A tractor according includes a running vehicle body, a floor provided on the running vehicle body and serving as a floor surface of an operation part in which a driver is located, a floor bracket configured to support the floor, a fuel tank provided below the floor, and a pedal configured to move the running vehicle body forward or backward and having pivot shafts provided on the floor bracket between the floor and the fuel tank.

A fitting for a lubrication point of a device to be lubricated and a connector for removably connecting to such fitting to provide a lubricant from a lubrication device via the fitting to the device to be lubricated are disclosed. The fitting comprises an integrated circuit for providing an identification code to identify the fitting, and a first electrical contact for establishing an electrical path between the integrated circuit and a processor of the connector when a connection between the fitting and the connector is established. The connector comprises the processor and a second electrical contact for establishing the electrical path. The integrated circuit is adapted for transmitting data, including the identification code, via the first electrical contact to the processor.

A grease tool and method for greasing a dual angular contact bearing where the grease tool is fabricated from a single unitary piece of material. The grease tool comprises a cylindrical hub, a flange supported adjacent only one end of the cylindrical hub, and a grease fitting attached to the grease tool to facilitate a supply of grease thereto. During use, a pair of spaced apart O-rings, accommodated by an exterior surface of the cylindrical hub, form a pair of grease seals with an inwardly facing surface of an inner race of the dual angular contact bearing. A supply passage conveys the supplied grease from the grease fitting to a grease outlet(s) located in an exterior cylindrical surface of the grease tool, between the pair of O-rings, for conveyance of the supplied grease radially to the inner race of the dual angular contact bearing and facilitate repacking thereof.

A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.

A cam follower roller assembly has a shaft insertable into a roller. The shaft has a zerk in communication with the channel wherein lubricant can be added to the assembly. The design of the assembly in one embodiment is such that a larger shoulder to shaft radius stabilizes the shaft and limits the shaft from rocking or elongating within a mounting hole. When utilized in the application of a loading mechanism and carriage assembly for trash collection vehicles, one embodiment of the cam follower roller assembly provides greater life and easier serviceability.

An apparatus comprising a fluid fitting such as a grease nipple, which is attachable to a device that requires lubrication, and a complementary coupler is provided. The fitting includes an insertable section for mating with a complementary receiving portion on the coupler. The fitting includes one or more first entry ports through a side of the insertable section of the fitting, and an exit distal to the insertable section. The feed channel exits of the coupler, mate with the entry ports of the fitting when the insertable section of the fitting is in a delivery position, so that a fluid can be transferred under pressure from a fluid reservoir via the coupler, into the fitting.
