Hi The 1135 has an inspection cover, it has a greaser in it for the release bearing. a lot of other masseys have plates under the clutch housing, so don't see why not.
As the other poster said try it in gear and stand on the Brakes I have done this on a fordson that stuck and it worked for me Just make sure the stop works good, If not ya might need clean shorts L.O.L
Maybe the seals are leaking on the motor or transmission input and oil has stuck it too seen different colors do this once in a while. I remember an old guy telling me that blocking the pedal down for a long time is not a fantastic Idea as the springs are under a lot more tension and it weakens them over time. Good luck
