Chisel plows have closer spacing and work shallower, sub soilers have wider shank spacing and work at a deeper depth.In my opinion a subsoiler is meant to break up compaction down 15" or deeper.
Chisel Plows – Primary tillage often as a combination tool Chisel points – spike, straight, twisted shovels, and sweeps in a variety of widths; points do wear out and need to be changed Straight and spike points – narrow points (2” to 3”) used to loosen soil, kill weeds, and remove the plow turns over more soil vs. the subsoiler that is a much narrower chisel tooth requiring less resistance. This causes the finest particles of soil To help identify and understand the effects of a hardpan, let me describe a scenario that played out on a property I manage in west Alabama. We were frustrated to say the least and blamed Mother Nature again for our failure in maintaining the clover. With the amount of time, effort, and money spent replanting and managing the clover fields during this three year battle, I can assure you that since this endeavor I routinely check for soil compaction if a food plot is not performing as expected. I would hate to have to pick the rocks uncovered by a ripperI wondered how long we would take to get around to rock picking This is a ih subsoiler along with a td crawler toolbar setup. On a related note way back when our company had a contact to on the cheap, upgrade 50-miles of old time gravel roads (in some cases not much more than 2-tracks) to wider paved roads (6-incbes of black-base on sand/clay grade and then 1-inch top wear coat asphalt),Cutting new ditches at about a 1/2 mile a day created some MISS DIG and phone line re-location problems. Although it can play a significant role in quality soil management, breaking hardpans by subsoiling is not the end-all solution to food plot problems and managers will always be faced with other limiting factors and extreme weather conditions. I was just about to buy one.
Our as you can see in the pictures has the auto resets. Insert the probe at various locations across the food plot. I use a chisel plow almost all the time and use the subsoiler once a year or every other year to bust any hardpan.
It's how plowing around here evolved away from molboard plowing. Bottom line is trying to maximize profit on my farm (cut expenses and increase yields).666 is right-----subsoilers require lots of power; BUT----------you have to consider the work they are doing.Not all soils need subsoiling or even deep surface tillage------see Loadstar's comment. Deeper means more fuel which means more money. (deep tillage-----in strips)A chisel plow is a flex shank implement that is most likely going to not penetrate the hard pan. Plows can create new fields and prepare the field for seeding. The framework for the machine is done in Atlanta and it is assembled in Bellevue. The second year started off similar to the previous year, with clovers growing well and deer using them heavily. A few areas that inevitably have soil compaction and benefit from subsoiling are logging decks and logging roads. We farm with a 2013 Farmall 105U, 1996 Case IH 3230, 2 1990 7120 Magnums (1 fwa, 1 2wd ) 1, 1981 IH 786, 1,1963 Farmall 460 gas, and 1 1948 Farmall H. Have a 2005 2377 combine with correspondening heads. A good rule of thumb is 10-15 additional horsepower is required per shank on a chisel plow. During the first spring after the initial fall planting, clovers were doing great.
Most plows have 1-5 shanks that are set 9 – 12” apart. its 48 inches tall,made for deep work. Usually operated in the 4---8" depth range with staggered shanks so to till a broadcast width and still leave the surface in an open/rough condition. I ran subsoilers with a friend of my moms in Iowa once. It has a double gang disk in front of lead shanks and main shanks with covering disks on the back. While riding around assessing food plots and making notes on management needs, it hit me like a ton of bricks….every clover field that struggled was one of the original food plots – those that had been plowed and planted for at least 15 years by the old hunting club. If you use a single plow you can pull it with a 40 HP tractor if you have water in the tires.
Thinner shanks are suited for agricultural use.
(deep tillage-----in strips)A chisel plow is a flex shank implement that is most likely going to not penetrate the hard pan.
When converting a logging deck or logging road into a food plot, the first step should be to subsoil the area. If you do not own a subsoiler, many companies rent them. If they don't burry it deep enough its possible.
A chisel plow is made to bury residue and a subsoiler isn't.Depends on the region. As you push the probe into the soil, you will feel pressure as you reach the top of the hardpan.
Under these conditions, food plots are producing forage but do not experience optimal growth, or in some cases fail, essentially cheating the manager (and wildlife) of results for their efforts. over the years, every one of the older food plots “tested positive” for the presence of a hardpan about 6 – 8” below the surface. Also own a 1988 9370 IH Eagle semi tractor to pull hopper bottom.Everything else is a conglomeration of stuff to make the farm go round. ... Nearly anyone doing heavy tillage in North America is doing it with a subsoiler/ripper/chisel plow or whatever your preferred term is. Wrong color but that old 48?? The subsoiler must be pulled by a heavy tractor, for its steel-pointed shank is capable of penetrating the subsoil to a depth of three feet. Works well behind the ole 8N. Ain't that the truth. We farm with a 2013 Farmall 105U, 1996 Case IH 3230, 2 1990 7120 Magnums (1 fwa, 1 2wd ) 1, 1981 IH 786, 1,1963 Farmall 460 gas, and 1 1948 Farmall H. Have a 2005 2377 combine with correspondening heads. Recognizing a hardpan exists is the first step in identifying a soil compaction issue. Keyline plowing is a form of subsoiling.
