IHC #9 Mower rock guard number

Hi Mike, they will also have a MC 2041 which is a traditional guard with ledger plate. On a well tuned mower these guards will work well also. On the double guards I have been using this year I been seeing a little clumping of chewed grass caught between the top of the knife and the guard. Some times this leads to plugging and sometimes it doesn’t. It seems to be more common when mowing in wet conditions as things looked clean in dry conditions. (I know it sounds weird but I have been doing a lot of mowing in wet conditions.) I have taken the knife out and used a cold chisel to open the guard just a little bit. Some of them had less than a 1/16 above the knife. Now they all have about 3/16″ . As you can see I didn’t open them much, but I think I made them run better. I have also been experimenting with the L600 adjustable hold downs a little. When you have the first hold down on the second stub guard it is too close to the knife head. Even if it doesn’t appear to hit it, it will when the knife is pushed back by the hay. Solution is to cut the inner end of the clip right off. Just the piece that covers the back edge of the knife. Those back edges of the clip sometimes clamp down hard on the new knife. Possibly the knifes are thicker? I have been using a grinder to grind the under side just on the ends were the they cover the back edge of the knife. I am seriously considering starting to cut those off all the hold downs. I will try and cut a few off some time this week and see what they do. I have been running two mowers through tough conditions and they have worked well. I think my double guards with the super seven (large teeth) is pulling the easiest of all, but it did have one day where it wanted to plug in heavy wet grass. I think opening those guards fixed that, but I will probably find out this week end. Donn
