Experienced gardeners share their insights in answering this question :
When you put the new blades on did you notice if they were even with each other? the 42″ decks have a tendency to “warp” inward on the left side. this causes the left blade to ride at an angle to the right blade – there is a tool to correct this, but not all shops have it – sometimes you can remove the deck, flip it over and wallop the inside edge of the left mandrel until the blades are even – a 2 lb. sledge works well for this

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Locate the attachment lift lever on the right side of the steering wheel. Press down on the plunger at the top of the lever, and move the lever forward to raise the mower deck or backward to lower it.
Pull the wheel adjuster lever toward the wheel to unlock it from the tooth. Move the lever left or right to raise or lower the mower deck.
A perfectly tight mower belt can rotate without slipping off but not cause the engine to over-exert and overheat. If the belt does not slip off while working and is not producing unfavorable sounds that indicate wearing off of the belt, then that is the perfect tightness for it.
For most effective results, a lawn mower deck should have a pitch, or height difference of 1/8-inch to 1/2-inch between the front of the deck to the back of the deck. Naturally, this makes the sweet spot about 1/4-inch of pitch, depending on the mower model.

Dual-lever, 6 position height adjustment makes it easy to change cutting heights from 1.25″ to 3.75″ high.
Mower deck gauge wheels should be properly adjusted to prevent scalping grass on uneven terrain. The bottom of the wheels should sit approximately 1/8-1/2 of an inch from the ground, depending on your cutting height.
