· Loosen chain shield (A) by loosening four lock nuts (B) on chain shield.

· Slide chain shield right or left until deflection measurement is right.

· Hold chain shield in place and tighten nut.

7. Rotate snowblower several turns and make sure chain has at least 4.7 mm (3/16 in.) deflection at all times.

8. Lubricate chain with John Deere TY6240 Chain Lube Spray or equivalent.

9. Start engine. Run snowblower briefly to distribute oil.

10. STOP engine. Wipe off excess oil.

Replacing Shear Bolt

When auger hits an object, shear bolt may break. This helps prevent damage to rotor and snowblower. If you break a shear bolt, do the steps listed below:

IMPORTANT: Avoid damage! Replacement shear bolts MUST BE same as original shear bolts on your snowblower:

·Softer bolts may shear too easily.

·Harder bolts may not shear: snowblower may be damaged.


1. DISENGAGE PTO to stop snowblower immediately.

2. STOP the tractor.

3. Lower snowblower to the ground.

4. LOCK the park brake.

5. STOP the engine.

6. Wait for ALL moving parts to STOP.


M93538

7. Remove broken shear bolt (A), one on each end, or (B) in center.


M55265

8. Turn auger or blower impeller to line up holes in shaft. Remove spare shear bolt (C) from snowblower.

9. Install bolt and nut. Tighten so that the two paddles that the shear bolts connect are touching. DO NOT OVERTIGHTEN nut.

10. Find and correct the cause for shearing.

Reversing and/or Replacing Scraper Blade


M55267

1. Check scraper blade for wear or damage.

2. Raise snowblower.

M55269a

2. Loosen two lock nuts (C), from threaded studs on discharge chute.

NOTE: For ease of reassembly and proper cable routing, remove one cable at a time.

3. Remove each cable (D) from snowblower.

4. Remove cables from pulleys (F).

5. Install new cables on pulleys. (See Replacing Discharge Chute Cables in this section.)

Replacing Discharge Chute Cables (Right-Hand))

NOTE: For ease of reassembly and proper cable routing, replace one cable at a time.

When replacing discharge chute cables, route RIGHT-HAND cable around snowblower FIRST.

IMPORTANT: Avoid damage! Hydraulic cylinder plunger MUST BE in the RETRACTED position (all the way in the cylinder) when beginning this procedure.


1. Turn snowblower discharge chute to the left (as viewed from the tractor seat.


M55286
