NorTrac Subsoiler - 3-Point Hitch
Heavy well made implement. It does have the shear bolt. Used it not so much for subsoil, but just about surface level to make a narrow drainage trench about 6" wide. Worked very good.

Rockin and Rootin in NH
I bought this subsoiler to break up some ground that had been compacted by two years worth of logging operations. I live here in New Hampshire, a.k.a. “the Granite State” which means lots of rocks! The ground is in a 100 year old orchard. Think roots. The skidders had embedded lumber debris up to 10 feet in length as they drove through axle deep mud in the spring.
My tractor is a Ford 8n which boasts a horsepower of 23.
I was skeptical that this was going to be a successful enterprise, but successful it was! I replaced the 7/16 shear pin* with a soft 3/8 bolt for an additional margin there. I snapped one bolt in short order but then I found if I went really slowly when I snagged an obstruction I could stop before the bolt snapped, raise the subsoiler and then proceed forward.
Bottom Line: The subsoiler far exceeded my expectations!
* If you look in the questions section you will see that the Nortrac “expert” says that there is no shear pin on the subsoiler. There are two bolts which hold the backbone to the hitch. The upper bolt is a larger diameter than the lower bolt. When an obstruction is encountered the backbone pivots on the upper bolt and snaps the lower bolt which is therefore a shear pin. I did have to grind off a little of the backbone’s corner to allow it to rotate completely on the upper bolt.

Does the job
I use this subsoiler to penetrate hard pan clay. If you use a rototiller like I do, the blades actually impact the clay pan area, making it even harder and even more impenetrable for water to seep through. Before planting, I use the subsoiler on each row before I disc hill. During the dry season, I need to irrigate less because the water is naturally "wicked" up from the clay area into the topsoil. It's a better designed product with a sheer pin and was less expensive than the one at the tractor store.
Wish I had this product with the pipe laying attachment when I was putting in the irrigation system.

Pleasure to use and easy to put on the tractor
Bought this subsoiler to plow some rows for wine grapevines I was getting ready to establish. The area was undisturbed pasture grass, so I use a box blade to initially scrape the soil before using the subsoiler. After 5 or 6 passes I was able to get down to 12-14 inches using the subsoiler, using a 32 hp Kubota. I took it slow as the soil was rocky and contained a few roots, and never broke the shear pin or bent anything on the implement, after 600 feet or so of plowing. The soil was mixed clay, and I plowed after a rain for it to be as moist as possible without the tractor sinking in. In the future, I'll probably put a weaker shear pin on just to be safe, as I have broken quite a few when augering holes in this soil. The subsoiler is well built but light enough to put on by hand, unlike most 3 point hitch implements. The resultant trench was okay for bare root vines, though I'll probably buy the mid buster next to do the final passes. All in all, well pleased with a fairly priced product.

Does the job well
Shear pin feature is great. Buy a bunch of case hardened bolts and the store and be ready to swap them out when you hit roots. It's much nicer to break a few dollars in shear pins than a $100 plus attachment. Make sure to adjust 3 point hitch to limit left to right movement as much as you can and make sure attachment is completely vertical when lowered for best penetration. Great price - well worth the money.

A great value
This is one of the few items that I have purchased lately that is well built and does exactly what it is supposed to do.
I roto til my garden each spring and fall. If you have ever used a roto tiller, than you know how hard it can be. If the tiller encounters hard ground it can tine walk and get away from you. In a word, the process can be exhausting.
This year, I broke up the ground with the sub soiler. Once that was complete, I used the roto tiller for a finish pass. What I difference, no tine walking, jerking or other undesirable events. In fact, I was able to control the tiller with one hand.
The sub soiler does not come with any directions but with a bit of mechanical skill and a look at the picture you should be able to mount this on your tractor with no problem.

Nice solid piece of 3 point equipment
When our local supply house had none in stock and wanted over 2 weeks to order, I looked here. . .and I'm glad I did. This sub soiler is MUCH more solidly constructed than the local alternative I'd been looking for.
Wish it came with the burying attachment to drag in electrical/plumbing/etc, but I managed ok.
Worked about 8 digs with it, somewhere in the 900' of run, and no problems at all. I went through several forearm size softwood roots, and one poplar. . . no large stones or hardwood, but again, the shear pin is there for that reason.
Took a bit of assembly, and there's no actual directions, but if you're reasonably mechanically proficient, you'll figure it out just fine.

Using to pull in water and electrical pipe, works great. solid piece of equipment. no compaints.
Pulling with 27hp utility tractor has pulled very easy threw sandy soil, never had a power or traction problem.

just as described
Dug deep and worked great. Broke up the ground well and let my FEL dig quickly

Good subsoiler / rooter
After reviewing other subsoilers I chose this one for the shear bolt option, fab construction and other reviews. It works great as a subsoiler so I made another tooth with added cutting edges to shear off roots from stumps where I am cleaning fence rows. It has worked well for that also, unless I find a hardwood stump with stronger roots. The shear bolt does it's intended job and prevents tool or tractor damage. I am using a 32 HP 4X4 tractor.
Pleased with the prompt service from Northern Tool also.
