Choosing the right \u062d\u0635\u0627\u062f\u0629 \u0627\u0644\u0630\u0631\u0629<\/strong> is less about buying the biggest machine and more about matching the number of harvesting rows to your field size, your harvest window and the power you already own. A machine that is too small will not finish before the rain comes; a machine that is too large costs more to buy, burns more fuel and cannot turn on narrow headlands.<\/p>\n\n\n\n

This guide compares 1-row, 2-row and 3\/4-row corn harvesters<\/strong> side by side, using the real working specifications of our 4YZ-1 walk-behind harvester, the 2-row self-propelled harvester and the 4YZ-3W \/ 4YZ-4W series \u2014 the same data our sales engineers use when a customer in Nigeria, Pakistan or Peru asks which machine they need.<\/p>\n\n\n\n

Daily figures above assume an 8-hour day. The 1-row figure comes from a skilled operator working a full 10-11 hour day at the higher end of the 0.72-1.44 km\/h working speed range, which is how our customers in hilly areas actually run the machine.<\/p>\n\n\n\n

Why Row Count Is the First Decision<\/strong><\/h2>\n\n\n\n

1-Row Corn Harvester: Small Plots, Hills, One Machine Many Jobs<\/strong><\/h3>\n\n\n\n

\u0627\u0644 1 \u0635\u0641 \u062d\u0635\u0627\u062f\u0629 \u0627\u0644\u0630\u0631\u0629<\/a> is a walk-behind machine: 265 kg, 1,820 \u00d7 800 \u00d7 1,190 mm, powered by a 188F gasoline engine or an air-cooled diesel engine. It picks the ears into a 30-50 ear collection box and crushes the stalk back into the field in the same pass, leaving a stubble height from 10 cm. On steep or terraced ground where a ride-on machine cannot enter, this is often the only mechanical option \u2014 and when the harvest is over, the harvesting unit can be removed so the same power unit works as a rotary tiller for deep tillage and ridging.<\/p>\n\n\n\n

It is also the cheapest machine to ship: 26 units fit in a 20GP container and 63 in a 40GP, which is why first-time buyers and dealers often start with a full container. Our UK distributor’s very first order in December 2018 was a 20GP of these machines, resold into Africa \u2014 and an American customer bought the same 1-row platform as a corn picker.<\/p>\n\n\n

2-Row Corn Harvester: The Workhorse for Mid-Size Farms<\/strong><\/h3>\n\n\n\n

\u0627\u0644 \u0622\u0644\u0629 \u062d\u0635\u0627\u062f \u0627\u0644\u0630\u0631\u0629 2 \u0635\u0641\u0648\u0641<\/a> is self-propelled and ride-on: a 45 HP (34 kW) four-cylinder water-cooled diesel, 4,850 \u00d7 1,450 \u00d7 2,600 mm, 1,135 mm cutting width. One operator harvests 0.15-0.3 hm\u00b2 per hour with fuel use under 25 kg per hectare. Eight sets of spiral rubber husking rollers peel the ears automatically, a hydraulic lift tips the ears into the recovery box, and the stalk is crushed across a 930 mm width behind the machine.<\/p>\n\n\n\n

This is the size where manual husking stops making economic sense, but a large combine is still out of budget. It is the model we have shipped twice as full 40HQ containers to a returning customer in Pakistan, plus orders to Indonesia, the Philippines and South Africa.<\/p>\n\n\n

3\/4-Row Corn Harvester: Commercial Scale, Planted Rows or Not<\/h3>\n\n\n\n

\u0627\u0644 3 rows and 4 rows corn harvester machine<\/a> series (4YZ-3W \/ 4YZ-4W) is built for farms and cooperatives that must finish quickly: 103 kW self-propelled, 1,825 mm cutting width for the 3-row and 2,400 mm for the 4-row, a 1.5 m\u00b3 or 2.2 m\u00b3 grain tank, and husking, ear picking and stalk crushing done in one pass. A practical advantage on real farms is that the machine can harvest without following the planted rows \u2014 uneven planting or replanted strips do not stop work.<\/p>\n\n\n\n

Published performance: total loss rate \u22644%, grain breakage \u22641.0%, impurities \u22641.5%, husking rate \u226585% and straw crushing \u226585%, with fuel consumption \u226420 L per hectare and stubble height \u226450 mm. These are the numbers to compare against any competing quotation \u2014 not the brochure adjectives.<\/p>\n\n\n\n

Match Field Capacity to Your Harvest Window<\/strong><\/h2>\n\n\n\n

Count backwards from your deadline: hectares to harvest \u00f7 days you can work \u00f7 8 hours = the capacity per hour you must buy. Add 20-30% margin for turning at headlands, grain tank unloading and breakdowns, because a machine running at 100% of its rated capacity every hour is not realistic.<\/p>\n\n\n\n

How to Read the Performance Numbers<\/strong><\/h2>\n\n\n\n
    \n
  • \u0625\u062c\u0645\u0627\u0644\u064a \u0645\u0639\u062f\u0644 \u0627\u0644\u062e\u0633\u0627\u0631\u0629<\/strong> \u2014 ears and kernels left in the field. 4% on a 3\/4-row machine means 96 out of 100 ears reach the grain tank; on 50 hectares that difference is money.<\/li>\n\n\n\n
  • \u0645\u0639\u062f\u0644 \u0643\u0633\u0631 \u0627\u0644\u062d\u0628\u0648\u0628<\/strong> \u2014 cracked kernels. Keep it at or below 1% if you sell grain, because broken kernels spoil faster and millers discount them.<\/li>\n\n\n\n
  • \u0645\u0639\u062f\u0644 \u0627\u0644\u0634\u0648\u0627\u0626\u0628<\/strong> \u2014 stalk pieces and soil mixed with the ears. Below 1.5% saves a screening step at the threshing or grinding stage.<\/li>\n\n\n\n
  • Husking rate<\/strong> \u2014 share of ears peeled clean by the husking rollers (8 sets of spiral rubber rollers on the 2-row, iron plus rubber on the 3\/4-row). 85% and above means less manual sorting afterwards.<\/li>\n\n\n\n
  • Fuel consumption per hectare<\/strong> \u2014 \u226420 L\/ha on the 3\/4-row, under 25 kg\/ha on the 2-row, \u226410 kg\/ha on the 1-row. Fuel is the largest running cost you can calculate before buying.<\/li>\n\n\n\n
  • Field speed, turning radius and ground clearance<\/strong> \u2014 2.2-5.0 km\/h and a 7,000 mm turning radius on the 2-row, 290\/280 mm clearance on the 3\/4-row. These decide whether the machine is workable on your headlands and sloping ground.<\/li>\n<\/ul>\n\n\n\n

    Walk-Behind or Self-Propelled?<\/strong><\/h2>\n\n\n\n

    The 1-row machine is walk-behind: an operator walks behind it, and the whole unit costs little because there is no cabin, no hydraulic drive axle and no trailer. The 2, 3 and 4-row machines are self-propelled: the engine drives travel, hydraulics and the header together, so one seated operator replaces a crew of 8-10 people husking by hand. Self-propelled costs more to buy and to ship \u2014 a 2-row travels 1-2 units per 40HQ \u2014 but it is cheaper per hectare from roughly the first full season onwards.<\/p>\n\n\n\n
