Splined Yoke 02 (Interfering Bolt) — Maximum-Security Bolt-Retained PTO End Yoke
这 Splined Yoke 02-Interfering Bolt employs a through-bolt retention system that physically interferes with the PTO shaft groove, creating one of the most secure yoke-to-shaft connections available. Unlike push pin designs that can potentially disengage under extreme vibration, the interfering bolt requires deliberate wrench removal — making it the preferred choice for high-torque, safety-critical PTO applications. Available with Z6, Z21, and metric spline bores, this versatile yoke covers both 540 RPM and 1000 RPM configurations.

⭐ 主要特点和优势
🔒 Through-Bolt Mechanical Lock
Bolt threads through yoke body into PTO shaft groove — virtually eliminates accidental disconnection under any vibration.
⚙ Triple-Spline Configuration
Z6 (540 RPM), Z21 (1000 RPM), and 8-32×38×6 metric within the same series range.
💪 Rated for Heavy Implements
Bolted connection withstands higher axial and radial loads than spring-based push pins.
🔧 Tool-Required Removal
Wrench-actuated bolt adds safety layer — no accidental separation during operation.
🔥 Hardened Bolt & Groove
Both retention bolt and shaft groove are hardened to prevent wear over years of use.
🛡 Five Variants per Series
B (Z6), D (Z21), G (8-32), C (1 3/4″ Z6), E (1 3/4″ Z20) cover every PTO standard.
🔄 兼容性信息
Fits all standard PTO output shafts: 1 3/8″ Z6 (540 RPM), 1 3/8″ Z21 (1000 RPM), 8-32×38×6 metric, and 1 3/4″ Z6/Z20 (heavy-duty 1000 RPM). Compatible with all major tractor brands including John Deere, Case IH, New Holland, Massey Ferguson, Fendt, CLAAS, and Kubota.
📚 选择指南
Step 1 — Identify Your PTO Standard: Z6 = 540 RPM standard; Z21 = 1000 RPM standard; metric 8-32 for certain European models.
Step 2 — Select Bolt Engagement: Ensure your PTO shaft has the groove for interfering bolt engagement. Most modern tractors support this.
Step 3 — Match Series to Cross Kit: A dimension determines cross kit size. Series 1 (22mm) to Series 8 (35mm).
🌾 典型应用场景
Large rotary cutters, brush hogs, stump grinders requiring maximum connection security
Hillside mowing, rough paddock operations where vibration is extreme
High-speed PTO drives for large manure spreaders, high-capacity pumps
Equipment where accidental PTO disconnection poses serious safety risks
🛠 安装和使用指南
- Select correct spline variant: Confirm B, D, G, C, or E designation matches your tractor PTO output.
- Slide onto PTO shaft: Align splines and push yoke onto tractor PTO stub shaft.
- Insert and tighten bolt: Thread the interfering bolt through the yoke body until it seats in the shaft groove. Torque to 25-35 Nm.
- Verify bolt engagement: Attempt to pull yoke off shaft — it should be completely locked.
- Assemble drive shaft: Connect cross kit, PTO tube, and implement-end yoke.
- Safety shield: Install PTO safety guard before operation.
