Kubota L4701, Land Pride RB3784 Rear Blade, Bearcat SC5540 Chipper Shredder
I only have 130 something hours on my L4701 and have had five regens. 20.7 hrs, 50.3 hrs, 72.9 hrs, 87.5 hrs and 105.2. I don't feel a deference but I'm usually not working very hard. Two of those regions I was already done doing what I was working on getting ready to put the tractor away. They have all lasted about 10 minutes.
I'm just about the same with a M62 my regens have been around 45 75 & 105hrs. Although the times seem to be getting closer together, it's winter time & I'm not bushhogging. Regen's take about 10 mins. maybe less, they're loud as **** & I have to lift the FEL because the blow-torch exhaust is aimed at my left cylinder. I choose not to work while it's regenerating so I simply roll forwards & backwards like I'm an idiot. this is because any load placed on the tractor sounds like to much strain for it. Once it's complete, I run it for at ~5 minutes to cool before shutting it down or just go back to work on it.

I'm not sure what everyone else's take is on this & for now, I'm fine with it. I'm betting that by the time my tractor has problems with the regeneration, DPF, or anything with these emissions, we will either be thanking ourselves for not contributing anymore pollution than we already have & a bunch of Chinese guys will be complaining in China on tractor forums about DPF's & regeneration like we are right now. If NOT, then I see no point in continuing down this tree-hugger's yellow brick road...
It's a lot like trying to talk to someone about cattle, they get soo pissy & say I cruel to animals then 5 minutes later they're hungry for a cheeseburger or steak...
