On my JD790 the mid PTO speed is around 2000 RPM at PTO engine rpm. Hope this helps.

Check with any local tractor dealers, here in Central Virginia, most can get one made by either Long or ATI, I also have heard that the are also used on skid loaders, so dealers of them may also be a good source. Hope this helps.

My 790 does the same, its a characterist of the design of the type of power steering used on the tractor. You will notice that you can turn the wheel when the engine is off, and the wheels will not move, you are just passing hydraulic fluid through the valves.

Hope this helps.

Here is another suggestion - When I put the rear hydraulic outlets on my JD790, the 3 point didn't work, got concerned that something had got into the system. Then remembered that air compresses, upped the rpm to around 2000, worked the 3 point, to my surprised, it functioned. I guess I had a large air bubble. Same thing could be happening when you disconnected the hoe.

Terry, I don't want to offend you, but do know why there are so many people with education degrees out there doing everything but teaching? In most places, teaching doesn't pay as well as manufacturer's reps, and I don't know if you have been in the classroom lately, but teachers don't get much respect, especially in high schools. I'm not a teacher but do work for a school system, can't recurit teachers at $30,000 a year, losing the teachers we have because the students are threating them or they are out of control. But you are right about manufacturer's reps - good many don't know the product.

David, the price quoted on the 790 is a little high, I got a 790 last summer with rear and mid PTO, SCV, and loader with 54 in bucket for $14,900. As for his 50 hour service on the 790, 50 hour service includes engine oil and filter change, grease job and checking the other fluids. Don't have my shop manual with me, but don't remember doing much else. His $500 sounds like a tractor with hydro where the gear fluids and filters get changed also.

Check with your John Deere Dealer - the parts manual shows cab parts being available. If I recall correctly, it appears to be canvas sides.

I have also seen snow plow blades made from the ends of 275 gallon oil tanks. You have to reinforce with angle iron and make a blade from flat iron. They work good. You just have to be careful cutting them up.

I also have a JD790, and I also notice that my loader will also settle down. have never left it up full height and timed it though. Usually about foot off the ground, come back later and its on the ground. Never gave it much thought, just though it was natural leakage around the spools.

For everyone's information, I received a customer survey from John Deere yesterday, asking me to rate the tractor, the dealer, and a space for other comments. I have a JD 790 and purchased it in May. Has anyone else gotten one? Since I haven't had any problems, except slow delivery of the rear hydraulic outlet from the parts depot, I had to rate them pretty good.

Some additional comments, having pulled a travel trailer 48k in one year, I offer some observations. Sway controls help travel trailers with sway from passing trucks and the winds due to the flat sides. I have not experiences this type of sway from equipment trailers, I guess because the side surface area is less. Equalizer hitches help spread the tongue load to the towing vehicle's front wheel, thus better control but don't do much for trailer sway, but does help prevent the trailer from wagging the tow vehicle. I have used 3 types of sway control, the Reese type that attach to the equalizer bars and trailer frame, the friction type and the electrical - pendulium in a can type that operates the trailer's brakes. Like the friction type best as it does not depend upon weight on hitch bars to function and they are easily adjusted to conditions and needs. I have found with equipment trailers, proper loading and weight distributing prevents most sway.

I have a JD790 with the 70 loader and it definitely will lift the front end off the ground. If I tip the bucket with the cutting end down, it will lift the front end clear of the ground to the max of the cylinder travel. I got mine in May, have just over 100 hours it now, moved an intire hill over the summer from one side of the drive to the other to increase the turning radius. No problems, just one great tractor.

Price in ball park for tractor and loader - paid $15,000 for 790, FWD, DSCV, mid pto, 70A loader, 54 inch bucket and R-4 tires in May 2000. Worked with 4 dealers, and all were within dollars of each other, and they knew of the competition. Hope this helps.

If you are looking to repair a cracked block on an old tractor that does not have a pressurized cooling system here is what I have done. Used epoxy to close the cracked with some fiberglass cloth to bridge the gap. Clean the block real well first than go at it. so far its held over two years, but I'm not using the tractor except to putt around.

Getting things out of the bed of a pickup truck is always a problem, usually can't lift them high enough. I use the loader (using chains or straps) to lift the load off the bed floor then drive the truck out from under the load. Just keep an eye on clearances as you drive off, dips and bumps always cause problems.

With the wheel bolt problems showing up
, it may be to your advanatage and piece of mind to take a technique from the transit industry. Many now are painting index lines on wheel nuts and wheels after they are properly torqued. If one should start to back off, then the index lines will be out of alignment. This technique also permits a visual check and can be done each time you go to use the tractor. I have done this on my JD790, not that I have had a problem, but I do find the front loosening up on the front after extended use of loader.

I also have a JD790, and do not think I would want anything over 1000 pounds hanging on the rear, wouldn't be able to keep the front end on the ground. I have used a boom to pick up several desiel engines weighting in around a 1000 pounds and had to have the loader bucket full of cinder blocks to keep it on the ground. Look around, there are not many implements for cat 1 tractors that that heavy, the mower is about the largest.

In Virginia you are suspose to pay the sales tax on out-of-state purchases when you file your income tax. On tractors and farm machinery you can claim exemption from sales tax if the equipment is to be used on a "farm".

In the operators manual for my John Deere 790 they reference blocking down the clutch petal for extended storage (like months, they even have a kit with rust preventative to be used for prep for storage). They even have a metal oblong ring that slips over a protrusion on the clutch petal and foot board for the sole purpose of locking the clutch petal down. I guess you could block the clutch anytime you parked. Hope this helps.
