Thank fully I don't have those issues any more... my biggest threat with stealing now is internal.
I agree I was lucky to only have lost one blower (which the police recovered). The law of averages mean you'll generally get nabbed.
Absolutely sharpened blades every 10 hours on the mower and changed oil every 100. mower comes off blade comes off and a new one put right back on. and the old blade is added to the pile to be sharpened. and the mower goes back on the trailer. I did not have enough room in the 10x20 garage for three trailers worth of stuff each night...plus any backup or specialty equipment.
The storage lot I used was fenced, had 24 hour security with key card access to the lot.
All a lock does is slow the thief down...
