Looks a lot better than my Buck! You're going to enjoy that tractor. Glad things worked out on the repairs. I'm envious of the turfs.

Yep; I will get out tonight to mow the yard, and get it up to running temp for a couple hours and see how it works.

Everything ran fine. Nice cut. Seems to run pretty hot, maybe that's just normal. Lots of pressure on those radiator hoses. No real leaks found. I noticed a 'ring' of moisture around the bottom of the gooseneck (right on the flat part of the block). No drips, though. Must be a tiny hairline leak there.
Ran it for about 2 hours + yest. w/ no problems.

Is operating temp pretty hot for these?

Does anyone else have a 3-cylinder model (Beaver III, Buck, etc.)?

Does it run pretty hot, under normal conditions? I went from a John Deere Lawn Tractor (LT 150) one-cylinder air cooled gas engine to this Buck, and it's much hotter.

Is it normal for it to run pretty hot? By this, I mean that the motor is pretty hot to the touch after running for an hour +, the rad hoses are very pressurized (brand new, , the hot air coming off the motor from the fan/rad is pretty darn hot. Maybe it's because I'm sitting just about right on top of the motor. :)

I guess it's running normally, but I don't really have a point of reference, and these do not have a temp gauge, just an idiot light.

Been gone a few days. Both mine run a little on the warm side. One day I'm going to get temp gauges. Make sure you have an overflow line on there and run it out where you can see if it starts spitting. The last couple years I have been changing coolant every other year and don't seem to be losing any. I don't have a bush hog and used the Woods RM 48 to trim inside the pasture so we can use the 15' batwing. It's been dry here so not much of this was thick stuff but I ran it for about 3 hours last Saturday. Checked coolant yesterday before mowing yard and it was OK. I did blow the fins out though before starting. Now I gotta get a new belt for the Woods. I use 50% distilled water/antifreeze. Is your radiator good and clean inside and out?

The radiator is as clean as it can get. I sprayed compressed air through it for about 45 mins, back and forth, both sides, when it was off of the tractor. I also had it flushed/cleaned at a rad shop.

Glad to hear it's probably normal temp.

Thanks!
Might not be out of the woods yet. Haven't had much time to look into it, but I noticed that the motor was a little slow to crank last time I started it cold, and I accidentally stalled it while I was mowing (Don't ask) :), and the battery was pretty dead. Oh no. It's only two months old.
So, I either have a drain on the battery, or .... the alternator.
Started right up with a hand-held charger. Those little battery packs are great.

I guess I have to figure out how to find where the drain is, or if it's the alternator.

Par for the course on a 25-year old tractor, I guess.

put a volt meter on the battery terminals while the engine is running.it should read between 13 and 15 volts dc.if it isnt remove the alternator and send it out to be rebuilt.i am using a 47 dollar alt on my d1850.i just got back the original one that cost 125 dollars to rebuilt plus shipping.u can also test the alt with a ohmeter when u take it off.

I will have to get my hands on a voltmeter to know for sure, but this is very, very strange:

It's been so dry, I hadn't mowed in more than two weeks, so the tractor has sat in the garage. I put a trickle charger on it for an hour before I tried to start it. No go. Starter just clicked a little. Headlights were also dead. Put the battery pack jumper on it. Started right up.
Mowed for two hours. Worked great. I shut it down in the driveway, and finished the trim work for about 30 mins. Came back. Started right up WITHOUT a charge. Shut it down again after a minute. Started right up again without a charge. Headlights now work with the tractor running, and not running.

I keep the ignition key in the 'ON' position when I mow. The red CHRG (charge light) on the dash stays red when I mow. Is that normal for the red light to be on during operation? I notice if I turn the key position to off (and not cut the fuel to turn off the motor), the light goes off.

I'll have to see if that's in my owner's manual tonight. Might be.
