Hard cab poisoning?

Recommended Posts

fishnwiz

Just curious...I always wondered about carbon monoxide issues with some of the hard cabs that are tractor mounted almost on top of a running gas engine. Are these cabs not that air tight that this is never an issue or could this be a real life issue with some of these cabs?

I think it's mostly a not-so-airtight seal. The other thing that can help is in our engine configurations the intake is from the operator/dash end and flows out the grill/nose. That helps to pump some of the fumes out of the cab space.

I am not buying one myself but was told by a guy I know who owned one that he used to get headaches when he used his hard cab for more then 1/2hr or so when blow in snow..

I was just curious if these were ever an issue.

Thanks for the input.

The base/seal of it sits over the very back of the hood, over the back of the battery compartment. The back side of the engine probably sits a foot or so out in front of it. And, keep in mind, that the exhaust is blown out the front of the motor, and off to the side. I don't think you'd get any more exhaust fumes in the cab than you'd get blown back in your face from wind while out mowing without a cab; probably even less. Now, that being said, that's just my thoughts from using the cab for the first time last winter. It never occurred to me to put a tester in the cab to see. Maybe I'll do that this winter if I remember, just to see.

Unless that thing is sealed up tight and the exhaust is somehow being pushed/sucked into the cab, I'd have a tough time imagining any issues with that. As far as headaches, I can't say that it wasn't from CO but it could also just have been from exhaust/noise/etc in general in the cab. I get headaches from being around kerosene torpedo heaters even if it is sitting outside. Most likely not CO and just me being sensitive to the exhaust.

Years later he found a cab (don't think it was a Case cab, but not bad looking) and only used it a couple of times and took it off. He never said but I suspect that it might have been the exhaust as his K341 ran pretty smokey.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
