KYBOLT PTO Drive Shaft 1 3/8" PTO Shaft, vs 31.5"-41" PTO Shaft, 1-3/8" PTO Drive Sh
Quick Verdict
The KYBOLT PTO Drive Shaft is the better value for most buyers, offering the same 1 3/8" diameter and 6-spline ends as the PTO brand for $41 less. However, the PTO brand’s adjustable length range (31.5"-41") gives it a clear advantage for applications requiring a longer or more custom fit. Choose KYBOLT for standard, fixed-length needs; choose the PTO brand if you need length adjustability.

Where KYBOLT Wins
Price. At $89.37, the KYBOLT is $41.40 cheaper than the PTO brand—a 31% savings. For budget-conscious buyers or those replacing a standard shaft, this is a significant difference.
Review volume. With 58 reviews versus 16, the KYBOLT has a larger sample size supporting its 4.5-star rating. This suggests more consistent performance across a wider range of users and equipment.
Round end design. The “round end” on the KYBOLT may provide a more secure fit in certain PTO yokes or applications where a round profile is preferred over a fully splined end. This can reduce wobble or vibration if your implement’s yoke is designed for a round-end shaft.
Fixed length simplicity. If your mower or implement has a fixed distance between the tractor PTO and implement input, a non-adjustable shaft eliminates the risk of improper adjustment or slippage. It’s a set-and-forget solution.
Where PTO Wins
Adjustable length range. The PTO brand’s 31.5" to 41" range is its standout feature. This flexibility allows it to fit a wider variety of tractors and implements—especially useful if you swap between different attachments or have a non-standard hitch setup.
Both ends splined. The “6 spline both ends” design means both the tractor and implement sides have full spline engagement. This can provide more uniform torque transfer and reduce wear on the shaft ends, particularly in high-torque applications.
Longer maximum length. At 41" fully extended, the PTO brand can reach longer distances than the KYBOLT (whose max length isn’t stated but is presumably shorter). This is critical for offset mowers, rear-mounted PTO implements, or tractors with longer hitches.
Fewer compatibility issues. The adjustable length and dual spline ends make the PTO brand a safer bet for older or less common equipment where fixed-length shafts may not fit.
Which Should You Buy
Buy the KYBOLT if: You need a standard, fixed-length 1 3/8" 6-spline PTO shaft for a mower or implement with a known, consistent distance between PTO connections. You want to save $41 and benefit from a proven product with many reviews. The round end is fine for your yoke.
Buy the PTO brand if: You need an adjustable shaft to fit multiple implements or a tractor with a non-standard hitch. You require a longer shaft (up to 41") or prefer both ends fully splined for maximum torque transfer. You’re willing to pay
