swisstrac 49 #1 Posted August 14, 2017 can some one tell me what the primary choice size mower is for the 520H?? i am looking at one and it has only a 42" seems a bit small for a 20hp tractor/ thanks much for your input/Ray Share this post Link to post Share on other sites
WHX?? 48,776 #2 Posted August 14, 2017 My choice is a 48 but I don't have a great deal to mow. 42 is a bit small considering they can take up to a 60 if you have a large yard but the 42 would make for a nice cut in short order for a medium yard. 1 Share this post Link to post Share on other sites
Sparky-(Admin) 21,300 #3 Posted August 14, 2017 I suppose it all depends on the size of the lawn to be mowed, the obstacles that need to be mowed around and also what size deck will fit thru your shed door. My shed will only accept a 42" deck for instance so if I owned a 520 it would be spinning a 42"er. Mike.... 2 Share this post Link to post Share on other sites

In addition to shed doors - gates in fences tend to limit your size as well... 2 1 Share this post Link to post Share on other sites
Aldon 4,826 #5 Posted August 14, 2017 60 that could come with them are extremely heavy. And the weight along with the additional torque on the frame can cause issues. But they provide a nice cut I'm told. IMO the 48" deck is the best overall compromise for speed and flexibility. 2 1 Share this post Link to post Share on other sites
WHX?? 48,776 #6 Posted August 14, 2017 Some correct me if I'm wrong but wasn't a 48 the dealer recommended deck? 1 Share this post Link to post Share on other sites
WVHillbilly520H 10,373 #7 Posted August 14, 2017 Most around my area seem to be 520s with 48" decks even the 523Dxi I got last year had a 48" deck hung under it vs the big 60" but with the 42" I doubt it runs out of power in tall grass, Jeff. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,032 #8 Posted August 14, 2017 I believe the rear wheels on the 42" deck interfere with the rear wheels/tires used on the 520. Garry 2 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,032 #10 Posted August 14, 2017 Yes they did list a 42" SD deck. Probably not recommended because you don't need 20hp to run one.

Chevydave 25 #11 Posted August 17, 2017 Looks like the deck height adjustment wheels might be further apart on the rear discharge deck, 520 wheels on the rear of my 416-8 with a 42SD didn't work. Share this post Link to post Share on other sites
cleat 5,809 #12 Posted August 17, 2017 42" SD deck will only fit the early maroon 520's with the smaller tires. Later 520's and 520HC with the larger tires hit the deck wheels. I know for a fact because I tried. Cleat Share this post Link to post Share on other sites

I had to move the bracket for the mower deck wheels out about 2 1/2" Edited August 18, 2017 by 608KEB Share this post Link to post Share on other sites
