Agricultural PTO Shaft for Round Balers New Holland BR7050 BR7060 BR7070 BR7080 BR7090
The power of the baler is usually transmitted through the PTO (Power Take off) shaft. PTO shaft is a type of shaft, usually installed on the power output shaft of tractors or agricultural machinery, through which power can be obtained from the power output shaft.
In a baler, the PTO shaft is usually connected to a reducer, which then transmits power to the drive shaft of the baler. The function of the reducer is to convert the high-speed rotation of the power output shaft into the low-speed rotation of the baler, in order to better control the movement of the baler.
In some balers, the PTO shaft can be manually operated to control the transmission of power. In this case, the driver can control the rotation of the PTO shaft through the joystick or button, thereby controlling the movement of the baler.

In other balers, the PTO shaft is usually controlled through an automatic control system. This automatic control system can detect the status and needs of the baler through sensors and controllers, and transmit power as needed. This automatic control system is commonly referred to as the "PTO automatic switching system", which can automatically switch between different power transmission modes to maximize the efficiency and reliability of the baler.

Cutting PTO Shaft for use on Round Baler
Most important : minimum overlap 15 cm , end play minimum 4 cm
Procedure for cutting the PTO shaft to the correct length
If the PTO shaft is too long it might bind when the three point hitch is lifted up.Damage might be caused to the bearing of the rotavator or to the PTO of the tractor. Ifthe PTO shaft is too long it mustbe cut.
Both PTO halves must be shortened by equal amounts.
Step 3. Stop the tractor engine and remove thekeys.
Safety Reminder When Using the PTO Shaft
Keep safety shields securely fastened on equipment. Safe operation of the PTO is not possible without these shields in place. A sudden slip or fall could throw a worker directly onto the unshielded rotation shaft. Also, those who are unfamiliar with the equipment, may not recognize the danger of the power shaft.
Wear snug fitting clothes when working around power shafts. Loose clothing can catch in or be wrapped around the power shaft. Do not step over an operating PTO. A sudden slip or a loose shoe string could cause the worker to become entangled in the PTO shaft. Long hair may also become entangled in a PTO shaft. Hair should be pulled back out of the way.
Most power shafts can be extended. These shafts are usually constructed with a square shaft inserted into a housing or casing. It is important that at least 5 ½ inches of the sliding shaft remain in the housing when the power shaft is connected to the tractor. This reduces the possibility of the shafts separating while the tractor is in motion. If the shaft splits, the portion of the shaft connected to the tractor is free to whirl at high speeds, endangering the worker and tractor. If the shaft does separate, disengage the PTO immediately and stop the tractor. Use extreme caution when operating equipment with a separable PTO shaft. Never hook 540 rpm equipment to a 1000 rpm PTO or vice-versa.
