The last contractor I worked for had a Splendimo rear mower/comditioner as did the one before that, they are a damned good mower but they do have one little downfall to them which won't show itself if you are cutting grass at the ideal time in its growth cycle. The conditioner units have a dislike for tangled and over mature grass crops, they will wrap solid and burn out the slip clutches (I done one last year within 30m despite being in the lowest gear on the 7840), it was for this reason that the previous contractor also kept a JD MoCo in reserve, although it seemed to affect the rear mower more than the front one on his Claas 836 set-up, They are one of the more popular mowers around this area now
