## Questions & Answers

**Q: Battery in atv is low and in the front; from the reviews the included cables won't fit.  what are some work-arounds?   2nd battery?  portable charger?**
A: I’m not sure what you mean by won’t fit. The cables are about 6 feet long and have spring loaded clips that simply grip the battery terminals. My battery is in the front of my mower.

**Q: I need to spray grazon next hl at the rate of 24 oz of water diluted product per acre. at what rate/pressure do i need to spray?**
A: You will need to calculate your flow rate (Gallons Per Minute) , the width of the spray pattern, know the speed of the pulling vehicle and the concentration of the mixture. example 4 mph (1.14 feet per second per MPH) will travel114 feet in one minute, with a 6 foot spray pattern spray pattern will spray 2.2 gallons per minute and will cover 2736 square foot. there is 43,560 feet in a square acre. it takes 15.92 minutes to cover the acre.  in that amount of time you will spray  31.84 gallons.  To get the approximate spray you will need to add 12 oz to 16 gallons spray half and repeat the process on the second half.

**Q: how well does this work on Hills**
A: our property is hilly no issues here

**Q: Will this fit huskvarna rzt54 riding mower?**
A: It fits my quad which is much larger than your mower. I would definitely assume that it will fit your mower as long as you have a trailer hitch.... because the sprayer is a trailer
