Anytime stepping off the operaters side and doing work at the loader is missarable. The exhaust pipe is bent to puff out in that exact spot. It should exit the opposite side where no human would be working. Is there some different bend pipe options from Kubota to solve this ? The only option now is to suffer and breath fumes or shut off the engine. Both not desirable. There is no DPF filter . Just a straight pipe after muffler.
