MicroTrac is a small scale, walk-behind version of [[LifeTrac]]
 
=Industry Standards=
*The [http://www.abbysguide.com/ope/reviews/39-0-1.html BCS Tiller] is the main competition.
 
=Tools=
*Tiller
 
*Mower
 
*Chipper
-Laimet conical screw design. Makes nice big, uniform sized chips.
 
=Engine=
The engine will be a modular removable unit consisting of engine, fuel tank, hydraulic pump, hydraulic reservoir, and frame. The frame will be the hydraulic reservoir, made out of 4x4" square tube.
 
[[Image:Hydgearpump.jpg|thumb|pump]]
 
==Specifications==
Engine should be a 12-20 hp 1 cylinder diesel engine, with air cooling. The engine will run the hydraulic pump.
 
We have a 17.5 HP engine.
 
Dimensions: 18x16x13"
Shaft: 1x?"

=Power Calculations=
[[Image:microtrac_pump860.jpg|thumb|0.86 cu in pump, 3000 psi rated, 3600 rpm, 12.6 gpm at 3600 rpm]]
*From [https://surpluscenter.com/] - Pumping = 1 Hp = 1 GPM x 1500 Psi - (linear relationship i.e. 2 GPM @ 1500 Psi = 2 Hp)
**For the above pump, 14.2 gpm with 3000 psi indicates 28.4 hp requirement
*Hp to drive hydraulic pump = Psi x GPM / 1714
**For the above .97 cu in pump, 3000*14.2/1714 = 24 hp
**If we run at 2200 psi => 18 hp required
**For .86 cu in pump, need 3000*12.6/1714 = 22 hp
**For the same with 2500 psi, 18.3 hp
