I have a x475 with a 3 bag collection system I can give you photos and measurements of. What do you need?

Much different set up....the x495 has what is called a click n go bracket to attach the bracket on an x475.....your Gx345 will not be like that.

I agree...not to mention the deck size would need to be the same for the power flow.

 

Deck size will be the same, both 54". By looking at pictures i'm confident that at least the chute will match up to my current powerflow. Or at least because the decks are the same size, the powerflows will likely by identical. Either way i'm curious about how it connects to the back of the tractor? My current 2-bag just slides in, pin on each side and a pin on the bottom in the hitch. How different is the connection with the 3-bag system? Can I purchase the click n go bracket to make it work on my GX345? or will I have to make a custom bracket. Its a pretty good deal that I don't want to pass up. Thanks!

 

They do sell a 3-bag for the GX345

In the description note, it does say "GT and GX Tractors require M146153 pin" I'm not sure if this is the click n go bracket your are referring to?

 

What you posted is for X500, X530, X540 etc tractors.............Not X475, X485, X495, X575, X585 and X595 like the power flow you are looking to use on your GX345.


Not sure if this will work or not.............Part # 15 is that part number you listed.

The silver lever and black metal part( is the click N go brackets) is what the bagger bracket slides into.

 

Definitely won't fit unless you make up your own mounting brackets. I have a 2 bin bagger on my GX345 and it is way different how it mounts compared to a x475. See picture that I attached.

 

Here in this listing is what the frame from an X475 looks like and you can see the 2 arms that come off the frame bracket and fit into the click n go brackets.............Your GX345 is not going to have that kind of set up for that Power flow system to work on your tractor.

Here was the best I could find of a 3 bag on a gx. The arms do look similar but is hard to see because the picture is small.

otherwise looks like I may be making a custom bracket....

 

I think the pictures of what you are buying is what we really need to see to help you know if maybe it will work for you or not.

 

The 2 and 3 bag hoppers are all the same.The lower part of the mounting bracket is what is different between models. Below the hopper top is 2 bolts which exchanges the mounting frames.
