I was looking for a s1lwb landrover with a PTO but they are going for funny money , and a friend said what about a unimog 3point linkage PTO better off road and better all round , may have a chance of one but its been lying for 10 years , ? What things should I be watching out for with on a old uinmog 406 and what things go wrong , parts hard to get ?. Thanks .I am up in Scotland
