M5-111 @ 0.05mph

[Atypical_decorum]

Someone is trying to sell me a M5-111 low profile with a 12spd transmission and I imagine a creeper gear set. They said they've been on the tractor and it does 0.05mph at 2000rpm.

The tractor I returned, a M9960 12spd did 0.17mph at 2000rpm (1st gear and selector switch on the "snail").


Does this seem realistic @ 0.05mph and 2000rpm?

The manual shows creeper 1 to be 0.23 mph at rated engine RPM of 2400. Should be simple math to calculate the speed at 2000 RPM.
0.19mph?

OK, so not 0.05mph, but in the ball park. Tha k you for your worthwhile contribution to the discussion.

Just keep in mind the Low profile version has smaller tires and therefore should get lower speeds overall.

The numbers I found were not for the low profile version...

I’m curious why the difference between 16.7 feet per minute and 4.4 feet per minute is important in tractor considerations? Do people no longer know how to use a clutch?

Ha, it took you a minute to do that math before you made that snarky comment didn't it.

Put yourself on a 35 degree slope, dragging an angled blade to make a walkable path. Hitting ruts, running over debris, and steering around trees. Now tell me if you want to be doing that at over 1mph instead 0.1mph, or riding the clutch the whole time...

I get what you're saying but these creeper gears, more often than not, are not meant for high pulling loads due to the risk of simply twisting shafts or grenade gears inside the transmission because of the crazy amounts of torque those gears create. The manual should clarify this better though.

Do you feel that’s the primary task? If so I think you should be looking at a dozer. 35 degree slope is probably well outside of the specs for the M5 other than possibly straight up slope.

I understand that. The tractor would pull the blade fine in a non creeper gear, but the stability of the tractor on such a slope at higher speeds is questionable. So, I'm using it for it's slow and stable speed rather than brute pulling strength.

I don't "feel" anything about tasks - I do not let my emotions dictate my tasks.

The aforementioned is a task that must be completed. The LP version is capable of steeper angles than a regular version. Ballasted duals or spacers on singles should get me closer to where I need to be. The steepest I actually will put a trail on is about 25 degrees. Though a rut or two will certainly get me into that 30+ range until I smooth it with the blade. My property also has plenty of areas with 60 degree slopes, but I'm not going near them.

To note, highway overpass sides have angles in the 45 degree range and bigger tractors than an M5 with duals grade them. I think that 35 degrees is well within the capability of an M5.

Ohhh the irony.

Good luck with your tractor.

I have creep gears on both my M9's and I only used them for test plot planting. I would NEVER attempt a 35 degree slope on any rubber tired tractor. That is nucking futz.

Only with a counterweighted mower attached or something to offset the angular weight. Better look closely at them.

IMO, you try that, you won't be posting on here anymore and that may not be all bad.

I had to take you off ignore to see this. They didn't have counter weights. Just ballasted duals and scrapers.

Ok

It seems like so many posts on here get derailed by a few people.

Does anyone have input back on the initial post?

I had chatgpt do the math. From a 71" tire to a 51", 1mph drops to about 0.75mph. I have to see what the height is on a standard M5 v LP to get the right calculation.

 

[RjCorazza]

I gave up with the actual calculation, but it appears that the M5-111 Standard tire is 61.7" diameter, and the M5L-111 tire is 50.6".
Unfortunately, it's also possible that the low profile tractor has different gear ratios.

Glad you found the ignore feature as I have you in the same boat. Nice thing about it is, you don't have to toggle it on and off, just click on the drop down below the ignored content and it will come up... one time. I very selectively look at posts from what I consider to be a'holes and I'm sure you do the same. Tit for tat so to speak.

I still maintain you are 'playing with fire' and may or may not get burned, depending on your abject stupidity.
