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.

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.
