Hello jc7622. That is just a great tractor. What did you think of the test drive? The 5740 has so much to offer with excellent quality and affordability. I just love that tractor.
In any case, the hydraulics can be done easily and a couple of ways. One way is to just run off the remotes. Another way would be to tap into the system and run quick connects to the front loader. Have a single spool valve by the existing control valve and it works great. The dealer should be able to set you up.
Also, talk to your dealer as Montana now has grapples available for that loader. The prices are pretty good and your dealer should be able to get the info on that for you.
Good Luck,
Maka
