I purchased this tractor in the spring , the previous owner replaced the muffler with a straight pipe , which has cracked and needs replaced , the stock muffleris no longer available , the only one I've seen is used and the price is on the high side . so I've beeen looking at mufflers that fit other tractors , given that the stock TG1860 muffler had a long tail pipe going down , and the tail pipes on the others that I'm looking at go foward through the grill , I'm thinking that I can use one of these and rotate the muffler so the tail pipe points down and put an extension on it . the mufflers I've looked at range in price from $40 to $120 , part #s 2551-83110 , 2561 - 83110 , 2571-83110 and 2581- 83110 , they all take the same gasket and looking at measurements are very similar in size , guessing the difference being the position of the tail pipe . I'm open to suggestions and finding something that will work for this tractor other then having a new straight pipe made ,
