ROTOR SPEEDS
The EL 131 must only be driven at 1000 rpm PTO speed.
The selector lever (L) (shown in the neutral position on photo 7) associated with invertable gearwheels enables
4 different rotor speeds to be selected (see table 6).
To invert the two gearwheels the machine must be tilted forwards, thus avoiding oil loss.
To do this, proceed as follows :
- Uncouple the PTO shaft.
- Reduce top link length to the minimum.
- Lift the machine to the maximum.
- Remove the gearbox rear cover.
- Invert gearwheels.

SET OF PINIONS
The gearbox is factory fitted with a rear PTO shaft (P) which rotates at the same speed as the tractor PTO shaft
(photo 8). An extra implement can be driven by a secondary PTO shaft which should be assembled and used
according to the legislation in force at the time.
The rear PTO shaft is 1 3/8" 6 spline profile, and must not be used to transmit more than 37 kW (50 hp. It
should not be used with the gears disengaged (neutral) when driving a secondary implement (seed-drill etc.) as
this could damage the gearbox due to a lack of lubrication.
If the rear PTO shaft is not used, always put cover (E) in place (photo 7).
