Yanmar YM2310 tiller problems

[careyo63]

Sent you a PM. On a tablet so make sure I sent it right.

I wonder if Motorcycle Warehouse received a random box of drivelines from the refurb factory and didn't know or care which length matched your tiller. The absence of the special top link components from their tillers might suggest this.

'Some Assembly Required!' (ie leave it to the buyer to figure out what's missing to hook it up).

I think they bought a bunch of drivelines from someone in the USA because they look new. The guy selling it said to just cut it down if too long. In any case I will not be able to use the driveline if I leave the tiller where it is because I would need to remove 5 inches from the 7 1/4 inch long sliding part, which would leave only 2 1/4 inches engagement. The U joints are so bulky and long compared to the original that I think they are actually made for much higher horsepower.

After making some adjustments to the lifting arm linkages and tilting the tiller so that the driveline splined shafts are parallel there is plenty of clearance between the tires and the tiller. The top link mount though is another small problem. The ROPS moved the top link hole 3 1/2 inches from the original location. Since I cannot find a shorter top link than the one I have I decided to shorten mine. To do this I removed 4 inches from the top link and 2 inches from each screw. Tomorrow I will TIG weld the top link back together. And order another to replace the one I cut up today. I am a recently retired self employed machinist. I haven't sold my shop or the contents and since it is about 400 feet from my house it is always available for making stuff. Nevertheless I would rather not modify stuff if I don't need to. I would rather spend the time doing something else, like tilling the drainfield. Or drilling holes with the post hole digger for planting cedar trees.

Thanks for the offer, I'll take it. After tilting the tiller forward to get the shafts parallel I measured the distance and your shortened shaft will work, plus there is plenty of room between the tiller and the tires. Now all I need to do is shorten the top link. If you send me a PM we can work out the shipping details.
Thanks Again,
Eric

Eric,

I've been poking around on one of my best hunt for Yanmar stuff on Japan sites. Yahoo.jp

So far this tends to be the closest candidate to your tiller. Since you are missing parts, it's the best I could align by all the pix you gave. It's sitting on a plastic gray pallet too.

If this is the MATCH to your tiller, I have a program that snags all the images off that page to save. This way, those highres images could assist you in finding the other parts or you can fab something like it.

That's the tiller I owned. Just in perfect condition. And if I needed a tiller for the YM2000 I would be looking into that model again. Worked really good. We had to dig it out of the back shop, Last one they had. Just came up what was in there. Tom's BA. Helicopter. Super cool..........

That tiller is almost identical. The only difference is that the two spring loaded rods that control the back flap are connected to two arms on mine that are missing from the pictured tiller. These arms bolt to the same plates as the H shaped tubular part does, but on the other side of the plates. You can see this in the pictures I posted. So really it is the same tiller, it's just that mine has these two extra parts. And mine is of course missing the wheel assembly. Thanks a bunch for finding the tiller.

Ah, good eye.

So, it's an RS1404-like tiller you have. Now the question is, is it a RS1504 instead? Those last 2 digits deal with how the tiller mounts to the tractor, the first two digits is the tiller series of sorts. The 14 & 15 often go hand-in-hand in the manuals. Sometimes a 16XX is tossed in the mix as well for even more confusion. haha

Oh, I did notice the REAR wheel assembly missing on your tiller. That is somewhat critical for leveling and to place a nice soil crease on the next lap of a pass to keep things uniform.

Now, on that RS1404, did you see another WHEEL? It's at the top of the unit. It's a spoke wheel for adjustments.

Also, in the images, did the tiller hookups look the same? same interfaces? If not, maybe an RS1402 is the match then. It's all tied in like that. Plus, the 14xx, 15xx 16xx all have various widths of the same tillers arrangement. The Yanmar tiller models can make a person dizzy.

I could just imagine what the tiller data base is like for Yanmar. Huge I'm sure....... Fredricks calls it a 5' RS1400 series.

Is that a 'plain' RS1400 with no other trailing letters? I may have that manual too. Do you need it?

 

[bmaverick]

On the Yanmar site is this PDF tiller manual. It's the OPs manual. In most applications, it would be VERY HELPFUL to those with the Gray Market tillers too.
https://www.yanmar.com/media/en_vn/2016/operationmanual/manual_RH170_RH190_en.pdf

Lots of good info on how these tillers work, how to make adjustments and to properly run them.

Eric, forgot or don't remember if I asked you this. Do you have an overrun clutch to run the tiller? Fredricks lists this in their catalog for tiller operation.

OR-660 Over-running clutch, quick disconnect 1-3/8” 6 spline X 1-3/8” 6 spline

Quit using it yrs. ago. Pic. I used on CL. when I sold it. Only ran a couple days literally. It was for My mothers garden back then. We went to the back and dug this one out. Wrong Dr shaft reflecks that. Which I kept the shortened one. And for the exact reason as for what just happened.

Answering a couple questions you asked. First, mine does not have the handwheel, but instead has a hand crank. All the tillers at the place where I bought mine had hand cranks. Maybe they all were broken off in Viet Nam. Second, I do not have an over running clutch. And I cannot put one on because there is not enough room. There is only 17 inches between the retaining pin grooves in the splined shafts. So that means there is only about 14 1/2 inches between the ends of the splined shafts. I do have an over running clutch on my Ford 9N tractor. I put it on after I used a Bush Hog for the first time. I am hoping there will not be that much inertia in the tiller, not enough to cause problems. If there is then I will need to make extension plates to space the tiller farther back.
Thanks,
Eric

That ORC. is Spring pin loaded. Mine is set by a pin you have to use a punch. PITA. not that easy to get to. That and the bolt on top link wasn't all that user friendly no doubt. I use the 2000 for a FM. so I have to use a ORC.. Used this setup for over a decade and still today. ORC. stays on now thank goodness or I would of had to of replaced it with a Quick pin... Look hard and it's down there!!

Really nice details of a RS1400A

It's really hard finding ANY images on the web for a Yanmar tiller in action and to use the rear hiller discs in the back the 'correct' way. This might be the best I've seen so far. Howbeit a Kabuta with a Yanmar modified RS1300. LOL

This is a huge time saver for gardeners. From beans, peas, carrots, turnips, potatoes and much more. Getting those tilled up hills in a perfect arrangement is priceless.

Only found an image of someone moving the Yanmar tiller back some with a 3PT hookup. Looks like a quick hitch setup too. Really Nice.

Now I'm getting drawn into the tiller strangeness!

I wonder if the guy in this picture (tiller painted orange - is that even a Yanmar tiller?) is doing it right. Seems to me the flat side of the wheels should be pushing the dirt into ridges. The way he has it, he's forcing dirt into the wheel bearings.

And - Carey's RS1400 is different from my RS1400 although both have the same RS1400 decal. His has the vertical rods, and three discrete hinges, for the back flap. On my RS1400 the flap is attached with a 'piano hinge', ie continuous all the way across. And chains down to the flap like in the photo just above this. (post #38). That photo shows the wheels mounted flat side out. When I tried that, they wouldn't track, they just left gouges at the outer edges of the tilled area. When I moved them to flat side in, like the tiller decal shows, they traced fine.

That is a Kubota tiller. I had the same exact one on the B7000 I used to have.

The gauge wheels are pointing the wrong way for some reason. Should be pointing backwards. Those wheels are what controls the depth on these style of tillers.

I don't really have a picture of it in action but here is one from the ad when I sold it.
