A 6-spline interface has six teeth distributing the load, while a <strong>21 \u0634\u0631\u064a\u062d\u0629<\/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&#8217;t wear, rattle, or slip during operation.<\/p>\n<h3 style=\"font-size: 19px; color: #2a5c8a; margin: 22px 0 10px 0;\">\u0645\u0642\u0627\u0631\u0646\u0629 \u0628\u064a\u0646 6-Spline \u0648 21-Spline: \u0645\u0631\u062c\u0639 \u0633\u0631\u064a\u0639<\/h3>\n<div class=\"table-container\" style=\"overflow-x: auto; width: 100%;\">\n<table style=\"width: 100%; border-collapse: collapse; border: 1px solid #ddd; margin: 15px 0; font-size: 15px;\">\n<tbody>\n<tr style=\"background-color: #2a5c8a; color: #fff;\">\n<th style=\"padding: 10px 12px; border: 1px solid #ddd; font-weight: bold;\">\u0645\u064a\u0632\u0629<\/th>\n<th style=\"padding: 10px 12px; border: 1px solid #ddd; font-weight: bold;\">6-Spline (1-3\/8&#8243;)<\/th>\n<th style=\"padding: 10px 12px; border: 1px solid #ddd; font-weight: bold;\">21-Spline (1-3\/8&#8243;)<\/th>\n<\/tr>\n<tr style=\"background-color: #f8f9fa;\">\n<td style=\"padding: 8px 12px; border: 1px solid #ddd; font-weight: bold;\">\u0633\u0631\u0639\u0629 \u0646\u0642\u0644 \u0627\u0644\u0637\u0627\u0642\u0629 \u0627\u0644\u0646\u0645\u0648\u0630\u062c\u064a\u0629<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">540 \u062f\u0648\u0631\u0629 \u0641\u064a \u0627\u0644\u062f\u0642\u064a\u0642\u0629<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">1000 \u062f\u0648\u0631\u0629 \u0641\u064a \u0627\u0644\u062f\u0642\u064a\u0642\u0629<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd; font-weight: bold;\">\u0642\u0637\u0631 \u0627\u0644\u062c\u0630\u0639<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">1-3\/8 \u0628\u0648\u0635\u0629 (34.9 \u0645\u0645)<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">1-3\/8 \u0628\u0648\u0635\u0629 (34.9 \u0645\u0645)<\/td>\n<\/tr>\n<tr style=\"background-color: #f8f9fa;\">\n<td style=\"padding: 8px 12px; border: 1px solid #ddd; font-weight: bold;\">\u0639\u062f\u062f \u0627\u0644\u0623\u0633\u0646\u0627\u0646<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">6 \u0623\u0633\u0646\u0627\u0646<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">21 \u0633\u0646\u064b\u0627<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd; font-weight: bold;\">\u062a\u0648\u0632\u064a\u0639 \u0639\u0632\u0645 \u0627\u0644\u062f\u0648\u0631\u0627\u0646<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">\u0625\u062c\u0647\u0627\u062f \u0623\u0639\u0644\u0649 \u0644\u0643\u0644 \u0633\u0646<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">\u062a\u0642\u0644\u064a\u0644 \u0627\u0644\u0625\u062c\u0647\u0627\u062f \u0644\u0643\u0644 \u0633\u0646<\/td>\n<\/tr>\n<tr style=\"background-color: #f8f9fa;\">\n<td style=\"padding: 8px 12px; border: 1px solid #ddd; font-weight: bold;\">\u0645\u0627\u0631\u0643\u0627\u062a \u0627\u0644\u062c\u0631\u0627\u0631\u0627\u062a \u0627\u0644\u0634\u0627\u0626\u0639\u0629<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">\u0645\u0639\u0638\u0645 \u0627\u0644\u062c\u0631\u0627\u0631\u0627\u062a (\u0642\u064a\u0627\u0633\u064a\u0629)<\/td>\n<td style=\"padding: 8px 12px; border: 1px solid #ddd;\">\u0637\u0631\u0627\u0632\u0627\u062a \u0630\u0627\u062a \u0642\u062f\u0631\u0629 \u062d\u0635\u0627\u0646\u064a\u0629 \u0623\u0639\u0644\u0649\u060c \u0648\u0645\u0639\u062f\u0627\u062a \u0623\u062d\u062f\u062b<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div style=\"text-align: center; margin: 15px 0;\"><\/div>\n<h2 style=\"font-size: 24px; color: #1a1a1a; margin: 35px 0 15px 0; border-bottom: 2px solid #2a5c8a; padding-bottom: 10px;\">\u0645\u062d\u0648\u0644\u0627\u062a Spline \u0648\u062e\u064a\u0627\u0631\u0627\u062a \u0627\u0644\u062a\u0643\u0648\u064a\u0646<\/h2>\n<p style=\"font-size: 16px; line-height: 1.8; color: #333; margin: 0 0 15px 0;\">Not every tractor-to-implement combination uses the same spline on both ends.
