These helpful tid-bits are what user forums like this are good for Max! Rich clay soil is what we are known for even though most of my drier season dust is grass chaff, the nearby agricultural paddocks can produce fair bit of clay dust at times. Will keep close eye out for such problem with...

SirMaxwell, Was near end of heavy mowing season and with what I had done, the machine finished up with no real overheating issues. I did discover the (not original) water pump had a leaky seal, so replaced it.... a tight squeeze but no drama.... but sure it was not causing the hot-running. No...

Sounds interesting.... may help the clogging situation if reverse-flow ONLY done briefly where dust/chaff can not be pulled into the open (and unscreened) engine bay. My air filters tend to choke up under same conditions that clog the rad screens, so I pull them and knock/blow dust from them...

Yes, I learned early on to keep close eye on the rad screen and blow it and the rad itself clear often especially in dry conditions. Did a full cooling system 'flush' while back, but looked good before and after. Also rigged up a rubber flap discharge chute to divert the grass further from...

PTO output on F-3680 is smaller spline shaft than 'standard rear PTO on other Utility, CUT or SCUT tractors of any make I know of and is used across many models and years of Kubota F, Z and other mowers. It may well be same as under-belly PTO used for some shaft-drive mid-mount mower decks and...

I think most mid-mount rotary CUT or Utility mower deck PTOs run at similar speeds.

Hello Rocks, It is similar but Not the same! The F lift system is basically a 3pt (mounted bit lower to ground) without the top link. I have set up several custom attachments to use just the lift arms & pins (cat 1) with the rear arm mounts so lifts at same angle and arc as the arms move...

If you get the F-3680 I would just mow over it several times at good height to chop it into finer bits and leave it where is. (Always mow at full throttle.) The F machines are industrial-rugged, but not so easy to change cutting height often. (do not need tools, just fiddly!) I settled on...

So long as any stumps are ground down to near ground level and no significant rocks, either of my F-Series would handle that easily with Kubota deck at about 4" and turf tires.... even without my loaded tires, 3" wheel spacers, etc. The Kubota blades are mounted to spindles with cupped...

G'Day.... Can understand some of your dilemma.... I got my PT-1845 and F-series used and the price was right.... they are way too $$$$ for personal use IMO. The PT was built like a tank, 45 HP Deutz engine plenty of power and durable like Kubota. Very stable with minimal ground clearance but...

If you still debating on suitable machine, I have both a F-2880 w/60" deck and 3680 w/72" deck on our 4 acre VERY steep property for last 11 years. The property was very overgrown (heavy grass, not woody brush) when we bought it but was able to fully clear with the stock 60" Kubota deck...

Thanks JWR.... my next step is to use a cooling system flush product to better clean the insides and see what it does. As I said, not actually overheating at this point, just noticeably running hotter than used to and my other nearly identical 1105 engine. Will check out new rad cost just in...

Thanks again Rodger.... no smoke or power loss, so will concentrate on cooling system some more. Cheers, Rip

Thanks for the diesel details Rodger.... I knew was not same as for a gas engine, but the service manual does mention injector timing as potential issue for overheating. I guess individual injector problem would be more of a power issue (not in my case). After giving the cooling system bit...

Belt is tight and in good condition (is also a real pain to change!)
