How can i make an all-terrain board for getting around my farm for around $1000, I've seen the ones online but 4-inch wheels just doesn't sound that great for woods and mud. If possible I would like to have a car battery or a couple power it as I have a few of those and a wired throttle as i tend to lose small items all the time, i have hills, muds and a small creek i need to cross.

my 2020-2022 idk what year Polaris 570 sportsman efi ran for like 3 hours without oil thanks to my brother. do i need to buy a new quad or can i fix the current one?
