Agricultural 540 to 1000rpm PTO speed reducer for attachment to tractors
Notes:
- Although designed for attachment to a tractors PTO shaft this gearbox can be used in other applications on agricultural machinery.
- A lug is supplied fitted to the base of the gearbox housing. This must be securely attached to your tractor by way of a chain or mounting plate to ensure the gearbox does not rotate during operation.
- Gearboxes are shipped without oil. Please fill to the level plug with EP90 gear oil before use.
- This gearbox can be used on tractors with 13/8"Z21 (1000rpm) PTO shafts with the addition of our splined adaptor AL00296 (13/8"Z21 internal - 13/4"Z20 external)
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 tractors 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.
