Thanks for all the info everyone. I just went and looked at a really well maintained and lowish hours
L4150 not too far away from me, for a pretty fair price I think. Has a 2-way tilt 8' snowplow blade on the front, which I would want to remove and possibly try to sell, but the good thing is that it has a 2-lever valve waiting out of the way on the fender if I ever decided to mount a FEL on it. Currently I don't want a FEL since I have a skidsteer to do material moving.
Everything I've been reading about
L4150 applauds it for being a really solid and reliable time-tested model.
I forced myself to not take any cash with me so that I will have to chew on the decision to buy it for a few days before pulling the trigger.
This thing seems to have everything (and actually a little more with the 540/750 pto switch) that the M5660 that I am considering brand new has, except for the hydraulic shuttle shift (wet clutch would be nice but the 4140 had a new clutch installed just 500 hours ago), folding ROPS, and the constant rpm management feature. And of course the DPF, which I'd sort of lean towards if it wasn't linked to a computer. The
L4150 started up clean as a whistle though, I couldn't even smell the diesel while running it for 20 minutes.
Any last thoughts before I make the move?
