干草耙动力输出齿轮箱

Our gears utilise 20CrMnTi alloy steel with case-hardening to ensure a surface hardness of HRC 58-62 while maintaining a tough, ductile core — far superior to the mild steel gears found in inferior products.

The fully sealed gearbox housing achieves IP65-rated protection against dust and water jets, ideal for Australia’s harsh outback conditions. Budget alternatives often lack proper sealing and fail in dusty environments.

Computer-optimised gear tooth profiles achieve power transmission efficiency above 96%, reducing fuel consumption and heat generation compared to poorly designed alternatives that waste 10-15% of input power as heat.

While our upfront cost is 15-25% higher than budget options, the extended service life (10,000+ hours vs 3,000 hours typical) and lower maintenance requirements deliver 40-60% savings over the equipment lifecycle.

Multi-layer surface treatment including zinc phosphate primer and epoxy topcoat provides excellent corrosion resistance in humid coastal environments, salt spray exposure, and chemical contact from fertilizers.

Our modular gearbox platform allows field-swappable gear sets for different ratio configurations, reducing inventory costs for dealers and enabling quick adaptation to different implements.

Unpack the PTO gearbox and cross-reference the nameplate data with your order specifications. Confirm the gear ratio, input/output shaft dimensions, and rotation direction are correct for your hayrake.

Prepare the hayrake mounting interface by removing the old gearbox (if replacing) and cleaning all mating surfaces. Inspect mounting holes for thread damage or elongation.

Apply a thin film of anti-seize compound to the mounting bolt threads and the gearbox-to-frame mating surface. This prevents corrosion-bonding and facilitates future maintenance.

Lift the gearbox into position using appropriate lifting equipment (typical weight 25-80 kg depending on model). Never attempt to manually handle heavy gearbox units.

Insert and hand-tighten all mounting fasteners in a star pattern. Then torque to specification in two passes: first to 60% of final torque, then to 100%. Typical values: M10 = 50 Nm, M12 = 85 Nm, M16 = 210 Nm.

Attach the PTO drive shaft to the input spline. The shaft should slide freely onto the spline with no binding. If resistance is felt, check for burrs, misalignment, or incorrect spline count.

Connect the gearbox output to the hayrake’s working element. Verify rotational alignment using a dial indicator if precision coupling is required. Maximum allowable angular misalignment: 1°.

Add the specified lubricant type and quantity. For most models, fill to the centre line of the sight glass with the gearbox in its normal operating position.

Reinstall all PTO shaft guards, gearbox covers, and safety decals. Ensure 360° coverage of all rotating components within operator reach.

Commission the gearbox by running at no-load for 15 minutes, then gradually introducing load over 2 hours. Record baseline temperature and vibration readings for future comparison.

目的： Equipping a new hayrake with a high-performance pto gearbox.

客户评价： “我们为车队订购了五台设备。每台设备包装完美，规格完全正确，并且按时交付。我们的维修技师对设备的制造质量赞不绝口。以后还会再次订购。” — Michael O’Brien, Geraldton, WA

目的： Emergency replacement of a seized hayrake gearbox during peak season.

客户评价： “我们之前的变速箱经常过热。这款替换后的变速箱运行温度明显降低，而且油液能保持更长时间的清洁。其密封性能也明显优于同类产品。” — Chris Lawson, Esperance, WA

目的： Sourcing a cost-effective replacement for an imported hayrake gearbox.

客户评价： “After trying two cheaper alternatives that both failed within aseason, we switched to this gearbox. It has now run over 1,500 hours without any issues. Quality is outstanding.” — Craig Montrose, Kalgoorlie, WA

目的： Replacing a failed oem gearbox on a 10-year-old hayrake.

客户评价： “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 hayrake operator.” — Alan Davenport, Albany, WA

目的： Bulk purchase of hayrake gearboxes for a machinery dealer network.

客户评价： “性价比非常出色。我们将其与价格高出三倍的欧洲原厂配件进行了比较，发现经过 800 多个小时的运行后，性能没有任何差异。” — Tony Marlborough, Bunbury, WA

The correct gear ratio depends on your tractor’s PTO speed (540 or 1000 RPM) and the required implement speed. For most hayrake applications, ratios between 1.47:1 and 1:1.9 are common. Our engineering team can calculate the optimal ratio based on your specific tractor and hayrake model. 联系我们 请提供您的具体要求，我们将免费为您提供建议。

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

标准型变速箱可在 5-7 个工作日内从我们的仓库发货。定制型变速箱，例如采用非标准传动比、轴配置或特殊材料的变速箱，通常需要 15-25 个工作日。我们备有大量常用农用变速箱型号的库存，可快速响应紧急订单。

我们建议在运行 50 小时（磨合期）后进行首次换油，以清除齿轮初始磨合过程中产生的金属颗粒。之后，应每 500 小时或每年换油一次，以先到者为准。在严苛工况（高温、多尘环境、连续运行）下，换油间隔应缩短至 250 小时。务必使用指定等级的齿轮油。

是的，我们为批量订单提供阶梯式定价。标准型号的最低起订量仅为 1 台，但批量折扣从 5 台起（5-8% 型号优惠），20 台起（10-15% 型号优惠），50 台以上起（项目价格可协商）。OEM 客户和分销商可享受额外的项目优惠。 索取报价 根据您的具体需求量。

Absolutely. Our hayrake 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 hayrake 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.
