Hi Guy's. My thoughts have always been this, the 318 was way over-engineered for what 90% of the people used it for, just cutting grass and possibly putting a front blade or snowthrower on for snow duty. In that respect, the later 345 style of tractor is good for things such as that, but no more. The 318 could have a loader & 3pt hitch to do serious ground engaging, which the 345 does not have nearly a strong enough frame for. So, in my opinion, when JD came out with the 345, they just made a tractor more in tune with it's actual use. Now, do us "tractor" guys like the fact they down engineered it? No, but it probably made economic sense to JD. Even though I wasn't "into" L&G back then, I know I was quite dissappointed when I saw the first 345 and saw the downshaft engine, belt drive hydro, stamped frame, no loader/3pt option, etc.
