Description
That side-discharge exhaust blowing smoke in your face every time the wind shifts isn’t just annoying—it’s unhealthy and makes long workdays miserable. This over-bonnet exhaust system routes those fumes up and over the hood, giving you clean air to breathe while cutting down the noise that makes conversation impossible during operation.
What You’re Getting
- Over-hood design eliminates operator exposure to exhaust fumes and improves air quality in the cab
- Vertical stack configuration creates better draft and reduces back pressure for improved engine performance
- Durable construction built to withstand years of heat cycles and farm conditions
- Significantly reduces noise levels compared to side-exit exhausts
- Direct fit design engineered specifically for your tractor model
Built for Real Farm Work
Your John Deere 20 and 30 series tractor is the reliable workhorse for countless farming tasks—from cultivating row crops to running hay equipment or operating a loader around the farmyard. These models are particularly popular for their versatility, but the original side-exit exhausts can make operating them unpleasant, especially during loader work where you’re constantly stopping and accelerating.
Made to Last
The vertical stack design doesn’t just move exhaust away—it actually improves engine performance by creating better draft. Hot exhaust gases naturally rise, helping pull fresh exhaust from the engine more efficiently than horizontal designs. This can lead to slightly better fuel economy and smoother running.
Installation Notes
Over-bonnet routing requires careful measurement to ensure hood clearance. Support the vertical section properly to prevent stress on manifold connections, and use quality clamps rated for exhaust temperatures. Most installations complete in 1-2 hours depending on your specific model. Pro tip: add a rain cap to prevent water entry during storage—vertical exhausts can collect rain, leading to rust issues.
