All things tractors thread


I’d second Hillbillyhort’s numbers. It depends on the exact type of lead-acid battery you’ve got (flooded, AGM, gelled) but 12.05v is around 50% charged or a bit less by my charts as well.And you will get different voltage readings right after charging or when a load is on the battery. So most accurate to take it a few hours after charging (either by wall charger or the tractor’s atl/gen) when its been idle for a while.

Regardless, your tractor batt is pretty far down whether at 50% or 45% or whatever. Be good to throw a charger on it for a while and get it back up to near full charge. It really makes starting in cold weather a whole bunch easier.


OK, I’ll check the voltage again tomorrow to be sure what it’s really reading.

Any comments on the tire question?


We used to have tractors with fluid in the tires and I don’t remember the weather having any effect on them.


I would say just never let them get low to the point they could roll off the rim. If using a loader never take a chance with under inflated front tires.


Guess you’re liking what you’re seeing in Dallas tonight, yes?




Did I say GO BUCKEYES :football:


Best to find out what the rated pressure is for your tires, then use an auto-type tire gauge to take a reading and see. If you have fluid in the tires for weight, you want to roll the tire until the air filler thingie is at the top. That way there will be some air there to measure, if the stem is lower you’ll be pulling fluid out when you try to test.

I have not found weather to have any more effect on tractor tires than they do on auto tires. All loose some pressure as the temps fall.If a tire was on the low end in the summer it can easily get very low on a really cold day.

I’d trust your gut on this, if you are seeing the tire(s) as lower than before they likely are. Time to get the air tank and pressure gauge out. Oh and keep in mind, if you fill them up when it’s 0F out, you will likely need to let some air out once temps get higher. (not a bad idea for the cars too).

And I’d second BobC’s comments, low tires can be dangerous if you are using your front loader.


Thanks. To be honest I don’t recall how low/high they were in the summer. I just assumed they were fine then, so I need to be more diligent about them, just like oil and other fluids. I just happened to look down at them as I backed the tractor into the barn yesterday.

Good call on getting the valve on top before checking the pressure, and not letting out any fluid. I called my BIL and he has a pump I could use if need be. It’s supposed to get colder (single digit lows) next week, so I prob won’t be messing with the tractor then.

I don’t have a loader on my rig, so no worries about the front tires.

Have you had your rig out in this cold lately?


Have not had my tractor running since I parked it a few months ago. It been unusually warm (most of the time) this fall, and we have not gotten enough snow to make the tractor necessary. I did put the battery charger on it last week right before a recent cold snap, but that storm missed us for the most part (2" of snow), so yet again did not need the tractor.


If you have radials, they won’t show any increase at all with higher pressure, unless they are super low. Radials are designed to keep the same circumference pretty much regardless of pressure (unless they are really low). Biased tires show low air a lot better.

Also I wouldn’t run fluid in tires on a chore tractor. It just causes the rims to rust out, and is not much (if any) benefit on a chore tractor. I drive in a lot of mud with mine, and prefer the lighter weight of non-ballasted tires. It helps me “float” a little better on top of the mud.


I checked the battery voltages again, they both are at 12.30V, so not as low as I had thought. But, at that voltage, it’s still at about 50-60% charge. Saying that, they could still stand a bit of a recharge.

How can you tell if you have bias or radial tires? All the info I could get on them is that they are Alliance 16.90-28 Power Drive tires.


Mine have radial printed on the tires. It’s possible some may just have an “R” somewhere in the size printed on the tires. If it doesn’t say “Radial”, or have an “R”, they are biased tires. Most people put biased tires on chore tractors because they are cheaper, but they sell radials for pretty much any sized tractor.

I only put radials on mine because of some technical issues regarding the forward assist. Radials mostly help with traction and fuel efficiency in planting row crops. They really aren’t much advantage with chore tractors.


My wife needed something out of the cellar down the hill, so I had an excuse to go out to the barn and check the tires again. This is what the tire really has on it: Alliance 14.9-13-28 358 R-1 Power Drive. So I guess that means it’s a radial.

You mentioned radials won’t show any increase with higher pressure, unless they’re super low. Would that mean that if this tire looks low then it’s really low?

Looks like I’ll need to get some air in it before it gets too low. The tire is rolled over so that the valve stem is on the bottom (that figures), so I’ll need to crank up the rig to roll it around to the top.


Well, armed with all the data on the tire, and checking online, I came up with this:

So, the R-1 doesn’t mean it’s radial, it only means it’s a standard field tire, for use in mostly dry conditions. And the BIAS in the title kinda seals the matter.

Anyways, I’m done with this for now. I’ll get some air in it when it warms up a bit. Looking at single digit lows all week. I will get the batteries charged up, tho.

Thanks for all the replies.


That’s right. I should have mentioned that. R-1 is the general (multipurpose) tractor tire tread. Along with R-2, and other R designations followed by a number or a number and a letter, which are all designations for tread depth and spacing.

If the tires were radial, they would say something like 14.9R28.

If your bias tires look low, they probably are. Tires lose a little pressure every year, even if they don’t have any leaks. Air leaks through the sidewall, just like air eventually leaks out of the walls of a balloon.


Sooooooooo. Evan after buying a 55 horse tractor I still found my work was much tougher and heavier duty than expected. If you have read this thread you are aware I had some issues with my Mahindra. I am happy to say once fixed I had no more troubles with the 2555. Very nice tractor. But anyway. I took an opportunity to get full trade and 2 percent better interest rate. So I bought the M power 75. Full size tractor. 75 horse. Less frills than the 2555 but a much bigger more powerful tractor. So far very happy. I went with a new woods mower too!




So… I have a lot of saplings and small trees. Some larger trees too that must go. It’s VERY hard on my new mower to drive over and cut them down. I also have stumps some of which are hidden in the trees and brush. I saw this implement and really think it’ll get the job done with out tearing my other equipment up.


Did you buy it or rent it?
