An extended piston is composed of two blocks: the piston base and the piston head. There are multiple ways to remove the head of the piston while still keeping the base intact and in the extended block state where it doesn't have a head.

Obtaining

Update Suppression

Using update suppressors, certain actions within the game can be suppressed to avoid them from happening, such as block updates. When a block is broken or placed, block updates occur to the neighboring blocks which can cause them to be changed in response to the first block being broken or placed. Suppressing the removal of the pistons head will leave the headless piston, this could then be updated to 22w13oneBlockAtATime then it can be picked up and placed into a llamas and/or donkeys inventory.

Explosives

Another way to remove the head from a piston is with a mechanism in which the piston extends at exactly the same time an explosion occurs. When using TNT, this can be done with 10 repeaters set to four ticks. The power of the explosion must also be manipulated, which can be done using other blocks between the explosion and the piston, such as cobblestone walls. Once the piston is headless, powering it will ensure that it stays headless. Once unpowered, it will retract, gaining its head back.
