Drive shaft bearing structure assemblies and methods for a snowblower can include a transmission and at least one drive shaft coupled to the transmission. The assembly can further include a transmission casing containing the transmission. The transmission casing can include at least one bearing structure. The bearing structure can be configured to receive a portion of the drive shaft during axial rotation of the shaft. In some aspects, there can be two drive shafts. In this aspect, the bearing structure can be configured to receive a first portion of each of the two drive shafts during axial rotation of the drive shafts. In another aspect, the bearing structure is bolted onto the transmission casing as a journal bearing.

The drive shaft bearing structure assembly of claim 1, wherein the at least one drive shaft comprises two drive shafts, wherein the at least one bearing structure is configured to receive a first portion of each of the two drive shafts during axial rotation of the two drive shafts. 3. The drive shaft bearing structure assembly of claim 2, further comprising a pair of front track sprockets, each front track sprocket being positioned at a second portion of each of the two drive shafts. 4. The drive shaft bearing structure assembly of claim 3, further comprising a pair of rollers coupled to the front track sprockets, wherein the assembly drives the front track sprockets. 5. The drive shaft bearing structure assembly of claim 2, wherein the at least one bearing structure is configured as two bushings, the two bushings each comprising a bearing surface, and wherein the first drive shaft is configured to bear against the first bearing surface and the second drive shaft is configured to bear against the second bearing surface during axial rotation of the two drive shafts. 6. The drive shaft bearing structure assembly of claim 5, wherein the two bushings of the at least one bearing structure are configured such that the two bearing surfaces are disposed on opposing, opposite sides of the transmission casing, and a center of each bearing surface is co-axially aligned with a center of the other bearing surface. 7. The drive shaft bearing structure assembly of claim 1, wherein the at least one bearing structure is bolted onto an exterior of the transmission casing as a journal bearing. 8. A track-type snowblower comprising: a transmission;at least one drive shaft coupled to the transmission;a transmission casing containing the transmission;at least one bearing structure disposed on the transmission casing and configured as at least one bushing comprising a bearing surface;a main output shaft with a first end and a second end, the first end being separated from the second end by a middle portion, wherein both the first end and the second end are external from, and on opposite sides of the transmission casing, wherein the main output shaft is coupled to both a transmission contained in the transmission casing and the at least one drive shaft and wherein the main output shaft is configured to receive torque from the transmission and transmit rotational energy to the at least one drive shaft; andat least one rear chain sprocket mounted to the main output shaft and at least one front chain sprocket mounted to the at least one drive shaft, wherein at least one drive chain connects the at least one rear chain sprocket to the at least one front chain sprocket;wherein the at least one drive shaft is configured to bear against the bearing surface of the at least one bushing during axial rotation of the at least one drive shaft. 9. The track-type snowblower of claim 8, wherein the at least one drive shaft comprises two drive shafts, wherein the at least one bearing structure is configured to receive a first portion of each of the two drive shafts during axial rotation of the two drive shafts. 10. The track-type snowblower of claim 9, further comprising a pair of front track sprockets, each front track sprocket being positioned at a second portion of each of the two drive shafts. 11. The track-type snowblower of claim 10, further comprising a pair of rollers coupled to the front track sprockets, wherein the transmission drives the front track sprockets. 12. The track-type snowblower of claim 9, wherein the at least one bearing structure is configured as two bushings, the two bushings each comprising a bearing surface, and wherein the first drive shaft is configured to bear against the first bearing surface and the second drive shaft is configured to bear against the second bearing surface during axial rotation of the two drive shafts. 13. The track-type snowblower of claim 12, wherein the two bushings of the at least one bearing structure are configured such that the two bearing surfaces are disposed on opposing, opposite sides of the transmission casing, and a center of each bearing surface is co-axially aligned with a center of the other bearing surface. 14. The track-type snowblower of claim 8, wherein the at least one bearing structure is bolted onto an exterior of the transmission casing as a journal bearing. 15. A method of driving a track-type snowblower, the method comprising: coupling at least one main output shaft to a transmission, which is contained in a transmission casing, and to at least one drive shaft, wherein the transmission casing comprises at least one bearing structure disposed on the transmission casing, the at least one bearing structure being configured as at least one bushing comprising a bearing surface;mounting at least one rear chain sprocket to the main output shaft;mounting at least one front chain sprocket to a first portion of the at least one drive shaft;connecting, using at least one drive chain, the at least one rear chain sprocket to the at least one front chain sprocket;actuating the transmission to rotate the at least one main output shaft;bearing, by the at least one drive shaft, against the bearing surface of the at least one bushing during axial rotation of the at least one drive shaft; andtransmitting torque received from the transmission to the at least one drive shaft through the main output shaft and the at least one chain, wherein at least a first end and a second end of the main output shaft are external from, and on opposite sides of, the transmission casing. 16. The method of claim 15, comprising bolting the at least one bearing structure onto an exterior of the transmission casing as a journal bearing. 17.
