I'll disclaim havng much mechanical skill and I have basic hand tools and a flat concrete slab garage to work in. My LT's operating manual is mum on how to raise the deck beyond the max cutting setting while still keeping the ability to disengage the blades with a slack belt.
That said, I'd like to raise my deck on a relic 1995 MTD Yard Machines lawn tractor with a 14.5 HP engine, 42" deck and 6-speed transaxle. Perhaps I need to adjust the belt tension, but my highest mowing setting right now (where the belt is fully tight) is two slots down from the "straight up" blades disengaged position. At two slots, down, I'm only at 2.5 inches of cutting height and I'd like to be at 3.5 or 4.0 inches or so.
At my current configuration, when I try to disengage the blades completely, the forward position of my deck grazes the engine pulley, causing intermittent sparks, and the blades still turn slowly. The first slot down acts like a partial disengagement of the blades and the cutting height at that spot would be 3.0 inches but the belt is not tight enough to drive the blades at full speed.
Looking at the deck lifting mechanism, there are no higher rear holes available on the hangers. The front hangers have higher holes available. If I raise the front, I'll need that much distance and more for the rear as I want to be able to pitch my deck down by 1/4" in the front.
What should I do next after making sure my tires are inflated properly? I don't think I should lower my anti-scalp wheels, as I don't believe they are designed to bear the full weight of the deck all of the time, correct? I don't think I could jury-rig a roller to support the deck like a Simplicity, as I don't have welding equipment or ability, and I'm hurting for space between the deck and right rear wheel since my twin blades are offset and the deck is shaped somewhat like a parallelogram.
A bit off of my topic, but I am interested in mounting a striping device on my old LT once I get the deck height challenge figured out. With the lack of space noted above, I think I'm consigned to mounting a roller or a flap on pivoting arms just behind the rear wheels. If anyone has tried to dress up a pig and put a striping system on a MTD/Huskee/Troy-Bilt with offset twin blades, I'd be interested to know how you did it. I am planning to have the striper cover the space between the inner sidewalls of the rear tires since they already leave their own stripes. I have a piece of truck mud flap available and found a 21 inch steel conveyor roller in a scrap yard this week, so depending on time or dough for mounting hardware, I could probably pick either method and be satisfied.
Thanks in advance.
