The Troy-Bilt TB-320 12AVC35U is part of the lawn mower & tractor
test program at Consumer Reports. In our lab tests, self propelled mower
models like the TB-320 12AVC35U are rated on multiple criteria, such as those listed below.
Reflects a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how completely the mower distributed its clippings over the lawn's surface.
Denotes a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how much clippings the bag held before it filled or the chute clogged.

Features & Specs - Troy-Bilt TB-320 12AVC35U
Forward speeds Some self-propelled mowers have one speed, usually about 2 1/2 mph; others have several. Still others have a continuous range, typically from 1 to 3 mph. Two or more speeds let you adjust to the terrain and grass.
Drive wheels Front-wheel drive lets you make U-turns by pushing down on the handlebar and swinging the mower around without disengaging the drive. The downside is less traction than you get from mowers with rear-wheel drive.
Deck size (in.) Most models have a deck size, or cutting swath, of 20 to 22 inches. There is no significant advantage from one size to another. A larger deck can cut more grass in a single pass, but in this size range the difference is negligible.

Engine size For gas-powered mowers, engine size in cubic centimeters (cc) provides a rough indication of the engine's power; electric models are rated in volts (for cordless) or amperes (corded). A larger number for either a gas or electric model, however, does not necessarily result in better cutting performance.
Engine manufacturer Stated manufacturer of a gasoline engine. For some mowers the engine manufacturer is not documented and is listed as "unknown."
Briggs & Stratton
Electric start Starts a gasoline-powered engine with the turn of a key by the operator. An electric start is powered by an on-board battery that requires periodic charging.
Blade brake clutch Allows the gasoline engine to continue to run when the operator leaves the area behind the handlebar to empty the grass-clipping collection bag or to move an object in the path of the mower. It saves wear on the engine by reducing stopping/restarting cycles.
