is what's allowing fluid flow.

There are no seals in the valve. Just very tight tolerance steel spools in a cast iron bore. Not a guarantee 100% seal. Thus some leakage is possible.

Ive been around hydraulic equipment for a long time and with the exception of a few they all sag most of the time.

Depends on what you mean "period of time"
Some loaders have locking device,loader for Kubota L2800 located front of joy stick...and it works just fine.

Most of the "locking decives" including the ones on kubotas are just a manual lockout to prevent joystick movement. If the valve is leaking internally, it wont change a thing weather its "locked" or not

What he said. More important than the parking brake, unless you have no implements attached. :laughing:
