GENERAL OPERATING INSTRUCTIONS CONTINUED:
(L)
To keep disc level transport wheels must be riding on ground gauging desired discing depth, as shown in Fig. 3.
If conditions are such that disc can not penetrate to maximum depth, do not raise transport wheels off ground as shown in Fig. 2. Raised
transport wheels may cause front of disc to drop causing front gangs to cut deeper than rear gangs.
Front of disc may drop because rockshaft and hitch levelling arm is linked. As the wheels are raised, the hitch levelling arm is pulled back
allowing hitch to float. If hitch is allowed to float it will not support front of disc allowing front gang to drop.
With front of disc lower than the rear, the front outside blades will cut much deeper than the front inside blades. This means that more of the
disc's weight is placed on the front outside blades, forcing them deeper into the ground.
Uneven and deep front gang penetration in tough conditions will place excessive strain on blades, gang bearings, frame and hitch, and will
lead to a premature failure of parts especially outside blades and bearings of front gangs.
IMPORTANT:
Operating disc with transport wheels off ground will cause uneven discing job and place undue strain on machine which
could lead to parts failure. Always operate disc with transport wheels on ground even if soil conditions will not allow disc to
penetrate to maximum depth.
