riber3 4 #1 Posted August 17 Hi everyone Not sure if I am in the right category here as I am trying to help someone with their small tractor. Its a Yanmar 1401 and the problem with it is the arms will not raise or lower. The PTO works fine and engages in all 3 positions I have attached some photos so you can see it and I have looked on line for a service and user manual. So far I have found a generic user manual for it and a parts catalogue in Chinese!! He told me he had changed the oil using a red HV46 which he says is the correct one for this model but he had not removed and cleaned the filter which I did today. Sadly it didn't make any difference and the arms still remain stuck in the Up Position. I tried altering the flow Valve and I can feel the Operating Lever Selector Spring when I push it forward for Up but not so much when I pull it back for Down. We have both tried pulling the arms down by hand but it appears seized or locked there. I am not sure if by removing the the top over plate would allow access to free it off? or if there is a safety override lock that needs resetting? So I would welcome any advice on how to fix it?

riber3 4 #2 Posted Tuesday at 02:41 AM I think I may have misnamed the part I have been writing about as I realise now that it is called the Rear End Loader Share this post Link to post Share on other sites
riber3 4 #3 Posted Wednesday at 02:25 PM I have done some further research and I think that the 3 point piston is jammed and is either rusted inside or a blockage. I cannot find a good diagram or photos of this and although some links have been posted referencing southern tractors when I click on them they just go to their homepage So if anyone has any photos or diagrams they could post I would be very grateful.
