The hydraulic motor will just stop turning when the load gets too heavy. In
an IVT the hydraulic motor is there only to control the speed, most of the
power will travel through the sungear. If the hydraulic would slow down the
tractor would still go forward...
Hydraulic motors works for small tractors like lawn tractors, but you can`t
plow with them. With the IVT you can.
