Mowing Not happy with cut of new 1505 mmm

[Lookinglassfalls]

I have a new 1526 Massey Ferguson with a 60" 1505 mmm. I love the tractor, but am not happy with the cutting performance of the mower. Has anyone found blades that will work with this deck besides the Massey blades? I am unhappy with the cut I am getting and believe a blade with a little more lift would do a better job. I have called Gator and Mamba and have been told nothing they make matches my mower. The best I can tell, the blade measures 20 13/16" and has a 20 mm center hole. Has anyone tried a 21" blade on this deck? Any help or advice is much appreciated!

If you like everything but the blade performance, then the solution is new blades. Taking 3/16 off the blades would not be a huge chore. 3/32 per side might not even matter. A three blade setup might have enough "slop", because of the staggered blades, that there won't be any blade to blade contact.
Just rotate the blades to the point where they are closest. Measure the distance and decide if there is enough room. I would not want them millimeters apart because of the chance of spindles flexing or wobbling slightly, but you should quickly know if the new blades would work. Of they need to be trimmed 3/32 per side.
If you do trim them, make sure you balance.
