two options here:
1.) shift linkage (not likely)
remove the linkage and place in gear manually.
If it does not jump out, correct the linkage
2.) Transaxle. (most likely)
Replace from dealer $3K
Repair yourself 20 hours and $300 plus the usual blood letting.

John Deere recommends that you put Low Viscosity Hy-Gard or Hy-Gard Transmission oil in their Hydro or Gear Transmissions. The Low-Vis is used for factory fill in the Hydro and Hy-Gard in the Gear Transmission.

That is a GX85 gear-drive rear-engine rider. Manual should still be online. Deere will be glad to sell you one. I post some links below; worked for a Deere dealer for over seven years.
