40 acres is 1320 ft x1320 ft or 1.4 mile across my sweep is about 4 ft wide and if i go one row of 1320 ft a day it will take me 330 days to complet 40 acres that s11 months now most of that time crops are in the feild , and then lets hope it does not rain and lets hope its not to hot , and lets hope in the breef amount of time i have my scedual opens up , and this cant be during hunting season, how long would it take to cover 40 acres? and what if you have lots of targets to dig and dont get thru one row a day , my point I think thear is lots of farm feild hunting left lots .
