Garden Tractor Advice?

for your acreage and use, i'd p on the riding mower type and go to a small utility tractor. look at the john deere 2000 series utility tractors. 24-31 hp range. 3 point hitch, loader capability. 4wd optional. you will get tired of hauling manure from the horses by hand, and a loader tractor will be indispensable on a 15 acre farm with timber.
