Locking Diff

Thanks for the info. I think I might try this on my Missimo 410

Thanks everybody, I emailed Massimo company about the oil filter. They replied and said would have technician mail me. The technetium must have forgot? I bought a oil extractor like somebody suggested. It kinda works, I couldn't get but a little less than a Quart of break-in oil out. So I just added enough to fill it. I figure if there is no oil filter what's the difference?  

Where is the oil filter on a Massimo T-Boss 410? Also oil drain is soooooo tight I can't get it loose, any suggestions?

  They have told me that the rear differential is always locked and it's the front one that locks when put in 4wd. It sure makes it hard to turn on wet grass, gravel or concrete.  Not a good design, you have to give plenty of gas to get it to go while turning  going slow. Other than that it seems like a well constructed unit,, it does what I need. It could use power point to plug in my sprayer.

Just got off of the phone with guy from the factory and he said that it's always locked. That just can't be right. The big boss wasn't there today but I have his Ph# 972-893-3180 his name is David Stontz?. I'll try to call him tomorrow and let you know what he says.

It's been nasty weather and I haven't had it out. So I don't know if it's still locked or not? Thanks, I'll let you know in a few days.

Thanks, I'll see if it is still locked.

I just purchased a new 2019 Massimo T-Boss 410 March 2020. I haven't figured out how to unlock the differential?  There isn't a switch?
