Product Description

Agricultural Machinery Parts Side Delivery Rake Gearbox

The gearbox is a designed to alter the output speed of your tractors PTO shaft. Its versatile design allows the gearbox to be used as either an increasing ratio or decreasing ratio gearbox to suit your needs.

As a decreasing ratio gearbox it will reduce 1000 rpm PTO shaft speed to 540 rpm allowing the use of equipment designed to operate at 540 rpm.
As an increasing ratio gearbox it will increase 540 rpm PTO shaft speed to 1000 rpm.

The gearbox is assembled with 2 x internal splined sleeves. One 13/8"Z6 the other 13/4"Z20. These splined sleeves allow for direct coupling to your tractor's PTO shaft as the input. The gearbox is also supplied with 2 x separate shafts with matching splines. These are easily assembled to give you the required output shaft.

Role of the Side-Delivery Rake Gearbox

Right-Angle Power Transfer: Typically, the tractor's PTO shaft is horizontal. The rake's rotating parts, such as the basket or toothed wheel arms, usually run on vertical or tilted shafts. The gearbox allows for this 90-degree (or other angle) power transfer to be done efficiently to achieve the specific design and function of the rake.

Speed Reduction/Optimization: The PTO shaft runs at high speeds. The rake's teeth or wheels need to rotate at a specific (usually low) speed to gently and efficiently gather and move hay into a uniform pile without tangling the hay or causing excessive blade loss. The gearbox reduces the input speed to the optimal operating speed.

Torque Transfer: Gathering hay, especially heavy or wet hay, requires ample torque. The gearbox transfers the necessary torque from the tractor to the rake's working parts, ensuring smooth and consistent operation.

Load Management and Protection: The transmission must be able to withstand the varying loads created by constant operation in dusty, sometimes uneven field conditions, and handling different hay densities. The transmission is designed to absorb these stresses, protecting the tines/wheels and the tractor's power take-off (PTO) from damage.

Synchronization (available on some designs): In multi-basket or complex rake designs, the transmission system ensures that all working parts operate in sync, resulting in a uniform, consistent windrow.

Directional Control: The transmission ensures that the rake wheel or tines rotate in the specific direction required, sweeping the hay inward toward the center or to one side to form the windrow.

Side-Feed Rake Transmission Benefits

Gentle Hay Handling: By precisely controlling the speed of the rake tines, the transmission enables the rake to gently sweep through the hay without excessive tearing or breaking up the hay. This minimizes the loss of blades (the most nutritious part of the hay), thereby improving the quality of the forage.

Consistent windrow formation: The consistent, synchronized operation achieved by the transmission ensures that hay is collected into uniform, fluffy windrows. This is critical for subsequent baling or chopping, as it increases efficiency and reduces machine clogging.

Rugged and durable: Hay harvesting requires constant operation in dusty, dirty fields. With a rugged housing (usually cast iron) and high-strength gears and bearings, these transmissions withstand continuous use, vibration, and occasional shocks, ensuring a long, reliable life.

Field reliability: Transmissions are typically sealed to protect their internal components from dust, dirt, moisture, and crop residue, which is critical for consistent performance during the critical hay harvesting season.

Optimize efficiency: By efficiently transmitting power and providing the right speed and torque, the transmission helps improve the overall efficiency of the hay harvesting process, covering more acreage in less time.

Protect the driveline: It acts as a buffer between the tractor power take-off (PTO) and the rake working parts, absorbing stress and shock, thereby extending the life of the implement and tractor drive system.

Side-Feed Rake Gearbox Applications

Wheel Rakes (usually simple direct drive, but some may have small gearboxes for specific functions): While many wheel rakes are ground driven, some advanced or larger models may incorporate small gearboxes.

Rotary Rakes (single or multi-rotor): This is the primary application. The gearbox drives the spindle, which rotates the racks to form the windrow.

Basket Rakes: The gearbox drives a rotating basket that sweeps and lifts the hay.

Windrowers/Windmowers (some types): In machines designed to combine multiple bales into a larger windrow, the gearbox drives a specific conveying or lifting mechanism.

POWER To ensure the correct use of the product we recommand to pay attention to the specifications mentioned on our technical sheet.Consider also the input rotation speed,the power input and the transmission ratios.Where the rotation or other working conditions are different,please contact LongQuan technical department.

LUBRICATION
The reducer is usually supplied without lubricant.The recommended quantity of lubricant is indicated on our catalogue and the first replaced must be done after 50-60 hours of running,then replaced after 600-800 working hours. The emptying of the gearbox should be made immediately after the working,with the oil still hot,in order to avoid the deposition of sludge.Check frequently the oil level and top up the oil whenever necessary.
