I spoke too quickly when I said that I couldn't give you something specific, or precise in regards to tips on making it harder for thieves. It's been a while since I've worked with the Law Enforcement Community. There is actually a very simple method to reduce the theft of equipment by more than 90%. It is very simple, highly effective and very cheap to implement. All you have to do is paint your equipment. Let's say, for example, that you would paint your Hustler or Scag ztr a nice, bright pink. Now put yourself in the shoes of a thief. Obviously, he wouldn't be able to list it on Craiglist as is and anyone who would willingly buy a bright pink Hustler would know that he wouldn't be able to use it like that since it would attract too much attention. It would be too easy to identify. So our thief would have to either paint the ztr to hide your lovely pink, or drastically reduce his selling price. Now why would he do that when he can travel to other areas of the country and find a Hustler or Scag in its original color? Which will be an easy sell with less risk and work. Of course, the paint should be oil-based. I would even paint the wheels of the ztr. It will cost less than $20 in paint and it might take you 4-8 hours. But keep in mind that the longer it takes you, the longer it would take someone who steal it to try to hide your lovely pink. IOW, what you are doing is making your equipment not attractive to a thief. It is the same principle with making your house less attractive to burglars and sending them elsewhere. You do not need to paint it pink. You could use 1" tape and make stripes instead. And you could use any color you wish. But the point of the exercise is making your equipment standout, be easily recognizable from more than 100' away. You want to discourage someone from being interested in stealing it. With large equipment like ztr, I would say that it should reduce the probability of theft by more than 90%. With smaller equipment like trimmer and blower, it will still work, but I would estimate the reduction of probability of theft to something like 60%. Because of the smaller size, it is somewhat easier to try to hide the paint job you did. Nevertheless, it is a MUCH less attractive piece of equipment to steal. If your equipment is still under warranty, you should verify with your dealer that painting it will have no impact on the warranty. And finally, I would consider painting your equipment as one layer of protection. Additional layers of protection should take you close to 99% theft protected.
