504 Vermeer Baler

[Anonymous-0]

A friend of mine just bought a 504 series L
Vermeer round baler. I was admiring it, and I
noticed the two inside belts have a twist in them.
Since I have never seen a flat belt on any baler
with a twist , I though I would ask you guys.
The splice in the belt would have to be taken apart
in order to get the twist out. What do you think.

A single twist is put into a belt to spin the driven pulley in the opposite direction from that of the driving pulley.

If you look at old photos of threshing machines being driven by a tractor's belt pulley, you'll often see that the flat belt has a half-twist in it.

I don"t know any thing about the L but some of the balers had a twist in the belts from the factory for a reason.

I think the twist is to leave openings so you can see how the bale is forming. I don't think the twist on the baler will reverse direction. It would be working against the other belts if that were so. Now on a belt being driven from the belt pulley on a tractor and twisted before being put on the implement then that would make the implement run backward. Lets say you were running a hammermill and for space reasons you wanted to put the tractor on the side opposite from normal. Twisting the belt wound let the mill run in the correct direction.

I think I read somewhere the the makers of the Essex Tri Directional pioneered the twisted belt concept because you couldn't wear a belt out if the pulleys engaged both sides of the belt. Must've worked. I don't recall ever seeing anyone ask about a replacement belt on here.

The half twist located on the front of the baler does assist in the seeing the bale formation which is also indicated to an extent by the monitor. But the most important reason is to allow the material that may follow the belts an area to drop out and back onto the pickup. Most important when baling corn stalks or in high crosswind situations.

you need to get the tension off the belts and go around and get the belts flat THERE IS NOT SUPPOSED TO BE A TWIST. look in manual to see how to get tension off the belts.

You make a good point to check the manual. Your statement as to there not being a twist in any belts is inaccurate. The half twist has been a standard on Vermeer balers with the L and XL series. I have been custom baling with Vermeer balers for 26 years. We have owned 8 new vermeers. I am current in breaking in my second M series baler which is by far the ultimate in round balers. These balers are capable of baling hay #2100 bales per minute. I have also baled the big 6x5 bales of stalks at 54 seconds per bale. This series does not use the twisted belt system instead they use differing length belts running on staggering lower rollers to do the same thing. Older series balers used a roller system to force a twist in the belt to aid in reducing that crop following the belts. these twists actually extend belt life since your aren't building up as much debris to rub the belt.

The twist in the baler belt does not change the direction of the pulley. The twist is put in when the belt is spliced.

Not sure on your model but my 605 K has 2 belts that are twisted and were desgined to run like this.
You can oreder a manual from vermeer for free, just call them and have your serial number handy and they ship it and a parts book out. Took about one week to get mine.
I love my K just wish mine came with Netwrap on it.

If you twist a flat belt running from a tractor to an impliment it will cause the belt to run closer to the hub of the drum. this will keep the belt from running off the drum. You can twist the belt backward and it will run off. You turn the belt inside out and it will run in or out on the drum.
