If your L3540 is hydrostatic it has 28 HP at the pto. Mowing a 5 foot "bite" with a 6 foot mower still takes more power than a 5 foot mower due to the heavier blade inertia and the fact each blade is 6 inches longer and thus it has more leverage to slow lug your tractor down. If you want a 6 foot mower you can get one with lighter blades, as in the JD/Frontier 2072. It has .5 inch thick x 3 inch wide blades. Much lighter than the 4 inch wide on most 6 foot cutters. It has a smaller gearbox that also takes less force to turn. Bigger gears turning fast in heavy gear oil use power. Smaller gears use less power. There are some ways to give your tractor a boost in mowing. Mow higher. Just a inch or two helps. Vent your mower so it expels clippings better. Get your blades sharper. Use low lift blades.
I found my GL5040 also got stronger as the engine/transmission broke in. Not a huge "wow" but without a doubt it is stronger than when it was new. Its got 275 hours on it now.
You should also look at the mowing charts to see just how much you gain with a 6 vs. 5 foot mower. By the time you go slower for the 6 footer I don't think you'll gain much at all other than just in the operators imagination. The simple fact is that your time spent mowing a field is more about horsepower than the width of your mower. A 28 pto horsepower tractor will only mow as fast as 28 horses can. No real magic trick to speed it up other than the higher/sharper option that I've been able to find.
Not to hijack, but where can you find these mowing charts? Thanks,
