886 will not shift into  reverse. Tractor is rarely used.

Is the transmission differential locked up ? 
Does it shift into forward gears ?

I think it might be safe to say. The problem is between the shift knob and the reverse idler.

It will shift into all other gears and into park , but not reverse.

Does the shift lever go into the reverse slot?

The shift lever will go from park to the mid position but no further.

Simplest solution first would be dry or seized detent roller in the shift plate mechanism. Douse it down with lots of penetrating oil. I fought mine for a couple years, I'd pull the lever with one hand and hit it with the other to get it into reverse. At times when I would shift to park it would drag the high low linkage into high, so I'd be stuck in both park and high range at the same time. Started dismantling things expecting to have issues under the range cover, but after disconnecting the linkages it was obvious that all my problems were in the shifting plates. Got them lubed up good and it shifts like a dream.
