Scag SFC-21 21″ Kohler 5HP

Description

Scag SFC 21 Inch Commercial Push Mower with 5 HP Kohler Command

The Kohler-powered 21 inch SFC at 5 horsepower, priced below the Honda machine. It is the mid option in Scag’s commercial push mower range.

Commercial Rather Than Domestic

A commercial 21 costs several times what a homeowner mower of the same width does, and the difference is entirely in what happens after a thousand hours. Bearings, deck steel, engine specification and the controls are all built for daily use by someone who did not buy the machine. A domestic mower put on a commercial round lasts a season.

• Cutting width: 21 inches
• Engine: Kohler Command, 5 HP
• Type: commercial finish-cut push mower
• Deck: single blade
• Rated for commercial use

Small Engines Need Their Air Filter More Than Big Ones

A four or five horsepower engine has no reserve to spare, so a partially restricted air filter costs a noticeable proportion of its output rather than a fraction of a percent. On a mower working dusty verges and dry ground, checking the filter weekly rather than at a service interval is what keeps the machine cutting properly at the end of a summer.

Check the Cables Before the Season

Control cables stretch and their outers stiffen with age, and the symptom is a blade brake or throttle that no longer reaches its stop. Both are adjustable and both are safety related, so they belong in the spring check rather than in the list of things to look at when something feels wrong.

A Stiff Cable Is Usually Dirt

Grit inside the outer casing causes most of it, and a stiff cable that is ignored becomes a broken one at an awkward moment.

The 21 Inch Options

The SFC-21-7CV steps up to 7 horsepower for heavier growth, and the SFC-21-4GX is the Honda alternative. The SFC-21-5CV-ZS is a variant of this machine listed at a lower price.
