the bat tube and is held in the interior bore 58 of the port 52 and will spread the slots 56 as the fastener is seated the screw 60 illustrated will thread into the bore 58 for substantially the full length of the bore the spreading of the post 52 on the interior of the tube will cause a tight locking action as the disclosed screw 60 pulls the saddle surfaces 50 up tight against the outer surfaces of the tube 28 b the opening 66 in bat tube 28 b is countersunk so that the head of the fastener 60 does not protrude from the bat tube to cause snagging of straw or other materials as the reel is operated the length of the hub 46 axially along the tube which is indicated generally by the dimension indicated by double arrows 70 in fig2 can be much greater than that needed for the lower finger portions 45 of the tines which should be tapered and small so that they operate satisfactorily in various types of grain hub length axially can be independent of the axially directed width of the lower portions of the tine and the width indicated at 70 is selected to obtain good stability against sideward loads and reduce the likelihood that the tines or fingers will work loose the mounting of the tine or finger 32 is thus by using a single screw or other fastener such as a threaded bolt rivet expansion plug or other anchor only two parts total that expands into the post the slit on the post on the interior of the bat tube causes expansion of the post on the interior of the tube so that the finger or tine is held tightly in the hole through which.
