I’ve had good results on my B7100 since 1984 by using the glow (1 minute)while holding the decompression knob out( allows the engine to spin over fast) then slowly pushing it back in! What great little machines they are!👍
Mine has always started off of the glow plugs and heat gun. This video was the first time I've ever pulled the decompression knob while trying to cold start. That's after 12 years of constant use. These are amazing tractors for their size. I kind of want a second one. As another seasoned B7100 owner, your input is appreciated any time. Thanks for watching!
@ Thanks! To be honest, I typed that comment before you actually used the upper cylinder decompression knob In the video!Was gonna delete it but thought well it’s just confirmation others have used it too!😊I always liked the fact that these machines were called “micro tractors” through the years.They should be called “mighty tractors”!👍 Keep on Kubotaing!!
Install a block heater. We have a Iseki TX1300 mini tractor with an aftermarket block heater (DEFA). Starts right up after 30 min to an hour, even in the coldest temperatures over here in Norway!
I'm thinking about it, but we normally only get sub zero temperatures for a few days a year. Another viewer told me about a magnetic oil pan heater that I might look into for a solution without permanently installing anything. Thank you for watching and for your input!
Leave trickle charger on the battery when not being used outside at all times on mine also helps and a magnetic oil pan warmer from tractor supply helped me also.
I used to put a battery maintainer on it, only when temps were to go well into the negatives though. But, it's been a couple of years since we had a real winter, and the battery has a few more years on it. I'll start putting the charger on it sooner now. Never tried the magnetic warmer. I'll have to look into that! Thanks for watching and thanks for your input!
I leave my maintenance charger on 24/7/365 it helps a bunch only exception is if I'm out working for the day between starts. I also keep one on the 0 turn year round. The way I figure is the less work that battery has to do on a first start of the day the better, hasn't failed me yet My tractor also lives inside, my truck doesn't fit in the unhealed garage, and having the tractor wam(er) is way higher on the priority list anyway especially during the winter
I generally only put the maintainer on mine when temps are forecasted to get into the negatives. Otherwise, I've never had a problem with this battery. It can sit for a couple of months and still be fully charged, unless it freezes. I've had this one a few years though, it might be starting to wear down.
yeah..those first couple attempts were at a super slow cranking speed. For my b7100dt if it doesnt start within 5 seconds im doing something wrong, namely not holding the glow plugs long enough, that is where the trickle charger comes in handy, yes the trickle charger won't keep up with the glow plugs but it certainly does help the battery to use that much less of its own power to power them. I do 100% agree on the no snort juice fkr a small, or really any deisel engine though P.s. ive never had to use the decomp knob and im pretty the cable and linkage on mine is frozen lol.
Yeah, mine usually starts right up. You can see that in the snow plowing video that I posted earlier this week, but it was about 27 degrees that day. You can also see my disappointment in the sigh after "not yet" on the first attempt. I pretty much knew right away that I messed up, but I didn't think it was cold enough to freeze the battery. A modern battery maintainer or trickle charger does more than just provide extra juice, it keeps the battery warm. That's what it needs more than those few amps at startup. In the past, when we hit -20 degree days, I've brought my truck batteries in the house to keep them warm, only taking them out when needed, never using a charger. Might do that with the tractor battery on this next dip. This is the first time I've ever needed the decomp knob in about 12 years of owning this tractor. Somewhere in a recent video, I reinstalled and properly adjusted the cable, explaining then that it's only really useful for weak battery and cold starts. Now I'm glad I went through that maintenance. Thank you for watching, and thanks for your input!
My B6200 has a small hook to hold down the clutch. It's not a safety thing. For extreme cold start, holding in the clutch prevents the input shaft to the trans from turning that cold gear oil. Allowing for a faster engine crank speed. I always use the compression release all year around for a cold start. That is what it is for. Saves having to replace the starter. If you used the compression release it probably woulda popped on the first attempt. It would allow the hot air into the cylinder faster as it holds the intake valve open. The manual says to put a battery charger on the battery once a month all year long. The little dynamo will not fully charge the battery in normal operation. In extreme cold start the battery charger is going to make a huge difference in a successful start the first time. I moved the battery out over the weight rack and it is twice the size of the original battery. Helps add front end weight as well. Kubota batteries are undersized to fit under the hood and to help the dynamo top it off. Your B7100 might have the improved alternator. Kubota's are fantastic little tractors.
That's not a bad idea on the clutch. Trans/hydro oil probably gets a lot thicker than the engine oil when it's that cold, and makes for a much harder start. My old army truck will start right up on the coldest of days, but it won't move until the transmission warms up. At 0 degrees, if you put it in gear within 20 minutes of starting, it just sits there. As for charging, I've got a fairly new dyno and an optima yellow top battery that just fills the space in the tray. Any time I've put the charger on after sitting a couple of weeks, it's always over 90%, until it gets cold.. This was the first time I've had this battery get too cold. I'll keep the maintainer on it at anything less than 20 degrees now. Thanks for watching and for your input! I hope you enjoy your mighty little machine as much as I do mine.
I got tired pushing in the clutch on my b7100hst. and undone the two wires and connecting them together so I don’t have to push the clutch no more. It’s so much better now
It sure does. My old truck sounds angry when it's this cold, and won't go anywhere till the transmission warms up. But once it, or the tractor, gets warm, I wouldn't trade them for anything.
I have no experience with battery operated tractors. You could be right, but since the biggest issue here was cold battery, I don't see how more battery would improve the situation.

@ your very welcome the magnetic oil pan warmer does wonders when it’s in the negatives

Call Hank, he’s got the go go juice by the Drum!!!

Yikes! 0 degrees!!! 😮
Yeah, it was colder than I like lol.
I got tired pushing in the clutch on my b7100hst. and undone the two wires and connecting them together so I don’t have to push the clutch no more. It’s so much better now
I've thought about doing this, probably should.
I run diesels older ones , over coming tge cold factors gets hard.
It sure does. My old truck sounds angry when it's this cold, and won't go anywhere till the transmission warms up. But once it, or the tractor, gets warm, I wouldn't trade them for anything.
Battery blanket.🙂
That would help, but just like a block heater, we don't get enough sub-zero days in an average year to make it a worthwhile purchase.
Plug it in !
I definitely will, for the rest of winter at least.
Thanks for watching!
Recomend a proper battery electric tractor.. range will drop in the cold- but it always runs
