Accessories & Optional Equipment

Certain accessories and optional equipment may or may not be available in all 
countries, depending on varying circumstances. The following key symbols help to 
explain what is sold as standard and what is optional equipment, or may not be 
available on the 

McHale 991B

. They are only correct at the time of print and may vary.

12.1  Side Tip Damper 

The side tip option is used for knocking the bale onto it’s side and is very useful for 
coarse ground with strong stubble (which may have a tendency to puncture the film), 
as it allows the bale to land on it’s edge, which has a much higher degree of film 
coverage. It is also very useful on hilly/sloping ground as it can prevent bales from 
rolling, when they land on their side.

12.2  500 mm Dispenser Kit 

A 500 mm wide conversion kit allows you to use 500 mm wide plastic film, instead of 
the standard 750 mm. The kit includes a sprocket, extra length of chain and a plastic 
pipe to hold the film roll.

12.3  Remote control kit for static machine 
operation (991 BER) 

The remote control kit is used for static wrapping. The kit includes a radio receiver and 
remote. See “Radio Remote” on page 53 for more details.
