ZEN-NOH and Kubota Part 4: Loopholes

An amaturish looking ZEN-NOH label on this Kubota tractor. Work of replacing Kubota hood decals at the export dock in Japan to satisfy US import requirements? We can only speculate of course.

An amaturish looking ZEN-NOH label on this Kubota tractor. Work of replacing Kubota hood decals at the export dock in Japan to satisfy US import requirements? We can only speculate of course.

This is the fourth of five installments that examine the history of ZEN-NOH equipment in North America and how these tractors came to be found in such great numbers. If you are just jumping into this series now, please review Part 1, Part 2 and Part 3 to give yourself some background information.

We last left off with Gamut Trading heading back to Apple Valley California in an effort to comply with the cease and desist order as a result of losing a trademark infringement case brought by Kubota. Part of the cease and desist order’s conditions were that existing Kubota equipment on the lots of the distribution network had to be 1) exported out of the country 2) parted out or 3) sold for scrap metal.

It was about this time, pondering these three alternatives for the equipment they had paid for, that Gamut realized that the trademark case only covered the Kubota name, not ZEN-NOH that they had seen all over the hoods and grille of ZEN-NOH branded Kubotas they had imported. This made them realize that they might be able to import and distribute ZEN-NOH equipment instead! A loophole around the court orders!

Back in Business
What a break! Ronald DePue and his brother Darrel were Chairman of the Board and CFO of Gamut Trading at the time. They performed a check at the United States Trademark Office and found that the trademark ZEN-NOH was available. The name was previously registered and owned in the United States by ZEN-NOH of Japan themselves. In 1988 in a weird twist of fate, ZEN-NOH failed to renew the trademark name leaving it available for adoption by Gamut Trading!

The original trademark registration filed by ZEN-NOH in the early 1980s. They let it expire in 1988 which left it open for Gamut Trading to pick up nearly 10 years later.

In March 1997 less than three weeks after Kubota’s legal dropped the hammer on them, Gamut Trading bought the ZEN-NOH trademark and name. They became the new owners of the brand for $245. They indicated on their trademark application that they were users of the ZEN-NOH trademark since 1986, long before they had probably even seen a ZEN-NOH tractor. We have a copy of Gamut’s full trademark application which you can see here.

In a legal move that now sounds strangely familiar – Gamut Trading also registered the name ZEN-NOH with United States Customs and Border Security to prevent any other entity from importing a used tractor from Japan bearing their trademark, ZEN-NOH. Kubota’s lawyers had schooled them in court and they were obviously paying attention to the lessons!

Even as Gamut was proceeding with an appeal against the USITC general exclusion order they had become the registered legal owners of the ZEN-NOH trademark. This would allow them to import all the ZEN-NOH branded tractors they could get their hands on, regardless of whether they were made by Yanmar or Kubota. Plus, as the new owner of the trademark, they could for a fee, sell a licensing agreement to future tractor importers or resellers wanting in on this still emerging market. Brilliant!

Kubota Strikes Back – Again
It is not known whether Gamut Trading actually instructed their export suppliers to remove the offending Kubota hood decals, but, as the new owners of the ZEN-NOH trademark and name brand, Gamut resumed importing used Kubota Tractors almost immediately after being served with the original cease and desist.

Between February 1997 and October 1998 Gamut continued to import used Kubota tractors. On 56 different shipments the tractors were identified as ZEN-NOH L and B Series Tractors on the customs declarations paperwork. The Border Services could not turn them away because there was no violation here – ZEN-NOH tractors were free to enter the United States.

When these ZEN-NOH tractors finally cleared customs, Gamut knew that their resellers would not want a no-name unheard of tractor brand. Gamut routinely advertised their tractors as Kubota/Zennoh tractors, stressing that the tractors are the same thing. They went as far as to supply new Kubota hood decals including instructions on how and where to install them!

Little did brothers Ron and Darrel of Gamut know, but, Kubota coporate was already onto their operation. Kubota hired private investigators posing as prospective tractor resellers, recording phone conversations and obtaining wire taps. The end was near.

Sued Into the Stone Age
When the dust settled on round two of the legal battle, Gamut was fined in excess of $2.3 million USD and found in violation of the original cease and desist order placed upon them by the USITC in February 1997. Kubota was seeking a penalty in the $6.9 million range, but since the directors of Gamut had willingly destroyed so many boxes of files and records pertaining to the importation of these tractors, the deciding Judge could only base the penalty amount on the information the investigators could find. We have a copy of the formal proceedings of Kubota Corp V. Gamut Trading et al available here.

Up Next, Fallout
After the lawsuits flew where did the chips fall? What did these players do afterward and what are they doing today? What impact did importing these tractors have? We answer these questions and provide a handy timeline of the whole puzzle in our upcoming and final segment of this series.

Kubota Battery Basics

Ahhh yes, the battery. Really handy when it comes to starting your Kubota but after that just seems like its along for the ride. Still, it is important that we think about the battery every now and then to avoid a situation where we are 5 miles away, sun going down, wolves starting to come out… you know the drill. Let us look at some ways to make sure your battery is the best it can be.

Cold Cranking Amperes
The CCA rating, or cold cranking amperes, of your Kubota’s battery is a measure of its ability to deliver current at a temperature of 0 degrees Fahrenheit (-18 Celsius) for 30 seconds – hence the reference to cold. We know that as the temperature decreases the efficiency of the battery decreases. This explains why the battery CCA rating is lower than its cranking amperes, or CA, rating measured at a warmer 32 degrees. Most cars have batteries around 500-600 CCA.

The engine in your Kubota is of high compression which means it takes a lot of muscle to get it going in the first place. We recommend at least a 850 CCA rated battery or even 1000 CCA if you live in a cooler climate. It is important to remember that even if the battery is fully charged and fresh, if it lacks the ability to deliver enough current to get that engine turning over your equipment will not start – especially on cold days.

A battery that we pulled during routine service. Although the battery was fully charged, the CCA rating here is 525 which is too low. Replacing the battery with one that offered higher CCAs will greatly decrease starting effort.

Hold Down Bracket
Most of Kubota’s lineup ship from the factory with some sort of battery hold or tie mechanism. Usually it is just an angled bracket that holds the battery snug with a couple of long bolts. The purpose of this bracket is to reduce the amount of shock and vibration transferred to the battery during normal operation – and operating a tractor can be a bit rough sometimes.

The reason we want to reduce vibration to the battery is to prevent the parallel lead plates inside of the battery from colliding and destroying themselves. There are 6 cells in a standard battery. Each time a cell is destroyed expect a drop of 2.1V across the terminals – not good. Vibration is a quick way to destroy your new battery.

Does this mean you need to purchase an expensive anti vibration battery too? No. I do not think that the value is there for anti vibration batteries. Make use of your battery hold down bracket or get one if you have lost it and you are set.

Know Your Battery Terminals
Inspect your battery terminals. They should be free of chalky white corrosion and nice and snug on the battery posts. Make sure you have a solid ground connection to the frame. So far, easy right?

Comparison between old connectors that need replacement. The old connector had a crack all the way through its right side. This meant regardless of how tight the connector was closed around the post, a good connection would never be made.

Something that is often overlooked is caused by the type of terminal connector itself. There are typically two types of battery terminal connectors:

  1. enclosed style – these have the terminal connector and wire lead as one piece
  2. clamp style – these sandwich the wire from the lead at the back of the connector

What can happen over time with enclosed connectors is the wire inside the sheath can wear and break at the base of the connector. Since everything is enclosed you cannot actually see that the wire is making poor contact with the end of the connector! You will pull your hair out testing everything else (battery, alternator, belts, regulator, etc) before you realize the base of the connector is at fault.

We prefer to use the open, clamp style connectors. It is plain and easy to see if the wire lead is making proper contact. Case closed.

Left - clamp-style connector. Right - enclosed-style connector where the wire can break at or inside the base of the connector leading to unexplainable electrical malfunction.

Test the Voltage
As mentioned earlier, your Kubota’s battery has 6 cells in it producing 2.1V. When organized in series inside the battery the combined voltage is 12.6V. Take a volt meter across the terminals of your battery periodically and confirm that you are in the neighborhood.

Anything too far off 12.6V and start looking at the rest of your charging system to make sure everything is up to snuff. Unlike our road vehicles, when the battery is not being charged properly it can take months or even a year before that problem manifests itself as a failure to start. It simply takes that long to run the battery down when you do not have a radio, air conditioner or DVD player to power (with exception to the newer M and Grand L series of course!).

Using a volt meter to measure across the terminals. 12.5V reading here means this battery is well charged (but still not enough CCAs to be useful in our Kubota).

Battery Recommendation
Again, you do not need an expensive antishock battery here. We use Energizer batteries rated at 850+ CCA from WalMart. Others have had good luck with Exide or Allstate Mega-tron (sounds like a gun or something). All priced around $80-100 + battery disposal tax.

Summary
In short, some things you can do to make sure your battery is in good working order for when you need it:

  • use a battery rated at 850 CCA or higher
  • make use of the battery hold down bracket to prevent premature failure
  • make sure your battery terminals are clean and tight on the posts
  • use open, clamp-style terminals if you can opposed to enclosed terminals
  • periodically measure the voltage across the terminals – a properly charged battery should be around 12.6V

Putting the Mower to Work

Mowing tall grass with Kubota

OrangeTractorTalks reader Jamie from Zambia, Africa (map) has posted a picture of his L1501 tackling the task of mowing elephant grass in our gallery. This grass can grow upwards of 8-9 feet in height! Regardless of how much you might neglect your own lawn or brush, I bet your mower has less than this to contend with! Keep those blades sharp and that mower serviced.

Great pic Jamie, thank you for sharing. If you have a picture of your favorite orange machine in action or just sitting pretty, upload a picture of it.
