Help with 1500D tiller?

[rbeitz]

I have a 1500D and a Yanmar tiller. It seems that every time I run the tiller a little too deep or, when the tractor goes over some uneven ground the PTO shaft comes apart.

I am using the shaft that came with the tiller, I don't see how I could use one any longer or the tiller would not be able to be lifted up. Is something out of adjustment of do I just have to keep this thing running shallow? I'll try to get a picture posted to show you how it is set up.

Thanks,

That defiantly doesn’t sound right. Please post a pic. You shouldn’t have much more than 2 inches of take-up on the shaft total from top to bottom.

Ok here's one photo. You can see the shaft and the top link. The top link is adjustable, I just don't know if adjusting is what it needs.

Here's a view from the other side...

And one more view from the top...

Thanks in advance for any advice you can offer...

And one more pic to show what I've been doing with my tractor. We've put in a pond earlier this summer and just yesterday I started installing a big shrub bed as a backdrop to the pond. The tractor has been great for both of these projects except for every now and then when the pto shaft comes apart and I have to shut it down and put it back together.

Have you taken the driveshaft apart and inspected it? If one end, inner or outer, is a different length than the other, that will greatly reduce the distance it can expand when the tiller drops and collapse when the tiller is raised. If the lengths are equal and the shaft is near bottoming when the tiller is raised, then all you can do is shorten the top link and limit how far it can drop.

Norm, I hate to muddy the water here but are you saying that when you have to cut down an implement shaft that you should cut both the male and female ends so that both maintain apx. equal legnths? thanks, bw

The shafts are pretty close to equal lenth. I'll have to measure them to be sure. From my pictures does it look like I installed the top link correctly? I wasn't sure if that bracket went up or down? From looking at it I don't know that it would make a difference with this problem though.

Beautiful soil you get to work with. You have the wrong shaft for that tiller tractor combo. Sometimes Japan sends the wrong shaft with the tiller and sometimes the dealer finds one that will fit to replace a crappy one. I am worried you will do some serious long term damage to your PTO if that keeps coming apart. I have new shafts that will work and I am sure other dealers sell them also. Get a new shaft that is cut to fit if you can afford it.
