brush hogs under 5' are hard to find used.
Not sure on prices of 42", i've been shopping for a 48" and the least expensive new i've found is rural king, $860.
Land Pride is $1200 and something.
I just got a quote a new titan, cash and carry (no setup or delivery) for $850. Probably what I'm gonna do.
Used ones run what, $500,600 in decent shape and you're taking a gamble to some degree. $200ish for a gear box if needed, maybe blades and $100 for a shaft if it's not inlcuded...
Did find a guy with a landpride 48 in NY state, asking $700. But it's a 6-7 hour round trip for me...vs 45 minutes and a warranty..
just to help ya out..
you want a 48".... & guys put them on there all the time..
but pretty sure that tractor is rated for a 42".. (like my B7200 was)
& thats real easy to come by. titan makes one in that size for the KUBO & it even comes in orange.
pretty sure it was $599 new when i bought it for mine.
