Looking good!
Here is the new machine... I finally picked it up today and broke it in on the way home. I cleared some snow with it on the way home at a friends place. This is a real pleasure to run. I have no regrets on not going green.

Being able to do multiple functions or not is controlled first by the method of plumbing the hydraulics. With a true 3rd function setup all three functions receive pressure or flow at the same time if activated. Action is only limited by the tractor's ability to provide gpm flow. JJ can correct me if I misquoted that.
As for my tractor, my FEL will curl and lift at the same time with little limitation of speed. When you add the 3rd function things slow down but still function. So if I'm picking up a Grapple full of loose brush for example, once in position, I push the button to close the Grapple and hold it, at the same time I curl the Grapple and lift the boom. All three functions are in operation and in one smooth move, without moving my hand from the joystick, I have a Grapple loaded with brush.
So you don't have to spring for the Cat 330, you just need the proper plumbing supported by adequate hydraulic flow.![]()
Yep Brian, I totally understand what you are saying. But,,,, with my 17gpm I am operating a LOT larger cylinders than the smaller FEL/tractor with say only 10gpm. So I'm not sure that my gpm is why it works better. My Brother's L3240 FEL probably takes less flow to do two functions than mine does to do one. So I eat up the tractor GPM difference real quick.
It works better because all three circuits are open to pressure/flow at the SAME time. The pressure/flow might be slower than if only running one function, but they still are functioning. So when I'm lifting and curling and at the same time operating my 3rd function, my Grapple Bucket is lifting, curling and tightening it's grip with the Grapple simultaneously. With a diverter setup that is not possible.
Are you saying you can add true factory style 3rd function to an M9540 for less than $600??[/QUOTE]
:thumbsup:No, up to 10-GPM. Over 10GPM needs a larger sub plate and the cost goes up $109. So it would be about $700 Maybe I'm wrong, but I am pretty sure that what some people are getting for 7-$800 with the 3/8" ports, these should not be rated for anything over 12-13GPM and those should not be used on anything bigger without taking a chance of cooking the oil. If a person runs their tractor hard, they really should have it set up properly, and that is not always done, even at the factory. (different story)
While you are absolutely correct about cylinder size, another thing to consider is ones ability to actually do all 3 functions at the same time evenly. I'm sure that what one is use to makes a huge difference with what their perception of speed is. What one person is used to working with at 25-30 GPM vs what another person is used to at 10GPM can be an enormous difference. Our 580 Case TLB uses the same size lift cylinders as my 7520. The 7520 feels like you are working at a snails pace.To me anyway.
