1100 >>> arrestor Gone !!!!

[TWO GUNS]

Thanks to Mikeyd,
Friend found the spark arrestor, it was a internal style !!! he has only a few hours on his unit. I'm attaching a pic of this thing >>>> it's so clogged up, I don't see how this machine even run >>>> And on top of that, he's running tracks in the mountains >>>>
Done some research today, and found out that the new 900's will have the internal arrestor system like the 1100 series, not just the screen caps.

So seeing what I've seen on mine, and seeing this on his, I would advise folks to remove these things, so their engines a work at their best performance.....

Is removing it from the 1100 or the new 900 easy?

What effect does that have on the warranty if any?

 

[Robert_in_NY]

I would contact Kubota about that and ask them about it. Tell them the problem, show them the picture and see if they realize this is a problem.

Speaking of Kubota, I just found out the Kubota dealer a few towns over doesn't sell Kubota's anymore. Now I will have to go further to the other Kubota dealers in hopes of getting an RTV to demo I had a better chance of getting a demo from the dealer that quit selling Kubota's (I won't even speculate why they don't sell them anymore but I think I know why )

Removing it is really easy....

And from talking to a Kubota production engineer, and sending him the photo, he & Kubota knows of the situations, but the goverment make 'em install them for reasons on running on goverment property. By law, any equipment running on gov. property, will have a spark arrestor on it ....
Does not effect the warranty at all >>>>
And it's all up to the owner / customer to remove them. I know on my 900, just within a few hours, mine was clogging up. And I removed it, and instantly, you could tell the differance in performance, but of course, it could breath better. And didn't get any louder at all >>>>>
Now if a man wanted to keep it on, he has that option, but he would have to keep a watch on it , and clean it often ~~~~

Robert in NY,
Might have much to do with the code of ethics, and the level of things, that Kubota is making all dealers come up to in the coming up year. And the dealer don't want to step up to that level , or change his ways >>>>> Kubota is beefing up more and more of their ways of doing things, from every level of production, sales, promotions, and warranties >>>>>> Some of the "upgrades " Kubota is going to ...... some Dealers, will have to really get off their butts, and make that change, or they will loose their dealership with Kubota !!!!!

That's not speculation, that's a FACT !!!

It is true spark arrestors are required to run a machine on any federal and most, if not all, other government lands.
There is an elaborate testing process spark arrestors must go through to meet the USDA/federal requirements. You can't blame Kubota for this as they really have no say in the requirements. I can see where a spark arrestor for a diesel with it's exhaust particulate matter could be a real challenge.

Frequent cleaning appears to be necessary from the pictures, no way around it. If not running on government land/trail systems it could be removed and replaced with a fabricated turn down if that is needed. Curious- is the arrestor marked as USDA/Forest Service approved? I ask because my Yamaha Rhino SA is not marked even though it supposedly meets the requirements. Not being marked can be a problem with an inspecting LEO out on the trail......

 

[mikeyd]

Wow, I can't believe how clogged that thing is. Its a wonder it would even run, had to be killing the performance. A government regulation requiring a spark arrestor on a diesel makes about as much sense as the government regulation mandating those darn "spillproof" (more like spill all over the place) gas cans.

 

[TWO GUNS]

I know is my case, think it was somewhere in the 10-13 hour of it being new, I notice my performance making a dive, someone stated, " check the arrestor " I did, and it looked just like that one in the picture, but smaller.
Mine was the cap on the end of the tailpipe, I removed it, and like to have passed out. Ripped out the screen and re-installed the cap. And my performance JUMPED right back up. Heck, all them arrestor systems do is slow down the diesels....
I know it's not Kubota's fault, it the goverment making them install them ....

On federal land they(arrestor) helps to prevent from igniteing the grass/leaves and a forest fire.

This is a real concern on any land.
Safest bet is to clean the arrestor.

Spark Arresters - What is the Law?


California Vehicle Code Section 38366 Spark Arrester Law - Laws and Safety

"CVC 38366. (a) Notwithstanding Section 4442 of the Public Resources Code, and except for vehicles with mufflers as provided in Article 2 (commencing with Section 27150) of Chapter 5 of Division 12, no person shall use, operate, or allow to be used or operated, any off-highway motor vehicle, as defined in Section 38006, on any forest-covered land, brush-covered land, or grass-covered land unless the vehicle is equipped with a spark arrester maintained in effective working order.

(b) A spark arrester affixed to the exhaust system of a vehicle subject to this section shall not be placed or mounted in such a manner as to allow flames or heat from the exhaust system to ignite any flammable material.

(c) A spark arrester is a device constructed of nonflammable materials specifically for the purpose of removing and retaining carbon and other flammable particles over 0.0232 of an inch in size from the exhaust flow of an internal combustion engine or which is qualified and rated by the United States Forest Service.

(d) Subdivision (a) shall not be applicable to vehicles being operated off the highway in an organized racing or competitive event upon a closed course, which is conducted under the auspices of a recognized sanctioning body and by permit issued by the fire protection authority having jurisdiction."

US Forest Service Forest San Bernardino National Forest Order No. 5 - Roads and Trails

Pursuant to 36 CFR 261.50 (a) and (b) each of the following acts are prohibited on the identified areas under my jurisdiction:

4. Operating a vehicle in violation of the California Vehicle Code. 261.54d

Violation of these prohibition is punishable by a fine of not more than $5,000 or 6 months imprisonment or both. See 16 USC 551.

Similar laws are in place throughout the U.S.
For the 2% or less increase in performance this is a huge liability.

It's not that difficult to clean and maintain the arrester.

If we want to continue to ride on Federal land we should be responsible and do our part to keep it safe.
Fires are a real hazard everywhere.

I don't.

We do not have to worry about wildfires like you guys out west and I am glad we don't. However, I went on a atv ride one time with a friend and we started at his friends house. They were leading us and we went thru some nice area. Next thing I know we are entering state land which is off limits to ATV's. I asked about it and they just laughed about it and kept going. I went back and loaded up my atv and went home. I then told my DEC officer friend about it and left it up to them to take care of the problem.

People who do things that violate the rules on state and federal land only hurt everyone. In our area, people like the guys I followed enjoy tearing up the state land and that looks bad for all the guys running ATV's. In the areas where wild fires are an issue what type of reputation will UTV owners have if a fire is caused by removing the spark arrestor. It will make no difference in the publics eye as to why, all they will know is a UTV caused this.

I would not throw the arrestors away but if you know there is a fire hazzard then put it back on and maintain it until the fire hazzard passes.

Quote from National Wildfire Coordinating Group (NWCG):

"Turbochargers qualify as effective spark arresters when 100
percent of the exhaust gases pass through the turbine wheel.
The turbine wheel must be turning at all times and there
must be no exhaust bypass to the atmosphere. Depending on
design, small enclosed system bypasses that reroute some
of the exhaust back through the engine may be allowed."

Some people don't understand that there are groups of people that are actively trying to limit or stop where we can ride utv's.
Law abiding owners suffer from the actions of irresponsible owners.

Even if the fire is started on private land. The arsonist is responsible for the cost of extinguishing the fire. What if someone dies?

My sons and I ride almost daily. Safety comes 1st. We carry fire extinguishers with us at all times.

Pa has very,very few places state or federal you are permitted to ride atv's. The closest to me is over 80 miles and is only 10 miles of trails. Pa DCNR makes you register and liscense atv's and yet does not provide any where to ride. It is nothing more than another tax and a way of the state getting more money to waste. It also insures that if I sell my atv to another person the state has a way of tracking to collect sales tax again on the item. The way that is done is they send the renewal. If I don't renew they then send me notice that I need to do so or provide them with the information for the person who bought it. Taxes! It is a bunch of nonsense.

There are alot of trails for snowmobiles but atv's can forget it. I have had atv's for 25-30 years. We ride strictly on private land. I am sick of all of the beuocracy(hope that is spelled right). Regualtion and Taxes are destroying this country.

If I find somewhere to ride on Federal land I guess I will have to follow the rules.

Sorry if I am offending anyone but that is just the way I feel.

I put removing a spark arrestor on a diesel in the same category as removing the stamps off a mattress. Take your diesel out at night, rev it to the moon and try to see a spark, you won't. On a gasoline engine I can see the sense in a spark arrestor, especially during dry weather, on a diesel its just silly.

I have to agree with Darkday, I could care less about riding on Federal land with all the rules and regulations and the rent a cops with nothing better to do than hassle law abiding citizens. No thanks.

Mike, Don't tell me you really take the tags off the mattress

If you think PA doesn't have many trails then you would really like NY as to my knowledge we have one trail. Most New Yorkers in this area go to PA to ride ATV's. Our registration money was suppose to go to building and maintaining a trail system but our former govenor decided to take all the money set aside from atv registration over the years and spend it on something else In NY it is illegal to even use your ATV on your own land unless it is licensed and registered unless you are a farmer. I have had a friend stopped in our driveway by a State Trooper a few years back as he pulled onto the edge of the shoulder when he came out of the yard into our driveway. The Trooper tried to write him a ticket for using an unlicensed vehicle till I explained to him it was a farm vehicle being used on my farm. He eventually saw the light and left without writing a ticket.

SHHHHH!!! Don't tell anyone, don't want to spend 5 years in Federal prison.

Your absolutely right about NY requiring registration(money) for atv's and then putting the extortion into the general fund where it is no doubt spent wisely.

Where I live the rent a cops hide in the woods and bust kids on dirtbikes and atv's who haven't yet been extorted. Another great use of taxpayer money. Hey, I feel safer.
