I ordered the locks already, the rack didnt come with them. I needed 1/2 hitch lock pins and the local stores had 3/8. The rack pretty much acted as a display. I had random equipment in the back of the truck for 2 years and never had anything stolen. A matter of fact they didnt take the Husqaurvana or Redmax trimmer that were next to the stihl.
Either way if your driving by a trimmer rack you would assume it was locked. The only people that would notice it wasnt would be someone walking by it or scoping it out. This makes me suspect some random person less.
The pawn shops said that model is the most popular trimmer they see and they would look out for it but if it was stolen by another landscaper it will never show up. I was hoping someone did try this as I could get them for the theft and vandalism. Other then that I'm going to go out patrolling my area like its my gang turf.
