\n

What Is the 9YK-870 Round Baler?<\/h2>\n

\"ModelThe 9YK-870 is a professional-grade trailed round baler built for modern arable and livestock farms where reliable, consistent bale formation is non-negotiable. Mounted via a standard tractor drawbar hitch, it operates efficiently with tractors in the 25 to 50 horsepower bracket running a 540 rpm PTO output \u2014 making it genuinely accessible to smaller mixed farms as well as larger contracting operations across England, Scotland and Wales. The machine processes windrows of hay, straw, grass silage and light crop residues into compact cylindrical bales measuring 630 mm in diameter by 700 mm in width, secured with rope wrapping for easy storage and handling.<\/p>\n

At 440 kg, the 870 is robust without being unwieldy. Its roll drum compression chamber and spring-tooth pickup system work in combination to handle varying crop volumes \u2014 from thin, sparse windrows to dense, heavy swaths \u2014 at field speeds between 2 and 5 km\/h. Whether you are baling silage ahead of a wet-weather window in Yorkshire or clearing straw stubble in Lincolnshire after the combine, this round baler delivers the kind of repeatable performance that UK farmers and agricultural contractors depend on season after season.<\/p>\n<\/div>\n

\n

Why UK Farmers Choose the 870 Round Baler<\/h2>\n
\n
\n
\u2699<\/div>\n

Spring-Tooth Pickup Reliability<\/h3>\n

The 800 mm wide spring-tooth pickup gathers crop cleanly from the windrow with minimal soil contamination. Flexible tines follow ground contours naturally, reducing crop loss even on uneven terrain common in British pasture fields.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/div>\n

Roll Drum Compression System<\/h3>\n

The roll drum bale chamber ensures even crop distribution and uniform bale density from the core outward. This produces consistently shaped bales that stack securely and feed evenly in livestock ration systems \u2014 a critical factor for dairy and beef units.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/div>\n

Low Horsepower Compatibility<\/h3>\n

With a matching power range of just 25 to 50 hp, the 870 pairs naturally with compact and mid-range tractors already common on British smallholdings and family farms. No expensive high-horsepower upgrade required \u2014 your current machine likely qualifies.<\/p>\n<\/div>\n

\n
\ud83d\udce6<\/div>\n

Compact Transport Dimensions<\/h3>\n

The 1300 \u00d7 1300 \u00d7 1350 mm overall footprint means the 870 navigates narrow farm lanes and tight gateways without difficulty. Road transport between fields or to other farm sites is straightforward \u2014 no wide-load permits required in most scenarios.<\/p>\n<\/div>\n

\n
\ud83d\udd17<\/div>\n

Rope Wrapping Simplicity<\/h3>\n

Rope wrapping keeps consumable costs predictable and maintenance demands low. The wrapping mechanism is straightforward to thread and adjust in the field, reducing downtime during critical harvesting windows when every dry hour counts.<\/p>\n<\/div>\n

\n
\ud83d\udee0<\/div>\n

Durable Structural Build<\/h3>\n

Constructed from high-tensile structural steel throughout, the 870 frame withstands the mechanical stresses of repeated high-density baling cycles over many seasons. Key wear components \u2014 tines, rollers and wrapping guides \u2014 are designed for straightforward replacement, keeping lifecycle costs manageable.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

How the 870 Round Baler Works<\/h2>\n

Power is transferred from the tractor’s 540 rpm PTO shaft through a driveline to the machine’s internal mechanism. As the tractor moves forward at between 2 and 5 km\/h, the 800 mm spring-tooth pickup lifts the crop windrow off the ground and feeds it directly into the compression chamber \u2014 a design called direct feed by spring tooth, which eliminates the transfer auger found on some older designs and reduces the number of moving parts that can wear or block.<\/p>\n

Inside the roll drum bale chamber (700 mm wide, 630 mm diameter), a series of driven rollers rotate the incoming crop continuously. Centrifugal force and roller contact compact the material progressively from the outer surface inward, building up a firm, dense cylinder. When the bale reaches the target diameter of 630 mm, the operator initiates the wrapping cycle. Sisal rope is automatically wrapped around the circumference several times to secure the bale, then the rear gate opens and the finished bale rolls gently onto the ground.<\/p>\n

The simplicity of this rolling compression principle is exactly why round balers have remained the preferred choice for UK hay and straw contractors for decades. Fewer hydraulic components than variable-chamber machines means fewer potential failure points, and the consistent bale geometry makes handling with a bale spike or loader bucket entirely predictable.<\/p>\n<\/div>\n

Where the 870 Round Baler Performs<\/h2>\n

\"Round<\/p>\n

The 870 handles a wider range of crop types and conditions than its compact specification might suggest. In the lowland mixed farming belts of the East Midlands and East Anglia, contractors use it to clear barley and wheat straw swiftly after harvest, keeping fields clean for the following rotation. Upland sheep and beef farmers in Wales and the Scottish Borders rely on it for baling ryegrass hay and silage across sloping fields where heavier machinery would cause compaction damage or risk tipping.<\/p>\n

Equestrian businesses throughout the Home Counties have found the 870 particularly well-suited for producing small hay bales that are easy to handle, move and store in yard environments. The 630 \u00d7 700 mm bale size is light enough for two people to roll comfortably and compact enough to stack in a standard stable block without specialist handling equipment.<\/p>\n

Customer Success: Bramblewood Farm, Shropshire, UK<\/h2>\n

Livestock & Hay Operation | West Midlands, England<\/p>\n

\n

Bramblewood Farm runs a 180-head suckler beef herd across 320 acres of Shropshire pasture and arable ground. Prior to purchasing the 870 Round Baler, the operation relied on a contractor to bale approximately 600 acres of hay and straw annually \u2014 an arrangement that proved costly and schedule-dependent. After buying the 870 and pairing it with their existing 42 hp compact tractor, the farm now completes all its own baling over a two-week window in July and a further week in September for silage aftermath. First-year savings on contractor fees covered a significant portion of the machine purchase price. The farm manager noted that the spring-tooth pickup handled a late-cut, slightly stemmy ryegrass sward better than expected, producing tight, well-formed bales throughout.<\/p>\n

Perguntas frequentes<\/h2>\n
\n
\nWhat is the cost of a round baler suitable for a small farm in England and where can I get a price quote?<\/summary>\n
The price of the Model 9YK-870 Round Baler varies depending on configuration, shipping destination within the UK, and order quantity. For small farms in England looking for an affordable entry point, the 870’s 25\u201350 hp compatibility keeps total cost of ownership low.

\nWhich round baler is best for a UK dairy farm baling first-cut silage with a 40 horsepower tractor?<\/summary>\n
The 9YK-870 is well-matched to this scenario. Its 25\u201350 hp power range covers a 40 hp tractor comfortably, and the roll drum compression chamber handles the dense, moisture-heavy material typical of first-cut silage. The rope wrapping system secures the bale for immediate wrapping with a separate stretch-film wrapper. If you want to avoid a two-machine process, our M\u00e1quina integrada de enfardamento e embalagem 9YCM-850<\/a> may be worth considering.<\/div>\n<\/details>\n
\nHow does a round baler work and what type of crops can it handle on a mixed arable farm in Yorkshire?<\/summary>\n
A round baler picks up a crop windrow using a rotating pickup reel, feeds it into a compression chamber where rollers compact the material into a cylindrical bale, then wraps the finished bale with rope or net before ejecting it. On a mixed arable farm in Yorkshire the 870 handles winter wheat straw, spring barley straw, oilseed rape straw and ryegrass hay without issue. It is not designed for green maize silage; for that crop a specialist forage harvester and separate wrapper is the industry-standard approach.<\/div>\n<\/details>\n
\nWhere can I find a reliable round baler supplier in the UK that also offers custom specifications for my agricultural contracting business?<\/summary>\n
square-balers.com supplies the 870 Round Baler directly to UK agricultural contractors, offering custom configuration options including alternative pickup widths, modified hitch arrangements and OEM builds. Contracting businesses with multi-unit requirements benefit from volume pricing and priority technical support. Contact sales@square-balers.com<\/a> to discuss your specific operational needs and receive a bespoke quotation.<\/div>\n<\/details>\n
\nWhen is the best time to service a round baler before the UK hay season and what maintenance does it require?<\/summary>\n
The ideal time to service the 870 is during April or early May, giving you a full run-in period before peak June and July hay making. Key pre-season checks include: inspecting and replacing worn spring tines, greasing all driveline and roller bearings, checking PTO shaft universal joints for play, confirming the rope wrapping mechanism threads correctly, and examining tire pressures (18 \u00d7 6.50-8-4PR). Replacing consumables before the season rather than during it eliminates the risk of downtime when weather windows are critical.<\/div>\n<\/details>\n
\nWhat bale size does the 9YK-870 produce and is it the right dimensions for transporting hay bales by road in the UK?<\/summary>\n
The 870 produces bales of 630 mm diameter by 700 mm width. This is a compact round bale format \u2014 considerably smaller than the 1.2 m or 1.5 m diameter large round bales produced by high-capacity contractors’ balers. For road transport, eight to twelve of these bales typically fit on a standard flat-bed trailer within normal UK road width limits. The bale weight, which depends on crop type and density, is generally within the range manageable by a tractor loader with a standard bale spike, making farm-to-farm movement straightforward.<\/div>\n<\/details>\n<\/div>\n
