We were going to do a separate pumpkin patch this year and I was going to put black plastic around the plants and then space the rows to still get the tractor and tiller between. We'll see, I sure have enough room so overall garden size is no problem. If I go with the offset tiller, I guess one side of the row will still always have a tire track in it, but then again, we're just talking dirt here! I just think the 4 footer would be better, not quite as cumbersome? as a 5 footer. We also have a small cultivator and a 5hp rear tine walk behind tiller to get into the tight spots.
