Yes. Tier 4 compliant but Indirect injection; mechanical fuel injection Tier 4 regs are complex, the criteria for the power and application of the engines that are required to meet these standards have broadened significantly. I see a lot of just under new 25hp diesel equipment. I know Kubota discontinued their F3990 mower(39hp) because so many emissions issues. My neighbor has a newer Deere 1025 tractor with no emissions. It's sub compact though.
