header board is a the board on the front of the trailer, or the board that is on the tractor behind the cab/sleeper. this is made of metal and is to prevent the load on trailer coming thru the cab in the event an accident or other emergency

You're probably referring to some sort of sleeper cab truck. You might be referring to the ICT sleepers.
It functions the same as any other automotive air conditioning system, albeit a sleeper cab tractor will typically have a second compressor for the air conditioning system in the sleeper.
semi cab
Need to be a little more specific here.... I wouldn't direct you to the same place to purchase a Volvo cab as I would send you to purchase a Peterbilt cab. You need to give an idea of what exactly you're looking for.
Depending on how much weight you put on the trailer(garden tractor) you should be able to haul it.
This varies greatly depending on the type of truck. For example, a sleeper tractor weighs more than a day cab, a refrigerated van trailer weighs significantly more than a flatbed trailer, and so on. I drive a tandem axle day cab Sterling semi (this is a semi tractor with a total of 3 axles and no sleeper), and I pull a 53-foot dry van trailer (this is a box trailer without a refrigeration unit). When I have run it across a scale empty with about 120 gallons of fuel (this will also change weight as fuel weighs about 12 pounds per gallon), the whole truck weighs very close to 29,600 pounds. An empty semi can weigh as much as about 40,000 pounds, leaving room for 40,000 more of cargo before reaching maximum legal weight of 80,000.
day cab is a truck with no sleeper, just a standard cab
Cowtown Sleepers can make a sleeper cab for any truck out there.
