Forward Exit Horizontal Exhaust??

[dieselscout80]

Question as I only have a tractor with a vertical exhaust stack.

Do forward exiting horizontal exhaust system found on many cause the operator to breath in lots of exhaust fumes?

I have a forward pointing vertical exhaust on my open station Kubota M6040. Never bothers me. Sorry - just noticed you are asking about horizontal exhausts. I would guess they are not a problem either. But take a look at the picture of mine. Vertical with a tip that directs the exhaust gasses horizontally. Whatever - in use the exhaust gasses are never noticeable.

Thanks

I am tractor shopping and the reason I asked is the owners manual for my new to me Alamo SHD96 Flail mower says one cannot have an under tractor exhaust that exits to the rear.

Some of the tractors I've looked at have underslung exhaust systems, but I think they could be reversed and run forward. However, I have not run a tractor with a horizontal forward exiting exhaust.

I have a MF 135 diesel with the exhaust exiting downward under the left rear axle. We’ve been using it for almost 50 years with a rotary cutter and a flail a bit. Unsure of what the issue might be using a flail. Other than getting ‘gassed’ when hooking up an implement. I do prefer the front horizontal exit on my Kubota for that reason.

last tractor 82 Kubota L295DT had an under tractor horizontal rear exhaust, which would fume me out.
New LS MT240HE has horizontal forward exhaust, and I never notice it. Maybe it's because it is 39 years newer, maybe because it is Tier IV, either way it is a non-issue.

I'm confused dieselscout80. What is the supposed interaction between a rear facing horizontal exhaust and a flail mower??

A thought hit me. I wonder - is your flail mower OM saying this because they expect you to connect the mower while the tractor is still running? Are they concerned that a rearward pointing exhaust will gas you? With my extendable 3-point arms - I never need to connect anything with the tractor still running. Besides - tractor OFF is the only truly safe way to make connection.

OOSIK, in the Alamo Owners Manual in the "Hazards section" and its sub section of "FIRE PREVENTION GUIDELINES" in of the owner manual it says "DO NOT OPERATE mower on a tractor equipped with under frame exhaust" and that is all i know.

I wonder if the exhaust exits on the left rear side if the heat could effect the belt life of the fail mower?

I never hook up while my tractor is running.

I wonder if it could be - they are worried that hot sparks from the tractor exhaust could cause mower dust or dry mowed grass to ignite. Since it is in the Fire Prevention Guidelines section. Maybe the hot exhaust pipe igniting mowed grass as you drive over it.

It can very well happen. Mostly with the newer tractors with emissions, when it starts the regen process.

We have had big fires starting because the tractors started the regen process during brush mowing in forests with dry brush.
