Bigger is NOT better when it comes to mower size

But they are also very heavy and can cause soil compaction and severe tracking in your lawn if you are unable to change up the mowing patterns. Lawns are also much more succeptible to scalping and tire scuffs with larger mowers.

For riding mowers using a manual clutch, the mower blades are engaged by manually shifting a lever that moves a pulley assembly to tighten the blade drive belt. The rotating engine shaft will then drive the belt, which in turn, rotates the pulleys to spin one or more cutting blades.
Blade brake clutch (known as BBC) is a feature on petrol lawnmowers that allows you step away from your lawnmower without shutting off the engine. The blade brake clutch disengages the blade and stops it turning, whilst the engine continues to run.
Turn the adjusting lock nut clockwise to raise the mower and counterclockwise to lower it. Measure from the blade to the ground again on both sides and adjust until the difference between the blade tip heights are within ⅛ -inch. Rotate the blades so that their direction is now front to back.
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.
Riding mowers and lawn tractors have an average cutting width between 36 and 54 inches, whereas the standard push lawn mower width is around 16 to 30 inches.
Mowers of the type displayed usually vary in width from 20 to 24 inches (51 to 61 cm).
