What storage recommendations do you have for silage bales?

We recommend using a hay wrapper, specifically the 5080 or 7010 models, to store silage bales effectively.

AI-Powered supplier vetting

SummaryWeifang Guoan Engineering Machinery Co., Ltd. is a China-based limited company established in 2006 and associated with manufacturing, although it is also classified as a trading company. The supplier offers agricultural machinery including balers, wrappers, and mowers. It reports ISO9001:2015 certification, a professional R&D and marketing team, after-sales service, more than 10 production lines, a 7,528 m² manufacturing plant, and peak and off-peak order fulfillment within 15 working days. However, the slices contain conflicting workforce and R&D figures: one record lists 16 employees and 3 years of R&D-engineer experience, while another describes 161 employees and 23 senior research personnel. No verifiable customer cases or detailed customization examples are provided. Financial information is excluded.

Supplier typeThe supplier is identified as a limited company in China, established in 2006, and classified as a trading company while its associated industry and business scope include manufacturing and processing machinery. It presents itself as an integrated research, production, sales, and service enterprise, indicating a combined trading and manufacturing profile.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate and states that it passed ISO 9001 quality-system certification annually from 2006 to 2016. This provides direct evidence of quality-management certification, although the slices do not establish the current validity period or issuing body for the listed ISO9001:2015 certificate.

After-Sales capabilityThe company states that it has a complete after-sales service system and integrates customer needs with product development to provide after-sales service. Its stated integration of research, production, sales, and services further supports service capability, but no specific service response times, support channels, or service coverage details are provided.

R&D capabilityThe supplier reports a professional R&D team, ongoing new-product development linked to customer needs, and an integrated technology-company model. However, the workforce information is inconsistent: one slice states 23 senior research personnel and another lists total R&D-engineer experience as 3, so the scale and depth of current R&D capability cannot be confirmed precisely.

Production capacityThe supplier reports more than 10 production lines, a 7,528 m² manufacturing plant, agricultural machinery production experience, and order fulfillment within 15 working days in both peak and off-peak periods. These statements directly support production capacity and delivery capability, although the slices contain conflicting total-employee figures.

Product Q&A

Q:How to order?

After deciding to purchase, we send a proforma invoice with bank details. You can pay via T/T deposit. For a single set, the machine is ready within 7 days after deposit receipt and shipped by sea. For larger orders with handling charges, 100% payment transfer is accepted.

Q:What size of tractor is suitable for this baler?

If your tractor can lift 400kg, it operates our compact round balers. If it has 15-150 PTO HP or independent/live PTO, it can operate our compact hay balers.

Q:What are the bale dimensions and weights?

Bale dimensions are 50x70cm for model 850 and 60x70cm for model 870. Weights are 15-25kg for 850 and 20-30kg for 870. Weight is adjustable based on density.

Q:What is the production efficiency?

Efficiency ranges from 80 to 120 bales per hour, depending on the density of the bales.

Q:How is bale density adjusted?

Density is adjustable by changing the size of the sheave. We recommend storing silage bales with no more than 20% moisture.
