You have a problem with the forward clutch pack not engaging or it is slipping,engine stopped and equipment on the ground,brake set go under the machine in front of the L/H back wheel,look up and you will see the linkage for the shuttle control,check to see that it is intact,outside there you will see the clutch cut out solenoid,it is about the size of a coke can,it has a pigtail wires coming from it to a plug,disconnect the plug from the harness to eliminate the cut out clutch,with the oil level correct(it is checked with the engine on low idle)start up and see if it will go forward,if not a pressure check would be the next thing,you would need a 0 to 300psi gauge with a suitable fitting to screw into the test port which is on top of the unit near the breather,an Allen plug has to be removed, there is a concave spring in the forward clutch pack and if it cracks and loses its tension you lose the drive,there is a seal on the piston that engages the forward clutch should the seal fail the clutch pack will not be squeezed tight enough for it to drive,very little can be done with that shuttle in situ,when you have strong reverse you know that the torque convertor,charge pump and reverse clutch pack is ok,if that happened sudden I would suspect the concave spring.
