I only have about 3/4 acre of lawn on my 10-acre spread. So I handle landscaping chores with a cheap $1000 Huskee 18hp, 42" riding mower with a 42" Agri-Fab drop spreader ($200) for seed and fertilizer. I like drop spreaders more than the broadcast type because of better accuracy, less waste.
Use the B7510HST/LA302FEL to mow about 7 acres of weeds with a 4-ft KK brush hog (TSC, $675 last June).
