I have quite a few. Most ERTL. Here are a few photos I already had on the PC. The 70 piece playset is a good starter. However, some of the tractors (the tracked one is around HO by my math) are oddly scaled in those budget ranges.
However, I think SpecCast is the best there is. Unlike the high detail ERTL models, they can still fit standard implements.
Massey Ferguson 8730S
This is from the "Authentics" series, which has far more detail than the average 1:64 ERTL you'll find in stores. My local Deere dealership had this one on sale last year for $20--and they move toys slowly there, so they may still have some more. MSRP was near $35-40.
Scale Models are made here, but they're a little basic in the detail department. Joseph Ertl founded the company after selling his namesake toy company off in the early '80s.
This Minnieapolis Moline is pretty early, and was retooled from a 1980s era plastic model (up until the very late '80s, everything they made was unlicensed and plastic--with MM being one of the first licensed brands).
If I recall what the original owner told me correctly, he says the decals are aftermarket, since it was still a generic casting at the time.
The early '90s Ford/Versatiles are a pretty big improvement.
They did a few John Deere models as well--one of them being a 5020. Note they never did it with yellow wheels to avoid getting sued.
Greenlight has some decently detailed tractors in a series called "Down on the Farm", but their Case and White/Oliver/Minneapolis Molines are generic. Fords remain the only licensed ones they offer. Hitches are also too small for ERTL implements.
This is an 8N with cab.
ERTL has a few trucks, but they're pricey at $10-12 for no interiors at all. Greenlight's are around half that, but the quality leaves a bit to be desired. The AMR IndyCar Safety Team truck has a rear axle that is a hair's width short, and the wheels don't attach well.
Only 1:64 UTV is by ERTL. Don't know why they didn't keep the Polaris license up and issue 1:64 Polaris.
