How often are you guys getting rid of old equipment? We've got some string trimmers and blowers that are over 10 years old. We employ a mechanic and he spends 35-50% of his time working on 2 stroke equipment. One of our supervisors spends much of his time ferrying equipment to crews when their equipment goes down. For what we are spending to keep this equipment running and moving it to where it needs to be I feel like we could justify the expense of rotating the equipment out. I'm thinking 3 years and then get rid of it. What do you guys think? We run Shindaiwa.
