@sumarac7805 under load you mean that you have weight on the machine or when you "load"/rev the engine it moves slowly? Had known problems when I bought my machine with the drive and it needed a new drive pump. A valve block on the drive pump could cause issues and could borrow a good one and test that but was more serious with broken stuff inside causing my issues but it was the same with or without weight on it. Good luck sorting it out.
Do you have the manual for the machine? In that there should be info how to measure pressure for the drive system. I bought a quite cheap digital pressure gauge to be able to check pressures. The test outlets are MINIMESS type (at least on my machines. Not sure they have used that style on all years and models.
