G'day all,
Just had the Mahindra mechanic from the next town over (the local dealer has stopped dealing Mahindras

) phone up to tell me that the roller pins holding the clutch fork in position had worked their way loose and this is why the clutch adjustment could not be made...all under warranty

.....the bad news I have to pay half delivery cost

...so thinking I might get the 250 hour service done whilst the tractor is there.
Thanks again for all the responses, this is a wonderful and supportive forum.
Cheers Darren
