Well I bought my wife another Kubota.
1986 B7200 4wd hydrostatic w loader. Prior to purchase drove well no issues. After off loading at home, lifted tractor front end off ground w loader to check wheel bearings. Following this procedure hydrostatic pedal does not move tractor forward or in reverse. Checked hyd oil level {full} , made sure high low was not in nuetral , made sure 4wd lever was engaged as well as in two wheel drive.
The only differential was lifting front end of tractor by rolling bucket. loader works fine, PTO fine, 3 point fine, clutch fine, no linkage externally to come un hooked
What should be my next step. My other older Kubota are standard trans.
ASSISTANCE APPRECIATED, did I fry the fluid ?

Years ago I hopped off the Ford 1210 to do something. When I got back on, it wouldn't go. Long and embarrassing story, but turns out I must have bumped range selector so it wasn't in H or L - just in neutral :)

The range selector does not specifically HAVE to be in neutral. Any position other than engaged in gear is neutral. They may bump just a bit to not quite be in gear.

chim has it! Check if that lever at your right heel is somewhere BETWEEN the tortoise and the hare. Then pick one, It might take pressing the Fwd/rev/ pedal while actuating the range lever, to spin the transmission gears to get them to slide over one another.

Look up from the underside of the tunnel and make sure the drive shaft input to the hydro unit is turning. The tunnel cover can be removed to do the same inspection from above, but that takes tools and hand knobs ;-)

I own a DT not an HST but check to make sure the loader valve has gone back to neutral on both spools.
