I'm trying to decide between purchasing a Great Dane Chariot , 60" deck, 25hp Koehler w/ 600hrs on it or an ExMark Turf Ranger, 60" deck 22hp Koehler w/ 800 hrs. Both are in very good shape and are great deals. I've got about 3 acres residential law to mow (may consider doing extra lawns on the side) , half is a bumpy field (moles) and the other half of the lawn has a lot of pine trees to go around. Anybody worked with either of these mowers? What do you think about them? Would one work better than the other? Thanks!
