stevebo-(Moderator) 8,040 #2 Posted November 16, 2014 The 20hp Onan is a twin. That is the motor in ALL 520's and 520 HC tractors. Share this post Link to post Share on other sites

ericj 1,576 #7 Posted November 17, 2014 if it was done right and not butchered and runs good it would still be a nice find if the price was right eric j Share this post Link to post Share on other sites
Jrblanke 840 #8 Posted November 17, 2014 (edited) I feel like I saw that one for sale earlier this year on craigslist up in your area. Does it have a 60 inch deck? For some reason I remember a 520 for sale with a 20hp kohler and a 60 inch deck. I want to say it was in Bedford, VA.

312hoss 0 #9 Posted November 17, 2014 Hi RS members, can someone tell me the difference between the 520-H and the 520-HC? Share this post Link to post Share on other sites
ericj 1,576 #10 Posted November 17, 2014 the 520-H was made between 90 and 97 and had toro decals on it. the 520-HC was made in 89 possible late 88, the HC had the forward swept axle and only 3 gauges in the dash and the 520-H had 5 gauges. the C stood for commercial . the HC has more ground speed than the 520-H the 91 and newer tractors have the gear reduction steering. the controls were also different locations also. the 88 & 89 520 had the controls down on the center console and the hydro lift was on the left side of the dash tower, the 90 and newer had the controls up under the steering wheel. you should be able to do a search on here and find pictures of all of the different models of the 520 on here i have some pictures of the 90 and newer in the what are you using for snow clearing thread. i think its on page 10 eric j 1 Share this post Link to post Share on other sites

ericj 1,576 #13 Posted November 17, 2014 i would have mentioned the chrome but he said the onan motor was swapped out for a kohler, so i figured the point was mute. but i've seen more than 1 tractor listed on c/l and the sell said it was a kohler when it was actually an onan eric j Share this post Link to post Share on other sites

The 520H was made from 1988 to 1997. The 520HC where made in 88 and 89 in addition to the standard 520H. Share this post Link to post Share on other sites
