857 can’t climb

[857lover 291]

so i’ve been having this issue with my (867) 857 with a six speed so my issue is that it’s slow to get off the line in 3 high but it gets up to a normal speed after a second but like climbing a not so steep hill it like feels like it wants to stop climbing but the engine isn’t bogging down or anything it just feels like the wheels want to stop spinning and then it will stop moving and the wheels won’t keep spinning they just stop and the belt just starts slipping any ideas ?? @danweikert21

@857lover  when was the last time you changed trans fluid ?  have you ever lubricated related linkage movement points?  how is the condition of that idler pulley and  follow spring tension?  every related cross frame mount shaft , should have needed lubrication . just going over a basic functional check , to find the fault spot . with that exposure  level , you should be able to find it , maybe have someone else drive it in low range , so you can visually  see what is possibly going on . leaning toward, rusty linkage movement areas , if there is the slightest delay in spring tension on that  idler pulley , that could cause your issue . just some ideas , pete

has fresh trans fluid just changes two weeks ago when i did the swap the idler pulley spins freely and smoothly and you mean fololower spring tension as in the spring on the other side of the transmission i have a 1267 with what i belive to be the same transmission i can quickly swap springs and see what happns

@857lover  yes , that related shaft movement to spring pull , or failure will affect its transfer of power to the transaxle. my experience with possible rusty issues , is to aerosol lubricant spray and move dry areas till the rust runs out , glad your  trans oil is new , that by itself  , is showing you the way , that the problem is probably linkage related , and not in the trans . , that makes things easier , that clutch pedal should take up very smoothly , with no sudden grabbing , find it , its in the related linkage . greasy , pete

Be certain that belt engages sides of pulleys and not bottoming out. That is where the friction is required. Could be worn belt or pulley.

[peter lena 8,720]

@Kenneth R Cluley agree with that possibility , just sounds like a failure to solidly  make up to complete engagement . most of the stuff  I  have seen with similar  problems , is stuck rusted linkage , bearing shot in pulley . pete

I'm assuming you put the key in for the transmission pulley? Did you ever check the axle shaft keys from the last time you posted about tractor stopping when you got stuck and you said a hub was sliding on an axle? Since this issue started with the trans swap I'm sure the issue is there and not with the belt or idler.

This thread and the "bogging down in 3rd" thread both indicate worn belt. Has that been tried?

By his pics belt doesn't look bad. This problem seems to have cropped up when the trans was swapped. He mentioned one of the hubs was sliding on the axle in his other thread. I want pics of the axles and hubs.

Where, on the engine pulley or the tranny pulley?

i was just at my hardware store picked up a spring and put it on its a little tighter of a spring and that seemed to help a lot im not sure if the wheel will spin now when i get stuck also there is a woodruf key on my transmission pulley and i dont think my hubs are the problem as they have not moved since i adjusted them

im really not sure i look at the engine pulley first because its the easier one to see and the belt like stops movin but the pulley is still moving and after only a couple seconds it starts smoking really fast

So it is slipping on the engine pulley.     That tells me the idler/tensioner pulley is not creating enough tension.       weak spring,  sheared roll pin in the cross shaft,

belt botteming out in the engine pulley

yea i threw on another spring and it seemed to really help it a lot not sure if its 100 percent but its definitely 1000 times better

How bout a close up pic of the engine pulley and how the belt rides on it. That pulley isn't stock

belt was replaced when i swapped the trans less than a month ago

 

[squonk 41,320]

How about a close up pic of the front pulley from this angle ? 

 

I'm wondering if the pulley groove is worn or 2 wide for the belt. That outer groove almost looks like it's for a 5/8" belt

Belt looks too deep in the pulley. The inside flat edge of the belt shouldn't be riding on the inner face of the pulley. Also the belt outer edge is below the pulley outer edge. Compare it to how the belt sits on your trans pulley. You need the proper width pulley.

 

I have the proper engine pulley for that tractor.

its a half inch  belt so you think i need to change the engine pullet to one that is 1/2 ? what size do you think the current engine pulley is

 

[peter lena 8,720]

@857lover from that related belt debris on the engine side , no wonder the new spring helped the tension . another thing looks like the engine pulley is a 5/8 , not giving you the side bite to the narrower belt , probably wrong pulley . pete

Yes you need a 1/2" width pulley. That pulley looks like 5/8"

 yeah but even when i had my 3 speed it always worked really good and ive never had a issue

[squonk 41,320]

Was the other belt a 1/2" belt or a worn down 5/8"?
