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

What It Is

This is a Series 1 PTO driveline shaft with 1-3/8" diameter, 6-spline ends on both sides, designed to connect a tractor’s PTO to a Bush Hog, finish mower, or other Category 1 implements. It has no slip clutch, so it’s for lighter-duty mowing where shock loads are minimal.

Fitment & Compatibility

Before buying, measure your implement’s input shaft and tractor’s PTO stub – both must be 1-3/8", 6-spline. Check the collapsed length (27.5") and extended length (40.55") against your tractor-to-implement distance. This fits most Bush Hog, Land Pride, and similar finish mowers with Series 1 yokes, but will not fit compact tractors with 1-1/8" or 7/8" PTO shafts. If your implement uses a slip clutch, this shaft is not a direct replacement without adding one.

Key Things to Know

• No slip clutch – Use only for light mowing (e.g., finish mowers, light brush) where sudden load changes are rare.
• Cut-to-fit – You may need to shorten the shaft or guard tube for your specific tractor-implement spacing; measure twice.
• Grease fittings – Apply grease to the telescoping sections and yoke bearings before first use.
• Installation – Straightforward bolt-on to standard Category 1 yokes; no special tools needed.

Should You Buy It

Buy this if you need a direct replacement PTO shaft for a Bush Hog or finish mower with 1-3/8" splines, you’re on a budget, and you don’t need slip-clutch protection. Skip it if your implement requires a slip clutch or you have a compact tractor with a smaller PTO stub.
