The DR Field & Brushcutter 15.5 HP PRO 26 has 50% more power than the 10.5 HP model and adds electric-starting, a full pressure oil pump for better mowing on slopes, more brush-busting capacity (including saplings up to 2.5" thick), and Power Steering.
Power Steering makes the 15.5HP PRO 26 the nimblest DR of all. Each wheel has an independent disc brake that lets you turn on a dime. Plus, if you're mowing across slopes, you can feather the uphill brake to improve the machine's tracking and traction. The 15.5 HP PRO 26 is a great choice for hilly properties because it includes a full-pressure oil pump–so you can mow on slopes of up to 20° and be assured of plenty of good lubrication to all parts of the engine.
This engine is equipped with a convenient turn-key electric starting, so you never have to leave the operator's position to start or stop the machine. This model's extra displacement (500cc vs. 344cc for the 10.5 HP model) also provides the extra "oomph" needed to power through saplings up to 2.5" thick! The ability to accept various attachments makes the DR Brush Mower the most versatile brush mower on the market.
