As long as the grass is mowed or thin, it doesn't have a problem. It chews thin or short grass up for the most part. It's when the grass is thick and little taller than normal that it gets caught in the rear sprocket. Meaning that the grass is still in the ground and entire clumps of it are pinched between the inside sprocket teeth and track. Not good on the gears.

The Leopard motor has gobs of power, but with the sprocket at the rear, clumps of grass are pulled up into them. It goes under the hull and spreads out into the track. Metal everything won't solve the problem.

Have thought about sharpening the sprocket teeth on the inside, or making some sort of hedge cutter for it tho'.
