It uses a 21 cc motor and the KX080 machine uses a 28 cc motor and the KX080 is more efficient and really about as small(flow wise) I would recomend for this type of head. The KX080 makes about 26gpm. This is a mulching head not a flail mower so it is completly different and I would guess performs different than a Flail mower. Not saying it is better just clarifying that I have no experience with flail type mowers n my Mini ex. So The TB260 I am hoping to buy is rated at 27 gpm and I was given the actual flow of the machine at 3000 psi and it makes about 27 hp at the boom. So in theory it will give me about 42% more power over the Kubota KX161which is a dramatic increase.
horsepower = (psi * gpm) / 1714 so none of your math works out. 19 gpm @ 1000 psi = 11 HP and 27 gpm @ 3000 = 47 HP. Someone is lying to you.
