My brother & I spend many hours together hand building these machines that measure 54” tall, 28” long, 26” wide, and weighs around 150 lbs. They are constructed of industrial grade materials, and mild steel that has been primed and painted with an out door oil based paint. A regular 120-volt outlet powers a gear motor that turns a tapered rotor inside a cage that can be adjusted with a hand jack for multiple size pecans. Once the machine is set for the over all average pecan in the batch, it can crack over 100 lbs an hour. The shell out of halves is based upon the freshness of the pecans being cracked. Very little maintenance is required in that once a year the bearings may need some grease. The Auto Feeder feeds the machine consistently, but also aids in the cleaning process by allowing dirt & debris to fall out prior to cracking. Both pieces of equipment can fit into a truck bed and can be used for mobile cracking. The machine sells for $3995 plus tax.
