SCITOO Yellow 27.5"-40.55" PTO Shaft, 1-3/8" PTO Drive Shaft 6 Splines Both Ends PTO Driveline Shaft, Series 1 PTO Shaft without Slip Clutch Fit For Bush Hog, Finish Mower, Tractor

What It Is

This is a telescoping PTO (Power Take-Off) drive shaft designed to connect a tractor’s rear PTO to implements like brush hogs, finish mowers, or other 3-point hitch gear. It transmits rotational power from the tractor to the implement, with adjustable length to fit different hitch distances.

Fitment & Compatibility

• Length range: 27.5 to 40.55 inches (collapsed to extended). Measure from tractor PTO stub to implement input shaft with implement raised and fully attached. Add 1–2 inches for clearance.
• Spline size: 1-3/8” diameter, 6 spline female couplers on both ends. Common for Category 1, 1-3/8” PTO stubs (most compact and subcompact tractors). Confirm your tractor and implement have matching male spline ends.
• Series 1: Light-to-medium duty. Not for high-horsepower (>40 HP) or heavy-tillage implements. Check your implement’s PTO requirement.
• No slip clutch: This shaft lacks overload protection. If your mower or bush hog doesn’t have its own slip clutch or shear bolt, risk of driveline damage on sudden stops or debris jams.
• Brand fit: Aftermarket replacement for many Bush Hog, Land Pride, Woods, or generic mowers with 1-3/8” 6-spline connections. Not OEM-specific; verify yoke fit on your implement’s input shaft.

Key Things to Know

• No slip clutch included – If your implement relies on the PTO shaft for overload protection, buy a version with a slip clutch or add one separately.
• Installation difficulty: Easy – slide onto tractor and implement splines, secure with pins/cotter pins (usually included). No special tools needed.
• Telescoping lock pin: Check that the locking pin engages firmly to prevent shaft separation. Some users report pin fit varies; test before heavy use.
• Quality: Yellow paint finish may chip over time. Grease fittings on yokes – apply grease before first use and regularly.

Should You Buy It

Buy this if you need an affordable, adjustable PTO shaft for a light-to-medium-duty mower or bush hog with 1-3/8” 6-spline connections and your implement already has its own slip clutch or shear bolt protection. Skip it if you require a slip clutch, need a heavier Series 3 or 4 shaft for higher HP, or want a premium OEM match.
