Well we've been through the hoops with our first attempt at hay making this year.
We bought an old international harvester finger cutter - probably late 1950's - then a beaten up, rusted solid Lely hayzip, and a Bamford BL 58 for our equipment.
The finger cutter cut for 50 yards before the rivets holding the clamp for the blade disintegrated - we managed to source some, hit it with a big hammer and got the cutting done
Then came the hayzip - we'd stripped it down completely and then rebuilt after de-solidifying the rust etc and giving it a coat of pain, replacing some of the tines and re-welding bits, oh and having to sort out an extension for the PTO. So, set of spreading and everything going fine until a couple of the struts broke - so a re-weld was required, then off again. Managed a couple of sets of spreading and mounding up for drying which was great - then the UJ on the PTO end broke and sheared the yoke for the shaft - off to the local agric merchants for a new bit (was more expensive than the whole hayzip!) but got it going again so all was hunky dory
So - now to the baling. We'd made sure all greasing had been done, the chains were correct tension, new drive belt purchased and our neighbour (who used to have one many moons ago) had helped us set it up so all looked positive

Got going along the first row and the pickup looked fine, making all the right noises, moving along nicely and the first bale plopped out
Carried on up the row ok but after another couple of bales started to get a bad knocking and slipping happening - so all shut down to investigate - the UJ at the flywheel end was worse for wear so we thought that was the rpoblem. Off the agric merchant again and managed to get a UJ to fit, back to the field, fitted the UJ and started again - but the knocking and slipping much worse
We traced it to the bearing in the clutch mechanism - it had disintegrated

In retrospect we think the spring nuts on the clutch plate had been screwed down so far that it seems like the issue had been brewing for some time previous to our possession of the baler - the clutch plate had been screwed donw so far that no slippage was possible so any slip that was needed came from the bearing - over time this has taken its toll and it broke
So now its Fri evening - agric parts place not open til Mon - not sure if we'll be able to source a part anyway - but the rain is on its way
We have got 5 bales though
