the manual say very little on breaking in the unit, all i've been doing up to date is keep the block heater on it to aid during cold startups and letting it warm up before any higher rpm usage. I've also checked all fluid levels before every time its been started and used. It's only got 3.7 hours on it right now so its still brand spanking new. Any suggestions would be great.

I like to vary the rpms for the first couple hours and then WOT throttle to seat things in there. Your not going to hurt it and run breakin oil for the 1st 100 hours and change it @ 50 hours. slkpk

That's good advice -- try to vary rpm. In other words, after you've warmed it up, don't just park the throttle at pto rpm. Instead, try to operate it at various speeds ranging from say 2000-3000 rpm, for periods of 5-10 minutes at a time.

I would do this as much as possible while the break in oil is still in there. But there are going to be times when you need full pto rpm (snowblowing, lawn mowing, etc.) Just try to get by with lower rpm settings while you're transporting, or using the FEL/BH, etc.

P.S. How do you like your Minimax engine so far?

good advise. I love the engine so far, plenty of guts. Minimax? the engine is a Yanmar on mine.

Sorry for the shorthand. Your tractor has the 0.9 liter Yanmar 3TNM72 "Minimax" engine. It's a fairly new Yanmar offering so there isn't a lot of experience/feedback with it yet. If you'd like to know more about your engine, we had a long discussion about it when JD decided to use it in the X700 series.

ahh, got it. well after reading the discussions, seems like i'll be a ginny pig!
Like i said before, the engine in this SCUT has more guts that anything i thign i can throw at it, more power than that will probably be a waste as it won't be put to use, however i do hope that it proves to be as tough as the 3TMV76. :dunno:
