JeffP 0 #1 Posted March 13, 2011 This worked fine until parked for the winter. Now it will start fine but not move. The pulley seems to turning. This is a uni-drive hydro unit. I could use a service\repair manual also. Thanks Share this post Link to post Share on other sites

Kelly 1,029 #7 Posted March 13, 2011 First off how long did you let it warm up?? I have a few 520's and most of them in the cold take at least 5 min. before they will move, I have one if it sets for a few weeks it takes 10 min at half throttle before it will move in the cold, does the deck lift?? look under it for puddles of oil, check the oil level, dip stick under the seat.

ChevelleSSLS6 0 #14 Posted March 15, 2011 check the level of fluid as well... especially if it leaks (like mine does). about the Canadian WH. :thumbs: Share this post Link to post Share on other sites
JeffP 0 #15 Posted March 19, 2011 Update--The deck hydraulics would not work either so following Kelly's advice I let it warm up for about ten minutes and tried again..the direction control did nothing so I tried the deck and after about 5 tries the deck started working, then the mower started moving also..slow at first..but the motor started sounding like it was under a heavy load and sounded like it was choking out. my first thought was the hydro pump so I lifted the disengagement lever, but the motor still sounded like it was choking out so this told me it wasn't the hydro unit. I then did a basic tune up and changed fuel filter, air filter and plugs. I also bought a new battery since the present one was three years old and didn't hold charge very well. This fixed the motor issue and the hydraulics are working ok also. Thanks for all the help. Jeff Share this post Link to post Share on other sites
Kelly 1,029 #16 Posted March 19, 2011 Glad you have it figured out, I love my 520's, I'm going to change my trans fluid to full synthetic oil, I hope that will help next winter with the warm up time. Share this post Link to post Share on other sites
can whlvr 993 #17 Posted March 19, 2011 glad u got her working without any grief,its funny how long those eatons take to warm up,my friend around the corner has one and all it does is snow blow,the deck rotted out and he bought a homedepot jd to mow with,anyway he starts it in the winter and then goes to have a coffee before its warm enough,i have a 1975 c160auto that i had the pump professionally rebuilt and it will lift the blower instantly even in the VERY cold(i dont do this as i let it warm up but it will move instatly in any temperature,strange how different things can be Share this post Link to post Share on other sites
tiggercl 28 #18 Posted December 6, 2011 Glad you have it figured out, I love my 520's, I'm going to change my trans fluid to full synthetic oil, I hope that will help next winter with the warm up time. Is it best to warm up the hydro on the 520 with the brake on or off? Share this post Link to post Share on other sites
Kelly 1,029 #19 Posted December 6, 2011 If your tractor has the pull up handle for the belt tensioner,(many newer ones like my 520's don't have it) start the tractor let the engine warm for a min. or so, then release the brake/put tension on the belt, that will turn the hydro pump and let the trans warm up, be sure to block the tires if your tractor creeps, my 520 does not creep but in the winter for safty I put the plow all the way down as a parking brake, so I don't have any issues with it running off or over me.

Forest Road 594 #20 Posted December 6, 2011 I started running amsoil in my 314H last year. The trans is definitely better off in the winter. I still let it warm up. Now there's less concern of thick gooey oil having to heat up on those sub zero days. I really noticed a difference in my cars on cold starts with amsoil compared to conventional oils.
