The flow regulator is recommended for excavators which have higher hydraulic flow than what can be utilized by the flail mower hydraulic motor, to simply reduce the flow. The flow regulator allows the operator to easily adjust the oil flow to the flail with a rotary knob, to optimize its operation. Ideally the flail speed on a TLBE model is set to around 2000 rpm, higher speeds could result in damage to the flail rotor or motor seals. Higher rotor speeds may also restrict the operation of the boom or slewing, while mowing.
‘We do recommend checking the flail speed before putting the flail mower to work. This can be done easily and safely with a digital tach.
If you have a newer excavator with a secondary flow with close to the ideal oil flow for the flail mower, or digital oil flow adjustment for the flail mower (from the cab), then the flow regulator is not required.
