McLane 20-5.50GT-10-GK Greens Keeper Reel Mower Review

The name carries the whole machine. 20 is the cutting width in inches, 5.50GT is the Briggs & Stratton 5.5 GT engine, 10 is the number of blades on the reel, and GK stands for Greens Keeper.

In the box you get the grooved roller, which helps to level and compact soil in the spring, ensuring consistency across the lawn; the B & S 5.5 GT engine; an all-steel, heavy duty chassis; and an induction heat treated bed knife. It is a gas-powered walk-behind unit, finished in red.

What the grooved roller does

The grooved roller helps level and compact the soil in the spring and keeps the cut consistent across the lawn. On a lawn mown short, small dips and rises show up immediately, so a roller that presses the surface even is what keeps the finish uniform from one pass to the next.

The machine is purpose-built for ultra-precise cutting of Bermuda, Paspalum and other premium turf grass. A reel cuts like a pair of scissors against a fixed bed knife, so grass is sheared cleanly instead of torn, and the finish stays even at heights where a rotary mower starts to struggle.

A cut that goes down to putting-green height

The minimum adjustable cutting height is 1/8 inch (0.32 cm). That is the range where a reel mower earns its place: a lawn kept that short needs a clean shear, not a blade whipping through the tips.

Cutting parts built to last

The reel and the bed knife are both induction heat-treated and precision-hardened for durability. These two parts are the heart of any reel mower, and hardened steel is what keeps the scissor action true over seasons of use.

Traction and power delivery

Rear roller drive gives positive traction, and the belt and chain drives are built for reliability and consistent, smooth mowing. The Touch-A-Matic engine clutch controls make starting and stopping the reel and the drive straightforward, and the all-steel heavy-duty chassis holds the whole assembly rigid.

Every strength here has a flip side, and the flip sides matter before you buy. The machine weighs 180 pounds, which is why it holds a line and cuts cleanly, but it also means it is not a mower you toss around. Expect to work at the ends of passes and on turns.

A narrow deck means more passes

At 20 inches wide, the deck covers less ground per pass than a wider machine would. On a small, fine lawn that is fine. On a large one it adds time to every mowing session, and you will be mowing often anyway.

Built for fine turf, not rough grass

Its intended use is ultra-precise cutting of Bermuda, Paspalum and premium turf grass. It is not the tool for a rough, tall or mixed lawn, and it is designed around a maintained, level surface. The grooved roller helps consistency, but a reel mower cutting low needs even ground underneath it.

Reel upkeep is part of ownership

Reel mowers at this level need regular backlapping and reel-to-bed-knife adjustment to keep cutting cleanly. That is the nature of a reel, not a defect of this model, and it is ongoing owner work.

Changing cut height is a deliberate job

The cutting height runs from 1/8 inch (0.32 cm) at the minimum to 2-1/8 inches (5.4 cm) at the maximum. Moving across that range is not a single dial you flick; plan on setting the height you want and leaving it there for the season.

Read the numbers together and the machine's character shows. A 20-inch cut and 180 pounds mean a compact but substantial tool: it fits through a gate and stores against a wall, yet it takes real effort to lift and to swing around at the end of a row. The 1/8 to 2-1/8 inch (0.32 to 5.4 cm) range means it can go very low for a putting-green look, and it can also be raised to a more forgiving height when the lawn is under stress.
