Troubleshooting Chart
Problem Cause Solution
Auger and/or impeller
stalls (will not turn)
Obstacles are entangled in auger and/or blower
housing.
Shut Snow Blower down and manually clear
auger and impeller housing.
Impeller jam nut is loose. Tighten impeller jam nut.
Quick couplings did not engage. Reconnect quick couplings to skid steer.
Hydraulic system is not engaged. Engage hydraulic system.
Hydraulic flow from skid steer or tractor rear
mounted hydraulic reservoir is inadequate.
Check hydraulic flow at the Snow Blower.
Skid steer or tractor rear mounted hydraulic
reservoir is low on hydraulic fluid.
Add hydraulic oil to skid steer or tractor rear
mounted hydraulic reservoir.
Hydraulic hose has a break. Replace hydraulic hose.
Hydraulic hose has an obstruction. Remove obstruction or replace hose.
Hydraulic line is pinched. Fix pinched line.
Hydraulic lines have air in them.
Engage hydraulics to Snow Blower until air is
purged from hydraulic lines.
Bottom of auger housing
is wearing.
Grader blade is worn. Reverse or replace grader blade.
Discharge chute won’t
rotate
Ice build-up around base of discharge chute. Remove ice.
Wire harness connections are loose. Reconnect wire harness connections.
Solenoid is not operating properly. Have solenoid inspected and repaired.
Hydraulics problems
Refer to hydraulic problems for:
“Auger and/or impeller stalls”
Discharge chute is
plugging
Ground speed is too fast. Decrease ground speed.
Auger motor speed is too fast.
Decrease motor speed at the flow control
valve.
Discharge chute throws
snow at the operator
Rotational stop bolts are on the wrong side of
the rotational stop.
Remove rotational stop. Rotate chute to
throw snow straight forward. Reattach
rotational stop.
Discharge spout does not
throw snow the preferred
distance
Discharge spout is set at the wrong angle.
Extend hydraulic cylinder to shorten throwing
distance. Retract hydraulic cylinder to
lengthen throwing distance.
Impeller is throwing small
amounts of snow
Not enough snow to fill the impeller.
This is normal when clearing snow fall that is
not very deep.
Auger motor speed is too slow.
Increase motor speed at the flow control
valve.
Ground speed is too slow. Increase ground speed.
Hydraulic motor is leaking
oil
Hydraulic motor seals are blown.
Have the hydraulic motor with leaky seals
repaired.
Skid shoes are wearing too
fast
Loader arms are not set to float. Set loader arms in float position.
Snow Blower is not parallel to ground. Level Snow Blower.
Snow Blower makes
intermittent clicking noise
Impeller jam nut is loose. Tighten impeller jam nut.
Auger flighting is bent or broken. Repair or replace damaged auger.
Impeller blades are bent or broken. Repair or replace damaged impeller blades.
Snow Blower makes
excessive noises or
vibrates excessively
Auger is contacting the ground.
Adjust Snow Blower to operate level.
(Parallel with the ground.)
Blowing dirty snow or refrozen melted snow. Blow only clean fresh snow.
Picking up road gravel and/or crushed rock.
Lower skid shoes to carry grader blade
above road gravel and crushed rock.
Obstacles are entangled in auger and/or
impeller housing.
Shut Snow Blower down and manually clear
auger and/or impeller housing.
End bearing is worn or damaged. Replace end bearing.
Auger is bent or broken. Repair or replace damaged auger.
Impeller blades are bent or broken. Repair or replace damaged blades.
Snow is left on the ground
Skid shoes are set too low. Raise skid shoes up.
