Yesterday I picked up a tiller for my YM2310. It is one of those reconditioned ones from Viet Nam. Probably as old as my tractor. I hooked it up today. By using the lowest hole in the ROPS for the top link and screwing the top link ends in as far as they would go I was able to get the top link connected. Connected this way the front edge of the tiller has only 1 inch clearance between itself and the rear tires. If the tires were new with the taller treads there would only be maybe 1/2 inch clearance.
The chaincase for the tiller is not quite vertical, the top is leaning forward a bit, maybe 1 inch more than the bottom. I don't know if that matters.
To make the drive shaft fit I will need to cut off about 4 1/2 inches. This will leave only about 3 inches of overlap because right now there is about 7 1/2 inches overlap.
Right now the tiller tines cannot be raised any more than about 1 1/2 inches above the ground. I can add more height to the right arm by screwing it farther together and the left arm by using the other, higher pin hole. I don't know if raising the tiller will bring the front edge closer to the tires, but I don't think it will. I'm just not sure how the geometry of the arms will move the tiller. Right now, with the tiller raised as high as it will go the front edge is about 4 inches below the tire center height.
Since the driveshaft is so short if I remove enough more length to make it possible to remove it with the tiller in place there would be no overlap left since it looks like about 3 inches would need to be removed.
So right now it looks like the drive shaft will need to be shortened and then it will need to be installed before the arms or the top link are in place. It seems odd that Yanmar would design an implement this way.
Right now I can see that with a shorter top link installed the top of the tiller will be able to be rotated closer to the tractor and hence the front edge will roll back away from the tires. This will tilt the chaincase more forward. I don't think this will be a problem because the front edge of the tiller will still be far from the ground. With the tiller sitting on the ground the front edge is 13 inches above the ground. It looks like the max tilling depth is 6 inches. Or maybe only 5. So the front edge could be tilted way forward, which would add clearance between the front edge and the tires as well as lengthen the driveshaft distance. I don't know though how much the tiller can be rotated forward.
I could also add length to either the tractor's lifting arms or weld a couple plates to the new to me tiller to locate the 3 point pins away from the tiller. This would mean that the driveshaft would not need to be shortened.
Thoughts anyone? I would really appreciate some advice. I thought buying a Yanmar tiller would mean that using it with my Yanmar tractor would be an easy thing to do.
Thanks,
Eric
