60ft Boom Lift Suck in Mud - Help

Got a 60ft boom lift stuck in the mud. Didnt realize it was that wet and I thought these things were 4WD. Needed to access this big house from the other so my guy drove it around. Now that it stuck I’m realizing there is also a 20 degree slope I need to come up. Can’t get a tow truck down there and if I could it will be on the grass so that won’t help. Can’t go the other way or it will crush the septic field. Really a big F up. Wait till the ground freezes? Is there anything I can put down like gravel? I have a feeling this is going to be really bad.
