==Benefits to the New Gearbox Design==
The new box has the following benefits:
<br/>
*The box is totally '''reversible''' in any orientation for the four wheels. 
<br/>
*The same motor sits '''adjacent''' to the drive shaft instead of in-line, making the box only '''20" long''' instead of 30"
**This enables us to '''narrow the wheelbase considerably''' (which is definitely needed in order to fit the tractor safely on any trailer other than a semi). 
<br/>
*Still '''modular''' - you can use it in other applications as well.
**Gives the option for '''expansion''' into narrower wheel-based vehicles (Such as the Car or MicroTrac)
<br/>
*Allows for potential gear shifting & '''speedier movement''' if you want to add different size sprockets
<br/>
*'''Stronger''' and shorter 3" drive shaft instead of 2" (Less likely to break)
**This also means that using '''skid steering becomes a viable option''' again
<br/>
*'''Easily serviceable''':
**Both sides are open with '''plenty of lengthwise room''' to slip the motor, sprockets, and bearings out if needed. 
**Hydraulic motor inputs/outputs '''easily accessible'''.
**Clamp is essentially just a large C Clamp with two long bolts.  When removed, '''the whole box comes out'''.
