Patent ID: 7357752

Claim:
A power train assembly driveably engaged with an input source, the power train assembly comprising: a transmission module being driveably connected to the input source and including a transmission mechanism and a drive member driveably connected to the transmission mechanism, said transmission module being substantially enclosed within a casing; a creeper module being substantially enclosed within a housing and said creeper module being driveably engaged with said drive member of said transmission module, said housing of said creeper module being detachably mountable to an external portion of said casing; an output assembly including an output member being in driving engagement with said creeper module; and a control interface being configured to selectively engage the creeper module to transform a first speed of the drive member to a second speed of the output member, wherein detaching the housing from the casing does not require disassembling the transmission module from the casing, wherein said creeper module includes a clutch assembly operative to selectively and alternatively transmit said first speed of said drive member to said second speed of said output member, wherein said first speed and said second speed are substantially the same, and wherein said clutch assembly is operative to disengage said drive member and said output member in a neutral mode, wherein said second speed of the output member is substantially zero.
