On the older RTV's, there's an aux pump. When climbing, if it starts to bog down, let OFF the go-pedal to about the 1/2 way point. The aux pump will kick in and give you more power but you will lose some speed.
Do you have dash lights on that tractor?
IIRC, the fuse for the headlights is the same as the dash lights. If you've lost both, fuse or loose wire, probably right behind that fuse at the block.
I have notes about this but not with me. It was from a 770.
Check the fuse first. Also could be loose wire at the back of the fuse box going to that fuse.
I think that's what I have on mine.
Have you considered the glue on or magnetic heaters? I use the glue-on versions on my RTV. One on the engine, one on the tranny.
Bump. Heard y'all talking so much about ATO that I was going to look them up for some ATV tires.
Since they're no longer in business, who do you go with?
Sorry, I don't know of any free ones.
AGCO seems to offer them for a reasonable price.

This is for a Mahindra but I can't confirm it's for a 5010.
It looks like a dipstick is built into the oil fill cap.
The 2 dark lines at the bottom of the plug may indicate your high and low fill levels.
