Would it self destruct if i plumbed a remote to the rear of my tractor that i could quick couple my backhoe hydraulics into and bypass using the pro mount hydraulic pump???? Any advice or ideas appreciated

You can do that but it's going to be much slower and have less power over a remote hydraulic pump.
If you do it flush all of the system out and use the same fluid as your tractor in it.

I thought since the pump had less gpm than the tractor it would make it more powerful to use the tractors hydraulic pump

Your tractor pump has to run other things like power steering, hydrostatic transmission, etc. If the pump were strong enough Kubota probably would have matched a backhoe with no secondary pump in it. Look at the B26, L47, M62...they all have internal pumps for the backhoe. Could be wrong but I think the M62 had 2 pumps.

It might be, and if so you'll be fine.

If the tractor pump produces more flow and the same or greater pressure as the PTO pump it will work just as well if not better than the PTO pump. You need to know those numbers.

The BL4590 had a factory 5 GPM pump and the L3650 has a 7.8 GPM main pump.
So you'll have enough flow.

I believe I’ll leave it alone designed that way to begin with. I’ll plum it in if my secondary pump on my backhoe fails

The L48 TLB actually has 3 hyd. pumps

Wolf man my l3650 needs a wiring harness but I’m having trouble finding stuff for it do you have any suggestions?
I've been able to find plug end sets on eBay and amazon in the past.
I'll look and see if I can find the listings.
And you can get all the right size and color wiring on ebay too.

Give me a few more days, I haven't gotten a chance to look at all my notes on these.
