Swampcat07 and BioWare', Thank You
Both are really good ideas, one of the guys I work with had 2 ATVs stolen off him in years past.
The last one was stolen after the thieves took a truck and ripped the doors along with door framing off his barn.
He said he took a post hole digger and dug a hole about 30'" deep, fastened a length of chain to a screw in mobile home storm anchor and screwed it partially in bottom of hole and filled hole with concrete. Now he just wraps the chain around his frame or axle and locks it up, nobody has stolen another one since.
And I think if you would put a piece of 4"pipe of the right length with a hole cut in it to access the lock on the chain it would take some time to get to chain or lock loose to steal it.
I bought a Bulldog Alarm that detects shock or current drain, have not installed it yet. I think I'm going to go with the buried anchor chain and alarm, and as soon as I can get one of those pay as you go phones and attach to ATV, great idea, the cheapest theft GPS plan I found was around $250 a year.
