Want to purchase

Has anybody ever used a Hay bale ventilator on their square hay baler ? The ventilator is mounted on the hay plunger, The ventilator pokes a hole through each pad or slice of hay for air to vent when the moisture is above 12 % . I am looking to purchase a ventilator for a John Deere 336 sq, baler. Thank you. katahdinhairsheep.
