Adjusting Deck Lift Assist Spring Tension
NOTE: Deck lift assist spring tension is adjusted at the
factory. If the effort required to raise or lower the
mower deck is not satisfactory, an adjustment may be
necessary.

MX15285
4. Measure distance (A) between the washers (B) on each
deck lift spring assembly.
The recommended factory setting is approximately 1
mm (1/32 in.) gap between the spring coils at the lowest
HOC setting.
Adjust Assist Spring Tension
NOTE: The Chariot LX is equipped with two deck lift
assist spring assemblies. Both deck lift assist springs
must be adjusted equally.
Do not overtighten the deck lift assist springs. If the
springs are compressed too tightly, the mower deck
will float too freely.
Decrease deck lift assist spring tension if operating in
rough terrain.
While positioned in front of the machine:
Turn hex nut (C) clockwise to increase deck lift spring
tension and reduce the effort to raise and lower the mower
deck.
Turn hex nut (C) counterclockwise to decrease deck lift
spring tension and increase the effort to raise and lower the
mower deck.
