Tinys 25 #1 Posted August 29, 2016 (edited) Need some help identifying my deck model number. It's on an 88 520h. Was told it's a 48 but ordering some parts today and found out its a 42. Should've pulled the tape earlier. 05 48sc01 is what I was told but that's wrong. Has 2 belt covers the blade drive belt is 85" and the idler pulley is 3.75 " outside diameter. The belt for the 48 was 89" I think. Too long so we measured the old one at the parts counter and got 85. The new idler pulley for the 48 is 3.25". I'll go out in a few and get some pics of the deck. Thanks Tom Edited August 29, 2016 by Tinys Adding pictures Share this post Link to post Share on other sites
Bert 760 #2 Posted August 29, 2016 Your right, that's a 42 inch deck. I can't help with a number but the renforcment rod welded around the outside bottom edge tells me that its correct time frame for your 88 520. That may help you or ordering parts 1 Share this post Link to post Share on other sites

daveoman1966 3,745 #4 Posted August 30, 2016 (edited) 42" SIDE DISCH DECKS: the SPINDLE bel is # OEM 6738 at 86" long. The MULE DRIVE belt is OEM #102742 (or 94-2501) at 103" length. On-line for $19 and $22 respectively. OEM belts are far superior to the after-market brands...IMHO. Edited August 30, 2016 by daveoman1966 1 Share this post Link to post Share on other sites
Tinys 25 #5 Posted August 31, 2016 Thank you all for the help. I'll get more time this weekend to work on it again.

gwest_ca-(File Mod) 11,032 #6 Posted August 31, 2016 I went to the attachment list for your tractor/year and found the 05-42MS05 was the deck for 1988. I just knew the deck models following this one would be the same as far as connecting to your tractor. The 1989 model was 15-42SC01 and after that there are no 42" SD decks listed for the 520. Here is the 1988 attachment list The D&A is the Details and Attachment list. This info originally came from here Garry 1 Share this post Link to post Share on other sites
