yep that's the way I've run mine over the years... We got the same stuff... tractor wise and a 5' wide, heavier than h... bushhog.. Easy to do wheelies in the higher gears and a jerk of the throttle with the raised bush hog hung off the back.

You've probably done the same thing I have at times driving over trees big enough that it's uncertain whether the tractor going to make it over them or will it get hung up on top of a bunch of bent over trees.. and you certainly can't back up one you are on top of them...

Ford changed the names more often than the design.. The 841 and the 4000 are of the same design. Mine's the next to the last year ('64)of production of that vintage 4 cylinder design.. a '63... before they went to the 3 cylinder based Canadian Ford design.
