サトウキビ収穫機用PTOギアボックス

Our gears are carburised and hardened to HRC 58-62, providing 3x the wear resistance of standard gears found in budget alternatives. This means longer service intervals and consistent power transfer efficiency above 97%.

Every gearbox housing is CNC-machined from high-grade cast iron, ensuring perfect gear alignment and minimal vibration. Inferior products often use sand-cast housings with loose tolerances that accelerate wear.

Our triple-lip seal design with integrated dust excluder prevents contamination ingress — a common failure point in low-cost gearboxes that use single-lip seals prone to leaking within the first season.

Optimised housing fin design and synthetic-compatible lubrication channels maintain operating temperatures 15-20°C below competing products, extending lubricant life and preventing thermal degradation of seals.

We specify bearings rated for 150% of the maximum expected load, providing a substantial safety margin. Many budget gearboxes use undersized bearings that fail prematurely under peak loads.

Strategically placed drain plugs, fill ports, and inspection covers make routine maintenance quick and simple — unlike sealed-unit competitors that require complete disassembly for oil changes.

Inspect the PTO gearbox and all supplied hardware for shipping damage. Verify the model number, gear ratio, and rotation direction match your sugarcane harvester requirements.

Clean the mounting surface on the sugarcane harvester frame thoroughly. Remove any rust, paint flakes, or debris that could prevent proper seating of the gearbox housing.

Position the PTO gearbox onto the mounting bracket. Align the bolt holes and hand-start all mounting bolts before final tightening. Use a torque wrench to tighten bolts to the specified value (typically 80-120 Nm for M12 bolts).

Connect the PTO drive shaft to the gearbox input shaft. Ensure the spline engagement is full and the locking collar or shear bolt is properly secured. Verify correct shaft length and overlap.

Connect the output shaft to the sugarcane harvester’s driven mechanism using the supplied coupling, spline adapter, or flange. Ensure proper alignment within 0.05 mm tolerance.

Fill the gearbox with the recommended lubricant (typically SAE 80W-90 GL-5 gear oil) to the level indicated on the sight glass or dipstick. Do not overfill.

Install all safety shields and guards over the PTO shaft and gearbox connections. Verify all protective covers are secure and do not contact rotating components.

Perform a low-speed test run at idle PTO speed for 5-10 minutes. Check for unusual noises, vibration, oil leaks, and proper rotation direction.

Gradually increase to full operating speed and monitor gearbox temperature with an infrared thermometer. Operating temperature should stabilise below 80°C under normal load.

After the first 50 hours of operation, re-check all mounting bolts, drain and replace the break-in lubricant, inspect seals for leaks, and verify gear mesh patterns.

Purpose: Standardising gearbox specifications across a contract farming fleet.

Customer Review: “We ordered five units for our fleet. Every one was perfectly packed, correctly specified, and delivered on time. Our mechanics were impressed with the build quality. Will order again.” — Gary Ellington, Dalby, QLD

Purpose: Fitting a new sugarcane harvester pto gearbox to a custom-built implement.

Customer Review: “First time ordering from this supplier. The gearbox exceeded our expectations — well-machined, properly balanced, and the finish quality is remarkable for the price. Repeat customer now.” — Craig Montrose, Kingaroy, QLD

Purpose: Sourcing a cost-effective replacement for an imported sugarcane harvester gearbox.

Customer Review: “After trying two cheaper alternatives that both failed within a season, we switched to this gearbox. It has now run over 1,500 hours without any issues. Quality is outstanding.” — Douglas Merrifield, Warwick, QLD

Purpose: Replacing a failed oem gearbox on a 10-year-old sugarcane harvester.

Customer Review: “The price-to-quality ratio is exceptional. We compared with European OEM parts costing 3x more and found no difference in performance after 800+ hours of operation.” — Ryan Kingsley, Gatton, QLD

Purpose: Bulk purchase of sugarcane harvester gearboxes for a machinery dealer network.

Customer Review: “Our previous gearbox overheated constantly. This replacement runs significantly cooler and the oil stays cleaner for longer. The sealing is clearly a step above the competition.” — Chris Lawson, Stanthorpe, QLD

The correct gear ratio depends on your tractor’s PTO speed (540 or 1000 RPM) and the required implement speed. For most sugarcane harvester applications, ratios between 1.5:1 and 1:2.1 are common. Our engineering team can calculate the optimal ratio based on your specific tractor and sugarcane harvester model. Contact us with your specifications for a free recommendation.

Yes, our PTO gearboxes are designed as direct replacements for major brand sugarcane harvester gearboxes. We offer matching mounting patterns, spline configurations, and gear ratios for popular models from brands like John Deere, Case IH, New Holland, and others. Provide us with your current gearbox part number or machine model for exact cross-reference compatibility.

Standard gearbox models ship within 5-7 business days from our warehouse. Custom-built gearboxes with non-standard ratios, shaft configurations, or special materials typically require 15-25 business days. We maintain extensive stock of common agricultural gearbox models for fast turnaround on urgent orders.

We recommend the first oil change at 50 hours (break-in period) to flush out metal particles from initial gear seating. Subsequent oil changes should occur every 500 hours or annually, whichever comes first. In severe-duty conditions (high temperature, dusty environments, continuous operation), reduce the interval to 250 hours. Always use the specified gear oil grade.

Yes, we offer tiered pricing for bulk orders. MOQ starts at just 1 unit for standard models, but volume discounts begin at 5 units (5-8% off), 20 units (10-15% off), and 50+ units (negotiable project pricing). OEM customers and distributors receive additional programme benefits. Request a quote for your specific volume.

All our agricultural PTO gearboxes carry a standard 18-month warranty from date of delivery, covering defects in materials and workmanship. Extended warranty options (24 or 36 months) are available for registered units. The warranty includes free replacement parts and technical support. Normal wear items (seals, lubricant) and damage from misuse or improper installation are excluded.

Absolutely. Our sugarcane harvester PTO gearbox is designed with generous safety factors (typically 2.0-2.5x rated load) to absorb the shock loads and transient peaks common in sugarcane harvester applications. The hardened gear teeth, oversized bearings, and robust housing all contribute to excellent shock load resilience. For extreme applications, we offer reinforced models with even higher ratings.

We offer models for both 540 RPM and 1000 RPM PTO systems, as well as dual-speed models that accept either input. When ordering, specify your tractor’s PTO speed so we can supply the correct gear ratio for your target output speed. Adapters for converting between 6-spline (540 RPM) and 21-spline (1000 RPM) shafts are also available.

Yes, we ship nationwide across Australia including remote and regional areas. We use established freight networks experienced in heavy agricultural equipment delivery. Standard delivery to major cities is 3-5 business days; regional areas 5-10 business days. Express freight options are available for urgent requirements.

Yes, we manufacture both PTO gearboxes and PTO shafts, so we can supply a complete, matched drivetrain assembly. This ensures optimal compatibility, correct shaft length, proper U-joint phasing, and simplified ordering. Bundled packages offer cost savings of 8-12% compared to purchasing components separately.
