Good morning, in advance thank this forum, and facilitate both things to those who are mechanical and that due to circumstances we do not have to pull the manual. The problem I have is with a retro -velocation Massey Ferguson 50Hx S series of the year 92, the transmission does not work in front or behind, and the most beautiful thing is that there is no technical service throughout Andalusia, apologize for the tocho, I beg you to help me with the problem thank you.
