Patent number: 11292148Abstract: A saw disc assembly includes a circular plate having a mounting lug defining a V-shaped lug mounting profile extending between first and second sides of a tooth mount. A cutting tooth includes a shank-less body defining a cutting profile at a cutting face of the body and a mounting profile at a mounting face of the body having a configuration for complementary engagement with the lug mounting profile. The tooth mounting profile has first and second flat surfaces engageable with the lug mounting profile so that when the tooth is mounted to the lug, the flat surfaces positively resist rotation of the tooth with respect to the lug about the fastener, while a radially inner side of the tooth extending between the cutting and mounting faces is spaced from the lug and the cutting device.Type: GrantFiled: September 22, 2015Date of Patent: April 5, 2022Assignee: DEERE & COMPANYInventor: Benjamin DiSabatino

Patent number: 10448583Abstract: A disc saw felling head and a method of assembly for the disc saw felling head including a saw mandrel and bearing arrangement. The saw mandrel and bearing arrangement includes a housing, a mandrel, and first and second preset roller bearing packs. One of the roller bearing packs is a tapered roller double-row preset bearing pack and the other of the roller bearing packs is a cylindrical roller single row preset bearing pack. The housing includes a bore and a first and second shelf, wherein each of the shelves defines a depth of the bearings with respect to the housing to accurately locate the mandrel within the housing. The use of preset bearing packs and a housing having predetermined locations for placement of the present bearing packs provides an assembly which requires fewer adjustments.Type: GrantFiled: October 5, 2015Date of Patent: October 22, 2019Assignee: DEERE & COMPANYInventor: Benjamin DiSabatino

Patent number: 9649704Abstract: A saw assembly and saw blade housing are disclosed. The housing includes a pocket portion configured to expose a portion of the saw blade for cutting of material. The housing includes an enclosure portion configured to enclose a portion of the saw blade that is not exposed by the pocket portion. The housing includes an entrance region through which the saw teeth pass during operation of the saw blade in order to enter the enclosure portion from the pocket portion. The housing includes an exhaust vent located within the enclosure portion of the housing and downstream of the entrance region, from the perspective of the operational rotation of the saw blade. The exhaust vent is configured to redirect debris material entering the enclosure portion of the housing via the entrance region, the debris material being redirected in a forward direction from the perspective of a cutting operation utilizing the saw blade.Type: GrantFiled: October 18, 2013Date of Patent: May 16, 2017Assignee: Deere & CompanyInventors: Benjamin DiSabatino, Michael F.
