Hi, 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. Armin 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.
