I dont have the property yet nor the tractor. Your guidance is helping me understand how much the property I select will effect the tractor I will need. Which I assumed would be the case but I didnt realize how much it will effect the decision. Like anything, when you are trying to get by with a minimum the variable are important. If you have the resources to buy more than you think you will need then you dont have to worry about all the variable. I'm probably like most guys who are getting into land ownership. The cost of the land and improvements needed to do what you want to do with the land not only determine what tractor you need but also limit you financially. The more needs the land has the more cost you will incur. That also equates to more cost in additional HP and weight.
I intend to pasture cattle spring to fall in 20-40 acres. Perimeter fence it and mowing a portion of it and either renting it out for crops crops or adding pasture as I can afford it. That of course would likely result in haying any extra feed and probably haying new pasture while allowing it to mature before putting cattle on it.
It may be that I need to buy a 60 hp tractor to do the maintenance and to developed the property then trade up as my needs increase. But, if I can figure out if I can get by with a 75HP tractor to make 4x5 or even 5x5 bales, then I think I can swing that single purchase. I don't plan on baking hay as a profession so I'm hopping to get by with the lower HP. Sounds like I might if the property is flat and I'm selective on my hay baler as well. I'm learning not all manufacturers of the same size baler have the same HP needs. I assume the balers with lower HP needs also equate to a looser bale??? Or have some engineered thier balers to have a tight bale while using less HP?
