I read through a few related posts but my symptoms sound different.
Have an '89-'90? Wheelhorse 520-H, model 4120OE01.
When I engage the PTO, the engine stalls. No fault indicators.
However, everything else seems normal:
- all lights work when pressing 'TEST'
- when I engage the PTO without sitting on the seat, the engine also stalls, but the 'SEAT' light comes on. Normal.
- when I try to start the engine with the PTO engaged, it won't start and 'PTO' lights up. Normal.
- after disconnecting the load (2-stage snow blower belt in this case) from the PTO, I get the same problem, engine stalls immediately. PTO pulley turns along fine with the remaining motion.
And I also need to mention: the first time it happened it was intermittent. The tractor and snowblower attachment were used over a month ago, without any problem.This time got above symptom upon startup. I didn't feel like shoveling so after revving the engine for a minute or two and a few 'encouraging' words, it worked. I switched the PTO off and on several times afterwards with no problem (engine warm, obviously). Today, with the engine cold, the problem is back.
I think there's enough reason to rule out the PTO- and seat- switches. But what else should I check?
This is my first time writing in the forum and I hope I've given enough clues without boring you.
Any hints and advice are appreciated.
PS any good tricks to counteract the belt tensioner on the 2-stage snow thrower (model 79361)? It is a bear to connect and disconnect.
I'm looking for a oil pressure sensor for a 520-8 at least that's what I was told it was but it might not be that so if someone know what part it is that would be great as I'm still learning I cant seem to find one anywhere if anyone has a extra one or knows were I can get one the info would be greatly appreciated thanks
Started fine 2 weeks ago. I left key in ignition and fear grandson may have turned it slightly to right a week ago.. not enough to engage starter but perhaps enough to drain battery.
Went to start it yesterday and no charge at all. Started charging it and battery began to take charge. However starter turned over but didnt turn engine over.
Question is do I just need more of a charge (more amps) or do I have another problem?
Lol, have 5 inches of snow headed here starting tonight so I need to get ahead of this today.
I picked up a wheel horse and I am having trouble finding the connection for this wire. I have no spark and have searched for the placement of this wire within the distance of its length...any ideas?...can't seem to paste the picture....
i just traded my way into a 520-8, and am looking for some info on its value. This is my first Wheelhorse- I had been looking for an older one in the style of a c161 hydro or d180 but ended up with this- has the 48” side discharge deck. I’m wondering if I’ve any chance of trading it for an older hydro with 48” mower and snowblower or if I should just bite the bullet and list it for sale... and for how much. Or if I could find a snowblower for this one. It runs and mows great, but is a little big for the 48” deck. Any info would be appreciated.
