9YK-870 Round Baler
Compact, Reliable & Built for British Farms
The Model 9YK-870 round baler delivers consistent, high-density bales from a compact trailed unit. Designed to match tractors from 25–50 hp, it handles grass, straw, and mixed forage across the varied terrain of UK arable and livestock farms.
What Makes the 9YK-870 Round Baler a Smart Choice for UK Farmers?
Across England, Scotland, Wales, and Northern Ireland, farm contractors and owner-operators face a shared challenge: getting hay and silage baled quickly and cost-effectively without the overhead of a large high-horsepower machine. The 9YK-870 round baler was engineered precisely for this market gap. Its trailed design, spring-tooth pick-up system, and roll drum compression chamber make it exceptionally well-suited to smaller British field parcels and mixed livestock operations where versatility matters as much as throughput.
Unlike full-size round balers that demand tractors in the 80–120 hp range, this model pairs comfortably with tractors as modest as 25 hp, making it accessible to smallholders and hill farmers who may not want to invest in heavy machinery just to manage seasonal baling cycles. The bale produced — 630 mm in diameter and 700 mm wide — is manageable for manual handling, stack storage, and wrapping with most standard wrapper units, including the 9YCM-850 silage baler wrapper combo.
At only 440 kg, the round baler is light enough to be trailered without specialist transport and can be towed between fields or to neighbouring farms with minimal fuss — a real advantage for agricultural contractors covering multiple sites across a single county.
Core Advantages at a Glance
⚡
Low Tractor Power Requirement
Operates efficiently with tractors from 25 to 50 hp at a PTO speed of 540 rpm — ideal for the compact utility tractors common on British smallholdings and hill farms without demanding a machinery upgrade.
🌿
Spring-Tooth Pick-Up System
The spring tooth pick-up directly feeds crop material into the compression chamber without a separate conveyor stage. This reduces mechanical complexity, lowers maintenance requirements, and keeps the crop flow smooth even in damp or tangled windrows typical of UK autumn cuts.
🛠
Roll Drum Compression Chamber
A roll drum-type bale chamber (700 mm wide, 630 mm diameter) applies consistent radial pressure around the growing bale core. The result is a uniformly dense, weather-resistant round bale that holds its shape through storage, transport, and wrapping — critical for minimising fermentation loss in silage applications.
📚
Rope Wrapping — Simple & Reliable
Rope wrapping is straightforward to load, less prone to blockage than net wrap in damp conditions, and represents a lower running cost per bale. For UK farmers processing smaller volumes of hay, straw, or first-cut grass silage, this bundling method provides dependable results without the complexity of net wrap systems.
🚘
Compact Footprint, Easy Transport
Overall dimensions of 1300 x 1300 x 1350 mm and a total machine weight of 440 kg mean this round baler moves easily between fields, through tight gateways, and over rural road networks. No specialist haulage is needed — the standard tractor and trailer combination covers everything farmers in the UK need for routine seasonal operations.
⚙
Wide Picking Width for Field Efficiency
An 800 mm picking width means the machine sweeps a broad windrow in a single pass, reducing the number of passes per field and cutting total fuel consumption per tonne of baled material. In UK conditions — where weather windows for baling can be frustratingly short — that field efficiency genuinely matters to the bottom line.
How the 9YK-870 Round Baler Works: Principle & Materials
The baler is hitched to a tractor via a standard trailed drawbar connection and driven by a 540 rpm PTO shaft. As the tractor moves forward at a working speed of between 2 and 5 km/h, the spring-tooth pick-up head rotates at ground level, lifting crop material from the windrow and feeding it directly into the compression zone. Because the spring teeth are mounted on a rotating drum and push the material straight through to the chamber without an intermediate auger or conveyor belt, blockages are rare and the feeding action is smooth and self-clearing in most conditions.
Inside the roll drum compression chamber, the crop material builds against a rotating drum array that applies progressive pressure as the bale grows outward from the centre. This roll drum design — as opposed to a belt-type chamber — handles coarser, stemmy materials like straw and reed canary grass particularly well, maintaining consistent pressure even when the crop flow is uneven. The compression room is 700 mm wide and achieves a final bale diameter of 630 mm.
When the bale reaches its target size, the operator initiates rope wrapping. Wrapping twine is threaded through the machine and automatically applied around the circumference of the bale to hold it intact on ejection. The rear gate opens, the bale rolls out onto the field, and the gate closes ready for the next cycle. The entire eject-and-restart sequence is designed to be completed without the operator leaving the cab on level ground, keeping cycle times short and field throughput high.
Structurally, the frame and chamber components are fabricated from high-tensile structural steel with a corrosion-resistant primer and topcoat applied at the factory. The pick-up teeth are heat-treated spring steel, designed to flex over stones or ground undulation without snapping. Rubber-mounted bearings and hardened steel drive shafts within the gearbox assembly are sized to handle the lateral shock loads typical of field conditions across the UK’s varied soil types, from heavy Midlands clay to lighter chalk downland.

Factory, Quality Control & Custom Configuration
The 9YK-870 round baler is manufactured in a dedicated agricultural machinery facility with a production line covering fabrication, welding, heat treatment, painting, and final assembly under one roof. Every baler passes through a pre-shipment functional check that verifies PTO engagement, pick-up rotation, bale chamber clearances, and rope guide alignment before it leaves the factory floor. Welded joints are inspected visually and tested under load; painted surfaces receive a two-coat system for corrosion protection, critical for the damp conditions typical of UK farm storage environments.
One area where we stand apart from standard catalogue suppliers is our custom configuration capability. UK buyers working with unusual crop types, non-standard tractor PTO arrangements, or specific field access requirements can request modifications at the order stage. These include adapted pick-up width configurations, alternative twine guide setups, modified drawbar heights to match unusual tractor hitchpoints, and bespoke colour schemes for agricultural contractor branding. Minimum order quantities for customised builds are discussed on enquiry — contact the sales team directly to explore what is feasible for your operation.
Customer Success Story
Real results from a UK livestock operation
Case Study — Peak District, Derbyshire, UK
Holden Upland Livestock Farm — Sheep & Beef, 280 Acres
James Holden runs a mixed sheep and beef enterprise on steep Derbyshire hill ground, cutting three fields of meadow hay each July and one cut of ryegrass silage per year. His existing ageing large-format baler required a 75 hp tractor and produced bales too heavy to handle manually in remote fields accessible only by quad bike. After enquiring about a right-sized alternative, James trialled the 9YK-870 round baler behind a 40 hp Kubota — the only tractor he could drive into several of his smaller in-bye fields.
The baler handled the mixed hay windrows without issue, producing firm, well-shaped bales at around 4 km/h working speed. The lighter 630 x 700 mm bale size proved easy to manoeuvre manually and loaded neatly onto a quad trailer for collection. James estimated a fuel saving of roughly 35% compared to operating his larger baler, alongside a reduction in soil compaction on his wetter permanent pasture fields.
“It’s done everything I needed it to do. Straightforward machine, no fuss — just what you want at harvest time.”
— James Holden, Holden Farm, Derbyshire, UK
★★★★★
“We run this on a 35 hp Massey and it keeps up with three cuts a year without any issues. The spring teeth clear themselves even in heavy second-cut grass. Very happy with the build quality.”
— T. Murray, Dairy Farm, Shropshire
★★★★★
“Ordered it for straw baling after barley harvest. The rope wrapping is simple to set up and the bales come out tight every time. Size is perfect for our storage barn. Would buy again.”
— R. Stafford, Arable Contractor, Lincolnshire
★★★★★
“Compact, lightweight, and genuinely easy to maintain. I use it across four client farms in the Welsh Borders and the machine handles the hillier fields without trouble. Great value for what you get.”
