Buying farm machinery parts: wear steel, chain, tracks and hydraulics

Most of what sits in the parts category goes onto a machine you already run: steel that wears in the soil, chain that drives a header or elevator, rubber tracks, hydraulic motors and steering, and a few bolt-on assemblies for small engines, transport and the workshop. Whatever the group, a usable order starts from the host machine, its make, model and revision, the original part reference and the interface the new part has to meet. The makers below build to drawings far more often than to stock, so the drawing and the sample carry the weight of the purchase.

For soil-engaging wear steel, Ningbo Hedi Machinery forges, presses, machines and heat-treats in-house. Its boron-steel plough wear parts are hot pressed or forged, then hardened and tempered to 45–50 HRC, and are offered as a family for reversible ploughs. Pacific, the trading name of Zhejiang Huashachi Machinery, lists the ZPM1X8 in its Agriculture parts catalogue: a broad pointed working face with two mounting holes. With either supplier, agree a dimensioned drawing covering mounting holes, thickness and working profile, then approve a sample and a batch hardness report before the full order.

Agricultural chain is bought by designation. The Dongsheng CA-type chain is a family with its own size table: CA550, CA550V and CA557 at 41.40 mm pitch, CA620 at 42.01 mm, CA2060H and CA2063H at 38.10 mm and CAE44151 at 28.575 mm. Hangzhou SFR Chain Technology offers the ZGS38 combine chain with attachments at 38.0 mm pitch, 40.0 kN minimum ultimate tensile strength and 2.00 kg per metre, and the plain S62 roller chain at 41.91 mm pitch and 26.7 kN; the 62 in S62 is a chain code rather than a pitch. Zhejiang Dongsheng Chain and SFR both print breaking strength, so ask each for an allowable working load for your run and send the sprocket, joining-link and attachment drawings.

Tracks split into replacement belts and complete conversion systems, both from Jiaxing Taite Rubber. The T762A-M03P137 is a 30-inch friction-drive belt for AGCO MT700 tractors: 762 mm wide, 8839 mm long, 6-inch pitch, 116 tread bars and 58 guide lugs. For combines, the CBM25BR4 is the compact kit with a 635 mm belt and 1411 kg per side, listed for machines such as the Lovol GK120. The CBL36AR3 runs a 915 mm belt at 2245 kg and 1.8 m² contact area per side for John Deere, Case IH and Claas models, and the CBL36AR4 is its long version for the John Deere S680, S760 and S780 at 3008 mm, 2505 kg and 2.1 m². Send your combine build, axle interface and running clearances, and get the permitted axle load and installed weight back in writing.

Hydraulic parts come from Ningbo Haorui Hydraulic Transmission under the HOREY brand, which sells components rather than complete machines. Its orbital motors step up in size: BMM compact motors run from 8.2 to 50.3 cm³/rev for lawn mowers and small machines; BMR orbital motors reach 381.4 cm³/rev, and a BMR250 is rated 300 N·m on a 25 mm keyed shaft but 360 N·m on a spline or taper shaft; BMS motors sit on tapered-roller bearings for driving a wheel or sprocket directly and are rated up to 765 N·m. A ZBMR brake motor adds a multidisc brake for static holding, at 250–500 N·m depending on size. The BZZ1 steering unit is open-centre and non-reaction, from 50 to 1000 ml/rev with a 16 MPa maximum inlet, and the 1000 series hydraulic winch pulls 11.5 kN on the first rope layer and 9.0 kN on the fourth.

The remaining pages cover assemblies and support equipment. Zhejiang Yingke supplies the YK-67 rototiller assembly with a 1E44F-5 engine of 52 cc, 2.2 kW at 7500 rpm, 15.2 kg net and a 32:1 ratio. Zhejiang Joyoung Machinery offers the PGC0001 gear case for pole chainsaws, with square or 7, 9, 10 or 11-tooth shaft ends, tubes from 24 to 30 mm and a 100 mL oil tank. Zhejiang Zebang Machinery builds a two-wheel trailer underframe in rectangular and central-spine layouts, quoted against your body, towing vehicle and cargo. Jiaxing Aihua Machinery lists the AH081020 farm jack at 20 inches, lifting from 130 to 680 mm and weighing 11 kg; the rated load and manual are the first documents to request.

Prepare a category-specific sourcing brief · Read procurement guides

Compare the right fields

Read competing quotations on the same basis

Line up quotations part by part against the same host reference and the same drawing revision. For wear steel, compare material, hardness and sample approval; for chain, compare designation, pitch and the stated allowable load alongside the tensile figures; for tracks and conversion kits, compare belt width, weight per side and the adapter or frame each price includes. For HOREY motors, set the displacement, shaft, flange and ports side by side before looking at price, since the same size carries a different torque rating on a different shaft. Where a quote covers an assembly such as a winch, trailer or rototiller head, list what comes in the package and what your own machine must supply.

Questions for your supplier

• Which host models and revisions does your drawing fit, and what is the drawing revision?
• What allowable working load or pressure applies to this part in my duty, as distinct from breaking strength?
• Which adapter, frame, joining link or fittings are included in the price?
• Can you supply a sample and a batch hardness or test report before the full order?

Send these questions with your enquiry and ask for the model-specific documents in the quotation.
