Of all things, you would expect a seat belt to work flawlessly.
I am beyond livid.
Today I laid my BX25 on it's side, a slow plop over and I could NOT
get the seat belt buckle to release. I am SO MAD. It simply would not
unbuckle. After several minutes I was able to get enough of my
bodys weight off the buckle, and finally it released after poking it
with a stick. SO EFFIN MAD!. I was SO CLOSE
to cutting my way out.

I weigh 240 pounds dressed.

Did I say I was MAD???

Wife will be calling corporate in the AM.

SO MAD!

Yikes... glad you are okay and the seat belt held! I was going to make a crack like, 'how much do you weigh undressed!'. Decided that wasn't appropriate.

Seriously, was it because you couldn't 'unload' the weight on the belt? Also, how did you you lay it over? I ask only as a potential teaching experience. I have had a few very close calls. Again, glad you are okay and you were wearing your seatbelt!

That is totally normal seatbelt operation. Corporate isn't going to help with that one. Maybe you can get the paddle style mechanism you find in planes and race cars if you want something that will release with pressure on it. Or, as you describe, carry a cutter.
Sorry to hear about the roll. Glad everyone is OK! Thank goodness you had the belt on!!

I've never found a tractor seat belt that didn't suck. I've lucky never tested that aspect of them.

From my aerospace experience and be it limited when it comes to seat belts... I agree! I have tested a couple involuntarily, but not in life threatening situations. I guess they worked. Design wise though seems they could be more advanced. Seat belts... IIRC originated at Indy and open wheel racing. Also side view mirrors. Someone should fact check me. But racing and other at the edge 'sports' are what propagate most of our safety initiatives. Empirical learning!

gee i dont know my friend. we hear stories all the time about people being trapped all the time in seatbelts in cars after car flips or crashed or what have you. how would you expect a tractor to be better with seatbelts?
i just cant wear seatbelts while working around yard or customer home. i am getting in a out so many times -- just not worth it. the only time i used the seatbelt is road travel - but i dont do that anymore -- too slow.

i understand you are mad you couldn't get out - it got to be scary with a flipped tractor pushing on you or about to and you trying to get away to safety but the seatbelt not letting you. (tractor possessed maybe :p)

__Everyone who uses these tractors and who are on slopes and who
push them w/ real work NEED to carry a knife capable of cutting
that belt.
I will be affixing one, onto the ROPS where I can get at it
if it happens again. NEVER did I foresee a seat belt inop situation.
NEVER!

How? Simple. Operator Error in every aspect. They don't fall over themselves.
Not a "roll" it just plopped onto its side, real slow. Took maybe 4 full seconds.

I was carrying slash, that was piled as big as 6 school buses, Compacted,
that I feed to the fire, down hill, all off camber. Over and over and over...
Those whom remember the GRAPPLEOMATIC know
I have modified my BX, a lot. (That grapple was the best I
could have built for it BTW
) So I was carrying a GIANT grip of slash, one
pine sapling about 3" in diameter was hanging straight down on center
of the bucket and a spider web of slash was hanging out 10' easy in several
directions, wet! . Boom high, right turn on edge of fire precipice, fire on hillside,
about 3' below bottom of tires, sloped down to fire level.
The boom gets fully clocked from left to right each trip to slash pile to
compensate for off camber gravity.


I FORGOT to move BH boom full LEFT for drop, the tree hanging on center
did not allow bucket to drop
, full right turn front wheels
then the dirt gave way under right front tire. The perfect storm...

I felt it coming, no big deal just lower FEL bucket FAST NOW, BUT,
that 3" tree on center OF BUCKET? Well, it would NOT let
the bucket drop, the boom was on wrong side for better stability, and then
it happened, dirt under right front wheel gave way...

Like I said, operator error. They don't move unless a human is at the controls.
You get in a machine,you use it, and gravity, you take risks.

No speak-able damage other than my pride, that heals quick.
I sincerely am more interested in others hearing my story.

I know a defective part when I experience one. So what that I caused the
lesser issue at hand, this seat belt buckle release mechanism failure is inexcusable.

I want a whole new seat and belt system now, has anyone seen a good thread on said?

PS, remember the full cage roll bar I made?
(Yes it and the radioOmatic moved the CG, risk known...)
It came in handy, otherwise I would have had a face full of slash.

It took me a full 6 minutes and about 32 seconds to right the
BX using my new to me, CAT DC3 Series 3 you guys don't know about.
I patted myself on the back for those fast moves.
The time stamps on the pics don't lie, and that includes
pic taking time. When time permits I'll try to post up the
2 pics I took.

:)

"It" happens... God is great.

The seat belt operated normally. Pressure on the mechanism is suppose to keep it locked.

x2!

Sorry to hear that you had a bugger of a time releasing the pressure at the locking mechanism, but it did exactly what it was designed to do = keep you safely in the seat during a 'roll-over' (even onto your side) situation.

Corporate (Kubota, or any other OEM for that matter) doesn't make their own seat belt latches. If you go in with an angry letter, they will simply reply with a "Thanks for your letter" letter.

I can't quit laughing at the 2 posts that say the buckle worked as advertised.

BS. If car is burning, and you are upside down, and not as strong as me
or mindfull as me to look for a tool to help,
you would be DEAD. Utter nonsense.

The buckle failed and no one can tell me otherwise.

PS, the buckle now fails full time, even at rest.

It is a pos, period.

Go put 240# of pressure on any vehicle seatbelt- it will have the same issue. Heck go buckle the seatbelt in your car and pull on it as hard as you can while trying to unbuckle- it will be difficult to impossible to remove. That is the nature of the design. I've been in the profession that deals with the scenario you describe above for many years. It's the reality of the design. We have seatbelt cutters everywhere- on our person, on our extrication tools etc. Google seatbelt cutter- you will find several. The little plastic ones that look like a letter opener work fine.

The seatbelt needs replacement because of bent internals. It's normal for that to occur as well.

Well, laugh away Mate. You're not keeping me up at night. :)

Here's my experience, though. I wrecked on black ice once and the ute flipped on its driver's side. I was unhurt but was (of course) lying on my side with my full weight hanging from the belt buckle. It would not disengage until I lifted myself up enough to relieve the pressure. After that, it came undone.

Just as it is designed to do.

I'm sure that you can come up with scenarios (such as a your non-ROPS equipped burning car example) where you'd be screwed. That's why emergency response personnel/vehicles carry seat-belt cutters... the majority of the time, if you're injured, staying in the seat is the safest thing to do.

There are different 'buckles' for different uses. What are you going to recommend? A 5-point harness?

Well Mate, seeing as you're going to need to replace... you could research a replacement passenger aircraft type 'lift' buckle. Perhaps that will suit you.

Sorry to hear about your roll over. Very scary thing to experance that's for sure. I've spent some time working with seat belts over my lifetime and I'll try and explain how they work of at least how I was trained on how they work.

First of all a seat belt has one goal in mind when you clip it on and that's to keep you in the seat.

Your tractors seat belt is a simple design compared to most used in today's vehicles. Your tractors seat belt has an internal ratchet system and an inertia switch in it that will lock the belt and you in place once that switch goes out of its normally level position. Once activated the only way to release it is to let it retract a small bit. If it don't find that slackness it won't release the ratchet and it can be very difficult to even release the latch to the the stress that on the system.

It's a sample but effective system because if you were upside down in your tractor and water was under you and you were unconscious at the time of the roll over you could possibly drown if that belt let go so your seat belt worked as designed and be thankful it did. If it hadn't you might have been crushed by the machine when you rolled it. It did its job. Your alive, be thankful for it.

Insidently. It's not well known but in the case of an accident where a seat belt was used by an occupant that seat belt should be replaced to insure you'll be protected in another event. I've seen situations where a belt actually had to be cut off to get occupants out of their seats. Weather you agree with me or not I just wanted you to read this. Be thankful yours did what it was supposed to do and we can sit here a read that your safe and sound.
Keep safe out there.

I thought that that might be the case but I didn't want to speculate.

The thought that it was the case (replace if it's been 'engaged') was like that of a motorcycle helmet... once 'used', even if it looks OK, the chinstrap is cut off, the helmet is discarded and you buy a new one. The internal "integrity" is gone.

Great quote. Seat belt worked as designed. It was heavily loaded and now should be replaced
