""You might want to check your tractor width with your plans for your vinyard row spacing to make sure that everything fits for your planned use. Most folks around here use quite narrow tractors in their commercial vinyards. Maybe you can buy a narrow tractor at a later date? Also, note that the R1 tires will have more width adjustability than the R4 tires. Good luck with your project.""
I've got to disagree with you on tire spacing, I'm not sure about the
L3130, but on my 5030 with R4's the tire/rim offset is adjustable. I'm in the house and not in the shop so I can't tell you the exact offsets, but there a 4 positions. The tractor shipped in the extreme inset position and I dismounted the rims and put them in the extreme offset position which was almost a foot wider that the shipped width. I can look in the manual tomorow and give you the exact offsets, but you can call your dealer and if they are knowledgable they should be able to tell you.
It dosen't matter whether you get R1's and I don't know what an R1 is or R4's, the offset is in the rim, not the tire. Looking directly at the brochure for the
L3130,
L3430,
L3830,
L4330,
L4630 and
L5030, on page 31, Optional tires are listed as "Galaxy, Turf Tire, Industrial (which is R4) and Agricultural Tire. There is no reference to R1. I'll stand to correction on any of the above points, however. I've included a picture of the butt end of my 5030 so you can see the R4's. The extreme offset is also evident
