Kubota b7800 rework

[descanso1]

Hi everyone, I have just joined, although I have owned several kubotas, and a case tractor, I currently own a Kubota RTV and have just acquired a Kubota b7800 with hydrastatic transmission and front loader. Which I am currently modifying to what I want. I have purchased and sold several tractors in the last several months, ranging from a 20 hp Kubota to a Grand l3940 (what a tractor) to large for my needs, trying to find the one that best fits my needs. Finally settled on the B7800, 30 hp, I choose it because it is a basic tractor, no smog, no electronics (less to go wrong), great power to weight ratio, and it fits my needs. Since purchasing it used with about 200 hours on it I have been modifying it to what I want, I have reinforced the top edge of the bucket, added chain hooks, installed a shield over the hydraulic lines behind the bucket, changed the seat to a suspension seat, added a cup holder (coffee in the mornin, beer a little late), moved tool box, added an additional tool box, added front and rear work lights and am in the processes of adding top and tilt, with the assistance of Brian from Fit Rite Hydraulics , Fit Rite Hydraulics - fitritehydraulics.com , He is great to work with and a wealth of knowledge (highly recommend). He is an actual people not a computer, not like dealing with some of the big houses and a lot better than the dealers... When I am finished with the hydraulics I will have the right tractor to fit my needs....... I will be posting pictures as work progresses.

I'm interested in how you did suspension seat, looking forward to pics.

I'm interested in how you did suspension seat, looking forward to pics.

I ordered the suspension seat from Northern tool for 99.00. Actually a very nice seat, adjustable with springs and a shock absorber. A whole lot more comfortable than the factory seat. Install was fairly simple, I had to re drill the front holes and made a cross piece for the rear holes. I disconnected the safety switches and bypassed them. Also the tool box is normally under the seat and since the new seat does not hinge up I relocated it to the front underside of the new seat, great fit and I prefer the location (do not have to raise the seat to get into the tool box.. I will be posting pictures a little later.....

Photos added, top and tilt will be coming as soon as install is finished, waiting for a few parts...
1. Angle iron welded on top of the bucket to add support to keep it from bowing also chain hooks.
2. angle iron to protect hydraulic lines that cross over behind bucket
3. suspension seat and relocated original tool box
4. suspension seat and relocated original tool box
5. cup holder and suicide knob
6. work lites
7. back of suspension seat
8. xtra tool box attached to box scraper (old ammo can) water proof

Seat looks good, thanks for photos. I like the ammo can tool box. I've already bent the hydraulic lines on the front of my loader, should have seen your post sooner.

Seat is very comfortable in comparison to the factory, takes the jolts out.... Almost every tractor I looked at had 3 things in common, the top of the bucket bent down, the hydraulic lines bent or crushed, and the leading edge of the hood damaged. So with every tractor I have had I reinforce the top of the bucket, add protection to the hydraulic lines, and if it does not have one build a brush guard.

How did you attach the cup holder? My B7610 with bent bucket and bent hydraulic lines needs one.

Good job and nice pics.

Sometimes a guy just plain misses the obvious. Thanks for the post. I needed just a bit bigger toolbox and the ammo cans are "obviously" a great idea. Not sure why I didn't think of them on my own since they are the exact size I want.

Any more pics and details about the hydraulics for the top and tilt? Looks like you are mounting a spool valve beside the seat? I've been planning to mount one there on my B3200 for rear hydraulics, but never have gotten around to it.

There are two other postings that have pictures one in progress http://www.tractorbynet.com/forums/hydraulics/300547-adding-tnt-top-n-tilt.html the other is the completion http://www.tractorbynet.com/forums/hydraulics/300929-top-tilt-joy-stick-completed.html.. I mounted the spool between the seat and the right fender using a joystick...
I highly recommend Brian at Fit Rite Hydraulics - fitritehydraulics.com He will give you an estimate via email or over the phone, his kit includes everything except the mount for the spool...
If you decide to add Top and tilt either Brian or I will be more than happy to answer any questions....

Thanks for the links, I had not seen those threads yet. I see you gained some room by swapping seats, I know it is tight there in factory tirm. Not sure if a valve would fit there on mine or not.

Can you take a picture from the top down showing the area between the seat and fender? Then post it I might be able to tell from that..

Nice photos

It's about 2.5" clearance, the seat/fender area should be nearly identical to your B7800. The valve has enough area to be mounted, just not sure if there would be enough room for the lever travel.

If you replace the seat with the one from Northern tool like I have it will give you more clearance for connections and allow a little more space for lever travel. Also if you go with the valves from Fitrite and don't use the joystick, they actually have less lever travel. You will have to modify the linkage for the 3 point control to give more clearance under the valves.
If it identical to the b7800 it can be done. You would have to make a mount to mount the valves to the fender allowing the control for the three point to travel behind it...
If you decide to do it and would like more photos, let me know...
