I have to agree a lock and chain to a determined thief is nothing,
Remember, most all thief's want things as quite as possible while, them scum
steal your property.
Also remember tractors are valuable and very easy to sell, so the thief will do his homework in certain areas he chooses. They read the for sale section and target those tractors, and scout out the area. They usually strike between the early morning hours between 2am and 3am, these times are when most people are in deep sleep.
The thief's will always try to move the tractor with out starting it, to get it as far from the residence as possible where they load it in a closed van ect.
These thief's work as teams for the most part, and are very good at their trade. Believe it or not once they enter your property they will have your tractor moved and loaded in less then 10 minutes or less, usually less.
Remember, if you are selling a tractor, by all means be on your toes, this is when you are most vulnerable. Also the guy who looked at your tractor that morning could be the same guy stealing your tractor that night.
The best deterrent we have found is a free roaming dog who barks, thief's
hate dogs and will usually pass when one is on the job.
The main point is to use common sense, the more difficult you make it for the thief,the more likely he will pass .
This Information I have given, comes from many years of experience dealing with scum bag thief's, I am retired law enforcement and have heard from the mouths of these thief's the things I told you.
Besides the DOG I recommend the front tire be removed if you are not going to be home for an extended time . The hidden kill switch will thwart amateurs
but as I pointed out not a well set up ring working a area .
If you don't have a barn or shed, keep your tractor where you can see it from
the house, preferably under or near a pole light in the open , thief's don't like stealing in the open. If you have a set up where the tractor can be blocked in
by another vehicle all the better.
Again these tips come straight from the mouths if the thief's who are part of a well run ring.
