Looked at a 2001 Massey 8250 today. Is had the sisu engine. All the information I have seen shows the MF 8250 as having a Valmet engine and the MF8240 with the sisu. What gives? What would the Challenger comparable models be to these tractors and any impressions or experiences you have of these models? Thanks.
Valmet? Sisu? Massey 8240-50
