2004 is the first year for the RZT. There are two models RZT17 and RZT22. Now for the ‘05 model year is
Kohler Command 19 HP model witha 50” deck.
This series of riders has the unique feature of not having to reset the PTO switch if the end users tries to
mow in reverse. Once one lapbar is moved in to neutral
or forward the PTO will turn back on.
The “RZT 17” has a 17 HP Briggs & Stratton Intek
which is a single cylinder engine with full pressure lubrication. The engine drives the dual hydrogear EZT
Hydrostatic transmissions and the electric PTO. The
PTO runs the 3-in-1blades on the 42” twin blade
stamped deck. On the front of the stamped frame is a
large pivoting front axle. All this with the 3 gallon fuel
tank will provide many hours of fun and relaxing mowing.
1. DECK LEVELING
1.1. To adjust the deck pitch, front to back, loosen or
tighten the jam nuts located on the front stabilizer bracket using a 15/16” socket and a 15/16”
wrench. The correct deck pitch should be 1/8” to
1/4” lower in the front than in the back, as measured from the blade tips. See Figure 1.1.

1.2. To level the deck, side to side, loosen the screw
on the left side adjustment gear using a 1/2”
socket. Using a 3/4” wrench, run the gear up or
down as necessary until each outside blade tip
is the same distance from the ground.
See Figure 1.2.

The “RZT 22” is very similar to the RZT 17 except for
the twin cylinder, 22 HP Briggs & Stratton Intek. There
are also 4 wheels, instead of 2, on the 50” triple blade
stamped deck.
All versions of the Cub Cadet RZT (and White ZT) are
bagger capable.
