I'm pricing a job out that has about 40 acres of grass. It's for the most part, all manicured. Part of the scope requires it to be fertilized at least once per season, then as needed. It's a 2 year contract so I plan on pricing in at least two applications. I will most likely go with a 30-5-5 as that's what the local sod farm suggests for good growth. The contract is also based on two cuts per month during the summer, then as needed (extra $$). So it's in my best interest to have the grass growing at it's best. Question is, what's the best way to spread this much and where can I find production rates? I was thinking of going with the lesco ride on. However, it's a large investment and only spreads at 100000 sq/ft an hour - That's still 20 man hours. I've checked out the earthway electric spreaders and can mount one on a UTV. They also hold 250lbs. But I can't find production info on their website. I have no idea how much they can cover an hour. Subbing out might be an option too. A good portion is wide open. A bit of slope work and a bit of a treed area. Finally, this is the most I've had to take on. I'm terrified something will go wrong and I burn the grass or something disastrous. What type of things should I watch out for? I will get a soil test first unless people suggest different.
