Engine, drive and deck
You've got two engines on either deck. One's Kawasaki's FX1000 EFI, rated 38.5 hp. The other's the Vanguard EFI at 994 cc, with Oil Guard and 40 hp. That's 1.5 hp more. Both draw from a 9.5-gallon tank.
EFI is electronic fuel injection. There's no carburetor to choke or adjust.
Parker HTG transaxles with 16cc drive motors push it to 13 mph forward and 5 mph in reverse. That's 2 mph more than the SRT-XDe.
The deck is reinforced 7-gauge steel, full-floating and 6 inches deep. It cuts from 1.5 to 4.75 inches in 14 positions. The 61-inch measures 62.5 inches wide.
Built for the crew that's out all day
Who's this for? A landscape crew, a property manager, anyone who cuts big ground most days of the week. Smart Ride puts the rear frame section on Winamac coil springs.
The full-suspension seat sits on adjustable TecsPak elastomer supports and a 360-degree floating platform. It rolls on 13x6.5-R6 radials up front and 24x14-R12 radials in back.
Which deck? The 72-inch covers more ground on each pass. The 61-inch, at 62.5 inches wide, is easier on the trailer and through gates. Count the gates on your route before you pick.
Both engines are offered on both decks, so the deck you pick won't lock you into one. Either way, it's a lot of mower to haul.
Weights run from 1,290 lb with the Kawasaki on the 61 to 1,336 lb with the Vanguard. Browse our mowers on j5tractors.com, then call the store about the deck size your work needs.
