YANMAR TILLER IDENTIFICATION

[REBELBOWTIE]

Good morning everyone. I'm new to the group and could use some help figuring out what model yanmar tiller I have. I recently acquired this tiller in a barter deal. It is missing a few parts, but they're not essential for operation. I knew I would have to fabricate some components in order for it to work with my quick hitch and function properly with my little Kubota BX23s. I have spent hours scouring the web looking at pictures, reading forums, and scratching my head while doing so. Not sure if its some kind of Frankenstein unit that was built from random parts or if it's some rare model that not many people have.

Some information that might help is that it is roughly 1400mm working width, has 35 tine mounting points, and is chain drive. Originally it was red and at some point was painted a grayish-green with a stenciled rattle can yanmar logo.

Any help would be greatly appreciated.

It's missing parts . . .

This was a 2-point rotary tiller converted to 3-point.
1400mm is very helpful. The 1400 will be in the model designation.

I'll have to study this one close enough and see if the YTOG has the manual for it.

I don't recognize that model. It's not the earlier, green, RS1400 that came original on many YM2000 tractors.

But I can tell you a little that may help you put it in service.

The unpainted flat plates are adapters to make it compatible with generic 3-point geometry. Because unmodified, raising the 3-point will bring the tiller into contact with the rear tires. I see holes in those plates where 3-point pins were likely installed.These plates locate the pins forward a few inches from where the original pins were located. The added adapter plates have a bolt into where the original pins were.

Yanmar used a unique 'bridge' in place of the usual top link. It had a short top link mounted to a hinge that was several inches back from the usual tractor top link location. This geometry made the tiller rotate back away from the tires as the 3-point was raised. Here's a post in an old tiller thread showing the unique Yanmar OEM 'bridge' top ink.

I modified a back blade in a manner similar to the modifications on your tiller, to make it compatible with my quick hitch. It now has a new pair of pins forward and slightly higher than the original pins. Here's my post describing this. It may give you some ideas for making your tiller usable.

I'm leaning towards an RS1404 model due to the certain top-link OE parts and the chain housing having the bottom protective kick plate. And this model has the lube port at the top too.

Exactly.

This update allows the PTO drive shaft to be longer than the short stubby one often seen with these Yanmar rotary tillers.

I have a hunch, this was reconditioned either at Fredricks or Southern Farm Equipment since you are in Georgia.

I think their preparation for resale, would include painting the adapters.

My theory is 'some farmer with a welder'. Who stopped at functional and rugged. ( BTDT )

Those tines seem unusually short.

More like rippers rather than tines.

Gear Drive I never found the need for the rear leveling wheels. Fredricks! Told it was doubtful I would need them. Last one they had at the time. New Tines Etc. 600 I believe.

Could those tines be for rocky soil? We used to have a tiller that had an extra set of tines (called pick tines?) for use in hard or rocky soils.

All the best, Peter

Rock hard clay soil is what I call it. The few Yrs. I used it I never noticed any Significant wear on the tines. The first turn was slow but afterward it was easy going! typical sears Walk behind was previously used. That could be true considering it was Org. used for tilling rice Patty's. Most of them you see have worn out tines. I believe you can get them still but tillers might be hard to come by. I was told mine was the last one and we had to go to a back warehouse and dig it out!!

Here is a shot of a pick tine doing work.

Here is a normal tine doing tilling work and the rear stabilizers making HILLS.

Hey, I found ANOTHER RS1404 ! I can confirm this is the model.

This is owned by a friend on the Mitsubishi-Satoh forum.

Here is one totally restored in Japan.

And the original tines,

I wonder if someone handy with a CNC plasma cutter could whip out some replacement pick tines to fill in the missing ones, or whole set as they look simpler than the paddy tines, to me at least.

All the best, Peter

Been Yrs. and thought I had the Tiller parts!! What I'm showing for Tines! Had to dig deep in the Yanmar folder.
TT-510 12mm LH. 510 RH.520 Tiller Tine Model 1400 & up.
TT-970 10mm LH.970 RH.980 Tiller Tine Model 1300 & Below
I have pretty much all the parts on the Tillers. Bearing, washer ,screws, Hard parts etc.

Sorry I haven't responded before now. Spent time with the family, then laid down with my granddaughter and we both got a week deserved nap.

I have read several threads on yanmar tillers on this forum and many others before joining. I plan to utilize some of the factory parts in my rebuild. Luckily in my job, I have access to metric tools and materials.

only thing I've figured out is that I haven't seen pictures of any others that have all of the extra brackets on the cross tube or ones that have mounts with rubber bushings supporting the center of the sheet metal top. That's what has been throwing me off. Thanks to all of the information I have been able to read through i knew it would be a 1400 series. The odd number of times had me scratching my head too.

I am already working on a design to replace the crude angle iron mounts for the bottom pins. Plan to remove the sheet metal and straighten out the bends and weld up the holes and cracks.

I watched a short video on YouTube where a guy had a yanmar tiller with these kind of tines on it. He even had some new replacements. I'll have to print out one of the pictures of the tine decals from one of the other threads. To help with installing new ones. I have noticed on some of my mounting points they are marked with an "R", I assume it means right

 

[careyo63]

The Vert. leveling handle RS 1200,1303 I thought it looked familiar. Those 2 models only. Idler bearing as in you Pic. 6207-2RS Tine Bar Idle end bearing.
