WORKING DRAFT (7.45)
The fundamental importance of TRACTOR WEIGHT eludes many tractor shoppers. Novice tractor operators are initially intimidated by instability of tractors with small front wheels and large rear wheels, therefore regularly purchase tractors too light, too small for long term satisfaction. ((Tractors seem to shrink after about twenty hours of operating experience.)) As a newbie operator the stability and strength of a sufficiently heavy tractor will help keep you safe as you learn tractor operation.
The most efficient way to shop for tractors is to first identify potential tractor applications, then, through consulataton, establish bare tractor weight necessary to safely accomplish your applications.
Tractor dealers, experienced tractor owners and TractorByNet.com are sources for recommendations.
Sufficient tractor weight is more important for most tractor applications than increased tractor horsepower. Bare tractor weight is a tractor specification easily found in sales brochures and web sites, readily comparable across tractor brands and tractor models, new and used.
Within subcompact and compact tractor categories, a significant tractor capability increase requires a bare tractor weight increase of 50%. It takes a 100% increase in bare tractor weight to elicit MY-OH-MY!
Shop your weight range within tractor brands. Budget will eliminate some choices. Collect a dealer brochure for each tractor model in your weight range. I spreadsheet tractor and implement specs, often a revealing exercise. I have a column for cost per pound.
Most tractors under 3,000 pounds bare weight operate in residential or hobby farm applications on one to ten flat acres.
Selling a used tractor is easy. Selling multiple light implements in order to buy heavier, wider implements for a new, heavier tractor requires a lot of time. Depreciation on implements is worse than depreciation on a tractor.
When considering a tractor purchase, bare tractor weight first, tractor horsepower second and (narrowly) rear wheel ballast third.
A quality dealer, reasonably close, available for coaching, is important for tractor neophytes. Most new tractors are delivered with a glitch or two requiring correction. My kubota dealer is six miles away. I feel my local dealer continues to add value to my equipment after seven years. Dealer proximity is less important for those experienced with tractors and qualified to perform their own maintenance.
BUY ENOUGH TRACTOR.
TO BE DEVELOPED INTO SEPARATE TOPIC
Safe hillside operation demands more tractor weight than level land operation. Heavier tractors have adjustable rear wheel spreads; wide rear wheel spreads improve tractor stability more than any other variable.
Four wheel drive is essential on hillsides. Four wheel drive supplies increased traction and braking. When descending slopes 4-WD augments rear brakes as tractor weight shifts forward, decreasing rear tire grip.
Compact tractors optimized for hill work have liquid installed in the rear tires rather than air. "Loaded" tires are filled 50% to 75% with liquid, which lowers the tractor's center-of-gravity, increasing rollover resistance. "Loading" two compact tractor rear tires increases tractor weight 300 pounds to 800 pounds over weight of identical two tires inflated with air. Some prefer to ballast rear wheels with iron wheel weights rather than tire liquids.
