Sire: Woepke van Groot Altena and Tyske fan Wildcroft.
Grandsire: Vrolijk-, Zetje fan Wildcroft.

Folkert is an intelligent stallion who is willing to work. Working is easy for him.
He is a good mover, but tends to move too fast when feeling tense. His walk is sufficient and his trot good. His canter is sufficient as well, but could be more tactful. He has ability under saddle and does very well in  harness and as a show horse. He gives both driver and rider a good feeling and is easy to work with.
His progeny are a uniform group of developed horses with a lot of charisma. They are beautiful Friesians with expressive heads. They have good posture with beautiful shoulders and neck with a lot of crest. The loins have a nice length. The horses tend to be a little weak in the back and miss length in the croup. They use the backhand very well and have a beautifully deep black colour. Their walk is spacious and powerful, but in some cases the horses use the hind leg a little bit too actively. The trot is very energetic and the hind leg is used very well. Some horses should create more space with the front leg.
