9JYY-4.5 Round Bale Picker and Transporter — 4,500 kg Hydraulic Self-Loading Bale Carrier for Large Farm Operations
The 9JYY-4.5 is a tractor-towed round bale transporter with a 4,500 kg maximum payload, dual-group hydraulic loading and unloading, and a tandem four-wheel 400/60-15.5 tyre configuration that keeps ground pressure manageable across wet or soft fields. It handles bales from 1,000–1,400 mm diameter × 1,000–1,500 mm length — covering the full output range of standard round balers — and operates at transport speeds up to 40 km/h on farm roads. Requiring a tractor of ≥50 kW (≈67 hp) and a hydraulic working pressure of ≥16 MPa, it is matched to the mid-range and large tractors already common on commercial hay, silage, and straw operations.
Moving round bales one at a time with a front-end loader and bale spear is the standard default on most farms — and it is expensive in both time and fuel. A single operator making individual trips to shift 50 bales from a 50-hectare hay field can spend 4–6 hours on bale handling alone. The 9JYY-4.5 replaces that workflow: the hydraulic self-loading arm picks bales directly from the field while the machine moves forward, the deck accumulates multiple bales per load, and the hydraulic tipping and push-off system discharges the full load at the storage site in one controlled action. As a purpose-built round bale chaser, it keeps a single operator clearing fields at a rate that front-loader single-bale handling cannot match.
At 3,240 kg unladen weight and overall working dimensions of 9,400 × 6,750 × 1,750 mm, this is a field-scale agricultural round bale collection and transport system — not a smallholding implement. It is built for farms and contracting operations that move hundreds of bales per day during peak harvest windows, where handling speed directly determines whether the crop stays in weather-safe storage or sits exposed in the field overnight.

Round Bale Hauler Advantages — Why the 9JYY-4.5 Outperforms Single-Bale Handling
4,500 kg Payload in a Single Load
At a typical bale weight of 350–600 kg, the 9JYY-4.5 moves 7–12 standard round bales per trip. That replaces 7–12 individual tractor loader runs — cutting field-to-storage time by 70–80% versus single-bale spear handling.
Dual-Group Hydraulic System — Load & Discharge Without Manual Intervention
Two independent hydraulic circuits handle the loading arm and the tipping/push-off deck separately. Loading and unloading are controlled from the tractor cab — the operator does not leave the seat at any point in the cycle.
Bale Size Range Ø 1,000–1,400 × 1,000–1,500 mm
Covers the output range of virtually all commercial round balers — from compact 4×4 silage bales to large 5×6 hay bales. No bale-size-specific tooling or adjustment is needed when switching between crop types or baler models.
400/60-15.5 Dual-Axle Tyres — Low Ground Pressure
The tandem four-wheel configuration spreads the loaded weight across four contact patches, reducing soil compaction during post-harvest field passes when soil moisture is often still elevated after rain or irrigation.
Road-Legal Transport at Up to 40 km/h
The 2,900 mm transport width fits within standard farm road clearances. At 40 km/h tow speed, a contractor can move between fields or farm sites without needing a low-loader for equipment relocation — saving time and reducing haulage overhead.
≥50 kW Tractor Requirement — Wide Compatibility
The 67 hp minimum power threshold is matched by most 4WD utility tractors used on commercial grain and forage farms. No high-horsepower tractor is required — the same 70–90 hp tractor used for raking and baling can tow the 9JYY-4.5 during the collection phase.
Round Bale Picker and Transporter Applications — Where the 9JYY-4.5 Works
This agricultural round bale collection and transport system is designed for operations where bale volume and field area make single-bale handling impractical:
- Grass Hay and Haylage: First and second cut grass fields on farms producing 500–2,000+ bales per season. The 9JYY-4.5 clears bales from the field in batches, keeping each cutting in storage before the next weather window closes.
- Wheat and Barley Straw Collection: Post-combine straw bales scatter across large cereal fields. A round bale chaser running behind the baler clears rows without interrupting the baling pass — the standard workflow for large arable operations handling straw as a secondary product.
- Wrapped Silage Bale Handling: The hydraulic loading arm handles stretch-film-wrapped silage bales without puncturing the film — a critical requirement since any film breach introduces oxygen and triggers surface spoilage. Bale integrity is maintained from field to storage stack.
- Corn Stover and Crop Residue: Larger corn stover bales at Ø 1,200–1,400 mm fit within the 9JYY-4.5’s compatible bale size range, making it suitable for biomass collection operations and livestock bedding programmes on mixed arable-livestock farms.
- Custom Harvest Contracting: Round bale picker and transporter for large farms running custom harvesting services can clear multiple client fields in a single day. The 40 km/h road transport speed keeps transit time between sites low, and the ≥50 kW power requirement means the machine pairs with tractors the contractor already owns.
- Alfalfa Cutting Programmes: Alfalfa fields producing 4–6 cuts per season generate continuous bale handling demand. The 9JYY-4.5’s wide bale size tolerance means it handles the variable bale diameter that results from changing crop density across cuttings without reconfiguration.
Frequently Asked Questions — 9JYY-4.5 Round Bale Transporter
Equipment That Works Alongside the 9JYY-4.5
The 9JYY-4.5 fits into a complete round bale harvest line. These products pair directly with it:
Round Hay Balers
The 9JYY-4.5 is optimized for bales Ø 1,000–1,400 mm produced by standard fixed and variable chamber round balers. It pairs directly behind any baler output in this size range.
Baler Wrapper Combinations
Wrapped silage bales from integrated baler-wrapper machines can be collected and moved by the 9JYY-4.5 without film damage, completing the silage production chain from field to storage pad.
Hydraulic Motors & Control Valves
Drives the loading arm and deck push-off system at ≥16 MPa. Replacement hydraulic motor units and directional control valves are available as service parts for the dual-group circuit.
Where an auxiliary PTO-driven hydraulic pump is used to supply the 9JYY-4.5’s hydraulic demand independently of the tractor’s main circuit, a matched 540 rpm PTO shaft with overrun clutch is required.
