Rayco RG37 Stump Grinder - Petrol 37hp Engine With petrol engine power of 37hp the Rayco RG37 self-propelled stump grinder is what professionals have relied on for years. To maximise visibility while cutting, the RG37 has its drivetrain located on the far side of the cutter wheel. Rayco's exclusive, swing-out control station gives operators the best view while cutting and swings in-line with the machine for travel through gates. Wide, floatation tyres with bar tread give the RG37 a firm grip on the terrain, and dual wheels can be added for extra stability. Rayco's exclusive slewing ring pivot design lowers the centre of gravity and lets the RG37 cut at maximum depth across the whole swing path.
