Description

When you’re running PTO equipment, watching engine load, or just keeping an eye on your engine’s health, you need a reliable rev counter that gives you accurate readings. If your Massey Ferguson’s tachometer has quit or gotten erratic, you’re essentially flying blind on engine speed—not something you want when you’re trying to protect expensive equipment.

What You’re Getting

Mechanical drive system that works reliably without electrical connections or wiring hassles
Clear dial face with precise markings so you can read RPM at a glance
Heavy-duty construction built to handle constant tractor vibration and harsh field conditions
Early-type design specifically engineered for 300 series compatibility
Weather-sealed housing keeps dust, moisture, and debris out of the works

Built for Real Farm Work

The 300 series tractors handle everything from tillage and planting to hay making and loader work, and proper engine speed monitoring is crucial when operating PTO implements like balers, mowers, and spreaders that need specific RPM ranges to work correctly. Whether you’re running a 365 for utility work or pushing a 399 through heavy tillage, this rev counter helps you find that sweet spot for maximum power without over-revving.

Made to Last

Mechanical tachometers take a beating from constant vibration and temperature swings. This one uses robust internal components and precision gearing that stay accurate even after years of hard use. The dial face resists fading from UV exposure, while the housing materials withstand impacts and resist corrosion from farm chemicals.

Good to Know

This early-type design connects through a flexible cable from the transmission drive. When installing, check your cable for wear or damage—a bad cable can cause erratic readings even with a new gauge. Keep the cable properly routed to prevent kinking, and always verify compatibility with your specific model year and serial number since later 300 series tractors may have different arrangements.
