Diesel - worth more or less

[UCD 15]

Depends on weather you want to buy it. If you were buying it $1500 would be a very good price. If I was selling it I would want at least double that if not more especialy with the attachments with it. Parts for the tractor are easy to find from any dealer. The engine which is a Lombardini 18 1/2hp 790 cc 2 cyl air cooled diesel made in Italy is another story parts are expensive but can be found. These engines are used in portable refrig. units on trucks. The only part i can't find is a muffler for mine as it was special made for briggs who sold the engines to Simplicity at the time. This & $1.00 might get you a small coffee Maynard aka/UCD

I need you're help. A friend of mine is selling a family members estate and it turns out they have a Simplicity Diesel 18 hp 1985 with snowblower and cab and deck. From what I can see on Simpletractors this would be a 7790? I am trying to help her determine the value of this tractor. I haven't seen many posts about diesels, so I'm not sure what the general consenses is about them and their value. Are they harder to get parts for? Ultimately what do you see as the value of this tractor. 1000, 1500, more less, any input would be greatly appreciated. It will probably come up for sale in May or June. Thanks for your help Joel

UCD: Can you do Brad W.'s "stackjob" muffler? It would undoubtedly be much cheaper. BTW, Brad: did your stack make it quieter, and if so, is it significantly quieter than stock, on a Model "800" like we, and Brent, and Woody, and others, have? And re: your question, Brad, on why so many 8hp. repowers, I'm beginning to think that B&S must have discontinued the 7hp after the '60's. Anybody know? My 20 cu.in. 8hp. is a 1970, I believe.

Peter, I tried Brad's stack muffler setup on my 916H last year. Used a farmall cub muffler from Farm and fleet. The sound is alot different but not any quieter that I could tell. Also I had a real hard time mounting it out of the way of everything. Someday, when I get $100 just to "blow" I'm gonna try one of those super-trapp silencers you add on to your exhaust system.

BigSix A muffler is no problem i can make one out of 4"well caseing that will never burn out. I was looking for an orignal one some where out there some one has got a good used one. Super trapps are nice as you can tune them i used to sell them in my speed shop but they don't have a tractor look. the diesel sounds REAL "MEAN" with no muffler.

UCD - I don't really care about the tractor look on my mowing machines. I'd just like them to be quieter. I know this has been discussed many times on this site, but I have not found a good solution to the loudness of these machines. Do Super-Trapp silencers really work as advertised? Thanks, Brent

Brent I don't like that loud noise all the time either. Just one of my wise cracks. Yes they do Hp.is controled by the way an engine breathes. In order to get fuel and air in you have to get exhust out. A restricted exhust system is quieter but restricts the exhust flow, by being able to add defusers to a supper trapp system you can increase flow and decrease noise. The right exhust system can add 30 to 50 hp on some engines not a garden tractor engine of course maybe 1 or 2 hp. Thier are some electronic mufflers in the works that cancel out sound waves so you can hardly hear the motor running. The bigger the muffler with more baffles = quieter exhust.

UCD, Thanks for the input on the tractor value. I will relay the info to the family. Joel
