[RgP454]

Hydrostatic transmission stopped Add new hydraulic oil gave to me by new holland dealer drove it about 100 yards and just stopped moving loader still working HST forward peddle wants to stay down to the floor it will return if I push reverse peddle but reverse doesn’t work either

I have a Kubota HST with a three speed transmission. If one of the gears is not engaged it will not move. There is a dead or neutral area between each gear, very easy to think you're in gear when you're not. You may wish to investigate that possibility on your tractor.

@RgP454 - I wondering if this is just a coincidence as far as adding Hydraulic fluid...

The first thing I would check is the Trans Pivot Assembly under the right side of the tractor it attaches the pedals to the trans... (it is in the picture below)... They sometimes break at the welds & will cause the condition you are describing...
