Mikecetj 10 #1 Posted August 29, 2020 So, have a 1982 sk486, just got.... serial 01-16kh01-24458. Under that is 2054. It has the original (not butchered) rear discharge under belly mower. I am having a tough time deciding on blades, finding the tensioner pulley, and the belt for it.... any help? Pics for the fans 4 1 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,498 #4 Posted August 29, 2020 Welcome to the forum. Can you read the mower ID plate? Garry 1 Share this post Link to post Share on other sites
Mikecetj 10 #5 Posted August 29, 2020 The tractor one, yes. The mower deck, no Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,498 #6 Posted August 30, 2020 Just a guess. I can't tell the width of cut either. When I know what that is will give you a list of all the possibilities. Garry 2 Share this post Link to post Share on other sites
Mikecetj 10 #7 Posted August 30, 2020 I would have to say 36".... the deck total width is 40"... the blades are 2 x 12" and 1 x 14" 1 Share this post Link to post Share on other sites

Mikecetj 10 #9 Posted October 18, 2020 It is the 05-36mr01. Got the blades and pulley right on the first try. The motor to deck belt is too long, and the deck belt is too long. Any ideas for part numbers? Share this post Link to post Share on other sites
peter lena 8,067 #10 Posted October 18, 2020 MIKECEtj, definitely that is a / 36 r/d deck , that blade actually looks not too bad , a small fine flat file will probably bring it right back ,with out removing too much metal , also scrap down the underside and lubricate it with waste oil , to kill off the grunge and stop rot. also soak down those blade nuts with penetrant oil. others will have those belt numbers Share this post Link to post Share on other sites

bo dawg 477 #12 Posted October 19, 2020 Originally the SK486 would have came with a 48" deck. Should be what the 48 in the model number means 1 Share this post Link to post Share on other sites
