Header size

How big of a header is everyone running on their class 8 flagship machines? How about your 7088 or equivalent? I need a new header for the 7088 and am trying to figure out size, I have a 35 on the 8120 so I could switch it to the smaller machine and get a 40 or something else, just wondering what everyone else is using and pros or cons.

Thanks

How far will your machine spreads the straw, how long are your fields, and the size of the combine grain tank all factor in the header width decision for us. I want my combine to spread the straw the full width of header cut so the nutrients from the straw are evenly put back on the land. I want to have a header width and grain tank capacity combination so I can combine a half a mile there and back before the combine hopper is over flowing. That way my trucks or grain cart do not have to chase the combine all over the field compacting it to dump it.

We bought an 8120 and a 40ft FD70 this year. The combine has the 75mm cylinders and wouldn't lift the header until we turned up the pressure. Even then it didn't lift very high. We made it thru harvest but bought the 3rd cylinder kit from Combine World. Haven't got it on yet but hopefully that solves the problem.

Run a 35ft draper on my 7088, handles it fine in small grains.

I had the same problem with a 3152 35', found a couple used 90mm and now it works good, you might want to change the lateral tilt cylinder to the HD version also, I haven't yet but it's on the list, it doesn't want to tilt properly with the smaller cylinder on it.

I've never really thought about the distance cut as a factor before, I was thinking more along the lines of speed in the field. 40' will be kinda a pain to move down the road around here, but I can get 40' for quite a bit less $$ than another 35' or even a 30'

If you have to road a lot with the header on, a 35ft is a lot better than 40. We have 40 ft Macdon fd70 headers and pull them behind the combine if we are going any distance or down busy roads. You can ruin a header quite fast if you hit a sign on the end of it going in road gear.

I think you SK people may be the only people in the world (outside of AUS) that could even think about roading a 35' or 40' header! Here in IL, even a 20' is now to wide, as the traffic is just too heavy on almost all roads--you spend all your time sitting in the ditch waiting for cars to squeeze by. I have a friend in NY that says they really can't even transport a 15' safely on the roads anymore. And lets not even talk about the EU....

No, AB CA people too!
Only it’s a 40’ or 45’ decision.

Starting to hear 35’ chatter, roading, big crop and more flex stated reasons.

We move between fields with the headers on, but only on gravel and with a pilot truck. I saw a Hutterite drive right up Hiway 4 south of Lethbridge with a 40ft header. It's a 4 lane. Truck behind was stopping traffic.
