Enough of that radiator location!

Man, I have so had enough replacing my radiator. I love Kubota and have forever, but forever I've had to ask what Kubota was thinking with that rad placement? From 04 up they did a couple modifications, one of which allegedly created more fresh air but, in doing so, also created more openings for sticks to come in while backing up, and of course skewering the rad. No matter how you color it, that under the seat thing stinks! One mod I used a triple-core ATV rad and moved up front and evicted my winch (OEM Kubota rad wont fit up there)...this worked a bunch better, but was still subject to the occasional stick and copious amounts of river mud to be cleaned out. Next, an up-kit on the hood with holes drilled in hood for the hoses...this was cool except I hate looking over things on the hood but more importantly, I lost the use of my hood...one hydraulic leak had me quickly abort that one. Both these first mods had my fan seldom EVER turning on, even in Summer, so I knew I was making progress. The final rad mod came with sacrifice, but plenty worth it to me, and is getting ready to go from trial mock-up to a permanent version...on the rear roll-bar. We have wore helmets and spent about 50 hours in the woods exposing it to our bobbing/bouncing heads, crashed through everything imaginable, went without helmets and ear protection to see how loud and annoying the fan would be right behind us like that, and it's a dream! Machine has never ran cooler, and out of a 6 hour ride that fan literally kicked on twice when we were in low climbing a bunch of hills. 50 hours later and not a spec of ANYTHING on the rad-screen, and we went through some stuff you'd not like to ever walk through! To trial this location I used broadway copper 90s, 1" copper tubing with no rigid connections a the rad nor the nipples on engine...rad-hose adapters at both locations. Bed still goes through full articulation but had to remove front panel. Once I go back and use short 90s and pretty it up the whole box can go back on. Expanded metal cage with access through the passenger-side will complete it. The access is for gloved hands...the wife decided it was the most awesome hand warmer! Now all my ridding partners keep grabbing my pipe too! Dang, did that sound right? Anyway, in cold weather, the rad feed pipe will warm your cold hands and gloves in seconds! Probably will only work for the 900 though, as the 1100s rear glass would likely cause a flow issue, so what would be the point. The biggest sacrifice would simply be that you'd have to be careful throwing huge things in the bed, but with a heavy enough expanded metal cage, only so careful. This machine we use more for recreation in the Hatfield McCoy trails, and hunting, so I really didn't care about not being able to toss a shipping container up in the bed anyway.

This is only one minor modification, by the way. This machine is so modified it hardly can be called a 900 anymore; Has an 1100 drive-train (Required front cross-member being cut out and a new one with cradle-mounts constructed and welded back in 1 1/2" further forward. Used the 1100 donor machines (totaled) hydraulic tank and relocated it to right behind the passenger side of the cab, where the breather used to be. Custom heavy frame was welded together for that location...now the machine is much better visually balanced with the tank on one side, and twin gel batteries on the other. One tank to deal with now, and with the radiator out from under there as well, I now have a large under-seat compartment for straps, my hot-swappable 4500 pound warn winch that is on a two-inch hitch-mount for both the front and rear of the machine, and other goodies. Also upgraded to the new seal drive-shaft. I wanted to turn the heavy 26" Baja Cross 8 ply tires without a loss in performance, and I hate turbos, and so to me, the 1100s heart transplanted into the 900 machine was the obvious choice. I don't want an enclosed cab, but I sure wanted the 1100s upgrades. Just figures that after I go through all these mods, Kubota basically did the exact same thing! Anyway, without a turbo, I can consistently get 32 MPH on flat ground, and those 31 pound 26" Bajas are still churning through and up everything better than my 900 engine did with the 25" 350mag tires. Satisfied for now, I guess. Franken Kubota will always undergo the saw though...just who I am. ;)

Thanks for the warm welcome, folks. Been an RTV owner since 2005...just always been too busy to join any discussions/boards/forums, although to be honest, I've benefited many times by viewing from the sidelines. A wealth of information resides on your site, to be sure of it. Mix that with my own trial and error/experimenting and these days I'm sure there isn't much I can't tackle on these unique machines. I have a couple "Go-Fast" machines for when I feel the need, which isn't too often anymore but, it cracks me up when my non-RTV owning buddies hit me with the never ending question, "Man, why do you spend so much time and money on a machine that weighs a ton and hardly does 25 MPH?"...the answer is usually answered at some point during the summer when my 1 ton moose drags their broken-down and/or out of gas quads miles through the woods...don't you think for a moment I don't bring it up in those exact moments! Anyway, I look forward to participating in and hopefully contributing in some way to this site. I enjoy viewing everyone's photos and insight!
 
Carbonitehunter, welcome to the forum. As always, I'm interested in the meaning of you handle, Carbonitehunter. Mine is just my initials.

Has the frame been cut on the last picture posted? Just curious, and maybe a little concerned if it has been cut. Just the engineering coming out of me.
 
Carbonite limbs are used on my favorite hunting bows by Hoyt, and although I have several bow options, I still hunt with the Hoyt Enticer with those limbs. Hence, CarboniteHunter. No cutting was done on the frame rails...a frame was constructed for the exact dimensions of the oil tank, and welded on low heat to the frame rail, then gusseted...actually adding to the structural integrity as opposed to detracting from it. The new crossmember for the engine cradle is actually twice as heavy, as well as box-tube, which is already stronger...also gusseted. The downside, if there is one, is the beef up added about 30 pounds to the machine in steel. Gusseted in a few other places as well...this thing could be dropped from several feet and would likely survive it. I have a bit of an engineering past as well. ;) If I were to say that Im hard on these things, it'd be a major understatement!
 
Not exactly a Kubota but, this me and my other passion...Screamin Eagle CVO bikes. I thought about fitting my RoadKing with knobby tires and consolidating my goodtimes...not sure if that's be cheaper, or more expensive. Either way, I'd probably be no farther, nor less in the dog-house...pretty-much were I exist. I have a bit of fun in here though...I just dont get cooked very many meals in here. :(

In this photo you can see the spiked steps I added...got tired of ripping my shins off when it was icy and wet...now if it happens though, I'm probably going to need a few stitches. ;) Can also see the 1100s bumper I added...I think it does a better job of deflecting brush away from the plastic, which I've replaced on this machine three times already. Last round I bought off ebay and it was orange, so I painted it with textured plasticoat...hard to hide orange in the woods when you're hunting a mile from your machine. Lost a Polaris Sportsman that way. Anyway, we have the 1100 as well, but I hate it...that's the wifes. Insects start biting, and she loves that thing. I hate being in a cab though...I have a Jeep for that.

I have a CanAm XMR 1000. XMR stands for Extreme Mud Racer...a quad factory designed strictly for mud racing, none of which I actually do. I just wanted a machine that flat would not get stuck in the mud along White River here in Central Indiana. Anyway, this machine is built off the "Two-Up" platform CanAm makes for a passenger...they just majorly tweak it and stuff 30 inch Gorilla Tires under it, and add those spiked-steps so you have something to stand on during water/mud wheelies. To me they put my feet in an awkward position, so I removed them. One day while studying the machine (RTV) for something to do about the freshly bruised shin it gave me, I remembered those steps in a cabinet, and bam...my foot has never slipped again. They fit perfect over the edge of the floor support...drill one hole center and it actually looks factory. Sure you could buy a set from CanAm's parts site...aluminum, and my legs salvation!
 
Carbonitehunter, great looking bike! Thanks for clearing up my vision. Now I'm no longer concerned about the frame of your RTV. I now remember the carbonite limbs.
 
BaiJiu, not even close on guessing my name from the initials, but a colorful attempt. Now yours seems intriguing, but I'll not allow my imagination run wild on it.
 
Pepr if you aren't familiar with China you wouldn't guess mine. It's actually my dog's name, I borrowed it for this site.
 
Good pics. Looks like a wild bunch you ride with in post 14. that pic could be on the front of a magazine cover. :thumb:

Love the spiked steps. Excellent idea. :clap: :clap: :clap:
