The lower ends of the cylindrical shaft casings 30 are formed so that the diameter of the corresponding portions of the cylindrical shaft casings is greater than that of the upper end side; even larger flange parts 30B are formed integrally with the lower ends; and the assembly is connected by bolts to the mower deck 20B. In this embodiment, it is preferred that each of the first and second blades be disposed so that a rotational trajectory of the first blade and a rotational trajectory of the second blade overlap each other, and respective rotational phases be mutually different. 2007 KUBOTA F3680. Therefore, the strength of the blade shaft support structure and the mower deck must be kept very high because the provision of a large distance between the mower deck and the power transmission pulley results in a situation in which a strong tension operates on the power transmission pulley in a position set at a distance from the mower deck, and there is a possibility that a bending moment will forcefully operate on the blade shaft. Discharging clippings behind the deck, under the mower, dramatically reduces the noise level of the deck for both the operator and for bystanders. Z231KW-42. (PITTSBURGH, PA, US), Click for automatic bibliography 21HP. Steering: Hydrostatic power assisted. Rear-discharge decks also reduce the potential for debris or foreign objects to be discharged at dangerous velocity, making them a popular option with municipalities as well as parks and recreation departments. KUBOTA F3690 REAR DISCHARGE MOWER (7699) USED KUBOTA F3690 REAR DISCHARGE MOWER FOR SALE: Kubota 36Hp Diesel Engine (4 Cylinder) 72” Rear Discharge Deck. The UltraCut Rear Discharge deck reduces clipping over-processing using a counter-rotating blade design and patented Flow Control baffles. Now, you simply take the most efficient route and get the job done faster. The flat gears 40 for power transmission are housed in the interior space of the connecting casing 31. 1870 Hours. In addition, there is a drawback when the bevel gear itself has a small diameter in that the noise in the gear meshing portion increases further due to the load that operates in a concentrated fashion on the meshing portion that has a small number of teeth. The right and left blades 21 that are connected and interlocked using the power train 4, which is composed of the flat gears 40 in this manner, are disposed so that the rotating track of each blade partially overlaps the other, but the blades are mutually offset in phase in the manner shown in FIG. VISIT OUR WEBSITE. Kubota. Therefore, a configuration is formed so as to have sufficient strength in order to support the two blade shafts, whereby the mower deck itself can be composed of a thin member that has strength in order to shape the intended blade rotation space. Other embodiments of the present invention will be listed next. Transmission: Hydrostatic. Send him a … A lawn mower is further known in which motive power transmitted from an input shaft is branched at a pair of power transmission shafts to provide input to a gearbox disposed in the upper portion of left and right blade shafts and to transmit shaft power via a bevel gear mechanism or the like as a means to pivotally transmit power to a plurality of blade shafts in adjacent positions (see Japanese Laid-Open Patent Application (JP-A) 2003-158907 (Patent Document 3), for example). The drive is taken from the Power unit via heavy duty V-belts to each rotor. For those looking for additional noise reductions as well as an increased quality of cut for the most highly manicured appearance, Exmark offers its Finish Cut baffle kit for the UltraCut Rear Discharge deck. At that time, the company focused on manufacturing a line of mid-size walk-behind mowers and turf rakes. Can be used as a rear discharge or recycling mower. In FIG. rear discharge mower delivers exceptional performance.
