do you guys use for the cutter housings on your walk behind mowers? I have a Bunton 48 and the manual tells me to use Cheveron SRI-2 Bearing grease instead of the NLGI #2 lithium base EP grease. I can't find the Cheveron grease anywhere and was wondering if there was an equal replacement. Gotta keep up maintanance. If you don't take care of the machine, it won't take care of you. Thanks in advance for the replies.
