## Long description

Handheld Fertilizer Spreader THI 421 is a manual broadcast spreader designed to distribute granular fertilizers evenly across small lawns, garden beds, and allotments. The lightweight construction and straightforward mechanical metering system enable controlled application rates without batteries or complex setup. The THI 421 is intended for users who need a compact, easy-to-handle tool for targeted fertiliser application and maintenance tasks.
Advantages
The spreader provides simple, reliable performance through a mechanical metering mechanism that adjusts the flow of granules, allowing users to vary application intensity. Its handheld design offers mobility and precise placement near plants and borders, while the compact size makes storage convenient. The absence of electrical components reduces maintenance needs and increases durability for occasional seasonal use.
Suitable for
 Small lawns and residential turf maintenance
 Vegetable plots, flowerbeds and container gardens
 Allotments and community garden plots
 Targeted spot treatment of granular fertilizers and soil amendments
When it may not be suitable
This manual spreader is not intended for large commercial fields or extensive acreage where motorised or tow-behind spreaders are more efficient. Very fine powders or wet, clumped fertiliser may not flow well through the mechanical metering system and could require pre-conditioning or a different application method.
Key specifications
 Type: Handheld manual broadcast spreader
 Application material: Granular fertilizers and similar dry granules
 Metering: Mechanical adjustable metering system for controlled flow
 Design: Lightweight, handheld form factor for close-range application
 Operation: Manual — no batteries or electrical components
How to use
Fill the hopper with the recommended amount of dry granular fertilizer, set the metering control to the desired application rate, and walk the treatment area at a steady pace while operating the release mechanism. For even coverage, overlap passes slightly and avoid stopping while the discharge is open. Clean the spreader after use by emptying remaining product and brushing out the hopper and metering components to prevent clogging and corrosion.
What to consider before purchase
 Size of the area to be treated — suited for small to medium domestic plots
 Type and granule size of fertiliser to ensure compatibility with mechanical metering
 Need for portability and close-range precision versus requirements for larger motorised spreaders
Usage recommendations
Use THI 421 with dry, free-flowing granular fertilisers for best results. Calibrate the metering setting on a small test strip to confirm coverage rate before treating the entire area. Store the spreader clean and dry to extend service life and inspect the metering parts periodically for wear.
