New L2501 seems really loud! Suggestions?

[ProjectKing]

Well I just got a new L2501 with front loader and backhoe. The engine seems really loud! The exhaust has a metallic rattle sound to it. My L3830 is much quieter sounding.

Using a dosimeter app on my phone I measured around 92 db at 1700 RPM. My L3830 is running around 90 db. The L2501 has a harsh exhaust note like a hammer hitting an anvil.

I'm curious if anyone else thinks their L2501, L3301, or L3901 is loud. I'm planning to drive another L2501 at dealer when I head down
there.

One thing to note. The tractor has off-road diesel in it. Not sure if that would make it run louder or not.

I've attached a pic of my two Kubota since we all like pics!

I have a 3301. The only thing thats loud is the HST on mine and that is "normal whine"

Yes my HST doesn't seem that bad. It whines some but nothing outrageous. Do you feel like you need earplugs when operating your tractor?

Yah I try to all the time. My ears already ring 24/7 so anything I can do to keep additional damage I try to.

That said I have run it sans earpro. Its not horrible at low rpm stuff but after awhile at higher rpm (2000rpm+) its loud enough to notice I should have been wearing earpro

Found this video on YouTube. This one sounds a lot like mine! Hear how harsh the exhaust is?

Okay sounds good. I'll be making a video series for mine soon

Dyed off-road diesel is just normal diesel with a little red dye in it to indicate no road usage taxes have been paid on it (don't ever get caught with it in a road vehicle) The red dye doesn't affect performance or combustion in any noticable way at all.

I thought off road diesel had higher sulfur content.

No. its the exact same diesel as on-road but has a crapton(technical term) of red dye in it. If you bought it recently its ULSD+dye to indicate its non-road taxed diesel. Thats it.
