Presently, you could say I work part- time (as an owner, I'm trying to work less than 50 hours a week) and take a lot of family- first choices.
I could easily advertise Or just quit turning away work if someone could handle climbing these trees independently.
I can't imagine wanting to sell my chipper, it's a variable power set-up that can run from about 20 hp to 125-150 HP with a Heavy duty everything that I can move with my mini , feed with my mini, let sit for weeks when not needed, etc.
My regular employee told me she likes mine way better than the 7" chipper we rented for an emergency oak job when my chipper got some moisture under the distributor cap.
If I took a huge horsepower cut and ability to machine feed without damage to the tray , I could get a 90xp.
Currently, happily booked, debt-free, trying to decide what kind of machine to buy.
Besides my chip truck, I have another dump truck and car trailer available with a free driver, a kboom with grapple and 16' bed for hire at jobsites and a grapple/ debris truck to haul brush from brush trailer pruning jobs that gets stored at my property (lots of capacity). Sometimes, my neighbor unloads brush with his log loader grapple from a flatbed trailer or just picks up the whole trailer with a chain, then pushing it into his huge burn pile.
BTW, if I'm hiring a climber, hopefully they can start busy doing climber- skill set work, not chipping. That is what groundies and a mini are suited to do.
By the time the climber is packed up and gear maintained after climbing, there isn't much of any brush left.
