All Seasons Equipment 103150 - 36" Manual Gravel Spreader, 3 Wheels

The ASE 36″ Manual Gravel Spreader (3-Wheel) is a manually operated gravel/spread ballast unit designed to evenly distribute pea gravel or ballast rock over flat surfaces or rooftops. It features an adjustable gate allowing application of different gravel thicknesses up to 2½ inches of ballast, giving flexibility depending on ballast requirements. The unit holds up to 6 cubic feet of material and weighs 100 lb, providing a balance of capacity and portability. Its 3-wheel design increases maneuverability and ease of use — helpful for rooftop crews needing efficient gravel distribution without the use of powered equipment. The spreader is ideal for small to mid-size ballast jobs or jobs where power equipment isn’t practical.

Q: How does the adjustable gate help control gravel usage on a roof?
A: The gate allows the operator to fine-tune the flow rate, preventing over-application and helping achieve consistent ballast coverage while reducing material waste.

Q: Can this spreader be used effectively on uneven or slightly sloped roof surfaces?
A: Yes, the three-wheel layout provides stable support, but best results are achieved when the spreader is pushed in controlled, straight passes to maintain even distribution.

Q: What type of gravel size flows best through the spreader without clogging?
A: Pea gravel and small ballast stones work most efficiently; oversized or irregular stones may restrict flow and reduce spreading consistency.

Q: Is the spreader suitable for small or confined rooftop areas?
A: Yes, the compact 36″ width and 3-wheel design allow operators to work in tighter spaces where larger powered equipment may not fit, while still maintaining smooth, even spreading.
