YM1301D 3pt Upper Link Mount

Yeah,
I really lucked out on this deck. It was very little used. I also got a YMM-60, 5' belly mower which was original equipment for a YM195 and YM240. It had never even been mounted on a tractor.

we use the top four threaded holes and it is plenty strong, we mount a solid half inch plate and weld our brackets to that. I have a backhoe hanging form mine at home that I never take off and it shows no sign of fatigue. All of the P model Shibaura’s have the same exact hole pattern and come with the top bracket bolted on the four holes.

Greg,
Here are some pics of the mount. Sounds similar to what Buck fabricates.

Jim,
Thanks, but those photos don't look like they are of a 1301 or 1401. It looks like you just welded some almost square pieces to an existing plate that goes forward to the seat. It looks like it has the end plate already on with the slot for the chain used to lock the tiller in the up position.

Based on Buck's reply, I'll just plan to use the 6 threaded holes on the back of the tractor. Two are down in the main transmission casing, the top 4 are in the 3pt hydraulic housing that is bolted to the top of the transmission. Buck believes that to be strong enough - and I trust his judgment.

Thanks Buck and Jim.

Greg,
These pics are of a 1401d. All the 1041d & 1510d's I have sold have this configuration. We put 3 pts on all 1401's & 1510's. I'd like to see pics of Buck's config. Improvements are always welcome.

Jim,
Then it appears that the 1401 and 1301 are NOT the same. It you look at the photo of the back of my 1301D that I attached to my original post, you'll see that it looks different from the photo you attached. I don't have the plate with the hook for the chain.

There are many different combinations on the same model. I do the top link bracket both ways depending on the design. One welded to the seat bracket and one bolted to the housing. The most important thing for the bolted design is to use an oxidation inhibitor (copper or the like) agent on the threads so you can remove them down the road and keep the bolts tight so the plate can’t move. There was a post a while back about that very thing happening because the bolts had come loose and the plate could gain leverage on the bolts and tear them loose. If I can remember in the daylight to take a picture I will post it

Greg,

Checked out my Ym135 last night, the top link plate picks up four holes on the housing and the housing is aluminum.

I believe it is a factory setup and it works fine. Hope this helps!

I discovered much to my surprise that the transmission/transaxle housing is also aluminum. So even the two lower holes are in aluminum. I think I'll go the extra yard and make a plate to go under the seat and attach to the top edge of the bracket. That plate will catch 4 more bolts, and should make it plenty strong.
