BLADE BAR INSTALLATION PROCEDURE
FOR THE
BROWN TREE CUTTER
INITIAL BLADE BAR INSTALLATION
NOTE: Prior to blade bar installation, ensure that the output shaft and the hub are clean and dry.
Apply anti-seize compound to the hub or shaft.
Step 1 - Remove the bolts from the A-frame braces at the A-frame and lower the braces to the cutter
deck.
Step 2 - Loosen, but do not remove the A-frame attaching bolts and lower the A-frame down against
the input shaft.
Step 3 - Using a suitable lift, turn the cutter upside down, being careful not to damage the gear box.
The cutter should rest on the tailwheel assembly and the A-frame mounting plates.
Step 4 - Be sure that the output shaft is clean, coat splines with copper antiseize. Be sure the splines
of the hub in the blade bar are clean.
Step 5 - Carefully take the cutter bar and position it over the splined output shaft making sure the
splines are aligned. The bar should go down approximately 2 3/4” on the shaft.
Step 6 - Install the nut on the output shaft and tighten to approximately 300 lb-ft with a 2 9/16”
socket part number T5-054AS.
Step 7 - Take an 8 to 12 lb. sledge hammer and hit the bottom of the cutter bar several times,
approximately 6 inches from the hub, in a circular pattern around the hub.
Step 8 - Tighten the bar again to approximately 2200 lb-ft.
Step 9 - Repeat Step 6, hitting the bar with hammer.
Step 10 Retighten the nut to approximately 2200 lb-ft torque. Remove the wrench for the nut and
check the location of the cotter pin slot and the hole in the shaft. If the hole and slot are
not aligned, continue tightening the nut until the hole and slot are aligned and insert the
cotter pin. If after tightening the nut to a maximum if 3800 lb-ft of torque the hole and slot
are still not aligned, install a different nut and repeat the tightening procedure. Never loosen
the nut to align for cotter pin installation.
