4th Speed Transmission Gear for Massey Ferguson 100-600 Series and 35-65 Series Tractors

Description

When your Massey’s transmission starts grinding or slipping out of 4th gear, you know it’s time to get inside and fix what’s worn. This 33-tooth gear sits on the bottom shaft of your 8-speed transmission and handles a lot of the power transfer in that crucial middle range where you spend most of your field time. It’s the gear that gets you moving at a good clip for cultivating, planting, and lighter tillage work.

What You’re Getting

• Precision-cut 33 teeth that mesh properly with mating gears for smooth operation
• 17-spline internal pattern matches your transmission shaft exactly
• Heat-treated steel construction resists wear and tooth breakage under load
• Direct replacement for worn original gears – no modifications needed
• Factory specifications ensure proper gear ratios and smooth shifting

Built for Real Farm Work

This gear fits a wide range of Massey Ferguson tractors from the smaller 35 and 65 series up through the popular 100, 200, 300, 500, and 600 series models. These are the workhorses you’ll find on farms everywhere – from compact utility tractors handling chores around the barnyard to mid-size row-crop machines putting in long days during planting and harvest season.

Made to Last

Transmission gears take tremendous stress, constantly meshing and unmeshing while transferring engine power to the wheels. This replacement gear uses quality steel with proper heat treatment to handle those loads without premature wear. The tooth profile is machined to exact specifications, ensuring it’ll mesh smoothly with other transmission components and provide years of reliable service.

Good to Know

Replacing transmission gears requires splitting the tractor, so this is typically a job for someone comfortable with major mechanical work or a professional shop. While you’ve got the transmission apart, it’s smart to inspect all the other gears, synchros, and bearings – and replace the transmission oil and filter when you button everything back up. Always use the proper gear oil specified for your model.
