you don't have a local Jinma dealer?. then you have bought the wrong brand of tractor..Tried the local tractor dealer on the off-chance, nothing there, but wasn't expecting much.
Have ordered one from Oz.
Might try and bodge up a repair for an emergency spare.
At the edge of the world, we don't have the luxury of driving to the corner tractor shop, we make do with what we can.
