Standard Features

22 hp (16 kW) 725 cc Kohler® V-Twin Engine
 Kohler® V-Twin engines provide dependable performance and reliable starting, along with increased durability. AutoChoke means no need to choke. Just turn the key to start.  
Heavy-Duty Rear Engine Guard
 This heavy-duty steel guard protects the engine from branches and debris as you maneuver around your lawn.  
3 gal. (11.4 l) Fuel Capacity
 All TimeCutter® riding mowers feature a large 3 gal. (11.4 l) fuel tank for more mowing with fewer fill-ups. Knowing when to fill up is simple thanks to the translucent tank, which also helps to prevent overfilling.  
42 in. (106.7 cm) Mowing Deck
 Toro's 4 in. (10.2 cm) deep, top discharge deck design provides superior cutting performance in all conditions. Anti-scalp wheels allow the deck to float over the turf and reduce scalping. Create your own natural fertilizer by adding a Recycling Kit® or make yard clean-up a snap with an optional Twin Bagging system.  
Washout Ports
 Deck washout ports create a pressure washer under your deck providing quick cleaning, maintaining optimum airflow for optimum cutting performance.  
Heavy-Duty 10 ga. Uni-body Steel Frame
 The lower the gauge, the thicker the metal, which is why we use heavy duty 10 ga. steel. The uni-body steel frame provides the optimal balance in rigidity and flexibility for quick, highly maneuverable mowing conditions.  
Hitch Kit Standard
 Hitch kit comes standard on all TimeCutter® models. It's easy to increase the versatility of your zero turn mower by attaching a dump cart, de-thatcher, fertilizer spreader or other Brinly-Hardy attachments. (Attachments sold separately.)  
Dual Hydrostatic Drive System
 Independent hydrostatic drive systems provide responsive maneuverability and zero turning capabilities. These independent drives are anchored to Toro's unibody frame and reinforced with a cross member for lasting durability and performance.  
Smart Speed® Control - Trim, Tow, Mow
 Toro’s Smart Speed® control system lets you choose from three ground speed ranges for optimal performance. Use low TRIM range to trim closer for maximum time savings, choose medium TOW range for towing attachments, or select high MOW range to mow large open areas and finish quickly.  
Save on Average 45% of your MowingTime
 The Toro TimeCutter® cuts your mowing time almost in half*, which means less work for you and your mower. You’ll not only have more time to enjoy, you’ll extend the working life of your mower.  
Automatic Parking Brake
 Automatically engaged when the control arms are moved outward. Simplifies operation by eliminating a separate parking brake.  
18 in. Extra Tall Seat
 When you're mowing for an extended period, there's no substitute for a good seat. The 18 in. extra tall seat offers premium support during longer mowing sessions.  
Non-Slip, Easy-to-Clean Floor Pan
 The pierced floor pan is perfect for homeowners who like their mower to look as nice as their lawn. Simply hose down the floor pan after each use and keep your TimeCutter® looking as good as new. The non-slip pierced extrusions also provide an additional measure of safety.
