you have several options:
1) If you have the know how and tools, you can craft a 3rd port and rig it up - Surplus Center (
Surplus Center - Hydraulics, Engines, Electrical and More) has many of the parts you will need
2) Get a third port kit from New Holland (I have one of these on my 1630) but it is set up to give you hydraulic ports at the rear. You would then need to plumb (either with hose or SS tube { and hose connectors}) it to the front and either fix mount it to the tractor or flex mount it (so you can remove with loader) to the loader - here you will need connectors to the port-to-loader (like your other loader hoses) and loader to plow stuff
3) go to
Everything Attachments | Skid Steer Attachments, Tractor Attachments, 3 Point Hitch Attachments, and Farm Tractor Implements. and get their custom built 3rd function hydraulic kit with your tractor and loader model’s, $775, shipped within 1,000 miles of Newton, NC, 28658… Call or e-mail… Rick Rinehardt, Everything Attachments 866-581-5818 or 828-464-1200
I did the second - then realized had I known about option 3 - would have done that instead. The NH port is several hundred dollars and I would still have to do a lot of plumbing etc and then would still only have a port I ran off the side lever (next to the 3 pt hitch) - so when you get to steering, running the loader joy stick - you run out of hands when you get to the lever
I just ordered up the option 3 from rick ( Rick Rinehardt, Everything Attachments 866-581-5818 or 828-464-1200)
this gives me another (ie 4th) port as it will mount onto the 1630 and leave my rear remote alone and give me electric Hyd control in front (it comes with a new handle with an electric control for the remote)
Now I am using it for a grapple bucket and grapple fork (manure and trash pickup) - but I could use it for the Hyd of a snow plow
Hope this helps
