yanmar tiller

dirt clod · Oct 17, 2006

how well would one of these work on a kubota with a 540rpm. Was these tillers designed to work at the higher pto gears that yanmar has?
how does the quality compare to others?
Should there be a clutch or shear pin for this tiller?

I think yanmar tillers are of high quality . they were used on farms in japan. They may work with 540 pto but they may have been operated at higher pto speeds. Don't your kubota also have 1000 speed pto. I have seen a clutch used on tillers.

kubota has 540 rpm. I wonder if yanmar tiller would be geared too low?

kenmac · Oct 17, 2006

I thought that most tractors have 540 & 1000 pto speeds. I'am asking cause I don't know about all but, I see tractors advertised this way. My yanmar had 4 pto speeds 1 is around 540 I don't know what the others would b used 4 but would think tiller operation .
Some of the ones on here that sell these tillers could tell you if they will run correctly at 540.

I typically make the first couple of break up passes in 540 for the additional gear advantage. I then shift up to the higher speeds for a final pulverization. The tiller will work fine at slower speeds.

I have a 1202 (48" wide) Yanmar tiller on my Iseki, 19-hp motor, 16-hp PTO. I use the first two speeds out of four available, 540- (speed #1) and whatever the next one is (#2). It works well at these speeds in first and second gear, low range (but not creeper gear). I accidentally put the PTO in speed #4 (1000-rpm I think) and it lugged down the motor and really threw the dirt around. I think 1000-rpm is way too fast, for my soil and tractor anyway.

If you see pictures of Yanmars working in Japan you will see that they are tilling under water, in the rice paddies. Which means that they are just stirring up soft mud and can run at any speed.

I have a 1301 yanmar tiller , I run it at 540 and it dose good. I have never ran it any faster than that.

Could you post a pic of a tiller being used under water? Don't believe rice paddies are flooded during spring when being tilled and planted but I could be wrong. No way to get paddies leveled out as flat as are needed if you are still turning up mud soup.

Probably could, but I won't.

Well excuse us for wanting to see that

This is the first I knew that you wanted to see one, Eddie. If I happen to run across 1 again, I will post it. They were on the old "Sanko" site, but gone now. How about some water buffaloes tilling under water, if I see them again?

I downloaded this picture from the Yanmar-Japan corporate website, International section.

I think their point is that flooded rice paddies are one of the working environments their tractors are designed for.

Thanks California, that's one of them. I rest my case.

Give it a try. The tiller puts the most beautiful fluff in the soil. It brings all the fine soil to the top and totally buries the trash. I only do this after I've made a couple of passes at 540. On each pass I till a bit deeper until the tiller is reaching all the way down.

how deep do you till, if I go more than 6" the angle on the u-joint gets too steep and comes off. I'm just wondering if I've got the right set up.

LMTC · Oct 19, 2006

Anything more than 2-3" is counterproductive for gardens. If the hardpan below that really needs to be broken up, better to drag a subsoiler around and create some channels. Or run a chisel plow over the area if possible, or even disc a couple of times, but not to the point of fine silt. Tilling too deep brings up inert weed seeds to a level where they can germinate, allows the ground to pack more firmly when rained upon, creates greater potential for topsoil runoff, and a few other things.

Must be my eyes but I don't see a tiller on that tractor in the water. Come on guys, give it some thought, there is no need to till in a mud puddle. Why would Yanmar design and build all the auto controls, i.e. UFO control, for their tillers to maintain perfect depth control if being tilled in the mud. Bet some of you think cranberries are also grown in the water like rice.

Personally I till at least 6" deep. Have been doing so for more than 30 yrs. Ground conditions will have a big factor on ground prep. You do have the option of varying speed of the tiller and tractor to control how fine or course the soil is worked. Soil conditions vary greatly based on locale. On my tractor/tiller setup the angle of the PTO shaft isn't very steep at 6" depth but then I also have an adequately long PTO shaft.

Here's another mud tilling pic. Not with a yanmar but still tilling mud for a rice farm.

Actually I'm not sure if that's a tiller. It looks like he's tilling up something there anyways

I've seen farming identical to the second photo, in rural Hawaii.

From a distance it looked like an ordinary US tiller was being used - possibly with some extra width.
