OK , so here goes my dilemma; I have a 329/61 Grasshopper bought new in August 2018 that refuses to start when cold. It is not a choke/carb issue, the starter will not turn the engine over. I load tested the battery, (I have kept it charged also,) checked charging voltage etc, and the numbers are as follows; Cranking voltage when cold 9.8v lowest, with starter stalled. fluctuates between 10.6 and 11.5 when turning. Amperage when cranking; 409 highest reading when starter stalls, or initial engagement. 180 amps lowest when starter turning engine over. Battery load test results with SPX tester, 583cca. Now what happens here is when cold outside, usually mid 30's or colder, the starter will slowly, and I mean slowly turn the engine over, once the engine tries to fire after turning the engine over what sound like four or five audible compression strokes, the starter stalls. I release the key at that point, try to start, and soon as it makes one revolution, stalls again and repeat, and repeat, and repeat, again and again. The starter does not have enough torque to start this engine when cold. I tried using the battery out of my 2003 Silverado, which boasts 690cca vs the 540cca Grasshopper/Deka battery, and the same results. And to further check, the battery from my mower starts my cold truck just fine, but neither will start my mower. I changed from SAE30 oil to 10W30, with a slight improvement, but still not enough. So I reached out to B&S, which I found at that point that they must contract the same people that do telemarketing for their tech department, cause all they could do was recite the owners manual to me and nothing else. Then I got a hold of Grasshopper's tech department. They said that engine won't start in temps that cold without using some supplemental heat source. I told him that stinks, cause my Dad's little 126v61 starts up just fine, (which I have had to borrow it on several occasions cause mine would not start,) the Kawasaki FX801V sitting next to it starts fine, my old Turf Tiger with the Kawasaki FD series starts fine, and so-on. Is there anything such as a better starter available for this thing? Or any other trick? The supplemental heat idea to me is useless, you plug in a block heater at home, only to cool the thing right back off hauling it on an open trailer.
