Thanks Scott, I was/am hoping that is all it is. I got the tractor out last night for @ an hour and used it and had no problems. I've never owned a small compact before. The smallest thing I've ever owned was an old WD45. When I changed the antifreeze in it (WD45) I don't remember ever having any overflow comming out of the overflow tube. Just didn't want to do something to ruin my investment. When checking the manual for the Mahindra it just says to top off the coolant after running. I know on the newer cars/trucks, their is a special way you have to put in the antifreeze to prevent the "air bubbles" and I didn't know if these new compacts were the same or not. Also being your a Mahindra guy, do these things run noisy at idle. This one seems noisy (think detroit) at idle but seems to quiet down at higher RPM. I'm only compairing to Kobota and New Holland being that I have only ran those two compacts and compairing it to Mahindra. The fellow I purchased it from said it always ran that way. The unit runs great, no smoke once warmed up, and has good power. I pushed some heavy branches from an old dead tree and had no smoke when I needed power. I was really impressed with the tractor. Thanks. Rod
