Every pass across the field with outdated or mismatched equipment eats into your margin. Here is what agribusiness owners tell us most often:
Conventional dot seeder and earth seeder units often overplant by 12–18%, driving up input costs by USD 20–35 per acre on high-value crops like corn and soybeans.
Standard mechanical seeder designs clog in wet soil and require frequent calibration. Operators lose up to 4–6 hours per week on adjustments instead of planting.
Uneven seed depth from poor harrow seeder integration leads to variability in emergence. Studies show this can reduce final yield by 8–14% in commercial grain production.
Oversized equipment from traditional suppliers leads to container overage charges and delayed delivery. You need a speed seeder supplier with compact, container-optimized design and reliable logistics.
🔍 These pain points cost the average 2,000-acre farm over $47,000 per season. Let’s fix that.
One integrated system that replaces three separate implements. Designed for speed seeder performance, dot seeder precision, and earth seeder reliability — all in one pass.
Patented parallel linkage keeps each easy seeder row unit at consistent depth even on rolling terrain. Uniform germination across the entire field.
Our mechanical seeder drive train handles high ground speed without skipping. Cover 120+ acres per day — 42% faster than conventional units.
Built-in harrow seeder attachment levels and firms the seedbed in one action. Eliminates an extra tillage pass — saving ~$12/acre in fuel and labor.
Quick-change metering plates for corn, soybean, sunflower, cotton, and sorghum. One earth seeder platform for your entire rotation — reduces inventory complexity.

“We switched to the Langning easy seeder system last spring. The speed seeder function alone saved us 2 days per 1,000 acres. Germination is the most uniform I have seen in 20 years. ROI in the first season.”
“The dot seeder precision is remarkable. We run at 16 km/h and the singulation stays above 98%. The integrated harrow seeder means we eliminated one pass — that is €18,000 saved annually on fuel and labor.”
“Langning’s earth seeder handled our variable soils — from clay to sandy loam — without a single depth fault. The after-sales support from the team in Shijiazhuang was exceptional. Highly recommend for large-scale operations.”
“The integrated mechanical seeder design is simple to maintain — our team learned it in half a day. We saw a 26% reduction in seed use compared to our old unit. That is huge for our cooperative.”
Our dot seeder and earth seeder platforms support corn, soybean, sunflower, cotton, sorghum, canola, and small grains. Quick-change metering plates make changeover between crops fast — typically under 20 minutes per row unit.
The integrated harrow seeder is factory-installed for optimal alignment. However, we offer retrofit kits for Langning models from 2022 onward. Contact our sales team with your serial number for compatibility check.
We ship via FCL and LCL from Tianjin port. Typical transit: 22–28 days to US Gulf Coast, 18–24 days to Rotterdam. Our speed seeder units are container-optimized to reduce freight cost. We handle all documentation and customs support.
