To those out there who installed the shims on the JD 790's did the dealership say anything about the effect this would have on the warranty. I sp/w JD corp today and was told that if you put a JD part on the tractor that it shouldn't void the warranty. I still have 1 year left on warranty and don't want to void it. <br>
<br>
Was also told that if you have the dealership do the servicing and they differ from the "suggested" intervals, fluid in the book that it doesn't effect warranty either as they may know what works better in particular area and local dealership has the say so to do that. <br>

I have hooked up equipment to tractors in the past. Have an agri background and have hooked up 3-point equipment to the 7 and 8000 series JD tractors, they weren't half the trouble that I am having hooking up 3-point equipment to the 790. Can not back up and hook the arms on one side, attach the center link and then have the other arm fit on like I have done on bigger tractors. Have to spend 30 minutes, break my back and use a pryer bar to get it to finally attach. Is it me, the tractor or something else that I might need to know about. <br>
<br>
Thanks

I have a JD 790 w/FEL, and R-4 tires. Will be buying a disk, but with the lift capacity of 815 lbs, having trouble finding a strong well built disk within that capacity. Found one built good and heavy for food plot work, made by Ag-Meir its 5 1/2 ft wide and weighs 765 lbs, is this going to strain the tractor and will the R-4 tires pull that disk effectively. Ag-meir also has a 5 ft disk that weighs 540 lbs would this be a better choice. <br>
<br>
I am looking for the heaviest disk that I can get away with for the best results, don't want to just scratch the surface.<br>
<br>
Anybody out there have any experience on the above. <br>
<br>
Thanks

I have a JD 790 '03 model so it has the smaller engine. Use a 60" box blade with industrial tires with good results, at deer camp on clay ground to rpr a road was able to get the box 90% full and still had power and traction, with a box blade you will need to get it leveled up and set it for the best cut angle-front to back tilt- for particular soil type, as for rocks and sticks don't have one but have heard that rakes are best but have used box blade for same

For the 790 the only part that I am concerned about are the fuel injectors assy. I have a buddy with a JD 4510 4WD and he bought the 3 year ext warranty for that reason as his dad is a serious lawnscaper for his part time job with a NH tractor about 55 hp, can spread a dump truck load of dirt in 8 minutes with box blade, has had fuel injector problems and on his past tractos he trades every few years with about 3000 hours has had trouble and one set of injectors cost more than the warranty. And after some more investigating that seems to be the one PRICEY breakdown on tractos that happens pretty regularly, like transmission in chevy trucks with more than 70k miles. So just investigating to see if warranty avail and weigh the pros and cons.

Has anyone had or heard of any other pricey breakdowns on the JD 790 that could influence buying a warranty if avail ?
