I have heard that I will learn to hate the conditioner rolls on my newly aquired PT-7 because our hay is varing height. some of the taller grasses are 3-4' and the bulk of the grasses are 18". Any thoughts or comments from you who have used this type of machine?

Thanks, Ted

The guys who complain about Hesston rollers think that just because they don't look as agressive as the NH intermeshing rolles that they aren't as effective. But what you won't see on the back shield of a Hesston is the pile of leaves that those NH rolls have stripped off the alfalfa. Just keep the tension to the book specs, and you won't have a problem. As to anything in the cutting mechanism the key is keeping things sharp. It's the difference between cutting paper with sissors or chopsticks.

i'm a pt-10 user, know nothing of pt-7, but i'll throw into this. does your pt-7 have a push bar just infront and above the reel?. it will push any tall and reedy hay over and away from the sections so the sections get a good cut on the grass. also an optional sprocket is available for the pt-10 reel to speed it up to feed heavy cuttings into the rollers (and away from the cutting sections) faster. keep (extra) good sections and guards at extream right and left of the feed chamber. thats where clogs will usually begin first. there is also an upper and lower "grass guard" at the far side of the feed chamber that keeps grass from the reel bearings. i don't think that most people would notice them if they were missing. but the guards make a big difference in clogging. keep an eye on the pattern of the grass behind the haybine. if you notice any uncut or ragged grass, stop the forward motion of the tractor. its likely that grass is hanging up on the guards and getting ripped, not cut. if you are not carefull a big clump of this grass will go between the rollers and bind it up. if the clump is not too big, i usually just back the haybine up a couple of feed to pull off the clump.

hope i'm not wasting you time.

Ditto on the pivot mech. We borrowed a neighbors PT-7 last week and had the same problem.

I agree with Gary. Keep the nuts and bolts on the pivot mechanism torqued and inspect them frequently. Get to know the sound of your machine so if it changes you will notice. And of course when you do stop to check something you should disconnect the PTO and shut down the tractor.

Amen on the nuts being tight. Had to rebuild the upper and lower holes this spring as they got elongated and I couldn't get through a field without tightening or replacing the bolts.They Do a nice job cutting, will plug easier if the grass is wet or the rollers are slack. Happy haying

So how tight do the rolls have to be?

We used a PT-10 for about 15 years to cut just about every type and height grass imaginable, never had any problems with the rollers. The pivot mechanism for the sickle bar, well that's a whole 'nother story...
