Thanks for coming back with the final chapter. We all learn!Dave,
First of all, you are correct on the loader model, it is an LA450S. I don't know why I typed that number. Sorry.
Thank you for all your time and explanations here, very valuable information. I printed it out to put in our manual.
Lugbolt had mentioned a flow control valve so we did some reading and searching and found a flow control valve for the loader which was stuck pretty bad almost closed and wouldn't turn, but with a little coaxing it did and now things seem to be working very well. The power beyond had actually stopped functioning and we couldn't angle the plow but after we opened the valve a little it's now working perfectly. The loader lift brings the plow up like it should. So that probably explains why the 3 point hitch was working fine but the loader wouldn't work. Man what an ordeal. Lets hope it stays working.
I appreciate all the input and time you guys spent on this.
Thanks,
Bill
Dave
