Tieing Down a CUT Tractor
Just as Bill does, we use a clevis through the drawbar to bind down the rear end. On the front end, if it's equipped with a FEL, we slip a chain through the tube brace that runs side to side in the boom arms, if there is no FEL then we have a die lifting eye (a big cast iron loop with a threaded stem like a bolt, VERY strong) bolted through the front bumper.
We always use chain, they are more durable, and will tell you with just a glance in the rear view if they are slack or not. If the chains are dancing it's time to snug them up, when they're rock steady, so is your equipment.
Nylon binder straps, BTW, are not designed to pull at an angle, especially the kind with the flat hooks. If you put one on an angle and put a lot of tension on it you will overload one side of the stitching which could lead to premature failure, and a reduced ultimate breaking strength.
If you are buying new binders, get the ratcheting style of chain binders, they are only about $10 more than the old 'Bear Trap' style and are far easier to use. They will also solve that old "this link is too tight, that link is too slack" problem with the old ones.
Finally, be sure the chain you buy is Grade 70, Transport Grade chain.
Best of luck.

Tieing Down a CUT Tractor
Since your base tractor only weighs about 1,400 pounds even the smallest Grade 70 chain available, 1/4" will suffice.
It has a safe working load limit of 3,150 pounds, therefore two pieces will be good for 6,300 pounds, even with the FEL and an implement this is more than double what is required.
Actually you are better off with just 2 pieces and not 4. If you use 4 pieces and one goes slack it will want to pull the tractor over sideways.
If you have the parking brake locked, and the FEL and all implements down it shouldn't move much even if one chain comes loose.
As a tip though, if you do use the over-center (bear trap) style chain binder, be sure to tie the binder closed with a piece of heavy twine or light rope, that way they can't spring open from a big bump.
Best of luck.

AV8R, with all due respect, especially now that you are a grajiate of an istitooshun of gooderer learning (kidding, but congrats), I don't know what was beaten or how, but I do know they were wrong by the sounds of it.
Also, for the record, there is NO WHERE ELSE on the web to talk about tractors, heheheheh.
According to the "National Safety Code Standard 10:
Cargo Securement" which is now, a continent wide standard, cargo securement generally (except for things like bulk, etc.) must conform to; "Cargo shall be firmly immobilized or secured on or within a vehicle by structures of adequate strength, blocking, bracing, dunnage or dunnage bags, shoring bars, tiedowns or a combination of these."
It goes on to say;
"Minimum Strength of Securement System
10 (1) In this section, the “aggregate working load limit” is the sum of One-half of the working load limit for each end section of a tiedown that is attached to an anchor point.
(2) The aggregate working load limit of the cargo securement system used to secure an article of
cargo on or within a vehicle shall not be less than 50% of the weight of the article.
(3) The aggregate working load limit of the cargo securement system used to secure a group of
articles of cargo on or within a vehicle shall be not less than 50% of the total weight of the group."
So, nowhere does it say "how many", merely "how strong". In fact the 'one per corner' theory would make all of those permanently mounted nylon web binder systems on tractor trailers illegal since they are singles from one side to the other. In fact, if you look at 10(3) above you will see that it specifically talks about a "group of articles".
In theory, you could put one big chain up and over the center of the tractor and it would be legal.
Best of luck.

The Federal Motor Carrier Safety Administration, which is the American counterpart to Canada's Council of Ministers Responsible for Transportation and Highway Safety (try putting THAT on a business card) issued the following statement that I came across researching this suybject.
"While there are some differences between certain provisions adopted by FMCSA and Canada's National Safety Code Standard 10, the contents of most of the Model Regulations have been adopted, or will be adopted shortly, by almost all jurisdictions in the U.S. and Canada."
So there could be still some differences, however the statement goes on (in painfull detail) to say that they "expect full harmonization of the requirements across North America by the summer of 2005" so it appears the differences will soon be gone.
Best of luck.
