Japanese farmers who buy new tractors don't have to pay property taxes on their tractors until the fifth or sixth year after they acquire them. After that, the taxes get progressively higher each year until it becomes more economical to trade the tractors than to keep them.  Many of these tractors are used only for tillage in rice paddies and the seasonal nature of this work means that 15-20-year-old tractors often have very low hours of operation. There is an abundance of good, used tractors available in Japan at very attractive prices.

Some of these tractors are loaded into shipping containers--up to sixteen at a time, depending on size--and shipped to Vietnam or the United States for reconditioning. Reconditioning may include the engine, transmission, clutch, steering, brakes, hydraulic system and electrical system, along with new tires, a new seat, new paint, and replacement of filter and fluids.

Grey-market tractors include Yanmar, Mitsubishi, Iseki, Kubota, Shibaura, Shabiro, Hinomoto, Suzuki, Jen-Noh, Satoh, and Ford (Great Britain). EPA rules only permit the import of noncompliant emissions-standards tractors built prior to 1996; therefore, with each passing year, available tractors are that much older, and this will eventually spell the end of gray-market tractors. Also, increasing numbers of new Chinese-built tractors are being imported and sold at prices competitive with grey-market tractors. Grey-market tractors are often available at one-third the price of similar-sized new tractors such as John Deere, Kubota, and New Holland.

The biggest disadvantage of grey-market tractors is that they lack safety features required of new tractors sold in the United States, such as Rollover-Protective-Structures (ROPS), seatbelts, power-take-off (PTO) shields and guards, over-running clutches, and safety switches to prevent the tractors being started in gear.

There are other disadvantages. Pulling on the throttle of a grey-market tractor will cause it to accelerate, which is the reverse of tractors sold in the U.S. Grey-market tractors have multiple PTO speeds for operating equipment, whereas tractors designed for the U.S. market usually have only one speed--540 RPM--or possibly two--540 RPM and 1,000 RPM. Operators manuals, service manuals, and parts manuals may be written in a foreign language--usually Japanese--and aren't available in English.  Also, labels and decals on the tractors are usually in a foregin language.

As a result of these safety issues and in order to protect company trademarks and reputations, United States dealers do not sell or service grey-market tractors and will not knowingly supply parts. Also, the companies which built the tractors will not provide warranties; although, the importing firms may.

Replacement parts may be difficult to acquire; although, parts for most grey-market tractors are now available from sources across the United States and are readily located through importers, dealers, or the Internet.

Grey-market tractors generally have low-maintenance diesel engines which are durable, simple, and fuel-efficient. Japanese tractor manufacturers have the reputation of making the best compact tractors in the world. Many of these companies build compact tractors for well-known U.S. companies. Yanmar manufactures tractors for John Deere, Mitsubishi makes Cub Cadet and small Case-IH tractors, Iseki builds tractors for Massey-Ferguson, Shibaura produces tractors for Ford/New Holland, and Ninomoto made tractors for Massey-Ferguson and Allis Chalmers/Dutz Allis. A properly-maintained Japanese diesel tractor can have a realistic service life of 10,000 hours. Considering that many of the purchasers of these small tractors in the United States use them approximately 50-100 hours per year on small acreages, it is likely that most of the tractors will outlast their owners.


The Yamaoka Hatsudoki Kosakusho Engine Manufacturing Company was founded in 1912 by Magokichi Yamaoka in Osaka, Japan. The company has been a forerunner in the compact diesel engine market worldwide. The company developed its first engine--a vertical 5 HP diesel--in 1930. In 1933, it developed and put into production the world's first small, horizontal diesel engine--the Model HB5. Yanmar has now built over 15 million diesel engines ranging in size from 4.5 HP to 5,000 HP. Over one-million engines have been sold in the U.S. alone.

The Yanmar brand was adopted in 1921. The company produced its first tractor in 1937--a simple, walk-behind machine.

In 1952, the company changed its name to the Yanmar Diesel Engine Company, Limited. This was later simplified to the Yanmar Company, Limited.

Yanmar has had a relationship with John Deere since the 1970's. By 1986, it had shipped over 100,000 tractors to that company alone. Probably because of increasing pressure from John Deere, Yanmar stopped selling new tractors in the United States in the 1980's; however, a Yanmar caterpillar-type tractor is now available in California, primarily for use in vineyards there.

The Yanmar name in Japan is equivalent to the John Deere name in the United States. The company makes everything from push mowers to huge rice combines. In the United States, Yanmar engines power equipment for construction, agriculture, industry, and the military, including applications such as excavators, wheel loaders, backhoes, generators, refrigeration units, pressure washers, outboard motors, and engines for fishing boats, as will as tractors. Yanmar has working relationships with many American firms, including Mercruiser.

Yanmar Company, Limited, has sales and service firms in over 130 countries around the world. The Yanmar AmericanCorporation has its headquarters in Buffalo Grove, Illinois.
