Ford 445 backhoe no digging power

[Markhodges78]

Hello all again!! after spending much time working on this new to me machine fixing steering issues and fuel issues I have finally got to run the machine. What I have noticed is that the machine has no digging power at the backhoe. Once the bucket contacts the ground I have to move it back and forth to get it to dig then once the bucket is full It doesnt want to pick it up also if I try to push the dirt back in the hole with th the bucket by using the swing it doesnt have the power I can only move a little at a time off of the top by way of swinging . It does not bog the machine it just like Its not trying to do anything. So was just wondering what I should check.

Anyone have any Ideas ?

Have you checked your system pressure? That is always a good place to start.

 

[Markhodges78]

No I have not I do not know what tools are needed for this I have gauges to check transmission pressure on automobiles but nothing for tractor

If you have a local hydraulic supply company, they will have what you need. Something simple like this will work.



From what I can tell, your system should be producing 2500 PSI with a flow rate of 22 GPM. There might be a adjustable pressure relief valve that is set to low.

Note that using swing to move dirt is prohibited on most backhoes. But get a pressure gauge, and you'll know the story quickly (assuming your hydraulic fluid level is correct, as well.)

I checked around today at the tractor supply came up empty I知 going to call Napa auto tomorrow and see what they have

If the front load works good with weight and all, then you probably have some seals leaking. Agree do get a couple pressure gauges, and when in doubt about how much pressure use a gauge higher then needed

I would think the loader has a different pump than the backhoe. Could be something simple as a relief valve stuck open.

Have you changed the hudraulic filter and checked the suction screen?

Loader and hoe share the same pump. Start with the easy stuff. Quantity and quality of the hydraulic oil. Check for a Clean filter and screen. Proper system relief pressure. Proper pressure at the affected circuit(s). Assuming you have an original Ford backhoe attached to the 445 it should be a digging fool.
