Thanks guys, so the grant is a California air resources board program. It is an incentive grant to get old non tier 4 final engines off the farm/earth. Look up carl moyer grant. In evert county they run it a little different but luckily im is a small tractor having market....they reimburse me 80 percent of the cost after i complete all the requirements. It is a like for like but can go up or down 25% in hp. They use a cost effectiveness calculator that determines your ranking and they give money form number 1 on down till the run out of money. San Diego has about 3 million to give.
