ツリーシェーカー用PTOギアボックス

ギアセットは、真空脱ガス処理された8620H合金鋼から製造され、浸炭処理と精密研磨によってAGMAクラス11の品質に仕上げられています。これは、ほとんどの農業用ギアボックスに見られるAGMAクラス8～9を上回る品質です。

すべての住宅設計は、共振や応力集中点を排除するために、有限要素解析（FEA）による応力解析とモード解析によって検証されます。これは、大量生産される低価格住宅には見られない、高度なエンジニアリング技術です。

当社のギアボックスは、製造当初から高性能合成潤滑油に対応しており、最大2,000時間という長時間のオイル交換間隔を実現しています。多くの競合他社は、合成油に触れると劣化するシール材を使用しています。

独自の歯車歯形改良により、最大300%の瞬間的な過負荷を損傷なく吸収します。これは、岩、切り株、または密集した作物からの突然の衝撃が発生する用途において非常に重要です。

最適化されたギア形状とベアリングの予圧設定により、-25℃から+55℃の周囲温度範囲でスムーズな動作を実現し、低温環境で動作が固くなったり騒音が発生したりする競合製品を凌駕します。

すべてのシャフトシールは、ギアボックスを作業機から取り外すことなく交換できるため、シール交換のためにギアボックス全体を取り外す必要がある設計に比べて、作業時間を大幅に節約できます。

Before installation, confirm the PTO gearbox specifications against the tree shaker’s technical manual. Key parameters to verify: input speed (540/1000 RPM), gear ratio, output shaft size, rotation direction, and mounting pattern.

Disconnect the tractor PTO shaft and secure it in the parked position. Switch off the tractor engine and remove the key. Engage the parking brake and chock the wheels.

Remove the existing gearbox if applicable. Tag and photograph all connections for reference during reassembly. Drain and properly dispose of old lubricant.

Trial-fit the new PTO gearbox to the tree shaker frame. Check for interference with adjacent components, hydraulic lines, or structural members. Shim if necessary to achieve correct alignment.

Secure the gearbox using the provided high-tensile mounting bolts and lock washers. Apply thread-locking compound (medium strength, e.g., Loctite 243) to all critical fasteners.

Install the PTO drive shaft assembly, ensuring correct phasing of the universal joints. Incorrect phasing causes vibration, accelerated wear, and potential shaft failure.

Connect the output drive to the tree shaker’s mechanism. Use new O-rings, gaskets, or seals at all connection points. Apply sealant only where specified in the installation manual.

Fill the gearbox with fresh lubricant through the filler port. Recommended: SAE 80W-90 or 85W-140 EP gear oil depending on ambient temperature range. Refer to the capacity plate on the gearbox housing.

Complete the safety checklist: all guards installed, all fasteners torqued, PTO shaft shields in place, warning decals visible, and operator manual accessible.

Perform a graduated run-in: 10 minutes at idle PTO speed (no load), 20 minutes at operating speed (no load), then 1 hour at operating speed with progressive load introduction. Monitor for any abnormalities.

Purpose: Upgrading the pto gearbox on a fleet of three tree shaker units.

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.” — Frank Beaumont, Brisbane, QLD

Purpose: Emergency replacement of a seized tree shaker gearbox during peak season.

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.” — Graham Collingwood, Melbourne, VIC

Purpose: Fitting a new tree shaker pto gearbox to a custom-built implement.

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.” — Mark Stirling, Perth, WA

Purpose: Standardising gearbox specifications across a contract farming fleet.

Customer Review: “The gearbox arrived ahead of schedule and was a perfect bolt-on fit. We had zero downtime during our busiest period. Highly recommend for any tree shaker operator.” — Neil Pendleton, Adelaide, SA

Purpose: Bulk purchase of tree shaker gearboxes for a machinery dealer network.

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.” — Derek Carrington, Toowoomba, QLD

The correct gear ratio depends on your tractor’s PTO speed (540 or 1000 RPM) and the required implement speed. For most tree shaker applications, ratios between 1:1.47 and 1:1.6 are common. Our engineering team can calculate the optimal ratio based on your specific tractor and tree shaker model. Contact us with your specifications for a free recommendation.

Yes, our PTO gearboxes are designed as direct replacements for major brand tree shaker 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 tree shaker 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 tree shaker 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.
