Rear fenders/seat pan difference

Recommended Posts

GWGAllisfan

There is a slight difference in the mounting bracket.from what I remember, the bolt holes for the seat pan are slightly further back on the 7100/900 series. This, if the newer pan is bolted to an older tractor, makes it swing forward and miss the latch bar for the seat. I saw this with a 900 series pan in a B-212, then compared it with my 712, and realized the difference.You can see the extra drilled hole on the bracket in this picture.

One difference I see is the mounting hole for the rear light is different. The earlier seat decks (like a 3012 lasting until the late 3400 series) is completely flat around this hole. The newer seat decks (7000-7100-Soveriegn series) has a incline around the mounting hole so that a light without a hinge would angle down a bit.

The 3400 seat pan has a depressed leading lip as can be seen in this pic of a 3146H seat pan:

The 7000 seat pan also had the depressed lip (7016H):

A/C built Homelites had the same depressed lips (T-12):

The 7100 didn't have the depressed lip (7116H):

Nor did the 17GTH-L:

Nor did the latest model Sovereign (75th Ann):

Also notice the different stock holes in the various pans. They changed over time and the latest Sovereigns had very few holes. I had to drill some to install the "old style" flip forward seat hinges.I never experienced the problem Randy mentioned about the mounting hole locations. But I've only swapped seat pans around on RBT's.

Glad you have one found.

I went back and looked at my 712, and it's seat pan has the straight, shorter mounting tabs. It may just be that the 7100/900 series is different from earlier ones.

My understanding at this point, (based on sample of 4) would be 7000/700 series and back- direct bolt on, 7100/900 to earleir, need two new bolt holes.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
