Well a bob cat .... and that good clean dirt will be fine ....... build away .
ride the track as your building it to see if the angles are all good , then let it dry up for a few days before you ride it so it doesn't rut as quick .
main thing is a good machine to do it and it will be a peice of piss.
Yer im usin a kanga cause i couldnt get a bobcat but it will just take a bit longer
So what once ive tested it and mad it just water it for a few days and let it harden up?? I heard somewere to leave it to set for a few months??
when i built bmx trails i used heaps of water and just made them damp and done it every afternoon for a couple days and they were hard in like 5 days, a month or 2 is a bit long?
After a while once it all packs in everything will shrink too , from weather rain etc, on all the tracks ,jumps we have at our farm they get hammered from the friggin sheep they love em so annoying
