Speak for yourself - you've got a decent chipper!

It's not unheard of for me to run my little Entec all day. But then it's the same as the newer Timberwolf 18/100G. Gravity feed, 18hp petrol engine... Not exactly the most powerful or productive machine out there.
You'd have to do some serious felling and have a big place to dump your chip if you were to run your machine all day. 6m3 in 45 minutes! That's some serious turnover... 60m3 per day if dumping on site!
