Kuhns tie grabber

New to hay talk. I ran a kuhns AE 15 off my NH bc5070 this summer. Nice setup and makes a good bale of hay. I had my kuhns 615 tie grabber running off a rented kubota ssv 75. Great visibility to see the grabber do what it needs to do. This is an 8400lb machine and still I felt the grabber with 15 bales of hay was way too light to handle it when I got the bales in the air. Anyone use or recommend a track machine with success or is adding weight to a wheeled skid steer the best route? Transitioning from kicker bales and have put up 20-25,000 yearly for 18 years.
