I built a tow bar ( at leaset that's what I call it) It is a 3-point attchment & I can enterchage the receivers off of my truck hicth for the size of ball I need or farm hitch. I'm always moveing trailers around since I have 6 of them. I've found this method to be very useful & quick as a snake. back under-raise & go. My 2 cents

I have a John Deere 5020, which I purchased at an action a year ago (the tractor is fairly old). I finally got a bushhog (fifteen footer) for the tractor and when I went to hook the PTO of the bushog to the tractor, I had a shocking surprise! The PTO on the tractor is a 1000 RPM with a 20 spine PTO staff where my bushhog as the 540 RPM 6 spline staff. An adapter is not an option so I was wondering, does the 5020 model have the capability of interchangeable ptos? Or am I left with the possibility of buying another tractor.

Hi guys, a long stroke engine has a longer distance from the center of the crank to the center of the connection rod journal. This would give more torque to the crank for a given amount of pressure on piston crown. It kinda like using a cheater pipe on a breaker bar. Another point is that the pressure (psi) above the piston is not linear. This pressure, at full burn, is the highest when the volume above the piston is the smallest. As the piston descends and the burn area increases the psi per sq inch decreases as burn force is applied to a larger surface area. Gasoline has an expansion factor of about 4, that is 15psi compressed to 10 to 1= 150 psi at end of compression stroke. Light this off with the spark plug and will expand to a max of about 600psi and then begins to drop off as piston goes on down. The louder the exhaust the higher the more residual pressure left in the cyl is when the exhaust valve opens. This is why racing engines have a louder exhaust then basic work engines that are designed to get as much pressure per pound of fuel as possible applied to the piston instead of out the door. The downside of this, of course is reduce volumemetric efficiency. Peter, your description of the connection between volumemetric efficiency and torque was terrfic. Hope the above makes some sense.

Hi guys, as far as I know all 6 volt Ford and Chy products were pos. grounded.
GM used neg grounds on their 6 volt cars. Ford and Chy switched to 12 volt in 1956 and went neg ground then. Chevy went 12 volts in 1955 (exception 6cyl corvette) and stayed neg ground. Chy went to alternators in 61, chevy in 63 and Ford used some in 63 and went full alt in 64.
It is ok to run a 6 volt starter on 12 volts for short burst's, keep in mind that the amperage draw will be higher and the engine will turn over faster.
When switching from pos to neg ground the amp meter and ignition coil leads need to be be reversed and the generator polarized to match battery polarity. Failing to repolarize will put the battery and generator in SERIES giving you 24 volts instead of 12. One advantage in going from 6 to 12 volts is that ALL of the OEM wiring is now of a heavier gauge (twice) of whats needed. An extreme rarity these days.

regards,
george, keoke

It would be a shame for them to discontinue the 790. It is such a nice basic tractor with enough power and still a nice size at a reasonable price. JD is already limited in the 30hp and under market, it doesn't make sense that they would further limit their selection in that size and hp range unless they are planning on introducing another model or two between the 4100 and the 4300 with more hp than the 4100 and less size than the 4300.

Thanks for the info. You may well be right, and JD just relied on common sense not to break the motor. In fact, I'm going out to see an 830 today and will look to see if there is anything special. The most common metering system was nothing more than a calculated volume. Ether under its own gas pressure can only put so many molecules of itself into this space - which could be something as simple as a a short length of pipe that the ether can was either screwed into or sprayed into. I have also seen it as a chamber that you put an glass vial of ether into and then screw it in until the vial breaks. Vapor pressure then fills a second chamber with only a certain amount of the gaseous vapor. A real simple concept that limited the quantity of ether - although it could be defeated in the field.

Frank, I forgot one thing; the spout on my little pump came threaded for an ordinary garden hose to attach, so I use about a 6' piece of garden hose to pump the fuel into the tractor.

Frank, the B2910 now has the telescoping lower links on the 3-point. I'm not sure whether the same lower links could be used on other models, but they sure look like they'd fit the B2710 at least.

We have sold Kubota's both ways but we do not normally stock the bi-speed at this time. We have never worked on any that we have sold and I can see what the other dealers are talking about as far as more parts more things to wear out. Let's just look at your needs of the bi-speed turn. Do you have a lot of hills you mow that you would use four wheel drive? Would it be for loader work on hills? If you don't have the conditions or need to use four wheel drive all the time you wouldn't get any advantage of the bi-speed turn unless you just wanted to use it because you have it.

This is a question for Murf or any of you golf course experts out there.I've noticed while playing golf lately,(i find the time once in a while)that on short holes where you get a lot of divots,they place pails filled with a mixture to fill in your divot.It appears to be mostley sand and i assume has seed mixed in.Since i occationaly take a divot with my mower,i thought it might be handy to have a container of this on the truck.Is this a prepared mix you can buy or do you just mix up your own.

The L3000 is a great machine. Bought mine 3 days ago, however, I have been around these machines a long time. They are the best tractors in their class.

I received my safety latch 8/2. It took longer to get to the shop than it did to install it. I will use it just in case. I would sure hate to have somebody get hurt. I have had my 4300 since March and have had no problems. I am still amazed at how much work it can do and save me. I can understand some of your frustrations, though. I bought a new JS60 lawn mower w/ Briggs engine from the same dealer I bought my tractor from. The engine blew up after 3 hours mowing. I took it back and the dealer has offered to replace it with a new one or let me apply the purchase price to JX75 w/Kawasaki engine at my request. I guess I will spend the extra money to get a Kawasaki engine but I would have preferred that the original one work right.

Roger thanks for your suggestions but still not sure
The gears that keep breaking are the top spindle bevel drive gear and the spindle bevel imput gear it seems though that either a snap rink is breaking or a spacer is breaking ang its getting into the gears which in turn is breaking the gears

Don't know about your machine - and it depends on which wheels that you have, but most tractors with turfs will have a different width if you jack up the rear and either reverse the wheel on the axle (reverses the tread)...or swap the wheels from one side of the tractor to the other keeping the same tread direction.

That little problem, if it is a problem, may get better with age, but I think it will always be there to some extent. If those gears are not lined up just right, they don't fit together and you need to either press very lightly, as stated, on the hydro pedal to turn them, or release the clutch, if you were using it to start with, step on the hydro pedal, release it, and depress the clutch again to shift the range selector lever. Some folks use the clutch, like the manual says, and some don't. You don't really have to use the clutch as long as you are stopped and are not depressing the hydro pedal.

I've dealt with Key's on a few snowmobiles and got good prices but never had any service work done their. Last fall I was going to purchase a Cub Cadet tractor, loader and mower. They advertise they will deliver anywhere and I'm about 80 miles away and they would not deliver and wanted me to install the loader or pay them $100.00 to install it. I went to another dealer.

I've heard of conversion kits for bringing rear PTO to the front, but not from the mid-PTO. Of course this doesn't mean anything. Since, I don't have a mid-PTO, I've never looked. If nothing is available, perhaps it's because implements intended for mid-PTO use tend to be pretty specific to a tractor and already come with a PTO hookup.

Yes, 3ph blowers are a pain in the neck. However, I've never figured out how clear snow without using both the blower and the loader. Changing back and forth in cold weather would be a greater pain for me, so I stick with the 3ph blower.

Couple of questions:1) Mower seems to 'wander'. Replaced rubber column bushings, but steering box seems to have 'slop' in it. Is there any adjustment to the box? 2) Where is a good place to buy a service manual (rather than the $75 dealer item)?3) How 'hot' should the mower deck gearbox get? Mine is pretty hot. You can't hold your hand on it for more than a couple seconds, but the paint is not discolored.
