9YK-870 Round Hay Baler \u2014 Model Overview<\/h2>\n
The 9YK-870 Round Hay Baler<\/strong> is a trailed, PTO-driven baling machine engineered for farms and contractors that run 25\u201350 hp tractors. It picks up windrows at 800 mm width, compresses material through a fixed roll drum chamber, and delivers rope-wrapped bales measuring \u03a6630 \u00d7 700 mm \u2014 each weighing approximately 20\u201330 kg depending on crop type and moisture. At 440 kg total machine weight and an overall footprint of 1300 \u00d7 1300 \u00d7 1350 mm, it moves between plots without wide-load paperwork and connects to any Cat I drawbar in under ten minutes.<\/p>\n Buyers sourcing a round hay baler for sale<\/strong> in the compact tractor segment will find that the 9YK-870 covers the most common baling scenarios \u2014 dry grass, wheat straw, rice straw, corn stalk, alfalfa \u2014 without requiring a high-horsepower tractor fleet or specialist operators. The spring-tooth pickup feeds material directly into the compression zone, eliminating a separate auger stage and reducing the number of jam-prone transfer points.<\/p>\n OEM and private-label orders are accepted. Qualified distributors can request branded configurations, custom color schemes, and bulk packaging options. See the FAQ section below for specifics.<\/p>\n All parameters below are taken directly from the manufacturer’s certified specification sheet. Use these figures to verify tractor compatibility, bale handler fitment, and transport clearance before ordering.<\/p>\n <\/p>\n Fixed Roll Drum Chamber \u2014 Same Bale, Every Cycle<\/p>\n The compression zone measures exactly \u03a6630 mm in diameter and 700 mm wide. Because those dimensions cannot change mid-cycle, every bale that drops is the same shape and volume. Bale weight ranges from 20 kg (dry straw) to 30 kg (dense grass) depending on crop moisture \u2014 predictable enough for pallet stacking, bale spike loading, and manual handling without a front loader. Power draw stays flat across the bale cycle, which protects the tractor’s PTO shaft from surge stress, an important consideration on 25 hp machines operating near their rated output.<\/p>\n<\/div>\n<\/div>\n 800 mm Spring-Tooth Pickup with Direct Feed \u2014 No Auger Stage<\/p>\n Spring-tooth tines flex over surface irregularities rather than shearing against them, which extends tine service life on uneven ground. Material is lifted and fed straight into the compression chamber without passing through an intermediate auger \u2014 a design that removes one crop transfer point and lowers the likelihood of wrapping blockages. The 800 mm pickup width matches standard windrow widths left by common 2.5 m disc mowers after row merging, so field passes stay efficient.<\/p>\n<\/div>\n<\/div>\n Automatic Rope Wrapping System \u2014 Low Input Cost, Livestock-Safe Twine<\/p>\n When the bale reaches target density, an audible buzzer alerts the operator. The rope wrapping sequence then runs automatically at 540 rpm PTO speed, binding the bale before the rear gate opens to release it. Natural-fiber rope is the standard binding material \u2014 it biodegrades rapidly if composted and does not cause the internal lacerations that synthetic net or film twine can produce if accidentally ingested by livestock. Rope stock per 200-bale session can be carried in a standard storage box, keeping field resupply simple. This is one reason the mini round baler with rope wrapping system<\/strong> format remains dominant in smallholder markets across Asia, Eastern Europe, and Sub-Saharan Africa.<\/p>\n<\/div>\n<\/div>\n PTO Shear Bolt Overload Protection<\/p>\n The drive shaft connection includes a shear bolt that severs under torque spikes before damage reaches the baler gearbox or the tractor’s PTO clutch. Replacement shear bolts cost under USD 2 per unit and swap in under five minutes without tools. This protection is particularly valuable for operators running on uneven terrain or baling crop material with variable density, where sudden load spikes are common.<\/p>\n<\/div>\n<\/div>\n 440 kg Machine Weight \u2014 Road-Legal Transport Without Permits<\/p>\n At 1350 mm tall and 1300 mm wide, the 9YK-870 moves on public roads behind any compatible 25\u201350 hp tractor without triggering wide-load requirements in most jurisdictions. The 18 \u00d7 6.50-8-4PR tires provide adequate flotation on soft field surfaces while keeping rolling resistance low on compacted tracks. Contractors covering five or more plots per day will recognize the value of not needing a dedicated transport trailer for the baler.<\/p>\n<\/div>\n<\/div>\n <\/p>\n Designed as a round hay baler for small farm applications<\/strong>, the 9YK-870 suits operations where bale weight, machine size, and tractor horsepower need to remain within tight limits. Typical use contexts:<\/p>\n <\/p>\n This is one of the most practical questions buyers ask when switching from square to round baling. The answer depends entirely on the weight of each bale type \u2014 there is no universal number, but the calculation is simple:<\/p>\n <\/p>\n Formula: Number of square bales = Round bale weight \u00f7 Square bale weight<\/p>\n The 9YK-870 produces bales in the 20\u201330 kg range specifically because that weight bracket is manageable by one or two people without mechanical lifting equipment. This is the defining advantage of a compact round hay baler versus full-size commercial baling equipment in smallholder markets: individual bales stay within manual handling limits, cutting labor cost at the feeding end of the operation.<\/p>\n Storage density is another factor: round bales stack less tightly than rectangular bales, so a barn holding 200 square bales will store a different volume of round bales. Factor in roughly 20\u201325% lower volumetric storage efficiency for round versus square when planning storage capacity for the 9YK-870’s output.<\/p>\n <\/p>\n <\/p>\n Q1: Which tractors are compatible?<\/p>\n Any tractor rated 25\u201350 hp with a 540 rpm PTO output and Cat I drawbar hitch. This covers the majority of compact and sub-compact utility tractors sold in Asia, Latin America, Eastern Europe, and smallholder markets in Africa and Oceania. Confirm PTO shaft spline count (6-spline standard) and hitch pin diameter before finalizing the order.<\/p>\n<\/div>\n Q2: What crops can the 9YK-870 handle?<\/p>\n Designed for dry and semi-dry fibrous crops: wheat straw, rice straw, dry grass, alfalfa, corn stalk, mixed forage, and similar materials. Not intended for high-moisture silage (above ~50% moisture), which requires sealed wrapping with film to maintain anaerobic fermentation. A separate bale wrapper would be needed for silage applications.<\/p>\n<\/div>\n Q3: Is the 9YK-870 available for OEM \/ private-label supply?<\/p>\n Yes. As a compact round hay baler manufacturer for OEM supply<\/strong>, we accept branded orders with custom color specifications, logo placement, and packaging requirements. Minimum order quantities and lead times vary by configuration \u2014 contact us with your target market, annual volume estimate, and any mandatory safety certifications (CE, ISO, or local equivalents) for a formal quotation.<\/p>\n<\/div>\n Q4: What spare parts should be stocked for the first season?<\/p>\n Priority items: PTO shear bolts (primary wear item \u2014 replace after any overload event), a full set of spring-tooth pickup tines, baling rope sufficient for at least 200 cycles, and drive sprocket pins. These cover the vast majority of in-field maintenance needs and can be sourced directly from the manufacturer or through local distributors in most markets.<\/p>\n<\/div>\n Q5: What is the estimated output per hour?<\/p>\n Under typical field conditions \u2014 dry straw windrows, flat terrain, experienced operator \u2014 the 9YK-870 completes approximately 80\u2013100 bale cycles per hour at an operating speed of 2\u20135 km\/h. Output drops on steep ground, in high-moisture crops, or with very dense windrows that require slower travel to avoid pickup blockages.<\/p>\n<\/div>\n <\/p>\n Inquire About the 9YK-870<\/p>\n Tell us your tractor horsepower, target crop type, annual baling volume, and destination country. We will confirm compatibility, certifications, lead time, and FOB pricing within one business day.
