I think it is still a pretty impressive machine. The only bad part i have found is that it is not stable on hilly ground.
Parts and implements are not a really big problem here in Poland. There are still a lot of these iseki's artound, so some companies actually make and sell implements. In the 8 months i own these two iseki's i have acquired
- a 1 ton trailer to move stuff around
- a FEL
- a plough
- a kultywator (don't know the word for that)
- a rebak (don't know word, it's used to cut small trees into small pieces for burning)
- a tool to split bigger pieces of firewood (don't know name)
- a tiller like you have
At some moment i came across a guy who had an engine lying around, and wanted 100 euro for it. I instantly bought it, just to be covered on parts if needed.
About 3-point: you can lower the arms, but this would/should not be necessary. You need a few parts to connect the 3pt implements. Normally you can get this for about 100 dollars. If memory serves me well, frx55 managed to buy this in the US while rebuilding his tractor.
In Poland you can buy this on several places. Here is what the complete set looks like:
TUZ Kat 1 R zawiesia do ciągnikow Yanmar, Kubota, Iseki Rzeszow • OLX.pl
Hope this explains. Put some photo's of your tractor? Always nice to see the different states these things are, and what has been modified/altered during it's existence.
thx
