Maintenance

Grease the bearings every 50 hours. Do not over grease. Usually one pump is

sufficient.

Check gearbox oil every 100 hours or seasonally, whichever comes first. If necessary,

add 80-90 weight gear oil. Oil level should be halfway up in gearbox.

The cutter teeth (KC180 serial # 1231-) have three shoulders. If a tooth becomes dull or

damaged, loosen the top nut, tap the tooth down, rotate the tooth a third of a turn, and

re-tighten the top nut. Cutter teeth can be sharpened with the proper equipment.

Sharpening carbide teeth requires a special process. See your authorized Ventrac

dealer for replacement parts or instructions on sharpening existing teeth. Teeth that

have lost more than 1/8” of original bite must be replaced.

Occasionally the (3) cutter head drive belts may need to be tightened. The following

procedure MUST be used in order to keep the cutter head and shaft in line with the

frame.

Shut off the tractor, apply the park brake, and remove the key.

Loosen the (4) nuts (A) on the bearings on either side of the cutter head. Loosen the

locking nut (C) on the back of the right adjustment plate. Loosen the locking nut (D)on

the front of the left adjustment plate.

Tighten the belts by tightening the nut (B) on the front of the right adjustment plate while

loosening the nut (E) on the back of the left adjustment plate accordingly. ALWAYS

adjust nuts (B & E) equally, so that the rotor shaft remains parallel to the gearbox shaft.

After the belts are tight, tighten locking nuts (C & D), then tighten the (4) bearing nuts

(A).
