Both the front and rear gangs can be indecently set for 0, 7, 14, and 21 degrees. A single pin allows you to quickly change and lock the front or rear gangs into one of their 4 positions. To change the angle, lift the disc harrow with the 3 point hitch, pull the safety clip from the bottom of the pin and remove the pin. The built in handles make it easy to slide the plate a hole or two in the desired direction. Drop the pin into the new position and reinstall the safety clip.
Here is another view showing how easy it is to adjust the gangs into any of the four available positions. Some disc harrows take up to 15 minutes to remove multiple nuts and bolts to accomplish this. I believe Bush Hog did a good job in making this an easy job. An operator is much more likely to make an adjustment in the field when it can be done quickly and easily....and doing so will yield better tillage and so better crop.
The tractor's 3 point top link can be attached using either a 3/4" or 1" pin. A pair of holes, one of which is 3+ inches above the other, provide the operator with a choice of optimum attachment points and should accommodate most any Category 1 hookup on the tractor. The plates allow for a 2" opening for the top link.
The notched blades on the 1D60 model are 18" in diameter. The front gang has 3 blades on each side and are spaced 9" apart. The rear gangs have 4 blades on each side and are spaced 7 1/2" apart.
As I write this, I've yet to put the disc harrow onto a food plot. The weather has been rain every other day since I bought it and I'm not looking to create a mud bog. I will update this write-up as soon as I get a couple of hours on it.
During this past week, I had the chance to open up a new half acre food plot and expand another. This was the first chance to use the new disc and it did very well, in my opinion. The half acre plot hadn't been worked for about 5 to 6 years and the other one hadn't been turned over for several decades. Both had been or still are being used for hay production. Needless to say, the disc did a better job on the new half acre plot.
The soil moisture was still good at the half acre plot. I wish the disc weighed a little more. I wasn't getting quite the penetration I was hoping for as seen in the above photo. My 4WD 28 HP tractor had no problem pulling the disc in low range. I probably could have managed it in mid range but that kind of ground speed wasn't necessary. With the diesel hitting about 2300 RPM in low range, the soil was rolling off the disc blades cleanly.
The other plot that hadn't seen any tillage for a couple of decades turned over fairly well. The first plot I did had a little more sand in the soil while this plot did not....so the roots held the compacted soil together. The end result was more clumps of soil when I deemed it finished. That being said, it was certainly good enough for a food plot. Since the ground had not been tilled for so long, I followed a suggestion to shorten the top link a bit. This causes the rear gang to lift a bit and transfer more weight to the front gang, thus causing better cutting by the front disc blades.
Here is a photo of the new half acre food plot. I did three passes length wise on the plot and finished it with a 4th pass done on the diagonal. This is on my nephew's property and he was very satisfied with the results. We used a different disc last fall when we made his other food plot and it was very, very lumpy.
While using the disc, I took the opportunity to adjust it several times. For the most part, I ran the field with both gangs adjusted to the most aggressive position.
In summary, the Bush Hog 1D60 disc harrow did a good job and I'm very satisfied with the results. Our land is not entirely free of rocks. Most of them are small and some go up to football size. The disc had no problem with them and typically rolled them out quite well. I had plenty of them to pick up after I finished the tractor work. I did find one that was big enough to cause the disc to roll up and over the rock. I flagged it for future removal....when my nephew comes to visit and I can make use of his muscles. LOL! I look forward to using it again as we increase our food plot count.
