Description

When your tractor’s running rough or losing power, worn exhaust valves could be the culprit. These valves take a beating from hot combustion gases day after day, and when they start wearing out, you’ll notice it in your engine’s performance. This TISCO exhaust valve gets your John Deere gas engine breathing properly again, restoring that smooth power you count on.

What You’re Getting

Direct replacement for original equipment—same dimensions and tolerances as what came from the factory
Heat-treated construction that handles the extreme temperatures exhaust valves face every day
Precision-machined seating surfaces for proper compression and gas flow
Multiple valves per engine mean you can tackle a complete valve job while you’re at it

Built for Real Farm Work

This exhaust valve fits John Deere tractors with 135 CID 3-cylinder, 180 CID 4-cylinder, and 202 CID 4-cylinder gas engines. These are the workhorses you’ll find in utility tractors handling everything from mowing and loader work to light field operations. Whether you’re maintaining pastures, moving hay, or doing chores around the farm, these engines need proper valve sealing to deliver reliable power.

Made to Last

Exhaust valves live in one of the harshest environments in your engine, dealing with combustion temperatures and corrosive exhaust gases. This TISCO valve is manufactured to OEM standards with materials selected to withstand that punishment while maintaining proper sealing for thousands of hours of operation.

Good to Know

Your 3-cylinder engine uses 3 exhaust valves, while the 4-cylinder engines use 4—so plan accordingly if you’re doing a complete valve job. While you’ve got the head apart, it’s a good time to check valve guides, springs, and seats. A valve job isn’t something you tackle every season, but when it’s time, quality replacement parts make all the difference in how long the repair lasts.
