Dennis F - I hear you on owning a QL, or not wanting to own one. There were a few times when I uttered "gall dang-it" or something like that when putting mine back together. I haven't had my 109 or the 1650 side by side yet as they are in different locations, but the 1650 just seems to have a bigger/higher platform, but I would think they would be the same.
When working over the 1650, one of the things that I thought about when wrestling with the re-assembly is - that if this is done right, then I shouldn't have to revisit any of this for a long time. I put Dave Kirk's steering kit on, tightened-up the axle cradle, did the engine cradle mod and used very good IH original isolators (which I gather the cradle mod should help those last much longer), added a Dave K's muffler crutch and a new fan. So far, so good. For whatever reason (and again I need to compare the 109 side by side to the 1650) the 1650 just seems like a slightly bigger tractor, smoother riding and definitely quieter than any old iron tractor I've owned. It is also vibration free at full throttle at the operator's platform.
So I said all the above to say this - I think the QL tractors are solid and are a good bang for the buck - if one can get past some of the things like the engine isolators. My tractor has a 14 hp engine in it (got a 16 hp waiting on a rebuild), it pulls a moldboard plow like a dream, IMHO easy on the eyes and has hydro lift. We'll see this summer how it handles the 50 inch deck and long term how it holds-up. I still might try a RED 782 were the right deal show-up in my neck of the woods.
Jeff B - I think later QL's had 1 inch front spindles. That is a swap I'd like to make with mine just for kicks. The 4 gallon tank. My thoughts are that I kind of prefer a smaller tank as my mowing, while considerable, doesn't require that much gas. I passed on a commercial push mower one time for a consumer version of it in part because of the large gas tank. My thought with the push mower and with the 4 gal tank vs smaller is that I get more turn-over in my gas.
Vincent T - can't comment on your rotating snowblower chute, but that's a NICE looking QL!!!
Kraig - those wasp nests in your pic, when running that tractor in the summer, did you have duct tape over the creeper gear slot and vent hole? YIKES!!!!
Harry B - I know you had a 1450, but did you ever own and run a 1650? Just curious as to your thoughts on them and the 16 hp as a worker compared to your 169.
