ACEBRI PTO Clutch Replacement for John Deere: AM131779 GX335-GX345,325-335-345,GX355 Clutch for Ogura: MA-GT-JD23BF MAGTJD23BF Mower Clutch

What It Is

The ACEBRI PTO clutch is an aftermarket replacement for the electric clutch that engages and disengages your mower deck blades. It’s designed for select John Deere lawn and garden tractors (GX335, GX345, 325, 335, 345, GX355) and is a direct cross for Ogura part MA-GT-JD23BF / MAGTJD23BF.

Fitment & Compatibility

Before buying, verify two things: your model number and your OEM part number. This clutch replaces John Deere AM131779 and fits GX335, GX345, 325, 335, 345, and GX355 tractors. It does not fit all Deere models—check your equipment’s serial number against the AM131779 listing. Measure your existing clutch’s shaft diameter (typically 1”) and bolt pattern (three-bolt, 3.125” center-to-center). Also confirm your pulley groove width matches your belt (usually 1/2” or 5/8”). If your mower uses a different OEM clutch number (e.g., AM132244), this won’t work.

Key Things to Know

• Quality variance: With a 3.7 rating from only 9 reviews, expect potential fitment or durability issues. Aftermarket clutches often have shorter lifespans than OEM John Deere or Ogura units.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and may need to remove the mower deck. No special wiring—plug-and-play if your connector matches.
• Common gotcha: The clutch may arrive with a different connector style than your tractor’s harness. Check photos or buy a pigtail adapter separately. Also, verify the pulley is not warped—defects are rare but possible.
• Price vs. value: At $129, it’s roughly half the cost of an OEM Deere clutch. If you’re on a tight budget and need a quick fix, it’s an option—but don’t expect OEM longevity.

Should You Buy It

Buy this clutch if you have a confirmed AM131779-compatible John Deere tractor, need a low-cost replacement, and are comfortable with moderate DIY installation. Skip it if you want OEM reliability, have a high-use commercial mower, or can’t afford downtime from a potential early failure. For occasional residential use on a 325/345 series, it’s a reasonable budget pick.
