Description

Stihl HS 45 18″ Gas Powered Hedge Trimmer

Dependable 27.2cc 2-Stroke Gas Engine. Dual-Reciprocating 18-Inch Double-Sided Blades. Signature STIHL Anti-Vibration Comfort System.

The STIHL HS 45 18" Gas Powered Hedge Trimmer brings reliable cutting speed, exceptional maneuverability, and perfectly uniform sculpting directly to your property care routine. Purpose-built to eliminate the exhausting shoulder fatigue of stiff manual pulls, jagged cuts from single-action blades, and the constant reach limitations of outdoor extension cords, this premium 2-stroke gasoline hedge trimmer stands as an elite landscape tool. It equips suburban homeowners, garden hobbyists, and estate caretakers with a rugged, high-torque platform explicitly optimized to shape chest-height privacy hedges, trim overgrown boxwood shrubs, prune back dense garden bushes, and slice clean corners around stone walls and walkways.

Outstanding user comfort and rugged structural durability form the engineering core of this highly efficient STIHL HS 45 Hedge Trimmer. Driven by a smooth-running 27.2cc engine delivering a solid 1.0 bhp, it powers its high-velocity dual-ground reciprocating blades to deliver fast, immaculate cuts through dense yard foliage. Starting the tool is engineered to be entirely painless thanks to the built-in ElastoStart™ shock-absorbing handle and a manual fuel pump bulb that drastically reduces the number of initial pulls required. To protect your muscles and joints during extended yard sessions, the tool features a specialized anti-vibration system utilizing rubber dampeners to isolate engine rumble away from the grip handle, while a integrated single-lever master control keeps your thumb in constant contact with all starting and stopping functions.

Why the STIHL HS 45 Gas Trimmer Rules Occasional Yard Care:

  • Immaculate Double-Sided Blades: Features a dual-ground 18-inch blade geometry that allows you to sculpt flawlessly in horizontal, vertical, or sweeping corner motions.
  • Shock-Absorbing ElastoStart™: An integrated spring cushion inside the starter grip absorbs compression peaks to prevent harsh jerking on your wrist and arm.
  • Ergonomic Single-Lever Operation: Combines the choke, throttle lock, and run switch into a single accessible lever so you never have to take your hands off the steering frame.
  • Advanced Vibration Dampening: Uses precision-engineered buffer elements to minimize handle oscillation, preventing premature numbness and back fatigue.
  • Impact-Resistant Polymer Casing: Built with a lightweight, high-tech polymer housing that resists external impact, blocks chemical corrosion, and keeps tool weight at a balanced 10.4 lbs.

Frequently Asked Questions

+ What type of fuel mixture does the STIHL HS 45 engine require?
The HS 45 features a high-performance 2-cycle engine that requires a strict 50:1 mixture of high-quality unleaded gasoline (minimum 89 octane) and 2-stroke engine oil. For optimum engine longevity and hassle-free starting, STIHL highly recommends using pre-formulated STIHL MotoMix® fuel, which is completely ethanol-free and stays fresh in storage for up to two years.
+ How do double-sided blades compare to single-sided hedge trimmer blades?
Double-sided blades provide maximum cutting efficiency because they allow you to cut in both left-to-right and right-to-left directions, as well as vertical upward and downward strokes. This dual-edge geometry gives you superior control when navigating tight corners, sculpting rounded ornamental shrubs, or executing detailed landscape work.
+ How often do I need to lubricate the internal gearbox gears?
To protect your tool from friction wear and high-heat damage, STIHL recommends lubricating the gearbox roughly every 50 hours of active use. This is easily done by removing the specialized gearbox screw plug located directly on top of the transmission housing and squeezing in genuine STIHL Gear Lubricant specifically formulated for hedge trimmers.
+ Does this gas powered hedge trimmer arrive with a blade safety cover?
Yes. The STIHL HS 45 package includes a heavy-duty plastic blade scabbard (cover) that slides firmly over the 18-inch dual-sided cutting bar. This cover protects the sharpened teeth from dulling and moisture during off-season storage, while shielding your hands from accidental cuts when transporting the trimmer around your property.
