Combines Reel Speed Problem

what combine do you have this puppy hooked up toIJ if its a 1660, check the belt under the cover where you hook up your hyd hoses on the feederhouse. also, there is a ground wire near where the feeder pivots on the left side that sometimes causes wierd stuff to happen - this is the ground for the reel speed valve.

Check to see if the shaft in the end of the reel has a broken weld. This happened to me this fall and it acted like you described.

We had the same problem as well and after looking every where else but somewhere simple, I tightened up the belt (spring loaded) under the feeder house (it's on a ready-bolt spring tensioner) and that helped and then when we went into wheat it acted up again and didn't have any control, just kept going slow. Turned out to be the eye connection where the feeder house pivots was loose. Tightened it up and walaa, never a problem again (knock on wood!). ;-) Good luck. let us know what it was, that's where I'd put my guess though.

It's a 1ate model 1440.

IN THAT CASE...... there were 2 types of reel drive systems used on the electro 1440's (sn u050000 was the dividing line). the early electro models used a combination pump_valve assy, the later ones used a seperate valve to adjust the flow. Either way, sometimes the electric motor that works the valve goes bad. check to make sure the motor is getting power - if it is, possibly the motor is bad, or the sprocket is stripped out. below answers also apply if you have auto-reel-to ground option another possibility is that on some models, there was a reel speed sensor that senses the reel (you would have 2 electric hookups if you had this option, 3 if you had field tracker). is the sensor or wiring damaged on the headerIJ (same sensor is used for fan speed on the combine, you could swap sensors, and it should be 0.060" from the sprocket) and yet another possibility - does your MPH read out correctly on the tachIJ the auto reel control uses the same sensor.

Get this .....my chaff spreader runs from the same hydraulics as my reel. Why would that increase and decrease accordingly but not the reel speedIJ

Flexhead,that also happened to me.I just turned on the head and the reel would hardly turn and would not adjust at all.This was on the right side of a 30' head.

I mis-read your complaint - I was thinking your chaff speed change went with the reel speed change. "MAC" probably has your answer.... if not then something might be wrong with the reel motor, but that would be "reel" rare......
