LOL Marne. I sold the 252 with the Vanguard a couple years ago, whole machine was getting old and worn. I was actually disappointed in the longevity of the Vanguard, only had about 1400 hours on that engine and it was using gobs of oil.
Bought a 292 when they came out in Nov 2013, about 3 months before they came out with the 362, argh. Salesman swears he didn't know they were coming out with the 362 when I bought the 292, whatever. So I've got the 29hp Kohler (now they call it a 26.5 under new power rating rules).
Anyway, got about 1000 hours on it so far, so just looking to the future on the engine upgrade. The 292 has the same drive train as the 362, which is a major upgrade from the 252. 1-3/4" cutter wheel bearings that are now double roller bearings, the jackshaft belts are one size up from the 252 as well. Cutter wheel belt is way wider than the 252. I do think the clutch on the 362 is different, probably a bit beefier, but hey, if a 252 clutch can use the power of a 35hp Vanguard with no issues, than the 292 clutch should be ok when the days comes. Or it may be time to just upgrade to the 362 clutch at the time of a new engine. The machines are twins except the 362 has the 4 wheel stance, I've got the tricycle, which is fine for me.
Fwiw, I got 900 hours on the cutter wheel bearings, about double what I used to get on the 252.
Maybe Kohler will come out with a horizontal shaft 37-40 hp EFI engine by time I need one. They have the vertical out now. The 292 came with the EFI Kohler, no issues with it so far. And the Kohler 25 on my first 252 went 4300 hours with no issues, I kinda like Kohler so far. Demo'd the new SC40TX a few weeks ago with the 40hp Kohler diesel, was good, but feel alot of hp was going to running the hydraulic motor on the cutting wheel. If they'd just put that engine in a 292 or 362 frame....
