Picked this up from a buddy who works at local tractor/mower dealer/repair shop. He said a customer had them pick this mower up about 2 yrs ago because it stopped running while mowing. They determined it broke a rod, customer decided to buy a new one so they pushes this behind the shop. I got it for $250. I have determined 1 rod is broke and has a cracked hydro line, the oil filter is caked with stuff and was loose, I think they had leak and ran it low on oil.
It is a GH 620T with a 48" deck, also has an electric lift/level attachment on the deck.
I started removing parts last night to get ready to pull motor.

If anyone knows where the hydro release valve is, please let me know. It's currently released, but I have no clue where its at.

I have a Woods 6210 which is similar to yours ( made by Grasshopper) but I believe mine uses different hydro wheel motors. You should be looking for some kind of lever (dump valve) that twist and turn. Below is some information that may be of help.

Thanks for manuals, but different than mine.
I used and worked on a 721D at my old church, it had the double pump/motor setup like you probably have, this one is a single pump with dual drive motors. It says on the tag Parker so not sure what I got. My buddy believes it has a large hex nut on the bottom you turn which I can feel.
I found on GH website I can get a free manual using my serial number. I'm going to wait until Tuesday and see if I can get one.

EDIT: Quick search for the Parker part number and was able to download a complete service manual with rebuild instructions and specs. I guess this unit has no release on it which seems kind of strange.
Here is a pic of my linkage, no release lever anywhere on it.
