Got a technical question for you guys. Our Z-Master 52" Kohler 20hp was stalling this morning every time I would try to engage the PTO. Ran fine otherwise. It was cold and raining this morning (-6C) so I thought at first that maybe the engine needed to warm up. Nope. I let it idle at full throttle for 15 minutes at one house and still the engine killed when I tried to engage the blades. <p>Took it to our service guy and he checked the fuel delivery and the oil (it's got a low oil pressure engine kill switch) and the spark and found no problems. He replaced one of the two 20amp fuses and then miraculously the blades started to engage. Fuse wasn't blown either. <p>So we left and when I got to the next house where I could use the "Z" I tried to engage the blades. The first two times the engine stalled, third time lucky. Didn't use it the rest of the afternoon.<p>Any ideas? It's a new problem to our service guy so he's as perplexed as we are.<p>----------<br>Dave in S.Ontario<br>www.cutntrim.com
