Balense is the key , looking at what you need and what you can do . central texas gets 35 inches of rain , whare as east texas gets 55 inches a year , more rain more grass . we are also setting up to grow more food then we need to sell it , most would do this with a tractor,,,, this is a trap ,, how meny carrits would you have to sell to pay off a tractor ? costing $5,000 to $20,000 and the calfs we got at the dairy farm for $70 for both holstens will take a lot less carrits to sale to pay off . with the cost of fertilizer going up , its nice to have the manure we get too . The oxen can also , pull fire wood and timber for building out of the forest for us , as well as move chicken tractors , wagons , plow and cut hay . Oxen are not for every one but long ago , oxen where what every one was useing and it worked for them for thousands of years ,,,,,,,
