The Kawasaki engine is quieter across the full rpm range than the diesel. How much so I cant tell you. But it is quieter
Diesel compared to gas noise at idle
This is not a diesel vs gas conversation. I am interested in the dB level of the x7 series gas compared to diesel, primarily at low idle. Anyone with experience please chime in. It doesn’t have to be a specific dB reading, but that would be great too.

I can tell you that my neighbor has a Kubota RTV900 diesel that is so noisy at idle that I have to have him turn it off so we can have a conversation when he comes over. However, the neighbor between us has a gas Gator that you can barely hear it run in comparison.

Thanks guys. I do enjoy the quiet and smoothness of the Kawasaki. Not taking anything away from the Yanmar though, it is smooth and quiet compared to the old diesels.
I bet somewhere there is an EPA certification for both the Yanmar TNV engine and the Kawi FD750 for noise.
Mother Deere certainly knows but not sure she's going to divulge it even though it's probably public information.

There are soundmeter apps one can download and use on smartphones. Might help get some quantitative data if interested folks used the same apps and measured dB level from the same position (maybe the driver's seat) on diesel and gas tractors.
Yea I will get some fresh data tonight and post it. We need your 455 dB too.
I will do idle, half, full throttle readings.

DB readings are very skewed by how far away the meter is from the sound source. A small difference in distance makes a big difference in readings.
Note: The old school diesel in my 2305 is much quieter than the mini max in the X758 especially at WOT.
interesting about your older diesel vs the new one in x758. They call this one the minimax? Is that a Yanmar term? How big is your older diesel and what’s the PTO RPM on it?DB readings are very skewed by how far away the meter is from the sound source.

The JD 2305 is a 2006 model, the X758 is a 2018.
The 2305 is 1.1 Liter, the X758 is .993 Liter. PTO speed on the 2305 is 2500RPM vs 3600 RPM on the X758
The X758 is way louder at idle and particularly WOT.
You can talk to someone at 2500 RPM with the 2305 and not have to shout.
Problem is the mic on smartphones isn't meant for this kind of use and maxes out pretty low. My samsung maxes out just over 90db. Found that out trying to compare two generators, it said 90db for both from right next to it to 50+' away.There are soundmeter apps one can download and use on smartphones.

Yes that is a Yanmar term. They seem to be smaller displacement and run higher RPMsinteresting about your older diesel vs the new one in x758. They call this one the minimax? Is that a Yanmar term? How big is your older diesel and what’s the PTO RPM on it?
