BX2670 tire psi?

[buckeyepost]

This is my first post on this forum. Just upgraded from a B8200 to a BX2670 and I had a question about tire psi since the tires are a LOT smaller than my B8200. I ran about 8psi front and 5psi in the rear on my B8200 but I think that might be way to loo on the BX especially when using the front loader. It has turf tires and I mow 5 kinda bumpy acres so like the extra cushion the low psi provides, I'll do a little work with the loader here and there. Anyone have advice on this? Thanks!

Pretty sure the manual calls for 17 (F) and 14 (R) psi with the turf tires. I have been running 19 psi up front as a compromise for mowing AND loader work. As we go back and forth weekly, I could not see fiddling with the pressure so often.

I think I have about 12 F and 8 R right now and it felt a little tippy when moving some dirt last night so I'll bump it up to see if it feels safer. And then I had a dream that I rolled it into a pond!! It's going to take some getting use to the shorter stance than by B8200, that's for sure. I can already tell I'm going to miss it.

Not the kind of thing a guy wants to experience, even in a dream! We have always had loader tractors from 60-175hp. When we recently got our BX, I was amazed at the instability we encountered with a bucket of gravel up front. Nothing at all against the BX series, simply had zero experience with such a small, narrow loader tractor. Adequate tire pressure, appropriate ballast and prudence on the part of the operator are required for safe operation. Truly an awesome machine for in and around the yard. Really, nearly perfect for what it is designed to do.

On Edit: Although rear tire pressure may seem less important for loader work, keep this in mind: It is the only thing that provides any lateral stability with the exception of wheel spacers. The front end has a limited effect laterally since it is designed to pivot.

Be safe, have fun!

Thanks for the input. I've actually just started searching for wheel spacers earlier this morning. Curious to see how it works as a mower tomorrow when I drop the FEL.

buckeye,,, the mowing is a lot better if you replace the factory blades with the gator brand blades. Have one myself and love it.

 

[buckeyepost]

Thanks, I'll look into the gator blades.

Higher tire psi made all the difference in the world when using the loader yesterday. I think the main cause of the instability I was feeling was because of the low tire pressure. I can tell I'm really going to love this little tractor. Put a good 17 hrs on it this weekend.

Good to hear. Give some thought to ballasting if you have not already done so.

The best rule of thumb to follow is what the mfg lists for the tractor to run
them at including loader work. The most common tire failure occurs on the
loader tractors when the tires are over inflated which stops their ability to
flex resulting in the tire breaking instead of flexing. I've watched tires fold
over sideways and not break loose from the rim or damage the tire when it
at the correct air pressure. I've seen over inflated tires split wide open when
they hit a bump/stump/rock when over inflated.

Think of a tire as a balloon, the higher it's inflated the thinner it gets. If the
balloon is blown up as large as it can get one touch with a pin it explodes.
Doesn't happen as easily if it's not over inflated.

PS: I've lived that tipping over real time and the "pucker factor" once you've
actually went over is far worse than the nightmare while sleeping. Loaded rear tires and box blade or some counter weight always now. I'm still thinking
I'll add wheel spacers too with my sloped yard in a couple placed that make
my butt pucker every time I mow thru them. Not good!

I have found that loading the front as well as the rear tires, and adding 230 pounds of rear ballast provides the best stability when using the loader. I am frequently moving loads of rocks that weigh in the 500+ pound range. Before I loaded the front tires, I had one come off the bead while turning with a loaded bucket. I ended up having to replace the tire because the sidewall became damaged from the rim. Now I run the front and rear tires loaded with 75% water and recommended air pressure and have no problems with tires since.

Loading the front tires may help with traction and steering on snow or with a heavy 3 point load. However, loaded front tires and front wheel spacers when using the loader will have little to no effect on stability due to the front axle pivot. When a front wheel comes off the ground you are already in deep doo doo...

I found it quite strange that no one asked what tire style the op was running!

If I can assume looking at the avatar picture is correct, If my eyes are not deceiving me I see turf tires which have 4 ply rating and are lesser than the R4's This can solve some of the squishy feel when under load.

As stated air pressure is the key along with ballasting. As far as loading the tires on the BX series, our dealership recommends ballast box due to loading the tires only adds 160 lbs. to center line of the rear axle. While adding the same weight to the box further back has a better effect due to being further away from the fulcrum point. Plus the added bonus of dismounting the box to tread lightly when conditions dictate.

Probably no one asked, "I found it quite strange that no one asked what tire style the op was running!" because he states turf tires in the original post.

I gotta stop reading these post at 3 AM in the morning. Not my time of day.
