I’m interested to see if you get an answer.
Well then...here ya go:
"What you describe does sound like normal operation. Your remotes seem different from the models at your local store because you have both the backhoe and the third remote options. On your tractor:
• The A remote is continuous detent to power the backhoe.
• B remote is floating detent, which means it can be used like a spring center valve with light pressure, then when placed in the locked position it allows fluid to flow through the valve in either direction but does not apply pressure.
• The C remote is standard spring center or momentary.
The extra effort required to lock the B remote into floating position compared to the A is normal as the locking mechanisms are different."
I then asked if my B should lock in both positions. Answer: "No the B remote should only lock in one position."
We have our answer folks!
By the way, it took about 6 hours to get an official answer - fast!
So Gunny's tractor sounds like it's working correctly too since got neither the backhoe nor the 3rd rear remote.
