what equipment would you use to build a motocross track and what attachments

bulldozer, front end loader, tractor with a blade and a truck if you need to cart dirt in

All good . Also, a water truck to help keep it packed down.

dozer, bobcat(skid steer), water truck, tractor with a box blade & maybe a finish blade preferebly with a front end loader too. the dozer helps set stuff up & the front end loader on a tractor & a box blade can get ur slope, the bobcat can move small stuff around, the finish blade helps smooth out berms & stuff, & a water truck to keep everything nice & moist. also if you're building something fairly big some people say to put saw dust in with ur dirt to get it to hold moisture better but I've never tried it.

if you're just building a practice track in ur field u can throw somethen basic together with just a tractor & a boxblade if u want.

l built my track with a bobcat and some water thats all you really need
