Our Rollover Wheels is an attachment you can very easily and quickly clip on to your Rolltack to take it over rougher ground. This simple attachment has an extended wheel base which gives greater stability and 10" pneumatic wheels to give a smoother carriage. No drilling need as it bolts on to existing fixings. You can still use the mounting block feature of your Rolltack with this attachment on as these wheels are also raised off the ground until you tilt and pull your Rolltack. The width of the Rollover Wheels is 73cm, if this doesn't suit we can make to your requirements.
