Use of PTO tiller for Double Dug / Deep beds?
Hello all! I'd like to make a double dug / deep bed 5' wide by 100' long. I have an IH454 (50HP) and was wondering if there was any way to utilize the tractor to make the job easier or if it simply HAD to be done by hand. I was going to look into renting a 3pt tiller for the tractor but didn't know if it would penetrate deep enough. You want to go about 2' down correct?
The plan (in my head) was to till the bed area as deeply as possible first, then dump 1 foot of aged manure on top, and then make another pass to mix it all in. Will this create a true deep bed or would I be better off calling in some buddies and providing beer? I get half off at the local equipment rental shop (good to know people) so if renting a piece of machinery will make this easier I'd rather do it. Long term goal is to add an additional 5'x100' bed each year for at least 5 years. If buying equipment up front as an investment makes more sense I could do that as well. Any help or advice is appreciated!
