1975 International Loader/Backhoe 3500A - Stopped Going Forward

I have read that the high pressure tubing could have bod o rings or are cracked. I have a full service manual that shows them but does not detail how to get to them while on the tractor. Everything from the manufacturer assumes the engine, trans or hydraulics are removed from the unit. Anyone have any guidance on getting to it? Also, and this is a DUMB question, but the floor comes out readily except for the differential locking pedal holding it down. Any ideas for clearing that? Thanks all...

The forward and reverse opperates on a flat serface? And some pipe fittings sliding on it just below the " bridge" between the floorboards. In my case there was a crack in those piping.
That oilpressure there worked in pilotpressure mode.
Remove that shiftcover and inspect those slidefittings for crackes.

Reverse works fine anywhere. Forward does not function - in fact it acts like its is still in reverse as the tires rotate backward - and the speed is appropriate to high or low. So it acts as if it is not out of reverse at all. Both forward and reverse did function when I got it though forward was not nearly as strong as reverse.
