Go for the 3720, you will not regret the extra size.I am looking at buying around 70-90 acres here in Iowa. Haven't talked to the dealer yet, but have done a lot of reading.
The acreage consist of around 20 acres of timber. Will be building an 20-25 acres lake with the driveway being around 1500 feet from the road.
The ?? is will a 3520 be too little or should I get the 3720? Either one will have a cab on it.
I would rather have a little more power to spare than regret not getting it.
