Strawblowers
Strawblowers, Straw Blowers, Hay Blowers, Straw Mulchers or simply Mulchers are all the same equipment. All Strawblowers make it possible to achieve a 30-40% material savings and to achieve up to an 80% labor savings vs hand mulching straw. The key is to buy the Strawblower that is the best value for the money.

Strawblowers cost effectively mulch baled straw and disperse it on the ground as an evenly distributed blanket. The results save contractors both time and money by reducing & using labor and materials more efficiently. Strawblowers are a cost effective tool for job site erosion control compliance as mandated by federal EPA requirements. Mulched straw also provides insulation to newly planted seed.

Grun Model SB4 Strawblower
The Grun model SB4 Strawblower is aerodynamically engineered and features a leaf and debris vacuum option, a nine gallon fuel tank and heavy gauge steel throughout. The drive system generates a discharge velocity exceeding the wind speed of a Class 5 Hurricane. The leaf and debris vacuum option extends the usage season by 50 percent. Both the fuel tank and the battery are protected by metal for greater safety.

Durability
The Grun model SB7 Strawblower uses the heaviest gauge steel. Heavier steel means greater durability. Because heavier steel is more durable it extends the life of the equipment, which keeps resale values higher.

"Slot & Groove" Joinery
All Grun products are assembled utilizing our unique "slot & groove" joinery system with full welds throughout. Grun parts are all laser cut like puzzle pieces - there is only one way that Grun parts can be assembled which results in unsurpassed durability and manufacturing consistency.
