I finally bought a new seat for the
B7100 on Friday nite and my neighbor and I installed it Saturday. It's a suspension seat with 2" to 4" of vertical travel, weight adjustable, high back, and fore/aft adjustment. Although I bought it at the local TSC store, the Northern Tools website has the same basic seat, #17491. I opted for a seat without fold down armrests and went for one that has molded armrest "stubs" that kind of surround your back and inhibit lateral movement. I sat in the seat with armrests and found the one I bought generally more comfortable overall for me, especially the lower back support.
The installation was interesting. I made a 9" x15" plate from 3/4" marine plywood that I mounted (bolted) on the brackets that held the adjustment track for the original seat (I'll probably switch this to a 1/4" steel plate when I get some plate steel). I had to take this approach in order to position the new seat far enough back on the tractor since the front edge of the new seat extended so far in front of it's mounting plate. In fact, the back of the base is mounted against the ROPS posts, although still allowing sufficient room for the suspension system and access to the top link pin. I then bolted the seat adjusting plate to the plywood platform. Not at all difficult, it just took a while to figure out the best way to mount the new seat.
A couple of observations. With the new seat I sit about 1 1/2" - 2" higher than in the original seat. The new seat extends about 2" further into the operator area than the original, even moved as far aft as possible, so some room was compromised. Operator space was initially a concern.
Now, the really great news. The new seat is absolutely, positively, undeniably, and beyond a shadow of a doubt the best $148.39 (plus a few nuts, bolts, washers) that I've spent in a long time. Although it sits slightly higher and a bit of room was compromised, but not enough to really matter, the ride and action of the new seat is at the very least, excellent. My son, who is 6' 3" tried it out and gave it a stamp of approval as well. I'm 6' and found the arrangement to be all I'd hoped it would be. I think I actually like the positioning in relation to the steering wheel better than the original seating position.
Yesterday (Sunday) I spent about 3 hrs. in the afternoon mowing & chopping up leaves before pulling the mower deck off for winter. For the first time since I've owned the
B7100 I had two notable experiences: 1) I had support for my lower back while driving. 2) After 3 straight hours in the saddle, I got off the tractor without a stiff back or sore butt. As far as I'm concerned, that seals the deal for me. The only thing that has been adversely affected by the new seat installation is reaching the 4wd lever. It's more difficult now to reach down below the Hi/Lo range lever, but it's not often I switch between 2wd and 4wd, anyway.
My wife thinks the seat looks a bit "big" on the
B7100. Maybe it does since the seat is actually designed for larger ag equipment, but it does a nice job on the little Kubota. Frankly, don't care how it looks.
I bought the seat from TSC vs. Northern Tool for a mostly economic reason. Both sold the same basic seat for $139.99. With Northern Tool, adding a shipping charge of $21.68 brought the total to $161.67. At TSC, adding 6% sales tax brought the total to $148.39. And, at TSC I could actually sit in the sample/display seats and see which one fit me the best.
Unlike a lot of folks, I'm somewhat technically challenged and don't have pictures to post, YET. I'm going to borrow a digital camera this weekend and will hopefully have pictures showing the installation next week.
I just wanted all those folks out there considering seat upgrades to know....it can be done with a little thought, ingenuity, and help & advice from your friends. And, it's really worth the $$ and a small time investment in terms of comfort. The only question I've asked myself the past two days is: "Why did you wait so long, dummy?"
