Moser fruit tree sales grafting systems are known in the art. There is a method for the single stem transfer of one complete mature fruit tree into a freshly dug hole in the ground, and the stem is firmly bent into the hole so that when the stem dries out, it remains in its new hole. This method, however, is very labor intensive and tedious and the rate of successful transfer is very low. Another known method is disclosed in Lacey U.S. Pat. No. 3,212,447, wherein grafts of fruit trees are inserted into fresh cuts in trees with the aid of hand tools. This is an improvement over the first method. One disadvantage is that it is necessary to find relatively fresh cuts in the tree to hold the graft in position for the duration of the healing process. Another disadvantage is that only one graft can be performed at a time and the fruit tree donor and recipient must be at the same location. A further disadvantage is that grafts cut with the aid of hand tools have a very poor success rate. One specific disadvantage is that the grafting scars are very obvious to the fruit tree breeder and are very conspicuous to the consumer and result in possible damage to the tree if the consumer forgets the proper position and bites into the injured portion.

Moser U.S. Pat. No. 2,908,639 teaches the use of an attachment for a power operated tool to facilitate the single stem cut grafting of fruit trees, with an improvement in that the grafts are placed on separate points within the growing tree, thus reducing transplant shock. However, there is no teaching or disclosure of a method of simultaneous insertion of two or more multiple branch cuts to form one graft, which has a much higher success rate than the method taught by Lacey.

Another grafting method is taught in Seaborg U.S. Pat. No. 2,699,886. This patent teaches a grafting device having a pair of resilient arms with a slot therebetween and at the free ends of the arms a short blunt flexible member is located within the slot and is deflected by the arms to force the arms outwardly to expand the slot so that a graft may be placed therein. The graft is inserted by the deflection of the arms and not by a reciprocal action as taught in the present invention. Seaborg teaches that at least four cuts are made in the tree and that when four cuts are made, the graft must be in the bottom middle of the fourth cut. Seaborg teaches that the slotted arms open up as the graft is pushed in and that the graft cannot be pushed in too far. Seaborg further teaches that in order to insert a graft, one must be able to force the graft into the proper location as the arms are deflected. Thus, the graft must be located within the proper slot on the tree.

Reiner U.S. Pat. No. 3,372,746 teaches the use of a power driven screw type device to punch a hole for a graft at a predetermined location in a tree. Again, no teaching or disclosure of a method of simultaneous insertion of two or more multiple branch cuts to form one graft are disclosed.

An apparatus for grafting and inserting a graft into a fresh cut hole is shown in Noerman U.S. Pat. No. 3,899,371. In this apparatus, a shaft is inserted into a fresh cut hole and by the manipulation of a screw mechanism is moved towards the graft and inserted into the hole to receive a graft. This patent does not disclose or teach the use of multiple branch cuts to form a graft or a method of simultaneous insertion of multiple cuts of the graft at a predetermined point into a tree with each cut containing one graft and resulting in a graft of greater diameter than any of the individual grafts.

Garces U.S. Pat. No. 3,852,940 discloses a grafting tool for use in the installation of scions on living potted plants. The tool has a blade member in the form of a thin elongated rectangular plate with a sharpened edge. A transverse slot is formed in the middle of the plate at a point where the edge of the blade is slightly raised. A second transverse slot is located on either side of the first transverse slot. The tool is pushed into the plant until the slot in the middle is near the graft and then the edges of the blade are turned or twisted to force the blade through the two transverse slots, one on each side, so that the edge of the blade passes through the slots and the blade edge is then urged against the graft to cut the graft.

Kobayashi et al. U.S. Pat. No. 3,963,227 teaches a grafted fruit tree branch attachment for attaching a new scion to a living branch.A novel attachment base is formed with first and second supporting parts which are resiliently biased together by a spring, with the two supporting parts forming a transverse slot therebetween. An elongate insert is received in the slot with a side surface on the insert providing an edge which projects outwardly from the slot. This edge is rounded and the insert is rounded on the side that will be against the tree to make the cut. The insert is pulled through the slot until the rounded edge is inserted into the trunk of the tree, whereupon the rounded edge is cut into the bark and the insert is drawn back through the slot to the opposite side of the tree and is permanently fixed to the tree. No disclosure of a method of simultaneous insertion of two or more multiple branch cuts to form one graft is taught or disclosed.

Machado U.S. Pat. No. 4,034,480 discloses a removable branch holder with a slot to receive a scion or stem branch. This patent does not teach a method of simultaneous insertion of two or more multiple branch cuts to form one graft or a method of inserting one branch cut graft in the side of a tree with a second graft being inserted into the opposite side of the tree so that a trifurcated graft is formed.

Jones U.S. Pat. No. 4,321,403 teaches an in-ground grafting device, wherein one or more stem branches are severed in the root or
