The Scag Tiger Cat has separate pumps and wheel motors, the pump outputs are controlled by the lever positions. The Tiger Cat is a 10 MPH machine, but most folk don't mow that fast, 7.5-8.5 MPH depending on lawn conditions. Cast iron spindle housings and three plys of 10 gauge metal where the spindles are mounted. Collection system available which mounts on the deck discharge chute and the blower discharges into a three bag setup that hangs on the rear of the machine. Striping kit also available. Blades are held into the spindles by a 9 1/2" long, 5/8" diameter bolt with the nut on the top of the spindle drive pulley. Mulching blades and a block off plate that can be opened or shut by the operator also available. If you are interested in a collection system, then I recommend the Kawasaki FX engines with the two stage HD engine air filtering system, and also if you mow in a dusty environment.
