🔧 Technical Specifications — Standard Agricultural Spline Profiles

The table below summarises the eight standardised spline profiles used across our PTO adaptor range. Each profile defines the female (bore) and male (shaft) geometry that the adaptor converts between.

PTO Adaptor Series 00.18.02 — Full Model Matrix

The 00.18.02 series covers conversions with 1 3/8″ Z6, 1 3/8″ Z21, 1 3/4″ Z6, 1 3/4″ Z20, and 8-32×38×6 female spline inputs. Lengths range from 140 mm to 175 mm depending on the male-female combination selected.

PTO Adaptor Series 00.18.07 — Full Model Matrix

The 00.18.07 series provides an alternative body length and coupling geometry. It shares identical spline profiles with the 00.18.02 range but features different overall lengths — notably 165 mm on select metric conversions — suited to applications where driveline clearance demands a slightly longer barrel.

⭐ Key Features & Advantages of Our PTO Shaft Adaptors

Designed for demanding agricultural and industrial environments, every adaptor in our catalogue reflects a commitment to durability, precision, and interchangeability. Here are the core reasons farmers and equipment dealers trust our PTO conversion adaptors.

🔨 Compatibility — Tractors, Implements & Industrial Equipment

Our PTO shaft adaptors are built to interface with equipment from the world’s leading manufacturers. Below is a non-exhaustive compatibility overview grouped by equipment origin and spline standard.

🛠️ Installation & Usage Guide for PTO Spline Adaptors

Step-by-Step Installation

1. Identify both spline profiles — Measure the tractor PTO stub (female end of the adaptor) and the implement input shaft (male end). Count the number of teeth and measure the major diameter to confirm the profile code (A through N).
2. Select the correct adaptor part number — Cross-reference the female and male profiles against the 00.18.02 or 00.18.07 model tables above.
3. Clean all mating surfaces — Remove old grease, dirt, and surface rust from both the PTO stub and the implement input shaft with a wire brush and solvent.
4. Apply fresh grease — Coat the female bore and male splines of the adaptor with a lithium-complex EP2 grease to reduce insertion force and minimise wear.
5. Slide the adaptor onto the tractor PTO stub — Rotate gently until the splines fully engage. Confirm the retaining pin or snap ring seats in its groove.
6. Connect the PTO driveline shaft — Slide the implement’s yoke or tube onto the adaptor’s male end, securing it with the appropriate locking collar or shear pin.
7. Reinstall the safety shield — Ensure the PTO guard covers the full length of the rotating adaptor and driveline. Never operate without a shield in place.
8. Test at low RPM — Engage the PTO at idle speed first, check for vibration or unusual noise, then gradually increase to operating RPM.

⚠️ Safety Precautions

• Always shut off the tractor engine and disengage the PTO before installing or removing an adaptor.
• Inspect the adaptor for cracks, worn teeth, or deformation before each use season.
• Never exceed the torque rating specified for the smallest spline profile in the conversion pair.
• Maintain a grease schedule — re-lubricate every 50 operating hours or at each implement changeover.
• Ensure all bystanders maintain a minimum 5-metre clearance from the rotating PTO assembly.

🌾 Typical Application Scenarios for PTO Adaptors

🌿 Broadacre Cropping — Connecting Imported Implements to Domestic Tractors

Australian grain growers frequently pair North American tractors (1 3/8″ Z6 PTO) with European air-seeders or rotary harrows that ship with 1 3/8″ Z21 involute inputs. A B-to-D adaptor (e.g., 00.18.02B*D) converts the tractor’s straight six-spline output to the implement’s twenty-one-tooth involute bore, transmitting full 540 RPM power without any shaft modification. The adaptor sits between the tractor stub and the driveline yoke, adding only 160 mm to the overall driveline length.

🌱 Hay & Forage Operations — Mixed-Fleet Mower Compatibility

Livestock producers running multiple mower-conditioners from different manufacturers often face spline mismatches when swapping implements between tractors. An E-to-G adaptor (e.g., 00.18.02E*G) allows a 1 3/4″ Z20 tractor PTO to drive a metric 8-32×38×6 mower gearbox input, eliminating the need for a dedicated driveline for each mower. This is especially valuable during peak hay season when every hour of uptime matters.

🏭 Municipal & Industrial — PTO-Driven Generators and Pumps

Council road-maintenance crews and emergency services use PTO-driven generators, water pumps, and hydraulic power units. Equipment procured from different suppliers seldom shares the same spline standard. A PTO adaptor lets a single utility tractor power any accessory in the fleet, reducing the number of spare drivelines stored on service trucks and speeding roadside deployment.

🌎 Viticulture & Horticulture — Compact Tractor Conversions

Vineyard and orchard tractors frequently run 1 1/8″ Z6 PTO stubs, yet many inter-row mowers and sprayers require a 1 3/8″ Z6 input. A B*A adaptor (e.g., 00.18.07B*A) steps the shaft down at just 140 mm overall length — short enough to fit within the tight clearance envelope of a narrow-track tractor without fouling the three-point linkage.

🚗 Transport & Logistics — PTO-Driven Refrigeration Units

Some regional cold-chain operators drive trailer refrigeration compressors directly from the tractor PTO rather than an auxiliary diesel engine. Because refrigeration units are often European-manufactured with metric spline inputs, a G-to-B or G-to-D adaptor bridges the gap, providing a quiet, fuel-efficient cooling solution for fresh-produce transport over short hauls.
