I recently bought a used Kubota RTV900 with a plow attachment to take care of a long, steep driveway this winter. I think it’s a 2006 and it has about 460 hours on it. The previous owner told me when I bought it that it needed an oil change but I know nothing else about how well it was maintained over the years. While going through the items in the maintenance schedule I discovered a problem with the coolant system. The coolant reserve tank was completely empty so I filled it and soon after noticed a spot of antifreeze on my garage floor. I had never noticed a leak before. I took the protective panel under the radiator off the bottom of the RTV and could see that the radiator itself, the drain valve, and all hoses and connections were dry and tight as far as the hose going into the engine block. I then took off the next protective panel that is right under the forward part of the engine. The engine-facing side of this plate was covered with a mess of oily debris that had to be scraped off and the engine itself was pretty dirty also. I cleaned things up with some paper towels and ran the engine to see if I could spot any leaks. After running the engine for only a few minutes, I saw a drop of coolant on the side of the crankcase right behind the starter motor. I wiped it dry, started the engine again, and the drop re-appeared after a few minutes. I was expecting to find that maybe the water pump was leaking, but I don’t see how that would cause the coolant to appear so far back on the side of the engine block. I can’t see anything else that might spray coolant onto this area. If the cylinder block actually has a hole in it I would expect I would see a lot more problems than just a slow leak of coolant. I am fairly handy but as I’m sure you can tell I’m new to engine work so I thought I’d see if anyone could help me diagnose this problem. Thanks.
I am posting my challenges with replacement tires so others do not go down the same path .
I was looking for some DOT rated 10 ply tires for a Kubota RTV 1100 getting a Boss V-plow installed on it to get a weight rating of UTV + Plow + payload.
I thought the GBC Motorsports Kanati Mongrel Radial Tire (25x10R-12) was just what was needed.
Ordered them in - got them mounted professionally - attempted a balance, received a call from the service center requesting a visit to see for myself why they stopped the install.
Picked up the machine and its unsafe to operate.
The amount of lift and drop is extreme.
We lifted the machine and rotated each tire while mounted and got readings of 75% of tread fairly consistent and round 25% drops in almost 1/2" to more than 1/2".
We attempted to use the tire index yellow dots in line with valve stem and opposite valve stem - no significant improvement. GBC will not or cannot give indexing information.
Working thru the return process now but not holding my breath - Dealer and Manufacture both state since they are mounted they cannot be returned. I dont know how without mounting i would find the defects.
So from my perspective stay away from teh GBC Mongrels on the Kubota RTV's
If you do buy them don't expect them to stand behind their product. You can expect the hassle of mounting, un-mounting, re-mounting, attempting a balance for a tire that turns at slow speeds. Expect they will want video's of all 4 corners, and than expect that it will take you two weeks to even get noticed.....
Don't expect your dealer can do much more for you as GBC controls the process so I have been told.
So spend a little more money and buy a brand you have heard of.
