Most cutting pictures are similar to the one above because they capture a beautiful deep stop at the beginning or middle of the turn.
A lot of herdwork and cutting instruction has to do with how to sit and use your feet before stops and during the middle of the turn.
For example, there’s a lot of discussion about sitting and waiting, etc.
There is another phase of the stop-turn sequence that is also critical to understand and ride correctly. It’s at the end of the turn where the horse completes the turn and then accelerates on the line.
The reason why the end of the turn is important is because this is where the horse:
Continues to read the cow undistracted (very important!)
Accelerates in a collected manner as he begins to move out of the turn and on ‘the line’
‘Stays on the line’ and does not go either towards the cow or does not move away from the cow as he travels across the arena (unless forced to do so)
