Dave's Farm is the farm of Arthur's Grandpa Dave. It was first bought by Dave's grandfather Gustav 150 years ago and has been in the family since. Arthur's mom; Jane Read and her siblings Jessica, Lucy, and Fred grew up on the farm and had to do chores there as kids such as feeding the animals like ducks and chickens. In the episode Grandpa Dave's Old Country Farm, Arthur and D.W. go to stay there on a vacation to which they realize that their grandfather needs help taking care of the farm. At first, Dave doesn't want to accept their help because nobody in the family asked for help taking care of the farm, but soon learns that the farm could use some help and has Arthur, D.W., and his good friend Ed Billings help him build a roof for the chickens'
house. In the end he also hires Ed as a farmhand and asks him what he knows about tractor engines. In the episode Grandpa Dave's Memory Album, when Grandpa Dave reveals that he's been diagnosed with Alzheimer's Disease, he mentions that he got lost on his farm because he couldn't remember where he was and also mentioned that he would be moving closer to his daughter Jane. It is unknown if he sold his farm or gave it to one of his other children to live on and still keep it in the family.
