MAINTENANCE
BLADE SPINDLE and BELT TENSION IDLER ARM
LUBRICATION & MAINTENANCE
The area beneath the shielding must be cleaned of debris such as grass clippings and twigs to prevent buildup, causing
friction on belt and pulleys. Clean any lubricant accumulation occuring during the lubrication procedures.
Check drive pulleys and idler pulleys for excessive wear or damage. Replace if needed.
Check Belt Tensioner Idler Arm for excessive wear / looseness and freedom of movement.
Blade spindles (Figure 5-4) must be greased with 5 shots of grease every 10 hrs. Access lubrication fittings through
holes in top of the shielding above the Spindle Assembly. Occasionally grease the spindle until a small amount of
grease purges from the relief hole (Figure 5-5), located at the base of the spindle housing under the sheave. The
shielding will need to be removed in order to see the relief hole. Clean off any excess grease. The Belt Tension Idler
Arm should be greased each time the blade spindles are greased with 3 shots of grease.
NOTE: Do not over lube as excess grease may get on belt drive and cause belt slippage.
