Mower Deck Height
The Model 325EFK Articulator has a standard mower deck height range of 1" to 4 1/2", in
1/4" increments. If you wish to change the mower deck height, do so before attempting to
operate the Articulator.
The mower deck height adjustment lever has (1) permanently fixed spacer, and (16)
adjustable spacers, each equal to 1/4" deck height adjustment. The deck is at its mini-
mum height (1") when only the fixed spacer is in front of the lever lock bracket. Each
adjustable spacer placed in front of the lock bracket raises the deck height by 1/4”, up to
4 1/2". The spacers which mark the 2", 3", and 4” deck height positions are knurled for
quick identification.
To adjust the mower deck height, turn the spacer locking knob on the height adjustment
lever counter-clockwise until the spacers and lever are loose. Raise the lever from the
locking bracket and adjust the spacers to the desired height setting. Each spacer placed
in front of the lock plate will indicate an additional 1/4” of deck height. When the desired
deck height setting is reached, place the lever back into the locking bracket and turn the
spacer locking knob clockwise until the spacers are tight.
An additional 1/4” of deck height can be attained, for a maximum height of 4 3/4”, by
removing the 1/4” spacers from ABOVE all the wheel yoke collars and placing them
BELOW the collars. This will raise all of the deck height settings obtained with the deck
height adjusting lever by 1/4” respectively. The deck height range will now be 1 1/4” to 4
3/4”, in 1/4” increments.

Gauge Wheels
Verify proper function of all mower deck gauge wheels. The wheels should turn freely
without excessive side-to-side motion, and be free of debris. Clean, adjust, or replace as
necessary.
Check that each wheel swivels freely in the shaft pivot collar, and the bushings are in
good condition. If any wheel does not swivel freely, clean and grease the shaft collar
assembly. Replace the bushings if necessary.
NEVER attempt to change the cutting deck height while the engine is
running!
