Finally got my 448hoe on the 3320!

My 448 will be here this wednesday along with my grapple bucket.
I'll be sure to ask the dealer if my pressure is where it should be as well. I'll post pic's when it arrives. happy digging /forums/images/graemlins/smile.gif

I had my dealer check the hydraulic pressure on my new 4520 with 448BH - it was right on the money, at 2500psi. I've been digging out some big rocks that have annoyed the brush hog for years, never felt any shortage of digging or lifting power.

The dealer did mention that although many folks ask them to crank up the relief bypass pressure beyond the factory specs, they won't do it due to warranty and liability issues.

Great looking setup!

You've got me wondering where my pressure is at...

</font><font color="blue" class="small">( Sometimes when I back into my hoe and lift it it does not go high enough to push the pins in. I then push the lift lever as far back as it will go and it lifts it that little extra that it needs. Try that and see if it works )</font>

I don't think that this is a pressure related issue. Usually it is the rockshaft height limiter set too low...
