Adjustment Continued...
2-8 Exhaust Deflector Installation
To adjust the belt tension, turn the belt tension
adjustment bolt clockwise until there is 1” of deflection
with 10-11 pounds of pressure applied to the center of
the kevlar belt. When the belt has the proper tension,
tighten the (4) 5/16”-18 x 3/4” HHCS P#(K1153) from
Figure 2-7b and 2-7c that secure the gearbox to the PTO
assembly. Replace the belt guard and (3) 1/4”-20 x ½”
HHSTS P#(K0353).
(All units where the muffler deflects out the left
hand side of the tractor will not require an exhaust
deflector, or removal of existing exhaust deflector.)
Remove any existing exhaust deflector and hardware
from the muffler. Attach the exhaust deflector P#(J0282)
to the muffler and fasten with the exhaust clamp
P#(X1064). Rotate the exhaust deflector downward
before tightening the exhaust clamp, as shown in Figure
2-8. This will prevent the exhaust from damaging the
collection bags.
For the Briggs and Stratton
18.5HP engine, simply remove the existing exhaust
diverter. For any engines with the exhaust on the left
side of the engine, the exhaust deflector is not required.

Assembly Installation
Lift the top assembly P#(A1028) into position as shown
in Figure 2-10. Fasten the top assembly to the upper
frame assembly using (2) 5/16”-18 x 2-1/2” tap bolt
P#(K0125), (2) 1/4” flat washer P#(K0037), and (2) 5/16”
nyloc nut P#(K1180). When fastening, leave the nyloc
nuts slightly loose so that the top assembly can pivot
freely.
