Found this the other day and thought it was worth sharing.
Don't know if any of you are operating up in this area or have maybe seen this machine, but Ainsworth Lumber out of Grande Prairie, Alberta has been running a John Deere 800C as a log loader for the past eleven years and it still looks like it's going strong.
The piece has a lot of neat features on it; undercarriage was stretched to be 20ft by 20ft, has double AC & heating units/ pressurized cab, I think the reach is right around 50ft, grapple is a four cord capacity and pieces are about 16ft long generally - lots more, can read about it in the linked article.

Retail price at the time was $1.5 million for the 800 chassis and I think a 600 chassis option was available; the mill claims it's the biggest log loader in operation to date... not sure if that's true or not, but an 800 is a might big machine.
I actually contacted the author of the article to see if he had any other pictures, but they were shot using film and he threw them out a number of years ago :bash I've done my best to cut a few from the YouTube video, but the smaller ones are originals from when the machine was new. The video is worth watching too!
