I sent you an email last week off your contact page on your site but hadnt heard back from you. Is it possible to put a locking caster on the z plug for better hill stability? Could you or have you tried having 2 wheels at the front supporting the aerator for better stability. I know I get get on some sick hills on a wright stander or bobcat Z. I know you surf the chemical thread so thought i would try here. Hoping the mods will leave this here.
