加拿大采购需求：履带式耕耘机、Grace 50HB旋耕机、旋耕机出售、耕耘机规格、园艺耕耘机评测、最佳旋耕机

I'm interested in getting a detailed quote for a 50 hp hydraulic crawler tractor equipped with front loader bucket and excavator boom bucket attachments. Additionally, I would like to inquire about the extra costs associated with including a trenching knife, auger, and lawn mower attachments in the order. Could you also provide shipping costs to Blackstock, Ontario, Canada? Furthermore, I'm curious if purchasing through Aliexpress tends to be more economical compared to direct ordering. Any insights or recommendations on this would be greatly appreciated. Looking forward to your prompt response on these details!
