Avant bracket (fast coupler). Hydraulic quick coupler. Probably 200 gallons [270 L] of mixed wood - the label plate is worn off. Can directly shovel up the sand and tip, ready for mixing. Snail at the bottom squeezes the finished concrete out. Equestrians are unplugged to the side. Visible wear on the rubber cuffs on the mixers. Works according to the seller as it should. Been in use this year.
