Modifying a finishing mower

Hi. I have a 6ft Worksaver brand finishing mower. It works good but the highest cutting height is about 4", which is a little too low for the long prarie grass I have on my land.

I've determined that if I remove the wheel "legs", flip them upside down, and re-drill the mounting holes I can add 6" inches to the cutting height. Would this plan work? Or is there something about a 10" cutting height that I'm not taking into consideration?

Has anyone else modified their finishing mower to cut higher?

I suspect that the reason that the quality of the cut diminishes at higher cutting heights is due to the fact that the deck is designed to create a lifting action on the grass and when the higher setting upsets this the grass can actually get blown down away from the cutting blades. Hopefully someone with more knowledge of this will be able to confirm or debunk this theory.

There are a couple of things that I can think of that you may want to consider besides a potentially poor quality of cut. The first is shielding from grass and objects thrown from under the deck. When run close to the ground the deck tends to keep projectiles from getting out from under it. The higher the deck is the more chance there would be to throw something. Second, how will the higher position affect the angles of the PTO shaft? While a PTO shaft is capable of turning in a relatively wide arc, the loads, the wear and the vibration will increase significantly as the running angles increase.

The one thing that you are doing right is to use the inverted caster wheel assemblies to raise the ride height of the deck. What you don't want to do is to mow with the deck suspended by the three point - in other words you want the wheels to support the deck.
