Zhejiang Sifang Group Co., Ltd.
浙江四方集团有限公司
Zhejiang Sifang Group, based in Yongkang, builds diesel engines, tractors and harvesters for mechanised rice production. Its best-documented machine is the GN151 single-axle walking tractor, sold with a traction frame or a rotary tiller. For a walking-tractor order, specify the full working package and name the Sifang company that will sign the contract.
Which Sifang company sells to you
The official introduction names Zhejiang Sifang Group Co., Ltd. and describes Zhejiang Sifang Co., Ltd., Zhejiang Sifang Import & Export Co., Ltd. and an agricultural machinery R&D institute inside the group. That explains why several company names appear across the website. The contact address is Sifang Road in Yongkang, Zhejiang.
Ask for a quotation that names the seller, the manufacturer, the company receiving payment and the company responsible for after-sales service. The machine label, conformity documents and parts documents should carry the matching names. Production duties and export terms can differ between subsidiaries, so confirm them for the company you contract with.
[1][3]The range by field operation
Sifang presents its machinery as a route through rice production. The product centre splits into power machinery, cultivation machinery, harvesting machinery, intelligent agricultural machinery and implements. It also has a gas-stove category, which sits outside farm machinery. Request a model sheet for any machine you consider in these groups. On the power-machinery side, the Ningben NY504 Tractor and the Xinglaihe TB404-A9 / TB404-H1 Tractor are two wheeled tractors from other makers to price alongside Sifang's.
[1][2][3]Power and cultivation
Choose between the GN151 walking tractor and a separate tractor family. The catalogue also shows SFG902 crawler machinery; check that model on its own page.
Harvesting
The category covers full-feed combine harvesters. Ask for the current model and the crop conditions it suits before comparing harvest performance or field access.
Implements
Specify the plough or rotary-tiller package with its mounting, working dimensions and drive. Ask Sifang to confirm in writing which attachments fit the GN151.
Models and specifications
Quote the exact model, configuration and operating conditions together, and ask the factory to confirm current availability.
Sifang GN151 Walking Tractor
Catalogue reference: GN151
The Sifang GN151 is a single-axle walking tractor for powered and traction work. Sifang lists a 1100-series diesel engine rated 11.03 kW at 2200 rpm, six forward and two reverse gears, and rubber or iron wheels with adjustable track. It comes with a traction frame (351 kg structural weight) or a rotary tiller (472 kg), and works with single or double plough shares. Choose the wheels, track setting, implement, starting version and transmission input first, then compare prices on that exact package.

GN151: frame or tiller changes size and weight
Sifang's GN151 sheet gives separate figures for the traction frame and the rotary tiller. It lists structural weight apart from operating mass, and gives track ranges for rubber and iron wheels. The overview offers chain or gear input; the detailed table describes the chain version. Ask for the sheet that matches the option you are quoted.
[3]| GN151 configuration | What it means for your order |
|---|---|
| Traction frame: 2340 × 980 × 1240 mm; 351 kg structural weight | The basic configuration. Use these figures for the frame version only. |
| Rotary tiller: 2950 × 980 × 1240 mm; 472 kg structural weight | Check turning room at row ends, moving and handling with the tiller fitted. |
| Minimum operating mass 371 kg; tiller plus seat entry 492 kg | Operating mass includes oil and water. Ask whether the seat is in your price and get the safe operating instructions for the seated version. |
| Rubber-wheel track 570–810 mm; iron-wheel track 850–1090 mm | Track is measured between wheel centres; overall width is larger. Choose wheels and track setting to suit your field layout. |

Production steps you can ask to inspect
Sifang describes a route from casting and machining through heat treatment, stamping, welding, coating and assembly. It also lists tractor, diesel-engine and harvester R&D functions and measuring and testing facilities. Annual capacity and export-ranking figures from the introduction are left out; ask Sifang for current output and lead time. Use the checkpoints below on a factory visit or in your inspection plan.
[1][3]Components
Ask for traceability of the quoted engine and transmission parts and which of them Sifang makes itself.
Machined and heat-treated parts
Ask for the inspection points on your assembly, including dimensional checks and any heat-treatment records.
Final assembly
Agree a record for each machine covering configuration, controls, brakes, leaks and implement drive, following Sifang's own test procedure.
Dispatch
Check serial labels, engine version, wheel set, implement, manuals and parts list against the purchase specification.
Crawler-tractor standard revision plan
China's national standards information service lists Zhejiang Sifang Group Co., Ltd. among the drafting organisations for revision plan 20253998-T-604, Agricultural tractors, General requirements, Part 4: Crawler tractors. When checked, the plan was still under review.
The plan concerns crawler tractors, while the GN151 runs on a single axle and is steered on foot. For the model you order, ask Sifang for its own conformity and test documents.
[4][3]Field trial and after-sales support
The GN151 sheet gives different working dimensions for ploughing and rotary cultivation, travel speeds for each gear and rotor speeds that change with the sprocket set. Decide the job first, then compare engine power. For a sample trial, record the implement, wheels, track setting, transmission input, engine version and operating mass, and run the machine in your soil under Sifang's safe procedure.
The group website has a dealer search. Ask Sifang which dealer or service partner will support your configuration in your country, and request an engine and tractor parts list, a manual in your language and the written warranty. Agree service response time, spare-parts stock and delivery lead time in the contract.
