Helpful hints:
-Watch your CG. Make SURE you have at least 200lbs on the hitch ball, otherwise the trailer can start whipsawing and toss your tractor in seconds before you can stop.
-Many people like to use the bucket to prevent the machine from moving forward on the trailer. If the bucket is forward, put it firm against the front of the trailer. If the machine is on backwards, drop the bucket lip over the back of the trailer, if there is room to do so.
I ran my chain around the hitch ball on the rear. You can also wrap it around the rear axle of the machine. In the front, you can either use the brush guard or run the strap through the loader cross-over tube. My dealer made big points with me by running a chain through this tube and chipping my paint. A strap would be a better idea or use cardboard on the corners to protect the paint when you cinch down the chain or strap.
When strapping, remember to tension the chains/straps as far away from one another as possible. If you chain right below the attach point, the machine will move. If you fix the rear strap six feet behind the machine and the front strap 6 feet in front, there is much less likelihood that the machine will move. Use heavy 8-10,000 lb strapping (Home Depot $13!!!) . I have seen machines tied with motorcycle straps and this is absolutely unsafe.
If you only have one chain, use the chain on the rear of the trailer and then cinch the chain tight with the front strap. If you are involved in an accident, the chain will take a lot more than even a 10,000 lb strap in stopping forces.
Double check your tire pressures, both on the trailer AND on the machine -even for a short haul. Low pressure tires on the machine make it "squishy" on the trailer under way and low pressure trailer tires will overheat quickly under load. And, unless you haul on that specific trailer with that specific machine on a regular basis, verify the stability of the load every 10 mph, starting at 20mph. And, when you first get rolling, make absolutely sure the trailer brakes are functioning by trying a firm stop at a low speed. Then go up to 30. Wiggle the steering wheel to upset the trailer slightly. If all settles back to normal, go to 40mph and repeat. Keep it under 60mph unless you are pulling with a semi-tractor trailer (heavy) class vehicle. The combined weight of the machine and trailer is considerable.
Hope that helps...
