ASSEMBLY INSTRUCTIONS 
 
 1. 
#740:  Turn the bottom tube weldments (#9) as shown in drawing and slide them 
into the sleeve welded to the main body. 
#840 & #840G:  Turn the bottom tubes (#93) as shown in drawing and slide them 
into the sleeve welded to the main body. 
ALL SIZES:  The correct position for each individual tractor will be determined 
when mounting the snowblower on the tractor.  These tubes are connected to the 
sleeves with a ¾” x 4 ¼” pin (#96) and a hair pin clip (#104).   
 
 
 2. 
#740:  Bolt the left (#20) and the right (#21) a-frames to the inside of the 
plates welded to the hitch tubes using 7/8” x 2 ½” hex bolts (#102) and 
lock nuts.  Join the top of the hitch arms by bolting a 1” o.d. x 2” spacer 
(#100) between the top plates using a ¾” x 4” bolt, lock washer and hex 
nut through the lower outside holes.  Bolt the upper hitch tube weldment 
(#47) between the same plates using the same size of bolt.  Use the 
inside holes on the top plates for the upper tube.  The other end of the top 
hitch tube bolts between the welded brackets on the top edge of the fan 
housing with the same hardware.  Tube must be turned as shown in 
drawing.  Tighten all hardware. 
#840 & #840G:  Turn the hitch weldment (#4) as shown in drawing.  Bolt 
the hitch to the two bottom tubes (#93) using 7/8” x 5” bolts (#103) and 
lock nuts.  The upper hitch tube (#80) bolts to the top of the hitch and the 
welded brackets on the top edge of the fan housing using ¾” x 4” bolts 
(#97), lock washers and hex nuts.  Tube must be turned as shown in 
drawing.  Tighten all hardware. 
 
 
 3. 
#740:  A category 1 top link pin (#18) is fitted in the top holes of the hitch 
arm plates.  This pin is used for standard three-point hitch only.  The 
bushing in the lower holes is used for the quick hitch. 
#840 & #840G:  The hitch fits standard category 1 and 2 three-point 
hitches as well as category 1 and 2 quick hitches.  The highest and lowest 
holes are for standard three-point only.  The inside set of holes must be 
used for a quick hitch.  Adaptor bushings are supplied to convert from 
category 1 or 2.

spout ring on the snowblower.  Lubricate the spout ring and clamps.
