The DR Power Equipment Pro 18 in. Rear-Tine Rototiller is a top-of-the-line, walk-behind rototiller that gives you the convenience of dual-tine rotation, allowing you to easily switch between forward and counter-tine motion. For tilling or cultivating in established gardens, go with forward rotation. Switch to counter-rotation for sod-busting or loosening compacted soil. Either way, the self-propelled, tractor-style wheels pull the DR PRO XL Rototiller along, making the job easy on you. The drag stake provides extra resistance and can be raised and pinned in place when not needed. It features an 18-in. tilling width and up to 11-in. tilling depth.
