1BZGM Series Trailed Folding High-Speed Stubble Disc Harrow

1BZGM Series Trailed Folding High-Speed Stubble Disc Harrow – Full Product Description

The 1BZGM Series Trailed Folding High-Speed Stubble Disc Harrow is the top flagship tillage equipment developed for super-large scale farms. It provides industry-leading ultra-wide working width options from 4m to 7.5m, compatible with high-horsepower tractors from 180HP to over 300HP. It completely solves the pain point that ultra-wide mounted farm tools cannot run on public roads due to over-width during transfer, and pushes the operation efficiency of high-speed stubble cleaning to a brand new level, which is the core sharp tool for large-scale farms to seize farming time and complete ultra-large area tillage.

1. Ultra-Wide Working Width Efficiency Far Surpasses Traditional Heavy Harrows
   The maximum working width of the full series can reach 7.5m, the operating speed is stably maintained above 14km/h, the hourly tillage operation volume can easily exceed 80 mu, and the daily operation volume can easily break through 600 mu. The soil crushing and stubble cleaning effect of one single pass is completely equivalent to two passes of traditional heavy harrows, its operation efficiency is more than 3 times that of traditional heavy harrows, and the tillage cycle of ten-thousand-mu level connected large farmland can be directly cut in half.
2. Hydraulic Folding Structure for Road Legal & Safe Transfer
   The whole machine adopts hydraulic automatic folding design. The disc groups are fully unfolded to achieve ultra-wide working status during operation, while the two side disc groups automatically fold inward during transport, the overall transport width is controlled within 3m, which fully meets the road width requirements of public roads in all countries. No extra over-width transport approval is required, the transfer between different plots of the farm is very convenient, and you can directly transfer quickly without disassembling the whole machine.
3. Heavy-Duty Trailed Structure Delivers Unmatched Stability Under Extreme Conditions
   The whole machine adopts full heavy-duty trailed chassis design, equipped with large-size load-bearing transport tires as standard, the gross weight reaches 4560kg. Matched with 620/730mm diameter 6mm thickened extra-large notched discs, even under long-term full-load high-speed operation on the hardest virgin wasteland and stony hard plots, there will be no frame deformation or disc breakage, which maximizes the reliability under extreme working conditions.
4. Built-In Heavy-Duty Soil Crumble Roller Forms Perfect Seedbed in One Pass
   The rear of the machine is equipped with a 350mm diameter heavy-duty soil crumble roller as standard. After deep heavy harrowing completes powerful soil crushing and stubble cleaning, the roller further crushes and compacts the topsoil clods for leveling. It directly forms a fine, uniform, flat and moisture-retaining perfect sowing seedbed in one single field entry, no extra secondary tillage operation is needed afterwards, which drastically reduces tractor field entry times and saves a large amount of fuel cost and operation time.

Typical Applications: Ten-thousand-mu level connected tillage for super-large state-owned farms, full straw returning in large-scale agricultural reclamation areas, large-area virgin wasteland reclamation operations, deep stubble cleaning for conservation tillage in northeast China black soil region, and fast tillage operations for ultra-large area high-standard farmland.
