I wish my YM240 sounded all pretty like that. This YouTube vid is what they really sound like. (After this owner spends 40 seconds -unnecessary- playing with the thermostart).
CLANK CLANK CLANK RAP RAP RAP CLANK CLANK CLANK ... The sound is like a bunch of clowns hammering on a manhole cover with sledges. Everyone's first impression is that a rod is about to come through the block. No. They just sound like that.

Yep, aside from the near flaming thermostart, that's the sound! So far I've not had to use the thermalstart, this old tractor starts right up every time. I think the noise scared a lot of potential buyers off, the seller had it listed for nearly a month, the noise freaked me out too until I found out it's supposed to sound like that.

Yep thats the good things about them!!! They are reliable and really when you get down to it parts are about as cheap as tractor parts can be. That is the few things that you should need for one. I have only done an axle seal, volt reg, radiator, 3pt valve (these last 3 were under warrenty, from where i bought it), changed fluids, and rebuilt my hydraulic 3 point lift just to help the leak down and to just freshen the lift system up.
I also have added several hundred pounds of weight to the front bumper to help keep it down as well as added windshield washer fluid to my rear tires to get more weight on the tractor to help in pulling tractor for disking/plowing/blading.
These tractors were built to rototill in japan, they have a high HP to weight ratio, and they just dont weight much. Traction is often times your limiting factor when useing ground engageing implements, which is the reason i have all the weight on mine. To give you a comparisen the Old for N's were close to the same HP but they weighed almost 2x as much before they were even balasted, once balasted with water and wheel weights and bumper, they approach 2.4-3x the weight. the 8n could pull a 2 bottom plow, your lucky to pull a single bottom in most ground the size of the bottoms on the 8n. BUUUTTTT the N's were built for american farming with ground engageing equiptment. So they were heavy to get the power to the ground. Where even with the say 200lbs on my bumper and over 200+lbs of fluid in my rears i still will spin out pretty often if the disk gets too deep or the mower get caught on a high spot etc.

I start mine every day at least once and just listen to it idle, then I end up going back out to the garage to make sure I turned the key off and end up starting it up again...It's so ironic that the sound that almost made me pass on buying it is now music to my ears

The link from Nebraska Tractor Testing Laboratory is from the testing of a 1975 YM240 made for the American market, note the color, the external headlight location and the hood is hinged in the rear. The ad for the American marketing of the YM240 is from 1977 and shows the headlight located within the grill and the hood is hinged in the front. http://contentdm.unl.edu/cdm/singleitem/collection/tractor/id/1264/rec/16

look at all that rear wheel ballast! And those tires squatting. That sure is some weight, as California notes probably more than they say is manufacturer specs
(o is that 284??) this is so that they can actually put the power to the ground.

That linked picture from the Nebraska test is really interesting. I had never encountered that section before. Apparently the side steps are actually for passengers! It would also make climbing aboard MUCH easier.
My manual for the YM240 says no more than 310 lbs of added weight TOTAL, or 155 lbs per rear wheel. It also specifically says not to run liquid and cast iron ballast, but to choose one or the other. Additionally it says never to run liquid ballast in the front tires. Yanmar, whose representatives setup and operated the tractor, according to other commentary, gave their YM240 430 pounds of cast iron ballast PER WHEEL, and then tossed in another 136 lbs of liquid ballast in each tire as well.
They did follow their own requirement and didn't add liquid to the front tires, just 220 lbs of suitcase weights. It sums to 1355 lbs ballast added to the 1950 pound tractor, or a mere 825 lbs beyond what Yanmar specified in their manual. They went over the required maximum ballast by 42% of the tractor's starting weight, which is rather a lot to me. However, I have to say my YM2000 does much better with filled tires and 180 lbs of cast iron ballast per wheel....I understand why they did it, but I bet it wouldn't be much fun going up a steep grade.
