2022 John Deere 648R

A well-designed mower deck can make the difference between just getting the job done and getting eye-catching results. The 7-gauge, 0.179-in. (4.6-mm) fabricated mower deck delivers a higher quality of cut in more diverse conditions to enhance mowing performance. Key features of the fabricated mower deck include: The mower deck is manufactured from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup. A compact footprint delivers greater maneuverability when working in tight quarters. A deep-deck design delivers excellent airflow so material is processed quickly and efficiently. A powerful vacuum effect is created by the deck's unique air-flow design, which pulls more grass upright so that the blades can cut more evenly. 48-in. to 61-in. (122-cm to 155-cm) decks come standard with an adjustable striping flap to enhance the after-cut appearance. A commercial-quality, 22-hp (16.4-kW) at 3600 rpm, air-cooled engine powers the QuikTrak™ Mower: Overhead valve design More horsepower and torque per cubic inch of displacement Better fuel efficiency Full-pressure lubrication with full-flow filter Reduces engine wear by ensuring proper lubrication, even when operating on hillsides or uneven terrain Filtered oil reduces risk of contamination for increased engine life V-twin design Fast starts Smooth operation Vertical shaft for efficient transfer of power to the transmission and mower Standard dual-element, canister-type, dry replaceable, heavy-duty air cleaner with secondary safety element Fuel pump for consistent and reliable fuel supply to the carburetor Air-cooled engine design for minimum maintenance and maximum reliability Standard cleanout ports for easy access to remove debris collecting in cooling fins Aluminum cylinder block Effectively dissipates heat Lightweight and strong construction Extends engine life due to elimination of debilitating engine temperatures Controls are color coded and logically placed to make them easy for the operator to find and use: Ground speed and direction are easily controlled by moving the two hand-lever hydrostatic drive controls forward or reverse. Speeds are infinitely variable up to 9.5 mph (15.3 km/h) forward and 5.5 mph (8.9 km/h) reverse. A positive neutral-lock position for the levers provides added safety. Two stationary reference bars are provided for operator convenience and security. Front reference bar is included to control speed and reduce fatigue from control lever operation. Rear reference bar is included to make reverse operation easy while maintaining operator confidence. Control levers return to neutral automatically for safety and convenience. Separate choke is easy to locate and use. Less adjustment is needed with the separate choke.
