Choosing a wood chipper starts with the material you need to process, not with the largest number in a catalog. For an overseas buyer, the useful questions are straightforward: what is the largest branch diameter, how much material must the machine handle, which power source is practical at the work site, and will the packed machine fit your shipping plan?

1. Start with maximum branch diameter

Use the maximum branch diameter as the first filter. CHENYANG lists the CY-150B for branches up to 60 mm, the CY-200B for up to 100 mm, and the CY-300A and CY-300B families for up to 120 mm. The CY-500A is listed at 130 mm, while the CY-500B is listed at 150 mm. These are different application bands, so a buyer should compare the feed material with the stated maximum before comparing engines or accessories.

Capacity is not the same as a promise that every load will process at the same speed. The product pages describe the working-efficiency figures as theoretical data and say that the physical product prevails if there is a discrepancy. Treat the diameter and output figures as a specification starting point, then confirm the exact configuration with the factory.

2. Use theoretical output to size the workflow

The CY-150B is listed at a theoretical 1,000–1,300 kg/h, and the CY-200B at 1,200–1,600 kg/h. The CY-300A and CY-300B models are listed at 1,500–1,800 kg/h. The CY-500 pages specify maximum cutting diameter, rated power and cutter-disc details but do not list a comparable working-efficiency range. That is useful purchasing discipline: compare only figures that the source data actually gives.

For a distributor or contractor, output should be considered alongside handling. A smaller machine may be the better match when the incoming branches are within its range and the machine will be moved frequently. A larger model may be relevant when the material routinely approaches the higher diameter band. Ask for the current quotation and configuration confirmation before presenting a throughput figure to an end customer.

3. Match the engine to the destination and job site

Most CY-150B, CY-200B, CY-300A and CY-300B listings include petrol, diesel, three-phase electric and Honda options. The CY-150B data identifies petrol 170F, diesel 173F / 178F, a three-phase 4.5 kW motor and Honda GX160. The CY-200B and CY-300 listings identify petrol 192F, diesel 192F / 195F, a three-phase 7.5 kW motor and Honda GX390.

Check local fuel and service preferences, confirm whether three-phase power is available, and ask which engine-start configuration is included. The data distinguishes manual/electric start on the listed petrol and Honda options in these ranges. Do not assume that an engine option on one family carries across every model; confirm the exact model before ordering.

For a first quotation, state the preferred power category rather than simply asking for a “standard engine.” This keeps the comparison tied to the exact product record. A buyer can then check whether the selected fuel or electric arrangement suits the intended site and whether the listed starting method is appropriate for the operator.

4. Check hopper size, mobility and discharge

Feed opening dimensions affect how the operator approaches the material. The CY-150B lists a 500 × 530 mm hopper, the CY-200B 520 × 580 mm, and the CY-300B self-propelled model 580 × 620 mm. Several CY-300A and CY-300B configurations list twin discharge with an upper chute and lower outlet. The CY-150B bottom-discharge version lists bottom discharge instead.

Mobility is another clear differentiator in the data. The CY-300A range includes towable, wheeled, reverse-feed and tracked remote-control configurations. The CY-300B listings include a self-propelled version with a listed travel speed of 6 km/h and a towable version. Choose the mobility layout that matches the site, then verify loading, towing and destination requirements with the quotation.

These details also help with site planning. A tracked configuration has different packed dimensions and mass from the gasoline or towable versions, while a self-propelled machine has a listed travel speed. Treat the hopper, discharge and mobility lines as configuration details to confirm, not as interchangeable features across the whole CY range.

5. Do not leave packing to the end

For export buying, packed dimensions and net weight belong in the first inquiry. Examples in the product data include 110 × 60 × 120 cm and 130 kg net for the CY-150B, 110 × 62 × 120 cm and 195 kg net for the CY-200B, and 122 × 72 × 110 cm and 195 kg net for the CY-300A towable version. The tracked CY-300A is listed at 170 × 100 × 140 cm packed and 300 kg net.

Send the model, branch diameter, preferred power, destination and packing question in one message. The wood chipper catalog links each model to its full specification page, and the contact page provides the inquiry route. You can also message CHENYANG on WhatsApp with the same details.
