Peter Martens FarmerRead this review“We’ve been able to do an optimum job of soil preparation a higher percentage of the time because our rotary cultivator (KUHN HR 4504 Power Harrow) allows us to work the ground without losing as much moisture as you have to lose to use a disc effectively. The cost of operation is lower. The wear parts and tines are much less expensive on the KUHN than they were on the competing model. The KUHN is just a more robust and durable machine."
Rob Platfoot Facilities Manager at Eldora SpeedwayRead this review“It doesn’t take as long to work the track now. The harrow (KUHN HR 4004 D) is a major asset because you can add more water to the track when it’s 100 degrees outside to work it into the soil to last awhile. Vice versa the harrow helps the track dry out on rainy days, when it’s too wet to dry by itself."
