If you're in Low, it shouldn't be running very fast (speed).  Low is for pulling/plowing and getting out of trouble.  Does it do the same thing in high gear?  Also,  what all do you have locked in when this happens? Is it in turf mode or are front and rear diff's locked in?

Umm, never new Gates to have a plant in China.  They did move some operations down to Mexico years ago though so maybe that's possible.   

Not much info to go on, but maybe not the identical part used in replacement?

I couldn't find this info in the manual for my 550 either.  Had to call CS to get the info over the phone.

Brand new? Take it right back to the store.

Most likely needs adjustment to the shifter or check/change fluid.

I use Lucas products , 80-90 HD Gear Oil for the diff and 10w40 Semi-Synthetic.  For the winch, some brands will cross over but not sure which.  Check your cooling system, seems to be the biggest problem with that model/year range (fan and coolant level).  Other than that, check wiring connections and water proof as much as you can,  corrosion causes a lot of issues as well.  

Different machine, but I kept it under 20mph until the first oil change.  For reference, speed was about 50% of top end.

Is this new or used?  If new,  probably shouldn't be at full throttle until the thru break-in period.

Should take 2 quarts.  Did you have the dipstick out or filter off when draining?   I would take out the drain plug again and make sure nothing is blocking it from draining (wear gloves for slivers.)  There was a thread on here recently where parts had broke loose.  If clean you can just refill with this oil.

How much oil did you end up getting out of it?  Or, how much oil did it take to fill back up?

7yrs old and 12 miles on it?  Sounds like there's something wrong with it and it's been parked for a loooong time.  Even if there wasn't, sitting for any length of time is not good.   There's quite a history of issues with those models on here. A good price would probably be one low enough to replace the engine.

Bought my 550 just about a year ago, no issues to date.  Most of the problems on here are from the earlier models that were Hisun machines, not from those that bought more recently when they switched to Linhai.

Bill, I installed another usb/battery meter in the open spot in the bottom left of your pic this weekend.  Took the front tire off for more room and used a flexible grab tool I had on the bench to pull wiring up to the battery.

Rent a skid steer with a mulcher attachment.  Looks like an oversized stump grinder.  We used them to clear out under power lines, which wasn't  done that often so trees would get to 6-8" in diameter and that thing would eat them up.  When you're done clearing just run it over the cleared ground and it's tilled and ready to plant.  

Another thought, I know the owner of a nearby off-road park and it's got some pretty tough terrain.  Last time I was out there he pulled up to talk with us, in his new  Honda.

Hisun makes them for Lowe's.... read through the Hisun and Massimo forum. Honestly i don't think their products, nor there after sale services are very good. I doubt Lowe's would be any help if you needed a warranty claim, or tech help.

I'd go with the Honda just for the fact of the unmatched reliable reputation they've built.

Just looked at the Lowes add for that, pretty much looks like an  MSU 500/700 that Hisun made for Massimo back then.  Take a good look at the badging on parts to see who it's actually made by, my guess is it's still Hisun.

Could you just attach one of these under the seat?

From your description, I'd say a UTV is what you'd want.  Much more comfortable than an ATV for extended use like plowing.  Plus you could have a windshield and enclosure.  No worries about being top-heavy,  nothing above shoulder level but roll cage and a plastic roof.   Plenty of options and prices ranges out there, if you can find them in stock.

There is a parts manual under the downloads tab for the 410.

Damn, guess I should have held on to mine longer.  Sold it for $2700, although it didn't have the rear seat. 

For something like that you might even be able to get by with an electric golf cart with a rear seat that folds down into a flatbed.  

Should be about half way up from where your drain plug is located.

Got one of those sitting on the shelf I've been meaning to install.   Wish I'd seen the  12v plug-in though.
