This morning I put my 3215 FWD through the paces. After clearing and disking, I am levelling and smoothing a 3 acre plot of flat ground. Today I was pulling (drawbar) a 9-foot wide spike-toothed harrow. The harrow has a steel frame and weighs around 450 lbs. It creates quite a drag when encountering deep, soft sandy dirt. Here's some numbers:
Tractor empty weight w/FEL: 3100 lbs
Tires: Industrial, Carlisle Trac-Chief, not filled
FEL: carrying 900 lbs of rocks
Rear weight: 66" 510 lb box blade
RPM used: 2400
Engine oil: Mobil 1 synthetic, 5W-30
Fuel additive: Stanadyne pro-formula
Weather: 55 F, sunny
After significant hours of driving this rig, one becomes sensitive to sounds and any changes in engine noise. There is one section of this plot that has particularly soft, thick, deep soil. I knew it would create a HUGE drag on the harrow. Sure enough, the 3-cylinder, turbocharged Mitsubishi diesel began feeling the load. Under great strain, the engine slowly dropped to 2150 RPM and the tires spun, but forward progress was maintained. I could hear the faint whine of the turbo. It pulled clear through it, and on to easier ground.
It amazes me, the power and torque this engine produces. The water temp never increased, and the motor was perfectly smooth.
Unfortunately, the ground was rather dry and the tractor got kind of dusty. So I had to wash the whole thing, dry it, then re-polish the wax finish with a soft cotton towel, and re-dress the tires and all rubber seals with Formula 2001 (Armor-all type product). But, tomorrow night I have more levelling to do, and the tractor might get dirty again!
