eo1bart 42 #1 Posted 3 hours ago The other day after plowing I was backing up in low gear and I noticed the tractor was surging. Not the engine, what I mean is when looking down at the rear wheel the tractor would pause and go every few seconds. What would cause this? The gearbox was completely rebuilt last summer, also I installed a new drive belt and clutch spring. I've already inspected these and the hubs and everything looks good. The machine has been working great since all the work was done. Admittedly in the past month I have been working it hard plowing/snowplowing, most of which is on an incline and even though I have wheels weights, filled tires and chains I have been spinning the wheels a lot especially in reverse. Looking for some ideas before tear-down and differential inspection. Share this post Link to post Share on other sites
WHX?? 54,240 #2 Posted 3 hours ago Double check the hubs/input pulley first. Put witness marks on them & see if you have sheared a key. Any strange noises indicating you may have stripped a gear? Drain the oil and look for bits of silver and metal flakes. 2 Share this post Link to post Share on other sites
peter lena 9,677 #3 Posted 3 hours ago @ e01bart , related pulley issues ? get a helper so you can see possible reason / cause , your rotation relation is showing you the way , maybe a low range look so you can ,carefully see what's going on , your recent hard driveline stress , probably woke up a solid rust related , issue , hub , key way blow out , pete Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,962 #4 Posted 2 hours ago You may have backed into some snow and it has got on the transmission pulley/belt causing it to slip. That does not happen for long and the belt gets it's grip back. Going forward you have usually removed the snow ahead of the pulley so does not happen then. Been there done that. 2 Share this post Link to post Share on other sites
