1100 >>> arrestor Gone !!!!

TWO GUNS · Dec 22, 2007

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?

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......

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.

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 ....
