Stability Data
T he follo wing tables list the maxim um slope recommended for the traction unit in the positions listed in
the tables . Slopes o v er the listed deg ree ma y cause the traction unit to become unstable . T he data in the
tables assume that the loader ar ms are fully lo w ered; raised ar ms ma y affect the stability .
In eac h attac hment man ual is a set of three stability ratings , one for eac h hill position. T o deter mine the
maxim um slope y ou can tra v erse with the attac hment installed, find the deg ree of slope that cor responds
to the stability ratings of the attac hment. Example: If the attac hment installed on a TX 420 traction
unit has a F ront Uphill rating of B , a R ear Uphill rating of D , and a Side Uphill rating of C , then y ou
could dri v e forw ard up a 205 slope , rearw ard up a 125 slope , or sidew a ys on a 145 slope , as listed in
the follo wing table for the TX 420 traction unit.
