کد جایگزین گیربکس بیلر گرد T304A با نسبت EP-1:3

① True Reversible Dual-Mode Operation

Unlike most round baler gearbox equipment that operates in a fixed ratio direction, the EP-T304A delivers both 1:3 speed increase and 3:1 torque multiplication in a single casting — switching between modes simply by changing which shaft receives PTO input. For agricultural service businesses maintaining a mixed fleet of round baler and harvester machines that use different drivetrain architectures, stocking one part number instead of two separate gearbox assemblies significantly reduces parts inventory cost and storage space. This design philosophy represents exactly what is an round baler gearbox built for real-world maintenance economics, not just engineering elegance.

② Six Gear Arrangement Configurations

With six named gear arrangements (5, 6, 25, 26, 27, 28) corresponding to different input shaft directions and rotation senses, the EP-T304A accommodates virtually every combination of tractor PTO shaft orientation and baler driveline layout without requiring the operator to rotate the housing or add angle drives. This range of configurations is particularly relevant in what is the difference between round baler gearbox installations across different machine brands — baler manufacturers historically positioned the PTO input at different angles, and a gearbox that handles all orientations in the same housing reduces the cost of maintaining cross-brand serviceability for dealers in Canada, South Africa, and Australia.

③ 94.5 daNm Maximum Output Torque in Reducing Mode

In Type R reducing mode, the EP-T304A delivers up to 94.5 daNm at the output shaft — 945 Nm in SI units — from an 18.4 kW input at 540 RPM. This torque figure covers the demands of mid-size round baler pick-up and bale-chamber drive mechanisms that need a slow, powerful rotation rather than high-speed belt drive. Operators running tractors as low as 25–30 HP can take full advantage of the 3:1 mode while still achieving a useful output torque level for light to medium baling conditions, which is a relevant consideration in regions like sub-Saharan Africa and Southeast Asia where smaller tractors form the majority of the working fleet.

④ Lightweight 19 kg Compact Housing

At 19 kg, the EP-T304A is among the lighter units in its torque class — a meaningful advantage during mounting, particularly on machines where the gearbox is installed overhead or in a confined driveline bay. The GG25 cast iron housing provides adequate stiffness and damping for the rotational loads involved, while the compact 320 mm × 190 mm envelope fits within the same chassis space as the original Comer code unit. This combination of low weight and dimensional fidelity to the original round baler gearbox parts specification simplifies single-technician replacement work in the field, without the need for lifting equipment or additional personnel.

⑤ 500-Hour Oil Service Interval

The 500-hour oil change interval specified for SAE 80W-90 EP gear oil aligns with a typical season's baling work for most commercial operations. For a contracting business in the UK, Ireland, or the Netherlands processing 4,000–6,000 bales annually, this means a single annual oil service covers the maintenance requirement — no mid-season fluid changes needed. The field-accessible oil level plug and drain plugs allow inspection and replacement without removing the gearbox from the machine, and the 1.1-litre capacity is modest enough that the oil change adds minimal cost to the round baler gearbox replacement service compared to heavy-duty units requiring 3–5 litres. This is a round baler gearbox best practice maintenance specification for professional agricultural use.

Speed-Increasing Drive for Belt-Dominated Bale Chambers

In round balers where the bale chamber runs a high-speed belt circuit requiring rotational speeds above the 540 RPM PTO output, the EP-T304A in Type M (1:3 increasing) mode drives the bale chamber at approximately 1620 RPM output speed. This configuration applies to older Comer-code baler designs common across France, Germany, and Argentina where the chamber architecture was designed around faster belt speeds to achieve compact bale density in dry cereal straw and grass applications. How many HP does it take to pull a round baler in this mode? With a 36.9 kW input rating, tractors from 50 HP upward can run the EP-T304A at full rated power in increasing mode.

High-Torque Reducing Drive for Heavy Crop Processing

Switched to Type R (3:1 reducing) mode, the EP-T304A delivers 94.5 daNm of output torque from a 25 HP / 18.4 kW input — a torque figure that exceeds what many larger gearboxes provide when paired with compact utility tractors. This mode suits applications where slow, powerful rotation is needed at the pick-up or feed rotor: dense alfalfa, high-moisture grass, or tall-stem energy crops in regions like Colombia, South Korea, and the UK where crop density varies widely across the baling window. The reducing configuration is also used in specific wrap-table drives on net-wrap bale systems where low speed and high holding torque are simultaneously required.

Comer Code Fleet Replacement for Multi-Brand Dealers

Agricultural machinery dealers in Australia, Canada, and South Africa servicing farms that run mixed fleets of round balers from different manufacturers face the challenge of sourcing replacement gearboxes that match multiple machine designs. The six available gear arrangements of the EP-T304A reduce the number of individual part numbers a dealer needs to stock to cover the same range of Comer-code applications. This simplification in parts management is what makes the EP-T304A one of the round baler gearbox best options for workshop-centric purchasing decisions, where the total cost of stockholding matters as much as the individual unit specification.

Round Baler and Harvester Integration Across PTO Configurations

The Round Baler Gearbox for Round Baler and Harvester application requires the transmission to handle variable input shaft angles — particularly on self-propelled or pull-type harvesters where the PTO drive path is not perpendicular to the gearbox mounting face. The multiple gear arrangement options of the EP-T304A address this directly, accommodating the rotational direction of the input without changing the housing position. This is the characteristic that makes this unit a genuinely multi-application round baler gearbox equipment choice rather than a single-machine solution, and it is the reason this model appears across diverse harvester configurations in both temperate and tropical agricultural zones.

Round Baler PTO Shaft — Matched to EP-T304A Input

The شفت pto بیلر گرد that connects the tractor output to the EP-T304A Shaft X or Y input is produced in the 1 3/8" (6)(A) spline profile to match the gearbox input specification exactly. Our PTO shaft range for this application includes telescoping tube lengths, overrunning clutch protection compliant with ISO 4254-1, and full guard kits for all shaft lengths. Supplying the gearbox and its input driveshaft as a matched pair removes the risk of cross-brand spline-profile mismatches that can cause spline galling and premature coupling wear in the first season of operation.

Complete Round Baler System Supply

In addition to gearboxes and driveshafts, our facility supplies complete round baler machines with all drivetrain components — including the EP-T304A round baler gearbox — specified and tested as an integrated assembly. Buyers sourcing new baling capacity for their farm or contracting operation can choose a matched machine-and-gearbox combination rather than retrofitting an aftermarket unit to an incompatible host machine. This system-level supply is the practical meaning of one-stop round baler gearbox manufacturers service: not just selling a part, but delivering a working drivetrain assembly backed by engineering knowledge of how all the components interact.
