The spline transmits all of the tractor’s PTO torque through interlocking teeth on the yoke bore and the PTO stub. A 6-spline interface has six teeth distributing the load, while a 21-spline<\/strong> interface spreads the same torque across twenty-one teeth, resulting in lower stress per tooth. This is why higher-HP, 1000-RPM PTO outputs typically use 21-spline connections. Choosing the Tractor PTO Spline Shaft with the correct tooth count and diameter ensures a tight fit that doesn’t wear, rattle, or slip during operation.<\/p>\n

Not every tractor-to-implement combination uses the same spline on both ends. That’s where adapters come in. The Tractor PTO Spline Shaft for Agricultural Machinery is available in several spline configurations to handle mismatched equipment:<\/p>\n

Japanese-market tractors from Kubota, Yanmar, and Iseki often use metric spline dimensions (8-spline 38×32, 42×36, or 48×42 mm). We stock these alongside the standard inch configurations so Korean operators using Japanese compact tractors don’t need separate adapter bushings.<\/p>\n

Look at the tractor PTO stub end-on and count the raised teeth. Six large teeth = 6-spline. Twenty-one fine teeth = 21-spline. This is the fastest way to identify the configuration and it doesn’t require any tools.<\/p>\n

Y\u00f6ntem 2: \u00c7ap\u0131 \u00d6l\u00e7\u00fcn<\/h3>\n

Use a caliper across the outer diameter of the PTO stub. Common readings: 34.9 mm (1-3\/8″) for both 6 and 21 spline, 44.5 mm (1-3\/4″) for heavy-duty 6 or 20 spline, or metric sizes like 38 mm for Japanese compact tractors.<\/p>\n

The operator’s manual specifies the PTO spline type. If you’ve lost the manual, our Korean support team can look up the spline configuration by tractor make and model. Send us your tractor details and we’ll confirm the correct Tractor PTO Spline Shaft specification within one business day.<\/p>\n

Spline wear is the gradual loss of material on the interlocking teeth of the yoke bore and PTO stub. Once wear passes a critical point, the connection develops play that accelerates further damage and can lead to rounding off of the teeth entirely. Here’s what to watch for:<\/p>\n
