STORAGE

STORAGE RECOMMENDATIONS

•Lower the snow thrower to the ground.

•Remove the snow thrower from the tractor.

•Clean the snow thrower thoroughly. Wash off any salt deposit which may have dried on the thrower and housing.

•Any bare metal that has become exposed should be painted or coated with a light oil to prevent rust.

•Store in a dry place.

REMOVING THE SPIRAL AUGER HOUSING

•Lower the snow thrower to the ground.

•Remove the attachment pin. See figure 29 on page 15.

•Lock the snow thrower's lift handle in the down position to decrease belt tension.

•Release the spring tension from the auger belt idler arm on the bottom of the clutch/idler assembly.

•Remove the auger drive belt from the clutch/idler assembly. See figure 31 on page 15.

•Pull the spiral auger housing assembly off of the tractor.

ADDITIONAL PARTS TO REMOVE AT END OF SEASON

•Remove the clutch/idler assembly. (The two hanger brackets and the two shoulder bolts may be left attached to the tractor frame.)

•Remove the drive belt from the engine pulley.

•Remove the engine pulley keeper and replace it with the tractor's original engine pulley keeper (rod or cable operated attachment clutches only).

•Remove the engagement rod from the tractor's clutch arm (rod operated attachment clutches only). See figure 11 on page 9.

•If a rear mounted attachment is to be used, remove the rear weight tray by removing the bolt from the tractor hitch and loosening the two bolts fastening the tray's side braces to the tractor. Be sure to retighten the two bolts in the side of the tractor. See figure 33 on page 16.

•If a front mounted attachment is to be used, remove the side plates from the tractor. Be sure to assemble bolts back into the empty holes in the tractor frame. See figures 1 and 2 on page 6.

TROUBLESHOOTING

PROBLEM	CAUSE		CORRECTION
Spiral augers don't turn	1.	Upper or lower V belt too loose	1.	Increase tension on V belt
	2.	Upper or lower V belt broken	2.	Replace V belt
	3.	Shear bolts are sheared.	3.	Replace shear bolts
Clogged discharge chute	1.	Tractor ground speed too fast	1.	Use lower tractor gear
	2.	Tractor throttle set too low	2.	Increase to full throttle
	3.	Snow too deep	3.	Raise the snow thrower

Snow thrower stalls tractor engine	1.	Object jammed in spiral auger	1.	Stop engine, disengage the snow
				thrower clutch and clear the auger
	2.	Hard or heavy snow	2.	Increase to full throttle and

Front wheels slide instead of steering	Not enough traction at front wheels		1.	Increase scraper plate clearance
				by lowering skid shoes
			2.	Pull down on lift handle to
				increase weight on front wheels
Snow thrower rides up over snow	1. Tractor ground speed too fast		1. Reduce ground speed
	2. Bottom snow is icy or hard packed		2. Lower the skid shoes so that front
