Thank you! I will probably try to recruit some help but nice to know it's not days or even all day.
More help will make it go faster, but......if they have no experience doing this.......
Some basic safety rules when chipping -
If you have 3 or 4 people, one person feeds the chipper, the rest drag to the chipper. This prevents you from getting in each others way and greatly reduces injury potential.
Always feed a disk chipper from the right side, feeding butt end first and moving to the right of the feed tray. The angle of the chipper disk will tend to swing branches to the left and can knock you down. Long pieces tend to whip up at the end when being fed and can whack you in the face if you are standing directly behind the chipper.
No cell phones, watches or anything else that the branches can snag and send through chipper. Avoid gloves with big floppy cuffs too, like the cheap gray ones sold at Wally World and virtually every hardware store. Its real easy to get snagged on something with those. I prefer to use heavy woven cotton mason gloves with the grippy latex coating.
Chippers are loud, and there will be pieces of pine flying around. Eye and ear protection is pretty much mandatory.
Keep a small saw at the chipper. Sometimes you'll need to trim things to fit.
Its pine, so its soft and will chip easily. Just watch the pine needles. Don't let the rpms get too low if the chipper doesn't have autofeed. With all those needles the chute can clog up fast if the rpms drop enough.
